nyx. In this species as in A. inermis, subvittatus, and pauperculus, the 

 pygiclium is entirely covered by the elytra, and the fifth ventral is longer 

 than in the other species. In a revision of this group they may indicate a 

 distinct genus. 



Division C. Funiculus of antennae 6-jointed. 



32. A. crataegi Walsh, Proc. Ent. Soc. Phila. vi, 266. 

 Middle, Western, and Southern States, to Texas. 



An elongate uniformly ferruginous species, with dull lustre, and pubescent 

 with yellowish hairs, which are condensed on the median line of the pro- 

 thorax forming a dorsal vitta. The beak is punctured, and the front chan- 

 neled; the prothorax densely punctured; the elytra deeply striate, with the 

 interspaces convex. The funiculus of the antennae is 6-jointed, and slender, 

 second joint a little longer than third; thighs armed with an acute tooth; 

 front tibiae nearly straight. The size and form is as in A. sycophanta, and 

 like that species, it is parasitic in galls ; in this instance, however, upon 

 Crataegus, and in the other upon Salix. Length 2.3 mm.; .09 inch. 



33. A. subfasciatus, n. sp. 



Reddish-brown, rather robust, finely and thinly pubescent ; beak opaque, 

 not distinctly punctured; prothorax strongly punctured, elytra with the 

 striae coarsely punctured, interspaces nearly smooth; behind the middle is 

 a broad transverse denuded band, at the margins of which the pubescence 

 is more condensed. Antennae more robust than in the preceding, funiculus 

 6-jointed, second joint not longer than the third. Thighs with a small acute 

 tooth. Length 1.5 mm.; .06 inch. 



One specimen, New York. Greatly resembles what I have above con- 

 sidered as A. musculus, but is much smaller, and differs by the 6-jointed 

 funiculus of the antennae. 



34. A. robustulus, n. sp. 



Robust, black, clothed with ashy scales. Beak punctured and feebly 

 striate. Prothorax much wider than long, narrowed in front, rounded on 

 the sides, closely and deeply punctured. Elytra one-third wider than the 

 prothorax, striae coarsely punctured towards the base, interspaces flat. 

 Antennae and feet brown, ihighs not toothed, funiculus 6-jointed, second 

 and third joints equal, or nearly so. Length 1.5 mm.; .06 inch. 



Kansas; three specimens. 



35. A. nubilus, n. sp. 



Rusty brown, rather elongate, sparsely and finely pubescent, with inter- 

 mixed scattered pale-yellowish scales. Beak finely punctured, obsoletely 

 striate, frontal fovea feeble. Prothorax wider than long, narrowed in front 

 and rounded on the sides, strongly punctured, with a short whitish dorsal 

 line behind the middle. Elytra with the striffi very coarsely punctured, 

 interspaces slightly rugose; the scales are irregularly scattered, so as to 

 give the appearance of a large denuded dorsal space, and a posterior denuded 

 band oblique inwards and backwards. Antennae with the funiculus stout,
