174 THE CANADIAN ENTOMOLOGIST. 



In addition to the type sierravagus Chamberlin, E. pusio Stuxberg, 

 and E, bipwictatus (Wood) belong to this genu?, as does probably also the 

 doubtful species E. 7nonticola of Stuxberg, which I formerly have 

 regarded as probably the same as sierravagus but which agrees rather 

 better with adult /^/j/^, a species which Stuxberg based on a very young 

 and immature specimen, though differing according to the published des- 

 cription from either. 



Genus Zi7iapolys gen. nov. 



Each lateral margin of the head distinctly broken a little in front of 

 caudal third of its length as in the preceding genus. Prosternai spine 

 immediately caudal of the ectal prosternai tooth on each side ; prosternai 

 teeth large and uniformly spaced, no diastema separating them on each 

 side into two groups. Gonopods of male distinctly biarticulate. Basal 

 spines of gonopods of female 6 + 6. Claws of legs, especially of the more 

 caudal pairs, long and rather slender, all with two accessory claws. Coxal 

 pores in a single series on.each coxa of the last four pairs of legs. (Coxae 

 of the last two pairs of legs each armed with a stout ventral spine). 



Type. — Z. zipius sp. nov. 



The type is the only species of the genus thus far known. 



Zinapolys zipius s p. nov. 

 Antennae short, composed of 20 articles; the articles beyond the large 

 second one of moderate length, becoming shorter proximad of the ulti- 

 mate ; hairs clothing the articles usually long, mostly oblique to surface ; 

 not very dense. Eyes composed of about twenty ocelli arranged in four 

 series, eg. i + 5, 5, 4 (3). The single ocellus not very large. Organ of 

 Tomosvary large, exceeding an ocellus, well removed from the eye-patch. 

 Prosternai teeth 6 + 6-7 + 7, the most ectal on each side largest; the 

 others decreasing from this one to the mesal incision. Spine moderately 

 stout at bise but apically long and bristle-like. Angles o( none of the 

 dorsal plates produced. Gonopods of male distinctly biarticulate, the 

 distal article much narrower than the proximal ; subconic, pale. Claw of 

 gonopods of female entire, curved, deeply hollowed out on ventral side. 

 Basal spines 6 + 6, mostly thickest at middle, being acuminate distad and 

 somewhat narrower at base. Coxal pores circular to transversely sub- 

 elliptic, moderately large and distinct; 4, 4 (5), 5, 5. Spining of legs : 

 first to seventh, J^JI^H' eighth to eleventh, jfgil ; twelfth and thirteenth, 

 JM|:r; penult, i-544l ^"<^ '' rTTTTT?)- ^^^ ^^^^ terminating in three claws. 

 Last two pairs of cox^ç armed laterally as well as ventrally and dorsally.
