These three species form a compact group, which must be 

 separated subgenerically, if not generically, from both limbata 

 and tcstacca. The above differences are quite sufficient for 

 mutual separation, but there are a number of others that might 

 be given, such as the relative depths of the transverse basal 

 impression of the pronotum, the form of the scutellum, the 

 prosternal impressed lines, etc. Perpulchra is widely distrib- 

 uted in the Eastern U. S. ; hornii is known to me from both the 

 Sierras and Coast Range of Middle California; Crotch also 

 gives Oregon. 



Alaephus nitidipennis. 



This species, described by the writer in The Canadian Ento- 

 mologist, August, 1905, p. 275, is unquestionably the same 

 as macilentns Csy. The overlooking of Major Casey's de- 

 scription was due to the accidental omission of his species from 

 the Henshaw List. 



The following species recently received is certainly new : 



Alaephus puberulus n. sp. 



Rufotestaceous, elytra slightly paler; head and prothorax densely 

 subrugosely punctate and somewhat dull ; elytra more sparsely and 

 finch- punctate, shining; upper surface clothed with rather sparse but 

 quite conspicuous short erect, pale hair. Antennae slender, half the 

 length of the body, second joint a little longer than wide, fourth 

 shorter than the third and barely three times as long as wide; tenth 

 nearly parallel, eleventh a little shorter than the tenth. Eyes much 

 more prominent than the sides of the front, separated above by a dis- 

 tance subequal to the length of the fourth antennal joint, beneath 

 by a distance one-third greater than the length of the second joint. 

 Prothorax one-fourth wider than long, apex nearly as wide as base, 

 sides broadly, evenly rounded, feebly sinuate before the hind angles, 

 which are sharp and but slightly obtuse ; disk evenly convex, broadly, 

 feebly impressed near the middle of the side margins. Elytra four 

 times as long and nearly twice as wide as the prothorax, humeri 

 moderately prominent, sides nearly parallel and slightly arcuate to 

 beyond the middle, punctures separated by rather more than their 

 own diameters. Prothorax beneath closely punctate, metasternum and 

 abdomen finely sparsely so. Basal joint of hind tarsus evidently 

 shorter than the three following united, second and third joints slender, 

 twice as long as wide or more. Length 6 mm. ; width 2 mm. 



Stockton, Utah.
