A NEW CISIDE GENUS WITH NEW SPECIES FROM MANITOBA. 



BY CHARLES DURY, CINCINNATI, OHIO. 



Dolichocis, new genus. 



This genus is proposed for a species of narrow and elongate form, having 

 a combination of the characters of Cis and other described Ciside genera. It 

 has the antennae 9-jointed, the elytra finely beaded along suture. The pro- 

 thorax at side edges strongly margined and finely serrate. 



Dolichocis manitoba, n. sp. 



Elongate, narrow, oval in form. Brownish piceous in colour, when mature. 

 Vestiture of rather sparse, pale setae. Punctures deep and strong, those of 

 prothorax closer and finer than those of elytra. Head — epistoma subtruncate 

 and margined. Palpi thick, with terminal joint oval and blunt at tip. Pro- 

 thorax as long as wide, with sides rounded, margined and with finely serrate 

 edges. Elytra two and one-fourth times as long as wide. Beneath the pro- 

 sternum is flat between coxae, and long before them. Fore tibiae not produced at 

 outer tip. Males with a sharp, round fovea on first ventral. Length 2 mm.; 

 width 07 mm. 



Aweme, Manitoba. Norman and Talbot Criddle. From fungus growing 

 on ash and elm. Twenty specimens; in the Canadian National Collection at 

 Ottawa, Ont., and in my collection at Cincinnati, Ohio. 



Cis criddlei, new species. 



Elongate, with sides straight, colour piceous, vaguely paler on posterior 

 third. Vestiture of conspicuous hairs arranged without order. Head with 

 epistoma truncate and narrowl^y reflected. Prothorax as wide as long, sides 

 feebly rounded. Hind angles viewed from above almost right angled. 

 Punctures dense and deep. Elytra twice as long as wide, more sparsely and 

 coarsely punctured than the prothorax. Beneath, the male has a large fovea 

 on first ventral segment. Length 2 mm.; width 1 mm. 



Aweme, Manitoba. Norman Criddle. Eight specimens; in Canadian 

 National Collection at Ottawa, Ont., and my collection, Cincinnati, Ohio. 

 This species is the size and shape of Cis wenzeli, but differs from that and all 

 other species known to me in structural characters.
