Refugio Co., Texas, December 11, 1912 ; and skin #252139, 
collected by F. S. Hersey, St. Micheal, Alaska, June 3, 
1915. Holotype and allotype deposited in the Museum of 
Comparative Zoology. Paratypes will be distributed to

Discussion : This enigmatic species seems to be inter- 
mediate between Gruimenopon and Heleonomus. The 
ocular and cervical sclerotizations, the general head 
shape and the male genitalia all seem to be more closely 
allied to Heleonomus . In other features, such as shape 
and chaetotaxy of thorax and abdomen, it is like members 
of the genus Gruimenopon, in which genus it is retained 
because these features seem more significant generically.
