usual ; the lower branch endiug just above the wing-tip ; the 

 short, upright marginal cross-vein joined to the 1st vein, where 

 it turns suddenly upward at its tip into the costa ; ])riefurca 

 divided into about tliree equal sections, the origin of the 3i-d vein 

 being at the end of the first section, the marginal cross-vein at the 

 end of the second ; the 3rd vein emerging at a rather wide angle, 

 in a line with the basal section of the praefurca and for about as 

 long as that section, afterwards merged in the 4th longitudinal 

 vein at the upper basal corner of the 2nd posterior cell ; upper 

 branch of 4th vein forked at one-third of its length, the veinlets 

 parallel ; the 4tli vein forking a little beyond the origin of the 

 3rd vein ; the basal side of the 2nd posterior cell rectangular ; 

 the iow^er branch of the 4th vein nearly in a line with the basal 

 section, the whole vein describing a gentle curve ; posterior cross- 

 vein situated just before fork of 4tli vein, joining the 5th vein 

 (which is much fore-shortened) at the point where it suddenly 

 bends down and joins the 6th, tluis closing the anal cell ; the 

 short terminal portion of the 5th vein practically in a line with 

 the posterior cross-vein ; the 6th vein quite straight, tlie 7th very 

 short, only one-third as long as the 6th, curved suddenly into the 

 margin of the wing. Halteres pale. 



Length 4 millira. 



Described from a type-specimen from Lucknow, o.iii. 11, two

GrENOTYPE, Cylindrotoma albiiarsis, Dol. ; by present designation. 



This genus differs from Moncjoma, Westw., also in the venation 

 only ; principally by the punctiform contact of the 2nd longitudinal 

 vein with the discal cell, thus obliterating the 3rd vein. The 

 discal cell emits only three veins, for arguing from analogy and 

 comparing the wing with that of Mongoma, it should be the anterior 

 branch of the 4th longitudinal vein that is forked, thus making 

 only three posterior cells, of which the 1st and 2nd are of equal 

 length, and with pointed bases. The anal cell is open somewhat 

 narrowly but distinctly. 



Range. Java. 



The only Eastern species that at present is referable to this 

 genus is P. albitarsis, Dol. (Nat. Tijds. Ned. Ind. xiv, p. 391, pi. iv, 

 fig. 1), wliich has not yet been found in British India, being 

 originally described from Java, and apparently not having been 

 seen since. 



Doleschall's figure is rather carelessly drawn, as the 1st longi- 

 tudinal vein is shown emerging from the auxiliary vein near its 

 tip ; the 2ud vein is straight after the bend, which talces place at
