sparse, interspaces rugulose; disc of elytra shining, nearly glab- 

 rous, pubescence more abundant at sides. Declivity shallowly but 

 widely sulcate, sulcus shining; suture moderately wide and ele- 

 vated, with a sparse series of rather coarse, blunt, tooth-like 

 granules ; lateral elevations each with a row of five or six similar 

 granules on the third interspace, becoming larger posteriorly, each 

 with a short stiff hair, with a few small granules lateral to it near 

 the apex. 



Male with body of similar size and proportions; front flattened 

 on a semicircular area, with a distinct median carina produced to 

 form a distinct, laterally compressed tooth one-third of the dis- 

 tance above the epistomal margin ; slightly excavated at each side, 

 rather coarsely and roughly punctured, pubescence inconspicuous ; 

 pronotum more broadly rounded in front ; elytra more narrowly 

 rounded behind ; declivital armature not so coarse as in the female 

 but similar. 



Type— A female, Orono, Maine, Aug. 1, 1919, M. W. Blackman, 

 collector ; Lot No. M-122-a. 



Host plant — Picea ruhens Sarg. 



This species is in some respects ratlun- close to P. 2^ !(/(•/( e//i/.< 

 Eichh. {hirticeps Lee.) and is very similar in general appearance. 

 It may, however, be readily distinguished by the more nari-owly 

 rounded anterior margin of the pronotum, the more broadly 

 rounded apex of the elytra, the lesser elevation of the suture on the 

 declivity, but especially by the presence of the carina on tbe front 

 of the head* in both sexes and by the strongly developed frontal 

 tooth in the male. It has been compared with LeConte's types of 

 hirticeps and pusio both of which are believed to be synonyms of 

 piUchellus and is distinctly different although closely allied. 



This species is described from a series of eighteen specimens 

 taken from their burrows in the bark of a small spruce about six 

 feet high which had been cut the preceding spring. The burrows 

 are started near the base of a smaller branch and are of the radiate 

 type with longitudinal and diagonal egg galleries. Only the one 

 lot of specimens was found in Maine. Additional specimens were 

 also taken from red spruce June 15 and 28, 1921, at Cranberry 

 Lake, N. Y., by Blackman and Fivaz. 



Cryphalus ma'inensis n. sp. 



Description of the adult female: Black; 1.63 mm. long, 2.23 

 times as long as wide. 



Front of the head convex, shallowly, transversely impressed 

 between the eyes; surface sub-opaque, closely and roughly but 

 not coarsely punctured, with a few fine short hairs; epistomal 

 margin with a few short hairs, slightly emarginate and feebly 

 elevated in the median line. Eyes finely granulate, the anterior 

 line weakly emarginate. Antenna lighter in color; club twice as 

 long as funicle, apparently with four sutures, of which all but 

 the distal one (which is the least distinct) are nearly straight.
