THE CANADIAN ENTOMOLOGIST. 



lowish, femora mostly black in the male, anterior legs of female reddish, 

 patellee and tibiae of other legs reddish or with red bands. Abdomen red- 

 brown, in male with four black spots each side near tip, in female a black 

 stripe each side with three pale spots, as in D.flavus, sometimes a pair of 

 pale spots near base ; venter pale with three dark brown or black stripes. 

 In structure similar to D. flavus and D. montamcs, but the mandibles are 

 not enlarged as in those species, and the size is much smaller. The male 

 palpus is similar to D. montanus, but with a smaller tibial hook, a smaller 

 striate upper portion of bulb, and with a tube yet stouter and deeply bifid 

 at tip. The epigynum has a triangular excision behind, and a deeply 

 lunate dark patch in front. Several specimens ; Olympia, Washington 

 (T. Kincaid).

 thorax red brown, eye-region blackish, a narrow median light stripe 

 extending from the dark of eye-region to the hind margin of the cephalo- 

 thorax, also a light stripe each side from just below the dorsal eyes to the 

 hind margin, a few whitish hairs around anterior eyes, abdomen above 

 and below a uniform gray, sternum and legs brownish yellow, latter with 

 ends of the joints darker, mandibles reddish. Cephalothorax but little 

 shorter and narrower than the abdomen, barely wider behind the eye-

 row a little nearer dorsal than lateral eyes. Fourth pair of legs much the

 arated by more than width of lip ,; metatarsi IV. spined throughout. The 

 epigynum consists of a depressed area, broadly rounded in front and

 from them extend behind on each side a clavate body, enclosing between 

 their tips two elongate holes. One specimen ; Southern California.
