26 CONTEIBITTIONS TO CANADIAN PALEONTOLOGY. 



parallel to the first ; while from opposite the point of origin of the 

 last fork the third cluster takes its rise, starting as a shouldered vein, 

 which forks at its shoulder into two slightly divergent veins which 

 run subparallel to the previous veins ; but the innermost of these 

 again forks beyond its middle, crowding the veins together at this 

 point ; there is also a short, tenth, independent vein close to the 

 outer extremity of the produced coriaceous .field. The outer margin 

 of the wing is delicately wrinkled with a simulation of veinlets. The 

 abdomen is ovate, somewhat regularly tapering at its outer half ; the 

 apex obscure but apparently regularly rounded ; the pleurae are punc- 

 tured like the scutellum, while the dorsal surface is minutely and pro- 

 fusely but obscurely punctulate. Such portions of the chitine as 

 remain are of an intense black. The specimen is apparently a male, 

 but whether two small triangular pieces, nearly equiangular, following 

 the posterior edge of the sixth abdominal segment laterally, are to be 

 considered the anal cerci is doubtful. 



Directly beside this specimen, and, in fact,, partly underlying it, 

 are the abdomen and part of the sternum of another insect, which, 

 although much smaller, should doubtless be regarded as the female of 

 the same species. This abdomen shows the under surface ; it is 

 very rounded and ovate, the extremity well rounded, the sixth seg- 

 ment represented by a circular fissured plate. The sides of the abdo- 

 men are punctulate, as in the other specimen, but the punctulation 

 dies out before. reaching the middle of the abdomen. Little can be 

 said of the other parts of the body, excepting that the rostrum appears 

 to terminate at the front limit of the middle coxse, and the sternal 

 parts of the thorax are coarsely punctate as above and more particul- 

 arly at the margins of the separate pieces.
