298 THE CANADIAN ENTOMOLOGIST. 



Thorax : dorsum dark brown, heavily covered with dark brown 

 slender curved hairs, laterally light, covered with light golden curved 

 scales, forming a large spot over and around the wing joint, and running 

 in a line cephalad on the edge of the mesonotum, light bristles over the 

 wing joint ; pleura and prothoracic lobes almost white ; scutellum, dark 

 brown median lobe, and light lateral lobes, both covered with dark brown 

 slender curved scales, six large and a few small bristles on the mid-lobe, 

 four bristles on the lateral lobes ; metanotum dark brown. 



Abdomen light, thickly covered with dark brown flat scales, having 

 deep blue iridescence ; very large basal lateral light spots forming an 

 almost continuous lateral yellowish stripe, also continuous v/ith the venter, 

 which is very light yellow, almost white. All the segments heavily 

 haired. 



Legs: coxae and trochanters all light. In the fore legs the femora are 

 brown dorsally and ventrally light yellow, growing darker toward the 

 apex, tibicTS brown (giving red-bronze and purple lights), metatarsi brown, 

 with tiny light apical bands, tarsal joints brown, the first and second also 

 with light apical bands. Ungues unequal, very large, one bi-serrate and 

 the smaller almost straight. Mid-legs much as in fore legs; there are tiny 

 light bands on the metatarsi, and first and second tarsal joints, and in 

 some lights the whole metatarsus looks light. Ungues as in fore legs. 

 Hind legs have femora brown, with red reflections, tibiae brown, with light 

 apical bands. There are also narrow apical bands on the metatarsi and 

 first and second tarsal joints, the remainder of the hind legs is missing. 

 In some cases the bands seem slightly to involve both joints, but in any 

 case they are minute. 



Wing light, and apparently partly denuded, but there are rather 

 broadly truncated, sometimes slightly asymotric dark scales, with dark 

 blue-green iridescence on costa, subcosta and ist long vein and a few of 

 the same " broad-ended" scales on the other veins ; ist submarginal cell 

 is about one-third longer and a third narrower than the 2nd posterior, the 

 base of the latter, however, being well interior to that of the ist sub- 

 marginal. Stem of ist submarginal about one-third longer than the cell, 

 and somewhat longer than that of the 2nd posterior. Mid cross-vein is 

 about same length as-supernimierar)', which it meets, and posterior cross- 

 vein is about one-fourth longer, and is distant from the mid about three- 

 fourths of its own length. Halteres light, knob brown scaled, Length, 

 4.5 mm.
