" Oval, convex, black, shining. Head and thorax sparsely 

 and finely punctulatc. 'J'horax with an entire, well- 

 impressed, submari^inal stria. Elytra more sparsely and 

 linely punctured tiian the thorax^ surface with six entire 

 dorsal and a sutural stria, all sharply impressed, the inner 

 dorsal and sutural joining- in an arc ; external subliumeral 

 entire, internal absent. Epipleuraj unistriate. Propy<^idiuin 

 and pygidium sparsely and finely punctured. Prosternum 

 convex, the strise distinct, diverging, and ascending in front. 

 ]\Iarginal stria of" the mesosternum entire. Body beneath 

 sparsely punctulatc. Anterior tibias very finely serrulate. 

 Length '10 inch; 2'5 millim. 



" It is not without some little doubt that I refer this species 

 to Phelisler. The antennal fossas are slightly enclosed in 

 front, approaching Onlhophilus, but the resemblance extends 

 no further. It might be placed near //. vernusj from which, 

 however, it differs in many points. 



" llah. Arizona ( //. K, Morrison) ." 



Horn does not say whether the mesosternum is projecting 

 or bisinuous, one of the essential characters of Pkelister. 

 The inner humeral stria is apparently complete.
