Rather stout, parallel species, having the head broadly sinuate- 

 truncate at base; third joint of maxillary palpi elongate-oval; an- 

 tennae slender, reaching beyond middle of thorax; neck two-fifths 

 as wide as head ; thorax subquadrate, the apex somewhat produced 

 forward at middle. One species occurs throughout the Eastern 

 United States. 



823 (2559). Aderocharis corticina Grav., Mon. Col. Micr., 1806, 184. 

 Rather broad, moderately convex. Dark reddish-brown, the entire up- 

 per surface minutely and densely punctate; antenna? and legs paler; head 

 blackish. Head a little wider than long, its sides feebly curved. Thorax 

 slightly wider than long, a little narrower than head, sides straight, feebly 

 converging from the distinct apical to the broadly rounded basal angles. 

 Median smooth line very narrow. Elytra together quadrate, a little longer 

 and wider than thorax. Abdomen slightly narrower than elytra ; the sixth 

 ventral of male broadly and shallowly emarginate. Length 6-7 mm. 



Marion and Monroe counties; rare. June 9-June 12. Taken by 

 sifting decaying maple logs. Described by Say from Posey County 

 under the name Lathrobium millepunc tai um. 



XLVII. Sciocharis Arrib. 1884. 



Small, rather stout brown or piceous species having the two 

 basal joints of antenna? much thickened, the second in our species 

 longer than third; gular sutures but slightly separated, closest to- 

 gether at base ; neck less than half as wide as head ; front tarsi more 

 or less dilated ; basal joint of hind tarsi distinctly longer than sec- 

 ond, joints two to four decreasing in length. One of the three 

 United States species occurs in Indiana.

 smooth median line. Elytra one-third longer, slightly wider and a little 

 more coarsely and sparsely punctate than thorax. Abdomen as wide as 

 elytra, minutely and rather closely punctate. Sixth ventral of male with
