THE CANADIAN ENTOMOLOGIST. 221 



The antennal scape is slightly widened distally, and narrowed at the 

 tip ; the first segment of the funicle is very large, wider than long ; the 

 remaining four segments of the funicle are very short, the 4lh and 5th 

 wider ; club 3-segmented, much longer than the funicle, long, suboval, 

 distally ])ointed, narrower than in frontalis^ with the lateral dilations of 

 the segments less elongate. 



Hind tibicC stout, much widened distally ; outer margin slightly 

 curved, broadly rounded distally ; inner margin also distinctly curved, 

 with a slender mucro at the tip ; outer margin with one submarginal 

 spine, and the distal margin with six submarginal spines and marginal 

 tubercles, clothed with long, slender, plumose hairs. The outer margin is 

 not so strongly curved as in Fhloeotribus, and not straight with a truncate 

 distal margin as in Phlonophthorus (see Eichnoff). 



Ste. Anne de Bellevue, P. Q., Canada. In dead but green branches 

 of Picea canade?isis. Two broods annually. 



This species differs from limifiaris and frontalis in its smaller size, 

 more elongate form, elytral sculpture as given above, and characters of 

 antennie and tibiae. I have not seen P. ptiheriihis Lee, but judging from 

 his description, which is quoted below, this species is smaller and differs 

 in its more strongly elevated and very strongly serrated elytral interspaces. 



^'' Phlixotribus piiberuliis Lee. — (Bui. U. S. Geol. and Geog. Survey 

 of Territories, Vol. V., 1880.) Cylindrical, black, nearly opaque, clothed 

 with fine, erect, yellowish pubescence ; base of antennae and tarsi piceous. 

 Head sparsely, finely punctured ; front nearly smooth, shining, broadly 

 concave, with two small acute cusps on the epistoma. Prothorax wider 

 than long, sides oblique, slightly rounded, coarsely punctured, dorsal line 

 obsolete, visible only near the middle. Elytra with shallow striae formed 

 of quadrate punctures ; interspaces somewhat elevated, not wider than the 

 striae, with the hair arranged in rows. Length, 2.5 mm. 



" Veta Pass, one specimen. This species resembles in appearance 

 Hylesinus opaculus, but is quite different in characters. The joints of 

 antennae are less prolonged than in the other species, so that the club 

 becomes elongate oval, and as long as the remaining joints united " 



I have described this species as belonging to Phloeotribus, but it 

 might quite as well go in PJilceophthonis. Mr. Eichnoff characterized 

 Phlceophthoriis Woll. and Phlceotribus Lat. as follows : 



" Phlodophthorus Woll. — Antenna with a 5-segmented funicle and a 

 3-segmented long, pointed club, with the segments feebly widened on the
