761 



A. posticus Melsh., length 12 mm., and A. rufifrons Rand., tho- 

 rax reddish with black center, elytra brownish with paler sides, 

 length 15 mm., have both been recorded from near Cincinnati. 



XXXVI. Leptoschema Horn. 1885. (Gr.. " slender + form. " ) 



Differs from Athoiis only in having the prosternal sutures 

 double. The antenna? are as long as head and thorax : first joint of 

 hind tarsi much longer than second, the joints not lobed beneath. 

 Three species are listed from the United States, two of which have 

 been taken in Indiana. 



1447 (4409). Leptoschema bicolob Lee. Trans. Amer. Phil. Soc. X. 1S53. 

 428. 



Elongate-oblong, broadest behind the middle. Above black or dark 

 reddish-brown, sparsely clothed with short, suberect. grayish-yellow pubes- 

 cence: beneath uniform pale reddish-brown. Clypeus of female obtusely 

 rounded in front, impressed above. Antenna? with second and third joints 

 each nearly as long as fourth : this and the following joints without promi- 

 nent angles in either sex. Thorax one-third longer than wide, strongly 

 convex, sides feebly rounded, disk finely, evenly and densely punctured; 

 hind angles slightly diverging, strongly carinate. Elytra] striae fine, the 

 punctures small, close-set : intervals flat, rather densely and roughly punc- 

 tulate. Length 8.5-12 mm. 



Putnam County; rare. August 12. A single female taken 

 from beneath the bark of a maple log. It is more robust, less shin- 

 ing and more densely punctured beneath than the single male type 

 in the Cambridge collection. 



144S (4410). Leptoschema discalceatem Say. Trans. Amer. Phil. Soc. 

 AT. 1836. 169: ibid. II. 604. 



Elongate, rather slender. Reddish or pale chestnut-brown, very sparse- 

 ly clothed with fine yellowish pubescence: beneath pale, dull brownish-yel- 

 low. Clypeus prominent, subtmncate. Second and third joints of antenna? 

 shorter than in bwolor. the outer joints broader, with the angles better de- 

 fined, thus causing them to appear more serrate. Thorax slightly longer 

 than broad, sides broadly rounded on apical half: disk more sparsely, 

 coarsely and unevenly punctured than in bicolorj hind angles slightly di- 

 varicate, strongly and obliquely carinate. Elytra with sides parallel to 

 apical fourth, thence converging to a broadly rounded apex; stria? finely 

 punctate ; intervals subconvex. sparsely punctulate. Length 11.5-13 mm. 



Laporte and Fulton counties: rare. May 26- August 3. Taken 

 from beneath bark of dead tamarack and pine. 



XXXYII. Bladus Lee. 1861. 



Front not margined behind the labium : tarsi not lobed beneath ; 

 prosternum not lobed in front, the sutures straight and excavated 

 hi front. But one species is known and was described from Indiana.
