punctate, scarcely reaching to the part of the elytra where the 

 striae commence. Elytra smooth, shining, and impunctate, with 

 seven deep impunctate striae besides the marginal stria ; the striae 

 become deeper towards the apex ; there is no abbreviated sutural 

 stria ; the first two striae run alongside up to the apex ; the third 

 and fourth join together a short distance from the apex, and 

 their united line goes on for a short distance ; the fifth and sixth 

 do the same ; the seventh runs the whole length, becoming wider 

 towards the apex, where one or two circular punctures or foveas 

 occur ; the marginal stria has a number of these impressed on 

 it ; it runs up to the apex, where it widens much, and is divided 

 by a raised line, which proceeds from the emargination near the 

 apex; the marginal ridge of the elytra is rather broad and pro- 

 minent ; a faint stria runs along the under margin of the re- 

 flexed edge of the elytra ; the interstices between the striae are 

 convex, but more so on the sides and towards the apex than at 

 the middle and base. The under side is smooth, polished, and 

 impunctate, except two minute punctures, one on each side of 

 the middle of each segment of the abdomen ; the segments also 

 show depressions along the sides. The legs are ferruginous- 

 brown. 



I have named this interesting species in honour of my es- 

 teemed correspondent, M. Obert, of the corps of Cadets, Paulow, 

 St. Petersburgh. 



Ochyropus, Schiodte. 



Prof. Lacordaire disallows this genus, not considering it suffi- 

 ciently distinct from Scarites ; the only differential characters 

 given being, that the second joint of the labial palpi is enlarged 

 on the inner side and prolonged at its anterior internal angle, 

 that the mandibles are toothed in their whole length, and that 

 the last joint of the tarsi is of the length of the preceding joints 

 united. The last of these characters is incorrect; the last joint, 

 although long, not being so long as represented, and scarcely 

 longer than that in other species of Scarites. The second cha- 

 racter (the toothed mandible) is unimportant, even although it 

 were not found in other species of Scarites (which it is). But 

 the enlargement of the second joint of the labial palpi is of 

 more value : it is long, broad and flat, expanded on the inner 

 side of its anterior angle, and strongly ciliated, so that it seems 

 to be almost a second maxilla, and no doubt serves the purpose 

 of such. This seems a sufficiently important character to justify 

 us in retaining the genus as distinct, the rather that the fades 

 of the insect is different from that of Scarites. Its thorax is
