PAEABEUKETTIA. 251 



Length 3 millim., expanse of wings 8 millim. 



" The original specimens were taken at an altitude of about 

 6000 feet at Kurseong during the 'rains' (July) on a window- 

 pane and on the upper surface of a fern-frond. They rested with 

 the wings spread out quite flat. I have recently (June 1910) 

 taken other specimens at the same place. They were running 

 erratically on the leaves of CaJadium in dense jungle at dusk."

Genus PARABRUNETTIA, Bnm. 

 Parabrunettiu, Brunetti, llec. lud. Mus. iv, p. 311 (1911). 



Genotype, Psijchoda squamlpennis. Brim. 



This genus differs from Brunettia primarily in the fact that the 

 3rd longitudinal vein ends at the tip of the wing and not heloiu it. 

 Its other distinctive characters are : — (1) The presence of closely 

 placed dark imbricating scales on at least some considerable portion 

 of the wings, on both their upper and lower surfaces, or on the 

 underside alone *. (2) The surface of the wing generally rather 

 thickly covered to some considerable extent with more or less 

 longitudinally placed hairs t- (3) Chjetse present on the flagellar 

 joints (possibly not on all of them), irrespective of the apical 

 joint, which, even in B. superstes, is devoid of them : they are 

 not so large or so conspicuous in any of the species as they are 

 in B. superstes, and appear to vary a good deal in size, according 

 to the species. % 



In many species there is a rather noticeable patch of long smooth 

 depressed silky hairs extending posteriorly from the alulse, which 

 may probably figure as a secondary character of the genus. 



Owing to the denseness of the vestiture of the wings (the basal 

 hairs, the surface hairs, and the opacity of the scales), it has been 

 impossible to note the exact position of the forking of the 2nd 

 longitudinal vein in some of the species, but in all those in which 

 it has been noted it occurs beyond the origin of the 3rd longi- 

 tudinal vein. 



* Any species (if discovered) wiib scales on the iipperside of tbe wing only, 

 would logically fall into the genus. 



t These are absent, in two species provisionally placed here ; but this may 

 be better regarded perhaps as a secondary character, as species both with 

 and without hairs on the surface of the wings occur equally in Psychoda and 

 Pcricoma. 



\ Similar chsetse, but much smaller, have been detected by Dr. Annandale 

 in Pcricoma margininotata and Psychoda distiiuia ; so they cannot be considered 

 of generic importance.
