Chilopoda 21 h 



Claw of female gonopods long and well curved, cut ire, with no trace of lateral 

 teeth. Basal spines3 + 3; acuminate from near middle of lengl li. apically rounded. 



Length, 20 to 30 mm. 



Localities: Washington state; Pullman and Wenatschee. Oregon: Corvallis. 



This species seems to replace E. sierravagus north of Oregon. It is very 

 close in general appearance and structure to the latter species. 



Ethopolys integer alaskanus, n. subsp. 



Though in E. integer proper the head and first dorsal plate are strongly and 

 rather coarsely punctate, especially over the anterior portion of tic head, 

 these parts in the types of the Alaskan form as represented by the types are 

 smooth and wholly without punctse or nearly so. 



Posterior angles of thirteenth dorsal plate weakly produced, those of the 

 eleventh showing a more slight similar tendency. 



The claw of the female gonopods in the two typical females has a distinct 

 tooth on the inner side toward the distal end but none on the outer, being thus 

 bipartite instead of essentially entire as in integer or tripartite as in sierravagus. 



In the types from Forrester island a median dorsal black stripe is distinctly 

 marked from the caudal end of the fourteenth plate cephalad to the frontal 

 suture of the head. These specimens in whole or in part show a distinct reddish 

 or chestnut cast. The specimens from Sitka (males presumably of this sub- 

 species) lack the reddish tinge, the colour being a dull, nearly uniform, dusky 

 olive brown. 



Dorsal spines of first legs in Sitka specimens 0, 0, 2, 2, 1. Dorsal spines of 

 second legs in specimens from both localities may be 0, 0, 3, 2, 1 or 0, 0, 3, 2, 2. 



Length of maximum female, 23 mm. 



Localities: Alaska, Forrester island (Ronald and Prof. H. Heath); and 

 Sitka.
