6 Coleop Genera

Buprestis - Body firm; head inserted in thorax to eyes; antennae short filiform serrated; palpi very short, filiform; mandibles entire at tip; maxilla bifio at the extremity; thorax with its posterior edge applied to the base of the elytra, the posterior angles not elongated; feet short. P22 & 30.43

Lycus- Head retracted; antennae approximate, much compressed, more or less serrated mouth small produced into a short rostrum; maxillary palpi much longer than the labials, terminal joint triangular, truncated; mandibles at tip entire and acute; elytra thin & flexible, nearly of equal breadth or much enlarged towards the tip; thorax receiving & curving the head, rounded before; penultimate joint of the tarsi trilobated. p. 23, 43.

Cryptocephalus-Geoff-(Chrysomella Lin.) Body short, robust cylindrical; head vertical; antennae inserted between the eyes, simple, filiform, more than half the length of the body; palpi terminating with a cnic-cylindric joint, maxillary palpi very apparent. P. 29, 40, 43.

Cychrus, Fab. Head narrower than thorax; external maxillary and labial palpi dilated, compressed & securiform; labrium elongated very profoundly emarginate; labium very large, prodoundly emarginate, not wider at base than at tip; mandibles narrow, elongated bidentate near the tip; thorax cordate, slightly or not at all elongated each side; and not extended behind; abdomen robust convex; elytra entire, not divided at the suture, carinate each side and embracing the sides of the abdomen; P. 13.

Sphoeroderus Dejean. (Cychrus Fab). Head narrower than the thorax; external maxillary and labial palpi with the last joint dilated, securiform compressed; labum elongated, profoundly emarginate; labium very large, profoundly emarginate, not wider at base than at tip; mandibles elongated, narrow, bidentate near the tip; thorax rounded, not elevated on the sides, nor extended behind; abdomen robust, convex; elytra entire, not divided at the suture, carinate each side, embracing the sides of the abdomen; tarsi with the 3 basal joints in the male dilated.-13.

[Scaphinotus?] Dejean (Cychrus Fab.) Head narrower than the thorax, external maxillary, and labial palpi with the last joint dilated, compressed, securiform; labrum elongated profoundly emarginate; labium very large profoundly emarginate, not wider at base than at tip; mandibles elongated, narrow, bidentate near the tip; thorax with the lateral margins reflected, posterior angles extended; elytra entire, not divided at the suture, prominently carinate on each side, and embracing the sides of the abdomen. p 13.

Malachius Fab (Cantharus Lin) Body furnished with cocardes; head retracted to the eyes within the thorax; antennae 10 jointed, filiform serrated; mandibles emarginate labrium entire; palpi filiform; tarsi simple; nails with a tooth beneath; elytra flexible. p 24.

Enoplium Lat. (Tillus Ohio) Three last joints of the antennae dilated, forming a deeply serrated mass; the 4th, 5th, 6th, 7th, & 8th joints very small; palpi prominent securiform, body cylindrical; tarsi with but 4 very obvious joints; penultimate joint bilobate. p. 24.

Boletophagus Illiger (Eledona Latr.) Body very rough oval convex; head rather large, without a neck; eyes almost bisected by the prominent margin; antennae arouated, inserted beneath the margin thicker towards the tip; mandibles destitute of the horney nail; palpi filiform, terminal joint of the maxillaries cylindrical; thorax transverse, as broad as the elytra, the anterior edges projecting forward; scutel small, rounded; elytra covering the longum.
