TRIBE IX. OTIDOCEPIIALINI.

near its base, very remote in single rows on the elytra; scutellum and 

 sternal side pieces densely white pubescent. Beak coarsely punctate and 

 rugose on sides, feebly sulcate above between the antennas. Head very con- 

 vex, sparsely and finely punctate. Thorax but slightly longer than wide at 

 middle, strongly narrowed toward base, very minutely and remotely punc- 

 tate. Elytra twice as long, and, behind the middle, nearly twice as wide 

 as thorax; disc with rows of fine, rather distant punctures. Length 3.3 

 4.3 mm. 



Abundant near New York City on hickory., May to July. 

 Ranges from Fall River, Mass., and Litchfield, Conn. (June 14), 

 to Ohio and southward to Texas. Riley states that it has been 

 bred from Cynipid galls on oak. Easily known by the large, 

 prominent, approximate eyes and fine, unimpressed punctures of 

 the elytral rows. 



365 (8607). OTIDOCEPHALUS CHEVROLATII Horn, 1873, 450. 



Subcylindrical, strongly convex. Black, polished, almost glabrous 

 above; scutellum and a narrow line along sides of 

 lower surface with dense white hairs. Beak short, 

 polished, the sides with two coarsely punctured sul- 

 ci. Thorax about one-third longer than wide, the 

 apical two-thirds strongly convex, basal third nar- 

 rowed; disc sparsely and very coarsely punctured, 

 more densely toward apex. Elytra less than twice 

 as long as wide, broadly oval, very convex; disc 

 with rows of very fine, rather close-set punctures, 

 those on the sides impressed. Femora with a min- 

 ute acute tooth; tibise almost straight. Length 

 3.74.5 mm. (Fig. 70.) 



Frequent throughout the northern half 

 of Indiana; less so southward; May 21- 



I ig 'f, 7 ont ^vie b w et jf head' June 1 ^ ' beaten from oak. Abundant near 

 (Original.) New York City on elm, hickory, grape, hazel 



and other plants, June and July. Ranges from New England and 

 Quebec to Iowa, Georgia and Texas. Pierce (1916) states that 

 it breeds in galls of Atupliibolips on live oak trees in Texas. 

 Readily known by the large frontal fovea, wide, strongly inflated 

 elytra and almost glabrous upper surface. This is the 0. myrme- 

 codcs of Chevrolat, which name Avas preoccupied.

Black, shining, bristling with long, coarse, erect, blackish setae, with 

 a few short, paler, subrecumbent hairs interspersed. Head and beak 

 coarsely, closely and unevenly punctate; beak not quite as long as thorax, 

 rugosely striate on the sides. Thorax obovate, base strongly narrowed;
