^ate; margin iilrrowly reflexed. Thorax sliort, broadest at base;, 

 sides broadly rounded, serrate and sparsely ciliate: apex niucli wider 

 tlian the head; anterior augles slightly produced: punctuation evenly 

 distributed, moderately ch)sely placed, rather line; punctures feebly 

 umbilicate. Scntellum sparsely and hnely punctate. Elytra not fim- 

 briate, tinelv, not closely punctate, transversely rugose near the suture 

 and behind the humeral umbones. Pygidiuni transverse, sparsely and 

 finely punctate. ^Sletasternum very densely puiictulate, with long, 

 dense yellow hairs. Abdomen sparsely and obsoletcly puuctulate. 

 Posterior tibia' slender, with very feeble ridges. Claws strongly 

 curved; tooth submedian, small, acute. Last joint of maxillary palpi 

 lusifoi m, not impressed. 



,l/,,/p._Antennal club nearly as long as the stem. Abdomen iiat- 

 tened at middle; penultimate segment with a strong arcuate ridge, 

 distant from apical margin; last segment with a cupuliform, smooth 

 fovea. Fixed spur spatulate, about half as long as the slender exterior 

 spur. The claspers recall those of L. duMa, Smith, l)ut are much 

 smaller and less twisted. 



This species resembles L. errans, but has a ditterent clypeus, much 

 finer punctuation, nouftmbriate elytral margin, slender tibia^ and 

 different sexual characters. (Note on habits, see Schwarz.i) 



Length, about 1<S mm. i rr i ^ 



I have examined four male examples, collected near Alta, Utah, at an 

 elevation of 9,000 to 11,000 feet, by Messrs. E. A. Schwarz and IL G. 

 Hubbard. One has been presented to the National Museum by these 

 gentlemen.
