confluent, a slightly broader line that widens out in front, 

 becoming obsolete at about the anterior third of the median 

 stripe; anterior ends of the lateral stripes slightly brownish; 

 interspaces of the dark brown groundcolor, interrupted op- 

 posite the anterior ends of the lateral stripes where the påle 

 gray margins of the lateral and median stripes become con- 

 fluent; interspaces with dark brown setigerous punctures; 

 remainder of the mesonotum påle reddish, the scutum hea- 

 vily gray pruinose, the scutellum and postnotum sparsely 

 pruinose. Pleura light gray with a narrow brown dorsal 

 longitudinal stripe, beginning on the propleura, continued 

 caudal almost to the base of the halteres, interrupted for a 

 short space beneath the wing-root. Halteres dark brown, 

 the bases of the stem and knob påle. Legs with the coxae 

 påle brown, sparsely pruinose; trochanters dull yellow; fe- 

 mora dull yellow, immediately before the tips with a narrow 

 brown ring; tibiae brownish yellow, the tips narrowly brown; 

 tarsi light brown. Wings whitish subhyaline, with a heavy 

 brown and gray pattern; cells C and Se strongly yellowish; 

 cell Se with three dark brown areas, the smallest at the end 

 of the cell, the other two continued down into cell R and 

 there narrowly connected with one another by a longitudinal 

 brown line; the påle space between these areas is about 

 equal in size to the basal area but smaller than the larger 

 blotch at the origin of the sector; stigma dark brown, di- 

 rectly connected with a large brown area at the fork of i?5, 

 which, in turn, is connected along cell R3 with a large brown 

 mark near the wing-apex in the outer half of cell R2 and 

 the mos t of cell i?^; paler brownish gray areas in cell M 

 along vein Cw, this with a small yellowish spöt near three- 

 fourths the length of the cell; outer ends of cells Mi, 2ndM2, 

 M4 and most of Cui\ the anal cells are darkened except on 

 their basal half or less; the påle areas on the wing appear 

 as most of cell M, this mark sending a påle arm into cell 

 1st Rj, excepting its base and tip, and continued through 

 cell 1st M2 and R5 to the wing-margin or nearly so (the 

 extreme tip of the wing is injured in the unique type); 

 veins surrounding cell 1st M2 very narrowly seamed with 

 brown; the bases of cells Mi, 2nd M3, M4 and the extreme 

 inner angle of Cui påle; cell Cu is påle except for two small
