THE SILKEN FUNGUS BEETLES. 575 



connected by a deep channel along the basal margin. Two species 

 are listed by Casey, one of which occnrs in Indiana. 



1093 ( ). Crosimis hietus Casey, Joui-ii. N. Y. Ent Soc, VIII, 1900, 90. 



Broadly oval. Piceous or black ; legs and antennfe somewhat paler ; 

 elytra dark red, lilaek at apex, on middle of side margins and transversely 

 behind the base near the suture. Thorax nearly twice as wide as long, the 

 sides feebly converging from base to apex, not continuing those of the ely- 

 tra ; surface finely, deeply and densely punctate, the submarginal line 

 parallel to the edge. Elytra with long, rather dense pubescence and with 

 long, erect hairs in addition ; surface irregularly, sparsely and rather 

 i-iiarsely punctate. Length 1.. 5-1.8 mm. 



Putnam and I'osey counties; scarce. April G-Apj-il 25. Taken 

 from a large yellow well-decayed fiesliy fungus, and by sifting. 

 Known from Ohio and Iowa. 



VIII. Cbyptopiiagus Hbst. 1792. (Gr., "iTyptiioam ! etiting.") 



This genus comprises numerous oblong or oblong-oval species, 

 distinctly though not densely pubescent, having the thorax trans- 

 verse and bearing a short tooth on each edge near the middle, the 

 apical angles thickened and base with two small foveas or pits con- 

 nected by a fine groove ; front not margined. Casey lists 32 species 

 of the genus, 25 of Avhich he describes as new. Of these five have 

 been taken in Indiana, while one or two others doubtless occur. 



KEY TO INDIANA SPECIES OP CBYPTOPHAGUS. 



a. Sides of the thorax distinctly angulate at about the middle, the spicule 

 or little point at apex of the angle therefore more prominent and 

 separated from the thickened node of front angle by a rounded notch. 



1094. ACUTANGULCS. 



aa. Sides of thorax broadly and evenly curved from base to apex, the spicule 

 near middle very small and Indistinct. 

 6. Disk of thorax with four more or less evident smooth elevations and 

 a short elevated ridge at middle of base, 

 c. Thickened portion of front angles of thorax with a broadly oval, 

 sharply defined flat or feebly concave disk, having a large cen- 

 tral puncture. 

 d. Dark reddish-brown; disks of front angles of thorax large, as 

 long as the distance thence to the median spicule. 



1095. CROCEUS. 



dd. Pale br<iwnish-yellow ; disks of front angles smaller, distinctly 

 shorter than distance thence to the spicules. 



1090. ij\ti(Tv\vxjs. 

 cc. Tl]icl«'iied portion of front angles of thorax small, irregular, nar- 

 row and without a puncture-bearing disl;;. 

 r. AntenniK long, rather stout, about half as long as body; length 



1.8 mm. ANTENNATUS.
