104 STBFAMILY IX. OTIORHYNCHINJE. 



second ventral segment equal to or slightly shorter than the third 

 and fourth combined. 



Horn recognized one species, criiuiceus Say, as belonging to 

 the genus. Pierce has recently (1913, 390) combined the genera 

 Phyinatiints and ^'ocJiclcs Lee., and X<niii<-]uts Casey, placing 

 them as subgenera under Panscopus. By erecting two new sub- 

 genera and describing seven new species, he thus brings under 

 Panscopns 13 species, four of which are known from our terri- 

 tory. In addition we herewith describe another species which 

 he does not include in his table. 



KEY TO EASTERN SPECIES OF PAXSCOPUS. 



a. Articular surfaces of the hind tibiae oblique, the corbels open. 

 I). Alternate elytral intervals distinctly elevated; median line of thorax 



strongly impressed on apical half. 



c. First two joints of funicle elongate, the others moniliform; even 

 elytral intervals with a few seta? near apical declivity. 



132. ERIXACEUS. 



cc. All joints of funicle longer than broad; even elytral intervals with- 

 out setae. 133. ALTEKXATUS. 

 6&. Alternate elytral intervals not elevated, all the intervals setose; me- 

 dian line of thorax very feebly impressed along its entire length; 

 elytra ovate, strongly ventricose. 134. MACULOSUS. 

 aa. Articular surfaces of hind tibia? terminal, almost enclosed, the corbels 



cavernous. 



(1. Alternate elytral intervals elevated and setigerous, the even inter- 

 vals without setse; beak longer than head, carinate. 



135. IMPRESSUS. 



del. Alternate elytral intervals not conspicuously elevated, all intervals 

 setigerous; beak not much longer than head, broad, carinate. 



136. CARIXATUS. 



132 (8261). PAXSCOI-US ERIXACEUS Say, 1831, 11; ibid, I, 272. 



Oblong, moderately robust. Body above densely covered with dark 

 brown and pearly or silvery scales, the latter forming a narrow median 

 line on thorax and lateral stripes on its basal half, and a few small scatter- 

 ed irregular pale spots on elytra. Beak one-half longer and as broad as 

 head, indistinctly carinate and with numerous coarse deep seta-bearing 

 punctures; front deeply concave between the eyes, which are subconvex, 

 coarsely faceted; scape reaching almost their middle. Thorax subglobose, 

 at middle one-third wider than long, apex and base truncate, sides broadly 

 rounded; disc convex, its surface without tubercles, the median line dis- 

 tinctly impressed in front of middle. Elytra oblong-oval, base truncate, 

 scarcely as wide as middle of thorax, humeri indistinctly subangulate; disc 

 striate, the strise marked with rather large, distant punctures, each of 

 which is closed by a rounded pearly scale; alternate intervals strongly con- 

 vex and with a row of long inclined setse; even ones flat. Under surface 

 sparsely covered with pearly scales. Length 6 7 mm.
