858 FAMILY XLII. — CLERID.T2. 



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

 the antennal club are much prolonged. Ten genera are represented 

 in America north of Mexico, six of which are known from Indiana, 

 while another may occur. 



KEY TO INDIANA GENERA OF ENOPLIINI. 



a. Three outer joints of antennas very large, flat, dilated; six segments of 

 abdomen visible. 

 6. Eyes emarginate on inner side ; antennae 10-jointed. 



c. Last joint of both pair of palpi elongate-triangular ; eyes broadly 



emarginate. IX. PHYLLOBaiNUS. 



cc. Last joint of labial palpi obconic; last joint of maxillaries sub- 

 cylindrical, truncate at apex ; eyes narrowly but deeply emargi- 

 nate ; body very elongate. Elupotoma. 

 66. Byes emarginate in front. 



d. Basal joint of tarsi not smaller than second, visible from above, 

 e. Antennae 11-jointed, joints 2 to 8 distinct. 



f. Sides of thorax rounded, not constricted before the base ; form 

 rather broad, resembling that of certain fireflies. 



X. Chabiessa. 

 ff. Sides of thorax sinuate, angulately enlarged behind the mid- 

 dle, constricted before the base. XI. Ceegta. 

 ee. Antennae 10-jointed, joints 2 to 8 indistinct. XII. Ptticera. 

 dd. Basal joint of tarsi small and short, covered by the second ; black, 

 thorax yellow. XIII. Orthopi.eura. 

 aa. Three outer joints of antennae forming a small compact club ; five seg- 

 ments of abdomen visible. XIV. Neorobia. 



IX. Phtllob^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 ; antemiaj 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.

 Elongate, subeylindrical. 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- 

 1< .\Y subapical spot. Thorax subeylindrical, widest near base ; 

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

 -=--.-.- •— punctate. Elytra with rows of very coarse, quadi'ate, deep 

 tungmai.j ^^^ ^j^g^jy pj^^^^^ punctures. Length 3.5-6 mm. (Fig 338 )
