858 FAMILY XLII. — CLERID.E. 



the males of most genera the inner angles of the first two joints of 

 the antenna! chib are much prolonged. Ten genera are represented 

 in America north of ^lexico. six of which are known from Indiana, 

 while another may occur.

 thorax yellow. XIII. Obthopleuea.

IX. PHYLLOB.^i^NUS Spin. 1844. (Gr., "leaf + to go.") 



Eyes emarginate on inner sides ; last joint of both pairs of palpi 

 very elongate, triangular ; labial palpi a little larger than the maxil- 

 lary ; antennte 10-jointed, joint 7 very small, joints 8, 9 and 10 much 

 larger than the preceding, depressed, last joint ovate, club shorter 

 than funicle; tarsi slender, short, fourth joint rudimentary, claws 

 strongly toothed at base. Two species are known from the United 

 States, one of which occurs in Indiana. 



1641 (5210). Phyllob.^nus dislocatus Say, Journ. Phil. Acad. Nat. Sci., 

 V, 1825, 176 ; ibid. II, 284. 

 Elongate, subcylindrical. Black, moderately shining ; an- 

 tennae, mouth parts and legs yellow, often more or less fus- 

 cous; elytra each with an oblique pale yellow stripe extend- 

 ing from humerus to suture at basal third, thence along su- 

 ture to just behind middle, where it usually connects with a 

 narrow undulate yellow crossbar; also usually a small yel- 

 low subapical spot. Thorax subcylindrical, widest near base ; 

 surface, as well as that of head, densely and rather finely 

 punctate. Elytra with rows of very coarse, quadrate, deep 

 and closely placed punctures. Length 3.5-6 mm. (Fig. 338.)
