 (Townes) . 



This subspecies ranges from the Rocky Mountains to the Pacific 

 Ocean, from Colorado and central California northward into Canada. 



8b. Trycliosis semirubra semirubra Townes 



Phygadeuon annulatns Provancher, 1875, Naturaliste Canadien, vol. 7, pp. 179, 

 182; 9. Name preoccupied by Cresson, 1864. Type: 9, Quebec (Quebec). 



Trychosis semiruber Townes, 1944, Mem. Amer. Ent. Soc, no. 11, p. 254. New 

 name. 



Male: Black. Maxillary palpus white, its first segment brown; 

 labial palpus brown; tegula blackish brown; front and middle legs 

 beyond trochanters fulvous, their fifth tarsal segments bro\vn and seg- 

 ments 2-4 of middle tarsus paler fulvous or whitish ; middle femur often 

 darkened basally; second hind trochanter partly ferruginous; hind 

 femur ferruginous, its apex wealdy mfuscate; hind tibia blackish 

 brown; segments 1-4 of hind tarsus white, the basal 0.3 ± of the fii'st 

 segment brown; segment 5 of hind tarsus dark brown; wings tinged 

 with brown; abdomen ferruginous, the fii'st segment darkened basally; 

 tergites 5 and following largely or entirely black. Sometimes tergite 

 4 is wealdy infuscate apically. 



Female: Black. Palpi dark brown, the last three segments of 

 maxillary palpus light bro\vn ; flagellum blackish brown, brown basally 

 beneath, with a white incomplete band that covers about four seg- 

 ments; tegula blackish brown; coxae and trochanters reddish brown 

 to blackish brown; front and middle legs beyond trochanters dull 

 brownish fulvous, their tarsi a little darker apically; hind femur 

 brownish fulvous; hind tibia dark brown; hind tarsus brown, its 

 second through fourth segments paler brown or tinged with whitish; 

 wings tinged mth brown; abdomen ferruginous, its first segment 

 usually a little darkened basally, tergites 5 and following fuscous. 



A series of one male and three females was reared from the lenticular 

 egg cocoons of a drassid spider found under stones in South Cheyenne 

 Canyon, Colorado. The females have a white mark on the flagellum, 

 so are classified with this subspecies, while the male has the hind 

 basitarsus entirely blackish and is classified with the subspecies pulla. 

 This arbitrary division of a series into two subspecies will raise the 

 eyebrows of some of our friends, yet if one establishes subspecific 

 categories on certain characters, ignoring those characters in incon- 

 venient cases means a subjective sorting of specimens, which may be 

 less defensible than the division made here. To classify such a series 

 as "intermediate" means the establishment and definition of an 

 "intermediate" category, which only adds another division which may 

 itself be more arbitrary than the original two subspecies.
