The contrast between the very coarsely and deeply punctate pronotum and the finely and vertically rugulose or strigilate sculpture of the sides and under surface of the head is one of the greatest wliich I have observed in two adjoining surfaces of the same insect. I cannot see any species to which it can be allied, but it may for the present be placed immediately after hirtas Oliv., from which it differs by its more dense pronotal punctuation, and in the elytral intervals not being serially punctulate ; it also appears to have a much longer beak.

On eoniparing this specMnien with Dr. LeConte's type of rohi/sfxhis, I had come to tiie conclusion that it was distinct on account of the narrower form and slightly ditferent vestiture, and this opinion is somewiiat strengthened on reading the original description M'herein it is stated that the femora are not toothed, and the second and third joints of the funicle are nearly etjual. It is, however, very closely allied to rohitstiiliis which is (It'scril)e(l from Kansas. The second ventral segment is as long as the third and fourth together, the latter equal in length.

Of Elleschus there are in my cabinet three forms, viz. : A small species 1.8 mm. in length, pale in color and very densely punctate on the pronotum, abundant near the Atlantic seaboard ; another represented by eight very uniform specimens from Kansas, 2.4 mm. in length, with less dense pronotal punctuation, and a third, above described, which differs from the other two by the distinct punctures of the beak and the much coarser pronotal punctuation, as well as in its more elongate cylindrical form and larger size. The first of those above mentioned is probably ephippiatns, the second may be distinct and if so is probably undescribed.

The smallest species described troni our territories and somewhat allied to to)))entosiiSj from which it ditlers in its smaller size and mottled elytra; the basal carina properly terminates at the basal angles which are slightly callous, but the lateral edges of the i)ronotiim are acute and well marked tor a very short distance anteriorly, much less however than one-third the pronotal length. The posterior margin of each elytron is distinctly sinuate near the interior apical angle, causing the latter to have the form of a very small acute cusp.
COLEOPTKRA. 195 NOTES AND ERRATA.
Part I.
Page 8. — The species described as Harpalus opaciis is in reality an Anisodactylus. Tliere is one discal puncture on the elytra at the posterior third, and two setigerous punctures at each anterior angle of the epistoma. The specimen described is not a male but a female ; I have since discovered a male amongst some discarded duplicate material ; it is more shining than the female type. Page 11. — //. convicior should probably be placed as a synonym of ccmonictis, and canonicus, Instralis a.i\cl' (enescens placed ks varieties of riridilEiieus, at least until renewed study can be made with greatly increased material.
Page 31. — I am informed by Mr. Pauvel that Dr. LeGonte's Edaplmf nilidus has not four basal pronotal foveae but six, and that A\ luadentus is probably a synonym. In order to decide this question, however,it is necessary to examine Dr. LeConte's original type of E. iiitidus which I have been unable to do.
Page 50. — P/. parndum is perhaps a very small and singularly deformed specimen of excavattmi, a"nd the name should therefore be entered as a synonym of that species until future collecting can decide upon its true relationship.

Synonymical notes.
Through the kindness of M. A. Orouvelle, who has provided me with types of many species of this family, I am enabled to x^i't'sent the following remarks:— Page 72. — Sil. quadricolUs Guer. — This is not the species indicated but CathartiiscassmReiche.
Page 73. — ^il. advena, rectus, and 0])acidus should be read Cafliartiis adrena, rectus,andopacidus.
Page 76.—By renewed observation I am quite positive that Prostomis americuna Cr. is an absolute synonym of manddndaris Fab.
M. Grouvelle considered that Cath. opacidus Lee. might be a synonym of Cath. ijitadricoUis Guer., but from a direct comparison of the types I find that they are quite distinct. The above author also informs me that Lwrnoph. loiKjicornis Mann, is a synonym of piisillus 'J, .
