large, just visibly narrower than the prothorax, with very prominent 

 eyes; epistoma and basal part of the neck pale; front finely punctate 

 and rugulose; antennae slender, black, the three basal joints testa- 

 ceous; prothorax three-fourths wider than long, general outline 

 and widely reflexed margins nearly as in grandis; surface finely 

 rugose; basal projection and transverse groove distinct; median 

 stria fine, not impressed, terminating near the apex in a small 

 foveiform dilatation; elytra nearly one-half longer than wide, 

 inflatulate behind, fully twice as wide as the prothorax, the trunca- 

 ture broadly and feebly sinuate; striae fine, very finely, subobsoletely 

 micro-punctulate, slightly impressed (cf), scarcely so (9 ); intervals 

 feebly convex to nearly flat; side margins not paler; anterior male 

 tarsi rather thick, with the apex of joints one and two only very 

 slightly oblique. Length 7.2-7.6 mm.; width 3.0-3.35 mm. New 

 Mexico (Santa Fe), Utah (Ureka) and Mexico (Tepehuanes, 



Durango). Three examples atriceps Lee. 



Body very nearly as in atriceps but much smaller in size, the coloration 

 and rather shining lustre as in that species, but with the tibiae pale, 

 the tarsi piceous, the neck black throughout; head not so large, 

 evidently narrower than the prothorax, otherwise similar, the 

 antennae similar in coloration, but rather more slender and with the 

 individual joints notably shorter; prothorax similar, but widest 

 more evidently before the middle and with the sides less widely 

 and more gradually reflexed except at base; basal parts similar, 

 the surface finely rugulose, the median stria nearly similar but 

 feebly impressed, not at all enlarged subapically and entire, attaining 

 the apical margin; elytra two-fifths longer than wide, feebly inflated 

 behind, twice as wide as the prothorax, nearly similar at tip; striae 

 fine, feebly but evidently micro-punctulate, the intervals nearly flat. 

 Length 5.7-6.0 mm.; width 2.5-2.'"6 mm. Colorado (Boulder Co.). 



nanulina n. sp. 



The three species enormis, pimaUs and tuckeri are evidently 

 allied to pleuritica Lee, from Lake Superior, which was placed in 

 typical Lehia by Horn, who however at the same time alluded to 

 its strongly suggestive resemblance to Loxopeza. It seems to me 

 that all four of these species should be allied more closely to Loxopeza 

 than to Lehia, notwithstanding the fact that the peculiar anterior 

 male tarsal characters distinguishing Loxopeza have become virtu- 

 ally obsolete. The case is similar to that of Colpodes in the Batesian 

 sense, Mr. Bates, as well as Chaudoir, having assigned many 

 species to Colpodes, in which the peculiar tarsal characters of the 

 latter genus have become very nearly extinct. The species defined 

 above as enormis was sent to me under the name pleuritica Lee, 

 but it differs from the latter, judging by the author's description, 

 in having no vestige of the pale elytral margins, apparently exactly
