CERAMBYCIDyE 263 



of the body, as would be implied, now known among the other 

 species of the genus. The close allies of crassipes may be distin- 

 guished as follows; since the coloration in both sexes is constantly 

 as above described, only the salient points of difference will be 

 mentioned : 



Metepisternum coarsely punctured posteriorly, finely and densely so 

 anteriorly; elytral punctures throughout well separated, moderate 

 in size basally, fine distally; male antennae extending nearly to the 

 tips of the elytra; pronotal punctures small but perforate, very close- 

 set but distinct; female elytra parallel nearly to the tips, there 

 rather rapidly rounding. Length (cf 9) 9.0-11.7 mm.; width 2.8- 

 3.7 mm. Pacific coast (from Sta. Cruz Co., Cal., to Vancouver 



Island), [xanthogaster and fasciventris Lee.] crassipes Lee. 



A Nearly similar, except that the head and prothorax are relatively 

 smaller, the latter shorter and with the fine punctures so dense as 

 to be discerned individually with difficulty; elytral punctures 

 basally distinctly more close-set; antennae (cf ) a little shorter. 

 Length (o 71 ) 9.0 mm.; width 2.8 mm. California (Mount Shasta). 



shastana n. subsp. 



Metepisternum coarsely punctured throughout; body black, shining, 

 the abdomen yellow, with faintly dusky fasciae; legs pale; antennae 

 pale, dusky at base and on the outer joints except toward their 

 bases, the tenth joint more than twice as long as wide; prothorax 

 strongly punctate, the punctures separated by their own diameters 

 or more medially; elytra (9) parallel but gradually narrowing 

 from slightly behind the middle, very gradually rounding to the 

 narrow sutural truncatures, the punctures sparser than in the pre- 

 ceding. Length (9) 10.5 mm.; width 3.0 mm. Vancouver Island. 



Vancouver! n. sp. 



Metepisternum finely, more closely punctured throughout, with a few 

 larger punctures interspersed posteriorly; body much larger, stouter, 

 similar in coloration, except that the slender abdominal fasciae are 

 black in the type; antennae shorter and stouter, the tenth joint (9 ) 

 not quite twice as long as wide; prothorax larger, everywhere ex- 

 tremely densely and evenly punctate, the punctures fine but deep, 

 perforate and distinct; elytra parallel to near the tips, there rapidly 

 rounding as in crassipes, the punctures finer and sparser, except 

 through a relatively shorter distance basally, the maculation nearly 

 similar, except that the median lateral spot is more transverse and 

 more broadly isolated; abdomen more densely punctulate. Length 

 (?) !3-5 mm.; width 4.3 mm. California (locality unrecorded). 



muliebris n. sp. 



The different outline of the elytra posteriorly in vancouveri, is 

 well marked and distinctive, as well as the stronger and sparser 

 thoracic sculpture; muliebris also has a distinct appearance when 

 compared with the female of crassipes.
