than the thorax, shorter than the abdomen, attenuate or parallel and trun- 

 cate, lateral margins and usually tips strongly serrate. Legs long and 

 thin, tarsi with five segments, the first covered by the second from above, 

 segments two, three and four bearing lamellse beneath, ungues long and 

 thin, simple. Type species : Hydnocera curtipennis Newman. 



To this genus are to be assigned the following species : /. curtipennis New- 

 man (longicolUs Ziegl.) , tabida Lee, schusteri Lee, ornata Wolc, gerhardi 

 Wolc, pusilla Schaeff., cegra Newm., brunnea sp. nov., and albocincta 

 Horn. 



Isohydnocera brunnea sp. nov. Very elongate, form of agra Newm. 

 Brown, eyes black. Head sparsely and finely punctured, the punctures on 

 the vertex being connected by fine grooves, surface otherwise smooth, 

 very sparsely pubescent. Thorax much longer than wide (ratio of length 

 to breadth is 40-32), apical transverse impression wide and shallow, basal 

 deeper, section of thorax between impressions subglobose, lateral fovese 

 deep and distinct but small, surface except for a few punctures smooth, 

 very slightly alutaceous toward hind angles. Scutellum brown, sparsely 

 pubescent. Elytra elongate, suture nearly closed, apices very sharply trun- 

 cate and tumid, lateral margins serrate, surface moderately densely and 

 coarsely punctured, the punctures becoming more coarse toward apex, 

 although nearly obsolete on the tumid portion of the tips. Pubescence 

 sparse, erect and pale. Underparts brown, posterior halves of meso- and 

 metapleurse densely pubescent with pale hairs. Legs long and slender, the 

 posterior tibise somewhat arcuate, brown. Length 4.8 mm. 



Type locality : Riley Co., Kansas. Type in the collection of 

 Kansas Agricultural College. This species is closely allied to 

 cogra Newm. but is separated from that species by the nearly 

 smooth thorax and by the different thoracic ratio. The thorax 

 in cegra Newm. is finally alutaceous all over and has a ratio of 



32 = 25. 



Wolcottia gen. nov. Body elongate, slightly attenuate posteriorly. Head 

 short, front flat, lateral margins slightly concave to accommodate eyes, which 

 are not prominent, finely granulate and minutely emarginate as in Isohyd- 

 nocera. Labrum broad, entire. Mandibles falciform, with a small inter- 

 nal tooth near apex. Terminal segment of maxillary palpi conical, as 

 long or slightly lotiger than the preceding, that of the labial palpi very 

 large, triangular. Antennae short and stout, ii-segmented; first segment 

 slightly longer than broad, second nearly spherical, third to eighth as long 

 as broad, trapezoidal, becoming progressively broader, ninth broader than 

 long, nearly as wide as tenth, tenth and eleventh forming an oval mass 

 nearly as long as the three preceding segments. Thorax slightly broader 

 than long, sides feebly dilated, slightly narrower than the head with eyes. 

 Elytra at humeri broader than the head across eyes, attenuate poste-
