148 GEO. H. HORN, M. D. 



Male. — Club of antennae longer than the funiele. Abdomen slightly flat- 

 tened, posterior margin of third segment somewhat elevated, fifth and sixth 

 segments longitudinally impressed, the fifth more deeply, the two segments 

 equal in length. Pygidiura convex, si^arsely punctate, tip distinctly truncate. 

 Claws alike on all the tarsi, slender and almost absolutely simple and with 

 merely a feeble trace of erenulation at base under high power. Posterior tibiae 

 fimbriate within with moderately long hairs, spurs slender the outer longer, 

 tarsi distinctly longer at tip. First joint of anterior tarsus distinctly pro- 

 longed at tip. 



Female. — Club shorter than the funiele, ovate. Abdomen convex, sparsely 

 punctured, last two segments with coarser punctures, the fifth with a vague 

 transverse impression in front. Pygidium strongly narrowed to the tip with 

 nearly straight sides, tip truncate, surface sparsely punctured. Claws alike 

 on all the tarsi, each with a moderate sized aeitte tooth at middle and without 

 any evidence of erenulation, except very feebly on the posterior claws. Pos- 

 terior tibiae with a few stiff hairs within, spurs slender as in the male but 

 pellucid at tip, tarsi decidedly shorter than the tibiae. Last ventral segment 

 as long as the preceding. 



This species has nearly the form and appearance of fa Is us, but is 

 rather shorter. ' 



Occurs in Kansas, Colorado and New Mexico. 



Li. seiiex n. sp. — Subeylindrical, brownish piceous, feebly pruinose. Head 

 moderately densely and coarsely punctured, front fiat, suture finely impressed, 

 clypeus transverse, angles broadly rounded, anteriorly feebly emarginate, 

 margin narrowly reflexed. Thorax one- half wider than long, slightly nar- 

 rowed in front, sides broadly arcuate, margin crenulate in front, disc convex, 

 surface with large, moderately deep punctures, sparsely and irregularly placed. 

 Elytra scarcely wider than the thorax, rather coarsely and sparsely punctate, 

 sutural costa feebly distinct. Metasternum with coarse rather sparse punc- 

 tures surface sparsely fimbriate. Abdomen nearly smooth. Length .42 inch; 

 10.5 mm. 



Male. — Unknown. 



Female. — Club of antennae nearly as long as the funiele. Abdomen feebly 

 convex, last segment shorter than the preceding. Pygidium slightly con- 

 vex, impunctured, with scarcely any marginal groove. Claws alike on all 

 the tarsi, each absolutely simple and slender. Posterior tibial spurs rather 

 slender, unequal, slightly pellucid at tip. Tarsi slender one-half longer than 

 the tibiae. 



Even in the absence of the other sex this species may be known 

 by its comparatively, very convex thorax with large punctures dis- 

 tantly placed, deeply impressed and by the metasternum coarsely 

 punctured and sparsely pubescent. On the outer claw of the hind 

 tarsus is a scarcely observable trace of a tubercle which replaces the 

 tooth of the other species. 



One specimen, probably from the Llano Estacado, Texas.
