THE CANADIAN ENTOMOLOGIST. 23 



dark brown, the labellae slightly lighter ; clypeus brown ; eyes dark rich 

 brown. 



Thorax beautifully marked; prothoracic lobes dark brown, with dark 

 brown long flat scales ; mesonotum has the median part a light soft fawn 

 colour covered with light yellow or whitish curved hair-like scales 

 extending from the nape to the scutellum, except a small brown median 

 spot just cephalad of the scutellum, and connecting with the dark median 

 line ; this median part is bordered with a more or less distinct white line, 

 broadening toward the scutellum ; there are also broad submedian 

 yellowish stripes extending from the nape about half the length of the 

 mesonotum; laterad the mesonotum is dark rich brown; scutellum 

 light, continuing the colouring and scales of the medio-mesonotum ; 

 pleura rather grayish, with dark and white bands ; metanotum rich 

 yellowish brown. 



Abdomen grayish brown, covered with long light yellow hairs. 



Legs : coxae and trochanters light, with a little brown ; the very bases 

 of the femora light, otherwise the legs are a rich brown, with yellowish 

 knee-spots and narrow yellowish bands at the bases of most of the tarsal 

 joints, generally slightly including the apices of the preceding joint. 

 These bands are on all the tarsal joints of the hind legs, and lacking on 

 the fourth and fifth joints on the fore and mid legs; ungues simple and equal. 



Wings yellowish, with brown spots ; two small brown spots on the 

 costa near the base, and two large ones, the proximal including the sub- 

 costa and first longitudinal practically as much as the costa, with a small 

 extension on the root of the second long, vein, and a still smaller one just 

 under the distal end of the large spot; the distal large spot begins just 

 exterior to the junction of the subcosta with the costa, and ending a little 

 interior to the junction of the first long, vein with the costa, and extends 

 onto the first long, and upper fork of the second long, vein, with small 

 spots on the lower fork ; the distal end of the lower fork of the second, of 

 the third, of both forks of the fourth and of the fifth, have heavy dark 

 spots; wing-field somewhat spotted; fringe is dark except at the junction 

 of the first long, and costa, where it is yellow, and a pale spot midway 

 between the forks of vein 5 ; cells long, the first submarginal as long as 

 its stem, and a little longer and narrower than the second posterior cell ; 

 supernumerary and mid cross-veins meet, and are about equal in length, 

 posterior cross-vein about as long as the mid, and more than its own 

 length distant.
