One adult male and t liree' ;i(lull females of what appear to 

 he exani])les of (lu^ ui'iuis ( 'li<-inshiin'i(, hnve recently come to 

 hand, and till, accoi'dinti' lo notes by Air. A. A. Girault, who 

 (•(dleoted tlicni, wi're ohlained in foi'est count it, in the Nelson 

 district, Nortli (^iieenshind, t'rnm nnder log's. In addition to 

 these there is also a haH'-growii female from forest coinitiT in 

 the same district. The latter was included in a small collec- 

 tion of ground-running and ai'l)oreal forms. Doubtless it was 

 too young to liaA^e a permanent home, and was in the wander- 

 ing stage. 



In the adult specimens before me, there is a sti iking differ- 

 ence between the sexes in general appearance. In the male 

 the ceplialothorax is black with hoary hairs, while tbe legs and 

 abdomen are, more or less of a very dark-brown (almost 

 black). Again, in the male, the cephalic segment is decidedly 

 raised, while in the female, the cephalic and thoracic segments 

 are almost on the same plane. In both sexes there is an ocular 

 tubercle, but that of the male is much the higher. In his 

 de6nition of the genus Chenistonia Mr. Hogg says : — " The 

 front row of eyes is slightly procnrved, the side eyes being 

 larger than the middle." This is absolutely correct in respect 

 of the female example of the species for which I pi'opose the 

 name ( 'lieiiii^toin'u (jirmiltl, but in the male on the other hand, 

 the front side eyes are no larger than the front median. In 

 this respect it will ap])arentl3^ be necessajy to ajnend Hogg's 

 definition of the genus, so as to read: — " Side eyes as lai'ge as 

 or larger than, the front middle." The generic position of 

 the male is easily determined by the [jresence of the powerful 

 single spur, springing from the middle of tibia i. 



This s])ecies I have named in honour of the collector, Mr. A. 

 A. Girault. The description is as folloAvs : —
