The type is a female, having the fifth ventral strongly, nearly 

 evenly rounded at apex. The elongate prothorax wUh all the 

 angle; broadly rounded is similar to that which Casey declares to be 

 characteristic of the group of species for which he erects the genus 

 Cradytes; the ungual appendages are, however, as long as the claws 

 and attached to them throughout. There is no sign of serrulation 

 of the prothoracic margin, though this may exist in the male. 



None of the characters given by Casey for the establishment of 

 the genus Cradytes are either constant or distinctive and the species 

 must therefore revert to Trichochorus. The present spec.es should 

 stand near these and perhaps closest to rufipenms.

New Mexico, La Cueva, Organ Mts. (5300 ft.), on flowers of 

 FaUugia paradoxa, Sept. (Townsend). Possibly a variety of n.^- 

 penni^, but the narrower thorax with parallel sides and the abund- 

 ant fulvous set^ of the elytra are sufficient to easily distinguish it. 



Triclioeltrous bicoloripes n. sp.-Black, with faint .neous lustre, 

 antenna, piceous, femora black, tibia, and tarsi rufotestaceous; vestiture abund- 

 an but no't dense, almost entirely cinereous in color, giving ^1- '"-t a gra^>sh

 bent hairs, with numerous more erect but only slightly longer hairs interspei.ed 

 throughout; these latter in part blackish at the middle of the pronotal disk, 

 especially a;tenorlv ; fringe of prothorax rather long, fairly even but not dense. 

 An enn J( ^ ) fully reaching the elytral base, rather slender, the outer joints just

 Tnited, oval, pointed. Head polished, feebly wrinkled posteriorly, punctuies
