N.B. — I retain all the species in the above two genera, which 

 appear ample for the species in this sub-family, the genera pro- 

 posed by the Rev. A. E. Eaton {Entomologist' s Monthly Magazine, 

 19045 P- 55) J appearing to me to be based upon insufficiently strong 

 characters, 



Psychoda bengalensis, mihi, sp. nov. 

 & 9 . Bengal. lyong. i-i| mm. 



Body entirely clothed with hair, varying from yellowish grey 

 to whitish, and of a nature varying from soft long hairs to bristly 

 ones, which latter on some parts, and around the tip of the 

 abdomen, are distinctly scale-like. In certain lights some of the 

 scale-like bristles appear blackish or even wholty black. 



Head: Eyes black, with very large facets; frontal groove 

 very narrow with long, greyish hair. Lower part of head covered 

 with long hair. Antennae fifteen-jointed; scape of two larger joints 

 egg-shaped; the fiagellum of ten joints of nearly uniform size, 

 each shaped like a long-necked flask, and three further ver^^ 

 minute joints, invisible except under a microscope. Each joint 

 of the whole antenna bears a rather thick verticel of hairs. Palpi 

 of four joints of equal length, with some hairs, last joint verj^ 

 thin, pointed. 



The genital process in the male consists of a pair of small, bare, 

 upper chitinous appendages, and a much larger and longer lower 

 pair, densely covered with long hair. In the female it consists of 

 a pair of very small, pointed, chitinous appendages forming a 

 small ovipositor, which it is somewhat difficult to distinguish 

 amidst the hair. 



Legs of the same colour as the body, clothed rather thickly 

 with concolorous scales, and with numerous black bristles, the 

 former being thickest on the tibiae and tarsi. 



Wings with all the veins bearing a double row of hairs, point- 

 ing respectivel}^ anteriorly and posteriorly. The fork of the upper 

 prong of the second longitudinal vein originates a little before the 

 middle hne of the wing ; and the fork of the fourth longitudinal 

 vein originates a little behind this middle line, but the linear space 

 between the two forks varies in different specimens. A few black 

 bristly hairs forming a small black spot occurs at the tip of each of 

 the four veins above the third longitudinal ( which is unmarked ) ; 

 also at the tip of the upper prong of the fourth, and at the tips of 

 the fifth and seventh. These black hairs gradually become more 

 scale-like towards the last spot, which is usually the deepest of all.^ 

 The whole border of the wing is thickly fringed with long blackish 

 grey hair, which extends over the tegulse also. 



1 In some specimens there is a collection of black hairs showing a tendency 

 to form an irregularly shaped spot at the base of the wing, and, more often, two 

 similar vague spots, one below the costa, the other above the hind border, both 

 near the base of the wing.
