22 B. C. ENTOMOLOGICAL SOCIETY 



ven^ fine pale pubescence ; the setae very conspicuous on vertex, lateral 

 margins of pronotum, and legs ; ventral surface similarly clothed, the 

 setae less conspicuous. 



Vertex very finely roughened, its least width about equal to the 

 transverse diameter of an eye, provided with diverging grooves before 

 the ocelli, the latter separated by a space slightly greater than the 

 diameter of one of them, and three times as far from the eyes as from 

 each other ; the transverse carina between frons and tylus obsolete at 

 middle ; tylus elevated, moderately swollen at base ; postocular portion 

 of head very short. Antennae slender, as long as pronotum and scutel- 

 lum ; the first segment much the thickest and slightly shorter than least 

 distance between eyes (9-10), almost as long as the third (9-10) ; second 

 very slender, very slightly curved, a little enlarged toward apex, twice as 

 long as the first; third almost cylindrical, slightly shorter than the fourth 

 (9-11), which is slightly thicker than the third and cylindrical except 

 at ends. Pronotum polished, transverse, more than three times wider 

 than long/47-14); lateral margins slightly curved, convergent, anterior 

 angles evenly rounded ; the anterior margin a little narrower than head 

 including eyes ; posterior margin broadly emarginate, slightly and evenly 

 curved across middle; callus prominent, convex, not reaching lateral 

 margins, with three discal indentations of which the middle one is 

 deepest, the lateral faint; transverse impression deep, curved, minutely 

 punctate at bottom ; posterior lobe about one-half as long as preceding 

 on median line. Scutellum polished, as long as wide, the impression 

 sinuate, situated slightly in front of middle, the posterior lobe longer 

 than the anterior (20-13) on median line. Hemielytra moderately con- 

 vex, the costal margin strongly curved, broadly flattened and slightly 

 refiexed anteriorly ; corium faintly shining, very obsoletely punctate ; 

 clavus opaque ; veins distinct, the inner forked, with branches reaching 

 membranal suture; membrane with four areoles, the inner longest, 

 extending anteriorly about one-seventh of its length beyond base of the 

 next, posteriorly almost as far as the next ; outer margin of membrane 

 thickened and pubescent. Second segment of hind tarsi about as long 

 as the third. Last ventral segment of female more than twice as broad 

 as long (38-14), somewhat produced and broadly rounded at middle. 

 Form rather broadly oval. Length male and female 4.8-5.0 mm ; width 

 2.5-2.7 mm. 



Plolotype, male. Beaver Lake, Saanich Dist., B. C, 17-VI-'19 

 (W.D.), in the National Collection at Ottawa. 



Allotype, female, same data, in my collection. 



Paratype. female, Vernon. B. C, 26-IX-'18 (W.D.), in Downes' 

 collection. 



This species is closely related to interstitialis Say, from which it is 

 distinguished by the long pubescence, evenly rounded anterior angles 

 of pronotum, shining surface, etc.
