New Species of Pogonocherus, with Synoptic Table. 



By H. C. FALL. 



Four species of this genus ncgnndo, arizonicns, ciilifor- 

 nicus and alaskaus have been more or less recently describ- 

 ed by Mr. Schaeffer. Three more are made known in the 

 present paper bringing the number of known form- within 

 our faunal limits up to twelve. As only the live of tin- 1 I en 

 sha\v List were known when Lcng and Hamilton presented the 

 last synoptic table (Trans. Am. Knt. Soc. iS</.. \>. 1351 a ni 

 table is herewith appended. 



P. obscurus n. sp. 



Moderately stout, black, clothed n< 'isely \vitli ap]>r<--- 



blackish and ashy grey hairs, the latter pred< miinai 'ly in a 



slightly antcmedian discal area which extend- forward laterally to the 

 humeri ; the elytra with four scries of small black urn-, of short < 

 hairs, the inner series close to the suture, the thr<-<- outer ones occupy- 

 ing the positions of the costae, which, 1 reel] 

 evident in this species. Entire body above, antenna'-. I.--, and -id<-- 

 of abdomen clothed with long flying hairs, which an- for the IT 

 blackish on the upper surface and pale beneath. Antennae one-third 

 longer than the body in the male, slightly longer than the body in tin- 

 female, the longer joints in great part pale, tl Macl- 

 apical half; scape more than four times as lou.y as wide. rax 

 about as long as wide, lateral tubercles obtuse, discal ones modi 

 Legs black, the tibiae variegated with pale hairs. Last ventral segment 

 rounded at apex in the male, truncate with the apex beveled or "M .iuel\ 

 ascending in the female. Length 7-9 mm.; width 2.6-^.4 mm. 



Described from 2 $ 's and i $ kindly given me i>y 

 Schwarz. who took them at Bright Angel, Arizona. 



This species is rather closely allied to itc^iindo. but i- read 

 ily separated by the tabular character- It is perha]>- even 

 closer to calif or nicus, but as this latter is compared by its 

 scriber with oregonus, 1 have so associated it in the f 

 table. There is before me a specimen taken by Dr. 

 in the San Bernardino Mountains of California. 

 with some confidence to calif ornicus. It is very near 

 rns, but the long hairs are shorter and les 

 out, and all those arising from the antennae are 

 in obscnrus they are brown and white, the bro pre 



nating.
