longer than mesonotum ; tibiae of the female without lanceolate scales ; 

 last four joints of male antennae longer than basal ten. 



9 , head black, both extremities of each segment of the palpi whitish, 

 especially the anterior extremities ; central and major portion of each seg- 

 ment black ; proboscis with three narrow transverse whitish bands near 

 apex. Pile on antennas black, whitish at tips ; antennas reaching to about 

 the middle of the mesonotum ; joints globose, subequal, the last four being 

 larger and more oblong, especially the apical one, which is prolonged into 

 a short blunt point ; basal joint much larger and more globose than the 

 others ; sense organs, insertion and position of the pile and bristles on the 

 antennae as in C. bnnnalis ; mesonotum black, shining, pile black ; sides 

 of prothorax with a bunch of black bristles ; pleurae naked ; mesopleuras 

 whitish ; abdomen black, shining ; pile on posterior anal segments dirty 

 white, longer than on other parts, central portion of each segment of venter

strap-shaped, curved, bristly-fringed on convex side ; neuration of wings 

 differing from that of C. bnnnalis in the following points : subcostal cell 

 single ; only one anal vein ; no obsolescent veins in cubital or discal cells ; 

 anterior costal cell very narrow ; juncture of the veins at base of wings 

 more distinct. 



$ Coloration practically as in female, pile on entire insect longer, den- 

 ser and more erect than on female ; the basal joint of antennas as usual 

 much enlarged, globose ; joints 2-10 inclusive subglobose, graduating in 

 size toward apex and becoming somewhat oblique ; joints 11 and 12 much 

 elongated, subequal, tapering somewhat toward apex; joint 13 ovate-ob- 

 long, smaller and shorter than the apical one. Plumosity, pilosity and 

 sense organs of antennas as in C. brumalis ; also neuration of wings as in 

 female. 



Larva : 5-6 mm. long, bristly, and minutely black spinulose ; cylin- 

 drical, tapering slightly from the metathoracic segment toward base, 

 tapering rapidly toward the head ; dirty white. Head dark brown, eye 

 spot and mouth parts black ; tips of thoracic feet armed with a circlet
