browUj the flagellmn pale brownish yellow, the distal 

 seo^tnents a little darker. Head dark brown. 



Pronotura dark brown. Mesonotal praescutum reddish 

 brown, darker medially and with three darker brown stripes ; 

 scutum with the lobes dark brown, the median area paler; 

 scutellum projecting, dark brown ; postnotura dark. Pleura 

 indistinctly striped longitudinally with whitish on a dark 

 brown background, the pale stripe lying just above the bases 

 of the coxae. Halteres brown, the knobs dark brown. Legs 

 with the coxBe larger than is usual in this genus, dark brown, 

 the tips paler; trochanters dark brown; remainder of the 

 legs broken, Wings rather long and narrow, the costal 

 region just beyond the origin of Rs curiouslj^ dilated, this 

 enlargement ending opposite Sci; wings pale, subhyaline, 

 the wing-base infuscated, continued as a cloud along vein Cu 

 to its fork ; a very large brown area occupies the region o£ 

 the costal dilation, including almost all of cell 1^/ i?i, 

 excepting only a small rounded hyaline spot beneath Sc^ and 

 the extreme tip of the cell ; this band also traverses cell R 

 to vein M and continues along the cord to the wing-margiti, 

 connected broadly across veiu -R4+5 plus M^^^ with the outer 

 blotch which appears as a broad seam along vein jRg that is 

 continued across cell R^ and the fork of R^j^^ plus Mi_^2', 

 the outer end of cell Rg ^^^ \'e,\i\ R^ are narrowly seamed 

 with brown ; veins yellow, dark brown in the darkened areas. 

 Venation : r is almost in alignment with i?i and the outer 

 section of -R2+S1 ^^^^ latter being very long, about twice as 

 long as i?2 or the basal section of -/^2+3 ; ^2 is almost straight 

 and subperpendicular to the end of It2+Z) giving to cell R2 

 a triangular appearance. 



Abdomen dark brown, the basal segments, especially the 

 sternites, indistinctly ringed with obscure yellow, this colour 

 embracing both the basal and caudal margins of the 

 segments. Ovipositor normal for this subgenus^ the valves 

 reddish horn-coloured.

This very small Trentepohlia is remarkable in the costal 

 dilation of the wings. It will be interesting to learn to what 

 extent this character is developed in the male.
