ly, rather closely and unevenly panctate; abdomen almost as wide as the 

 elytra, finely, rather sparsely punciulate. Female unknown. Length 

 6.8 mm.; width 1.0 mm. Nevada (Reno) alticola n. sp. 



5 — Moderately large and stout, piceous-brown, tho elytra notably paler, 



the head black; legs very pale piceous, tho antennae fusco -testaceous; 

 head slightly dilated toward base with the sides broadly arcuate, much 

 longer than wide behind the antennae, the basal angles broadly round- 

 ed; neck fully one-third as wide; antennae and punctuation nearly as 

 In parcua, the latter rather less close-set; prothorax two- fifths io one- 

 half longer than wide, much narrower than the bead, the punctures 

 strong and rather close -set, somewhat sparser posteriorly; sides rather 

 strongly converging and almost straight, the angles obtuse and well 

 rounded; elytra elongate, as long as the prothorax but much wider, 

 somewhat wider than the head, the punctures fine but strong, rather 

 sparsely and evenly distributed without order throughout; abdomen 

 gradually slightly wider from base to apex, the former much narrower 

 than the elytra, the punctulalion fine and inconspicuous, the surface 

 polished as usual; apices of the segments beneath nubilously paler. 

 Female with a long and very slender spine projecting from the middle 

 of the sixth ventral and curving upward behind the end of the abdomen 

 as in parens, except that here the tip of the spine is minutely expanded 

 with the apex of the enlargement truncate, and not aciculate as it is in 

 that species. Length 6.0^ mm.; width 0.85-0.88 mm. British Columbia 



(Victoria),— H. F. Wickham borealis n. sp. 



Much smaller and more slender, parallel, polished throughout, the head 

 paler, the abdomen darker, piceous, the later almost black and not paler 

 at tip, the prothorax, elytra and legs pale rufous, the antennae dusky 

 testaceous; head behind the antennae distinctly elongate, parallel with 

 the sides nearly straight, the angles well rounded as usual; punctures 

 moderately coarse, perforate, close-set laterally, gradually sparser 

 medially, the Impunctate line, rather broad, smaller but deep and sparrer 

 beneath and wanting toward base, the tumescent polished line be- 

 hind the eyes distinct as in the preceding species; antennae only mod- 

 erately stout and dlstally incrassate, much longer than the head ; pro- 

 thorax one-half longer than wide, much narrower than the head, the 

 sides moderately converging and nearly straight, the angles obtuse and 

 rounded; punctures distinct but sparse, very irregularly distributed; 

 elytra small, longer than wide but obviously shorter than the prothorax 

 and slightly wider, not quite as wide as the head, the punctures unusu- 

 ally strong and only moderately sparse; abdomen fully as wide as the 

 elytra, feebly and sparsely punctulaie. Female wanting, the lobe of 

 the sixth ventral In the male much more narrowly rounded than in 

 borealis. Length 4.7 mm.; width 0.68 mm. California (Los Angeles 

 Co.), — H. C. Fall ponionae n. sp. 



6 — Sixth ventral of the male produced at the middle in a rather narrowly 



rounded lobe; pronotal punctures rather coarse and conspicuous 

 though very sparse and almost wholly wanting near the sides toward 

 base. Body very slender, parallel, shining, rufo-piceous in color, the 

 head and most of the pronotum, as well as the abdomen, frequently 

 blackish, the elytra always paler; legs pale, the antennae dusky; head
