THE CANADIAN ENTOMOLOGIST. 177 



of bristles, its cephalic margin angularly convex, subacute at the meson. 

 Metanotum normal. Abdomen short and stout, subtriangular, not quite 

 as long as the thorax, flat dorsad and not pubescent, shining, but with the 

 squammose sculpture of the thorax, which, however, is more delicate on 

 the abdomen. Sheaths of the ovipositor slightly exserted, ochraceous. 

 Fore and hind wings densely ciliate in the disk ; marginal vein of the fore 

 wing short and thick, but slightly longer than wide, the stigmal vein nearly 

 as long as the marginal and postmarginal veins combined; the latter slightly 

 shorter than the marginal vein ; fore wings extending for nearly one-half 

 their length beyond the abdom'en ; a subcuneate hairless line with its apex 

 just caudad of the stigmal vein runs from that vein cauda-proximad 

 through the fuliginous area to the caudal wing margin, where it is widest • 

 this hairless line is not conspicuous ; joining it, or originating from it, 

 near the caudal margin, is a narrow, curved white line, which runs apicad 

 through the fuliginous area to its apical margin, where it splits into two ; 

 also, this line is not very conspicuous. There is also in the fore wing an 

 inconspicuous, more deeply-coloured spot beneath the submarginal vein 

 just proximad of the oblique hairless line, and running somewhat parallel 

 to it. Immediate base of fore wing naked. 



Antennae ii-jointed, inserted at the clypeal border; scape with a 

 conspicuous, dorso-ventral, leaf-like dilatation or expansion, the dilatation 

 appearing just beyond a short peduncle and extending to the apex, and of 

 itself hemi-pyriform ; scape longer than pedicel and joints i and 2 of 

 funicle combined, the expansion with some punctures ; flagellum normal, 

 cylindrical and regularly clavate, and the club normal. Pedicel obconical, 

 longer than any of the following joints, and slightly shorter than the com- 

 bined lengths of joints i and 2 of the funicle ; first funicle joint two-thirds 

 the length of the pedicel, and slightly shorter and narrower than funicle 

 joint 2 ; funicle joints 2 and 3 subequal, joint 3 slightly thicker, both 

 longer than joint i, and still more so than the three following joints; 

 joints 4, 5, 6 of the funicle quadrate, subequal, one-third shorter and wider 

 than joint 3 ; the club regularly conical, about the same length as the 

 combined lengths of joints 4, 5 and 6 of the funicle, its basal, joint one- 

 third longer and slightly wider than funicle joint 6, and as long as, and 

 much wider than, funicle joint 3 ; the intermediate joint is one-third 

 shorter and slightly narrower than the basal joint, and narrows cephalad ; 

 the apical joint of the club conic, equal in length to the basal joint. 

 Antennae hispid.
