flowers of Cratctgiis, and later on foliage of various plants. Noted 

 as mating on April 26. 



1400 (4293). Agriotes avulsus Lee, Trans. Amer. Phil. See, X, 1S53, 457. 



Elongate-oblong ; convex. Piceous-black, shining ; sparsely clothed with 

 yellowish pubescence ; legs and antennae pale reddish-brown. Thorax slightly 

 longer than wide, sides rounded on apical third ; hind angles feebly diverg- 

 ing, strongly carinate ; surface rather sparsely and very coarsely punctate. 

 Elytra 1 striae rather coarsely punctate ; intervals nearly flat, sparsely and 

 roughly punctulate. Length 8 mm. 



Vigo County; scarce. May 24-June 9. Beaten from foliage. 

 Known heretofore only from New England and Pennsylvania. 

 Resembles pubescens but readily distinguished by the form of hind 

 coxal plates, more shining surface and more coarsely punctured 

 thorax. 



XXXI. Doloptus Esch. 1829. (Gr., "crafty.") 



Differs from Agriotes only in having the side margin of the 

 thorax straight instead of being bent downward in front. One 

 species only is known from North America. 



1401 (4207). Dolopius lateralis Esch., Thon. Archiv., But. II, 1S29, 34. 



Elongate, slender, subconvex. Piceous or sooty brown, sparsely clothed 

 with short yellowish pubescence; apex and hind angles of thorax, more or 

 less distinct subhumeral stripe of elytra, legs and basal joints of antennas, 

 yellowish. Thorax slightly longer than wide, sides parallel, rounded on 

 apical fourth ; hind angles acute, prominent, not divergent ; disk densely 

 and rather finely punctate, and with a faint median impressed line on 

 basal half. Elytra! stria? with distinct, close-set punctures; intervals flat, 

 finely, densely and rugosely punctulate. Length 7-8 mm. 



Northern half of State ; frequent. April 15-October 12. Beaten 

 from foliage, especially that of tamarack; often occurs on flowers 

 of blackberry. In some specimens the yellow on elytra is reduced 

 to a mere trace on humeral angles. 



XXXII. Glyphonyx Cand. 1863. (Gr., "carve + claw. ") 



Small, slender, brownish beetles, attenuate behind the middle 

 and having the clypeus more or less angulate ; hind angles of tho- 

 rax not carinate; third and fourth joints of tarsi slightly lotted 

 beneath. Five species are known from the United States, four of 

 which occur in Indiana.
