distinctly smaller than anterior and upper ones. Proboscis thick, 

 apparently moderately long but mainly concealed within the 

 mouth opening, probably producible; palpi elongate, a little 

 pubescent, apparently of one joint only. Antennae elongo-cylin- 

 drical, nearly filiform, two-thirds as long as head and thorax 

 together; ist joint about twice as long as broad, 2nd about half 

 this length ; flagellum with eight distinct annul ations, subequal, 

 except the last which is rather longer and pointed. 



Thorax approximately oval, widest at level of wings, only 

 slightly arched ; microscopically pubescent here and there. Scutel- 

 lum of moderate size, semicircular or sub-triangular, unspined. 



Abdomen apparently 5 jointed, the emargination between the 

 2nd and 3rd joints extremely indefinite, possibly these forming but 

 a single joint. The ist joint very short, transverse, 2nd as wide 

 as 1st at base, thence suddenly narrowing at half its length to 

 cylindrical form, the 3rd at base as wide as tip of 2nd, rapidly 

 widening to tip : the abdomen widening to tip of 4th segment, 

 thence rapidly narrowing, the tip rounded, the 2nd to the 5th 

 segments subequal in length. Abdomen with a little soft pubes- 

 cence towards sides at base. Genitalia exposed, fairly complex, 

 consisting of a dorsal plate and a pair of two-jointed hairy claspers, 

 with, apparently, at least one other pair of appendages. 



Legs quite slender, moderately long, minutely pubescent ; 

 hind legs longer and slightly stouter, hind femora barely thick- 

 ened towards tips, hind metatarsi distinctly incrassated, larger 

 and longer than the remainder of the tarsus ; 4th tarsal joint of 

 all the tarsi distinctly shorter than any others. 



Wings well developed, fairly broad, a little longer than al)do- 

 men, venation as in Pachygasier , distinct, halteres large. 



N.B. — In my table of genera (Rec. Ind. Mus. I, 89) this genus 

 will separate from Salduba, Walk., on the following characters : the 

 pedunculated abdomen, the different construction of the antennae, 

 the longer wings (unless Walker by a lapsus calami has written 

 thorax instead of abdomen, which seems probable), and lastly on 

 the greater breadth of wing. The differences in the abdomen and 

 antennae alone are sufficient to require a new genus.

Head. — Eyes contiguous for one-fourth the distance from 

 vertex to antennae, vertex rather depressed, with conspicuous 

 ocellar prominence, wholly black. Frontal triangle brownish-yel- 

 low, bare, shining, flush with e^-es. Face lighter brownish-yellow, 

 with almost microscopic whitish pubescence, and two large circu- 

 lar black spots below base of antennae. The hinder part of the 

 lower part of the head black. Proboscis and palpi brownish- 

 yellow, withdrawn, with a little pale pubescence. Antennae
