Genus Melanoconion. 507 



^11 light, with faint light brown spots on some of the segments ; 

 hind tibiae dark near apex, first tarsals light and the rest 

 brown, i.e. pale brown with light basal bands on the second, 

 third and fourth segments, the fifth segment covered entirely 

 with light brown scales. Ungues simple and equal. 



Wings clear, covered with brown and white (or light yellow) 

 broad scales, the ajDical ends truncate and notched ; the ventral 

 scales obovate or clavate and very thin and white. There seems 

 to be no arrangement into spots, the wing being simply 

 " speckled." First sub-marginal cell is nearly twice as long and 

 a little narrower than the second posterior cell, its stem being 

 about one-half the length of that of the posterior ; mid and 

 supernumerary cross-veins are about equal and meet, the posterior 

 oross-vein nearly twice as long, and a little more than its own 

 length distant. On the costal edge the scales show something of 

 the spinous shapes found in Uranotaenia. Halteres pale. 



Length. — 3*5 to 4 mm. 



Habitat. — Bazambang, Pangasinan, Luzon, Philippine Islands. 



Time of capture. — September 11th. 



Observations. — This species was placed by Miss Ludlow in a 

 new genus, O'Beillia, she not knowing at the time of the genus 

 JStorleptiomyia, through my delay in sending the paper defining 

 it. The specimen was sent her by Captain Chamberlain from 

 Camp Gregg with a note, " Outside screens of screened house. 

 Rainy night." 



It is evidently a very marked species of Etorlcptiomyia.

Additional observations on habits, etc. — Professor Glenn 

 Herrick* states that " the larvae and pupae occur abundantly in 

 ponds and ditches when the water contains plenty of algae. I 

 have taken larvae in deep water among surface algae about an 

 old log. They are remarkable for their long respiratory tubes 

 which are dark on the distal fourths. The anal flaps are long 

 and slender. The antennae are covered (sparsely) with short 

 dark spines, and at the offsets, about two-thirds of their length, is
