THE CANADIAN ENTOMOLOGIST. 373 



rugulose, while on the mesonotum it is nearly coarse enough to appear as 

 dense punctures ; caudal margin of the mesoscutum nearly straight, the 

 pronotum distinct, about a fourih the length of the mesoscutum, not nar- 

 rowed mesad ; axilh^ widely separated. Parapsidal furrows indicated 

 cephalad by an impression, but incomplete, yet extending about two-thirds 

 the length of the mesoscutum. Metaihoracic spiracle not conspicuous, 

 oval. Metathorax not as long as the scuteUum, with a rather short and 

 broad median carina (Coddington lens, ^4-inch), the disk peltate with its 

 wings slightly impressed and margined laterad, extending to within a 

 short distance of the spiracle along the cephalic margin, and with its 

 carinated or margined sides extending caudo-mesad to the meson at the 

 insertion of the abdomen where the disk has a very short neck ; a longi- 

 tudinal spiracuiar sulcus on the dorso-lateral aspect of the metathorax 

 leads from a point just caudo-mesad of the spiracle to the caudal margin 

 of the segment. Metathoracic pleura dorsad with a ie.w long, whitish 

 hairs. 



Abdomen conic-ovate, widest at the 4th segment and thence 

 caudad, conic ; segment 2 longest ; segments 3, 4 and 5 subequal, each 

 one-third shorter than the second segment, but wider ; petiole, or the first 

 segment, sessile ; abdomen not quite as long as the head and thorax com- 

 bined ; hypopygium not exserted ; venter not ])roduced ventrad, not 

 convex. Legs normal, the proximal tarsal joint of caudal legs longest, 

 one-fourth longer than the second joint, the 3rd, 4th and 5ih joints much 

 shorter, the 4th shortest; tibial spurs of caudal legs siiigle. Thoracic 

 pleura sculptured like the pronotum, including also the coxte and femora 

 of all of the le^s. 



Fore and hind w'ings normal, usually densely ciliate in the disk and 

 with moderately short marginal cilia, the marginal vein in the fore wing 

 less than a half the length of the submarginal vein, moderately short and 

 stout and about a fourth longer than the postmarginal vein ; the latter 

 equal in length to the stigmal vein, the latter bifurcate at its extremity, or 

 rather with a slender nipple-like projection from its cephalo-lateral margin 

 at a distance from the apex of the stigmal vein equal to the length of the 

 projection { = imais of Thomson). 



Scape long and slender, cylindrical, as long as the combined length 

 of the pedicel, the two ring-joints and the first two funicle joints ; pedicel 

 small, obconic, about a third longer than the combined length of the two 

 ring-joints and a third shorter than the first funicle joint ; the latter the 

 longest joint of the flagellum, about as long as the combined lengths of
