THE CANADIAN ENTOMOLOGIST. 9 



the same, pallid at apical end ; trochanters dark; tibiae and tarsi pallid^ 

 the apical tarsal joint dark or black ; flagellum dusky ; ventum of thorax 

 and abdomen dark, purplish black. Tegul^e dark. Wings hyaline, 

 venation dusky, the fore wing with two dusky blotches along the cephalic 

 or costal margin, the first or proximal one at the junction of the submar- 

 ginal and marginal veins, rounded and about one-half the size of the apical 

 one, which is situated at the stigmal vein, and is more irregular in outline. 

 Eyes chestnut red ; ocelli ruby red. 



Head flat from lateral aspect, the occipital margin acute ; front 

 broad, concave, vertex narrow, broader laterad; eyes lateral, oval, covering 

 a little over a half of the lateral aspect of the head, the malar space 

 present ; antennae inserted, about on an imaginary line drawn between the 

 ventral ends of the eyes, the scape not reaching to the vertex ; lateral 

 ocelli on the narrow vertex at the occipital margin, distant from the eyes, 

 but farther apart from each other than each is from the eye margin, dorsal, 

 an imaginary line connecting them convex ; the cephalic ocellus barely 

 visible from dorsal aspect, cephalic, forming a flat triangle with the others, 

 and situated in the cephalic aspect of the vertex front, against the acute 

 occipital margm at the meson and closer to the lateral ocelli than they are 

 to each other. Head delicately shagreened, its surface not as coarse as 

 the surface of the eyes; the entire thorax dorsad moderately, coarsely, 

 polygonally reticulated, the parapsidal furrows mere impressions, incon- 

 spicuous, not well defined grooves, and from some aspects seen only 

 caudad ; pronotum visible from dorsal aspect, about one-third the length 

 of the mesocutum, the caudal margin of the latter, between the advanced 

 axillae, convex ; scutellum rounded, normal, convex, without grooved 

 lines; mesopostscutellum not large, crescentic, sculptured like the 

 scutellum ; metathoracic spiracle margined, distinct, short and broadly 

 oval ; metathorax slightly more delicately sculptured than the scutellum 

 and scutum of the mesothorax, and^with a delicate median carina, and 

 two others, on each side of the meson^ both curved and running caudo- 

 laterad from the caudal margin of the mesopostscutellum ; of these two 

 lateral carinse, the more laterad or cephalic one is the shorter. Coxae and 

 the thoracic pleura sculptured similarly to the metanotum, the cephalic 

 coxae less so; caudal coxae enlarged, subtriquetrous. Abdomen conic- 

 ovate, but very slightly produced or convex ventrad, longer than the head 

 and thorax combined and than the wings ; very delicately reticulated.
