spaces nearly flat, finely rugulose. Beneath densely puuctulate and pubescent. 

 Length 2.7-3 mm. 



Texas, Bosque County — Belfrage. 



A small stout species with very convex prothorax, which, unlike 

 all the other small eyed species, is not at all flattened at sides, the 

 margin very narrow. The pubescence is denser than in any other 

 of the allied forms, except gracilipes, which is more elongate and 

 otherwise very different as indicated in the table. 



8. X. lugubris Lee. — Allied to fucatus, but smaller and more elongate. 

 The antennae are subpectinate in the male, acutely serrate in the female, the 

 intermediate joints in this sex being about as strongly transverse as in the male 

 of fucatus. The sides of the thorax are a little less flattened and somewhat less 

 strongly rounded than in fucatus; sculpture and vestiture nearly as in the latter 

 species. The line of erect hairs on the first two ventral segments in the male is 

 peculiar to this species. The color is black in all specimens seen. Length 2.5-3 mm.

 Nebraska (LeConte collection). 



9. X. gracilipes n. sp. — Elongate-oval, black ; finely subrugosely punc- 

 tured and dull; pubescence cinereous, dense. Antennae subpectinate, nearly as 

 in lugubris and in Vrilletta convexa. Terminal joints of palpi not compressed, very 

 slender and elongate, acicular. Eyes small, not prominent, vertex obscurely 

 subcarinate. Prothorax strongly transverse, side margin moderately reflexed. 

 Tarsi very slender slightly compressed, first joint subequal in length to the two 

 following; second three-fourths as long as the first, third and fourth very short, 

 together shorter than the second ; fifth very elongate, subequal to the second and 

 about five times as long as wide. Length 3.6 mm. 



Described from a single example from Wyoming, submitted by 

 Mr. Schaeffer. The facies of this species is in every respect that of 

 typical Xijletinux, and it is therefore placed here for the present, 

 notwithstanding the anomalous palpal and tarsal formation, which 

 would perhaps warrant its separation as a distinct genus. 



LASIODERMA Stephens. 



Form oval, more or less elongate, moderately convex, pubescence 

 moderate, subrecumbent. Terminal joints of palpi elongate, subpar- 

 allel, the apex obliquely truncate. Antennae serrate, but less 

 strongly so than in Xyletinus, the outer joints not more elongate. 

 Head rather large, deeply excavated beneath, with a posterior medi- 

 angular prominence ; eyes small ; epistomal suture arcuate, scarcely 

 impressed. Prothorax evenly, strongly convex, front angles acute,
