THE CANADIAN ENTOMOLOGIST. 



oval, depressed, smooth and shining; the shield of the ist segment 

 linear, and with the posterior corners rounded off. Wings hyaline, the 

 stigma and most of the costs;, brown-black, the other veins brown ; areolet 

 large, closed. 



Described from one specimen. 



This species comes nearest to M. mamestrce Weed. 



OPIUS WESMAEL. 



(8) Ophis Canadensis n. sp. 



^ . — Length 2% mm. Black, polished ; the orbits broadly, the 

 face wholly, the scape and two or three flagellar joints beneath, legs, 

 including coxae, the lateral or membranous portion of ist and 2nd abdo- 

 minal segments, and the suture between the 2nd and 3rd, all honey- 

 yellow ; the posterior tibiae apically and their tarsi slightly dusky. 

 Antennae as long as the body, 35-jointed, brown. Wings hyaline, the 

 venation brown, the recurrent nervure almost interstitial with the first 

 transverse cubital, the median and submedian cells of an equal length. 

 Metathorax smooth, with some sparse, long bristles scattered over its 

 surface. The shield of the ist abdominal segment is longer than wide, 

 smooth, the disk impressed, the sides parallel ] the 2nd and 3rd segments 

 are slightly rugose, the following smooth, shining, sparsely hairy. 



Described from one specimen. 



(9) Opius bicarinatus n. sp. 



^. — Length 3I mm. Robust, black, shining and pubescent. 

 Head broad, rugosely punctate ; face with glittering pile ; palpi and legs 

 pale rufous, the posterior coxae black. The thorax has the parapsidal 

 grooves coarsely indicated and punctured at bottom, across the base of 

 the scutellum is a deep broad fovea, while the pleurae are rugoso-punctate. 

 The metathorax is finely rugose, and there is a large fovea on each side 

 of the post scutellum. Abdomen oval, depressed, rufous, the base and 

 apex black; the ist segment is the longest with two carinae on the 

 disk and rugose, the 2nd segment is also rugose, while the following 

 segments are smooth and covered with fine hairs. Wings hyaline, the 

 venation dark brown ; the 2nd submarginal cell is much narrowed at 

 apex, from an exceedingly short 2nd transverse cubital nervure, and this 

 will be found to be a good character to distinguish the species. 



Described from one specimen.
