be conveniently arranged in six subgenera. By the formerly accepted 



method of arrangement we would be compelled to have seven genera 



for eleven species. Such a system would soon lead to nothing but 



chaos. 



Subgenus NOCHELES Horn. 

 Nocheles Horx. 



This subgenus is adequately defined in the table preceding. The 

 type is torpidus LeConte. 



PANSCOPUS (NOCHELES) TORPEDUS LeConte. 

 Nocheles txxrpidus (LeConte) Horn. 



This species is especially remarkable for the loss of the thh^d or 

 fourth ventral segment in the female, which is also much more robust 

 than the male. Six specimens of each sex are at hand from Olympia, 

 Washington, and Portland, Oregon. The material from Alta, Utah, 

 formerly referred here is probably ahruptus Casey. 



Subgenus PHYMATINTJS LeConte. 



Phymatinus LeConte. 



This subgenus is adequately defined m the table preceding. The 

 type is gemmatus LeConte. 



PANSCOPUS (PHYMATINUS) GEMMATUS LeConte. 

 Phymatinus gemmatus LeConte. 



This is the most beautiful species in the genus and by its assem- 

 blage of characters might be thought to merit generic rank. On close 

 inspection it is found to possess only one character, its tuberculation, 

 which radically separates it from all the other species, except the 

 following. 



PANSCOPUS (PHYMATINUS) SULCIROSTRIS, new species. 



This very extraordinary species is described from a single specimen 

 collected at Oak Pomt, Washington, April 30, 1910, by M. A. Yothers 

 (Wash. Exp. Sta. No. 5). In coloration it resembles certain species 

 of European Otiorhynchus but in structure it is a near relative of 

 P. gemmatus LeConte. 



Length 9.5 mm.; width 4 mm. Color deep black, tarsi piceous; 

 vestiture of very sparse golden scales, arranged in patterns; surface 

 extremely tuberculate. 



Head smooth to a transverse depression between the posterior 

 portions of the eyes, with a few scales set in shallow punctures. From 

 this transverse depression the front and beak are very roughly rugose 

 and punctate. The deep narrow frontal sulcus on the beak becomes 

 broader and deeper but again narrows toward the tip and becomes a 

 finely sulcate carina which divides to form the nasal plate; the sulcus 

 is finely and sparsely squamose. The borders of the sulcus are 

 sparsely punctured carinae. The sides of the beak are deeply and 

 densel}' rugosely punctate. The space in front of the insertion of the
