THE CANADIAN ENTOMOLOGIST. 153 
[194.] Body black, minutely punctured, hairs white, decunibent ; 
those of the prothorax and elytra looking like minute scales. Head with 
a pair of minute tubercles, not easily discovered, in the space between the 
eyes, anteriorly transversely impressed ; mouth and antennae pale rufous : 
prothorax very thickly and minutely punctured, with a rather obsolete 
longitudinal dorsal ridge : elytra dull-red, with several rows of larger punc- 
tures, the interstices of which are very minutely and thickly punctured, at 
the base rough with minute elevations: legs rufous. |Belongs to Po/y- 
eraphus Er. Taken according to LeConte in “ Alaska, Canada, Maine, 
Louisana.” ( Vide Trans. A. E. Soc., Sept. 1868, p. 169).] 
259. APATE (LEPISOMUS) NIGRICEPS A7rby.—-Length of body x line 
A single specimen taken in Lat. 65°. 
Smaller than the preceding. Body rufous, minutely and thickly 
punctured. Head black, with a very minute tubercle between the eyes ; 
nose impressed ; antennae and underside of the head pale rufous: elytra 
sculptured as in the preceding species, but the rows of punctures are less 
conspicuous. |Synonymous with the preceding, according to LeConte. | 
260. APATE (LEPISOMUS) BREVICORNIS Avzrby.—Length of body 1 
line. A single specimen taken in Lat. 65°. 
Body black, covered with hoary hairs, above resembling scales. An- 
tennae very short with a small knob, rufous: front without a tubercle, 
nose not impressed ; elytra not striated. This species seems to indicate

[x95.| 261. HyLurcus RuFIPENNIS Avrdy.—Length of body 3, lines.

Body dusky, hairy, rather glossy, punctured. Head black, confluently 
punctured ; vertex obsoletely channelled ; antennae rufous: prothorax 
constricted anteriorly, and dusky-rufous ; base with a double slight sinus,

prothorax piceous and paler anteriorly. [Belongs to Dendroctonus Er. 
Taken in Alaska. ‘The punctures of the thorax are not very dense, and 
Qf two sizes intermixed,” —Le Conte. |
