form of the thorax is quite similar to that of sesostris but it is 

 much more finely and sparsely punctate. 



564 (8904). AMFELOULYPTER SESOSTBIS Lee., 1868, 364. 



Elongate-oval, moderately convex. Pale reddish-brown throughout, 

 strongly shining. Beak rather slender, strongly curved near base, one- 

 half longer than thorax, female, finely striate-punctate. Antennae inserted 

 just behind the middle; second joint of funicle one-half longer than 

 third. Thorax feebly narrowed from base to apical third, then broadly 

 rounded and constricted; disc finely, rather sparsely and unevenly 

 punctate. Elytra slightly wider and twice as long as thorax, less undula- 

 tory than in ater; striae fine, not punctate; intervals wide, flat, minutely 

 alutaceous, their punctures visible but very fine. Under surface except 

 middle of abdomen, densely and rather coarsely punctate. Length 2.7 

 3 mm. (Fig. 95.) 



Jackson and Posey counties, Ind., scarce. May 11 May 20. 



Beaten from wild grapes. Recorded 

 from Michigan, Ohio and Illinois. 

 Riley (1869, 131) called this the 

 "grape-cane gall curculio," stating that 

 it preys upon the canes of the Concord 

 grape, forming in autumn an elongate 

 knot or swelling just above or below 

 a joint. The larva inhabits this gall, 

 pupating within it in June, the adult 

 emerging in two weeks. He bred a 

 species of Chalcis fly from the galls,

 and burning of the infested twigs in winter. 



IX. DESMOGLYPTUS Casey, 1892. (Gr., "chain" -(- "engraved.") 



Closely allied to Psc-udobaris, the prosternum being similarly 

 deeply and abruptly sulcate throughout its length, but differing 

 in elytra 1 sculpture from anything else in the tribe. The opaque 

 surface, deeply impressed and strongly crenulate stride, with nar- 

 row, convex intervals, together with the unusually prominent sub- 

 apical umboues, are unique; while the narrow, subcylindrical 

 form of the body reminds one of Cylindrocopturus. 



565 (8906). DESMOGLYPTUS CRENATUS Lee., 1876, 300. 



Elongate, subcylindrical. Pale reddish-brown, opaque. Beak curved, 

 as long as head and thorax, finely and sparsely punctured. Thorax 

 nearly as long as wide, sides parallel in basal two-thirds, feebly rounded 

 and strongly constricted near tip; disc coarsely and very densely punc-
