THE LEAF BEETLES. 



1233 



2285 ( ). Coptocycla p lic ata Bon., Moiiog. Gassid., Iir, 1857, 49:'>. 



Form of Ueolor. Above black, shining, the margins of thorax and ely- 

 tra, except humeral angles of latter, pale yellow. Tinder surface pale, the 

 center of abdomen darker. Elytra each with a round, deep fovea on mid- 

 dle; punctures coarse and shallow. Tarsal claws pectinate at base. Length 

 6-7 mm. 



Throughout the State; scarce. May 12-, June 10. Swept from 

 roadside herbage. 



LXXX. Chelymorpua Chev. 1834. (Qr., " tortoise + shape,") 

 This genus contains large convex species, with the margins of 

 thorax and elytra comparatively narrow, the former bisinuate at 

 base and emarginate in front so as to leave the head partly visible. 

 The presternum is grooved and prolonged behind the front coxa?, 

 the apex fitting into a notch in the mesosternum. One of the two 

 recognized species occurs in the State. 



2286 (7109). Chelymorpha akcus Herbst, Col., VIII, 1801, 278. 



Oblong-oval, convex. Bright brick red; thorax with 

 four black dots arranged in a transverse row, and often 

 two others behind them ; elytra each with six black dots 

 and a common sutural one near the scutellum ; under sur- 

 face, legs and outer antennal joints black. Thorax and 

 elytra alutaceous, the former finely and sparsely, the lat- 

 ter more coarsely and rather densely punctate, the punc- 

 tures not in rows. Length 9.5-11.5 mm. (Fig. 554.) 



Throughout the State; frequent. April 7-Au- 

 gust .11. Occurs on milkweed and on wild potato 

 (Ipomwa pandurata L.) . It is well fitting that this 

 large and difficult family should close with this prettily marked 

 species, which is among the largest and most striking of our native 

 Chrysomelids. 



Family LTV. BRUCIIIDZfl. 



The Pea and Bean Weevils. 



A small family of short, thick-bodied beetles, all but one being 

 less than one-fourth of an inch in length. They are closely allied to 

 the Chrysomelids, but differ from most species of that family in 

 having short serrate antenna- and the tip of the abdomen exposed, 

 and from all in having the mentum distinctly pedunculate. They 

 also resemble very closely the Anthribidie, a family of the Rhyncho- 

 phora or snout beetles, but the labium and palpi are of the ordinary 

 form and the head is but little prolonged in front.
