the next two or three joiats perceptibly elongate, thence distinctly 

 transverse to the tenth, the eleventh large, oglvally pointed at tip, longer 

 than the two preceding combined and evidently stouter; prothorax 

 nearly a third wider than the head and a fifth wider than long, widest 

 near apical third, the sides feebly converging thence basally and broadly 

 arcuate to the apex, the surface with a large oval concavity in basal 

 half and median third ; elytra transverse, slightly wider and evidently 

 shorter than the prothorax, subparallel, the humeri slightly exposed at 

 base; abdomen parallel, rather wider than the elytra; legs long, the 

 hind tarsi about three-fourths as long as the tibiae. Length 2.9 mm.; 

 width 0.8 mm. British Columbia (Gienora), — H, F. Wickham. 



terminalis n. sp. 



The sex of the single specimen before me is not determin- 

 able vrith certainty, although probably male, as the sixth ven- 

 tral plate seems to be minutely and feebly emarginate at the 

 middle. 



Homalotusa n. gen. 



This genus resembles the European Ho7nalota Mann,, as 

 interpreted by Rey, but its members are usually materially 

 stouter. It appears to be a local type, though rather abun- 

 dant both specifically and individually. The four species be- 

 fore me are the following: — 



Form moderately stout, rather strongly convex, parallel, somewhat shining, 

 feebly micro-reticulate, the elytra more strongly and duller, the abdo- 

 men very minutely strigilate in broken transverse lines; punctures fine, 

 inconspicuous, rather more distinct and dense on the elytra, moder- 

 ately close-set throughout on the abdomen; pubescence somewhat 

 long, pale and distinct, subdecumbent; color rather pale piceous, the 

 abdomen darker, pale at apex, the legs pale; antenna infuscate, paler 

 basally, slender, moderately incrassate distally, attaining the tips of the 

 elytra, the second and third joints much elongated, the former very 

 slightly the longer, succeeding two longer than wide, six to ten nearly 

 as long as wide, the eleventh pointed, barely as long as the two pre- 

 ceding combined; head orbicular, as long as wide, arcuate and narrowed 

 behind the eyes, the neck four-fifths as wide, the eyes moderate, not 

 very convex, the surface evenly convex; prothorax about a fifth wider 

 than the head and a fifth wider than long, parallel, evenly arcuate at the 

 sides, the apex and base subequal in width, the surface even, with a 

 very small feeble rounded impression before the scutellum; elytra but 



^ slightly transverse, about a fifth wider and a third longer than the pro- 

 thorax, narrowly Impressed on the suture behind the scutellum, the 

 humeri but very slightly exposed at base; abdomen parallel^ slightly 

 narrower than the elytra. Length 3.9 mm.; width 0.85 mm. Mon-
