1 9 13-] B. Brunetti : Diptera. 151 



(13-XI-08) both taken by Dr. Annandale) the relative lengths are 

 not constant, the hind metatarsus in one being about one and 

 three quarter times as long as the tibia. The abdomen in the 

 Dibrugarh specimen is tinged with dull red, and in one of the 

 other specimens referred to the legs are brown instead of black, the 

 tarsi being less white than usual. 



N.B. — Two specimens of Chironomus {sensii lato) are in the 

 present collection but are too damaged to identify. One is from 

 Dibrugarh, the other from Sadiya. 



PSYCHODIDAE. 



Psychoda notatipennis, mihi, sp. nov. 



(PI. vi, fig. 4). 



Sex ? N.E. Frontier of India. Long, barely i mm. 



Head crushed by pin but one perfect antenna remains and 

 this is densely covered with greyish white pubescence ; there are 

 also long whitish hairs about the frons. 



Body. — Pale yellowish, thorax mainly brown, abdomen with a 

 little blackish across the middle of the dorsum. Both thorax and 

 abdomen with rather long whitish hairs in moderate density. 

 Bell}^ yellowish with whitish hairs. 



Legs. — Dark brown with a Httle pale pubescence. 



Wings. — ^Clear, with two divaricate rows of fine whitish grey 

 hairs to each vein, the rows lying across one another between the 

 veins. Six small but very distinct spots composed of dark brown 

 hairs are placed in a transverse row at one third of the wing's 

 length, situated respectively over the auxiliary vein, ist vein, 2nd 

 and 4th veins at their forks, 5th and 7th veins, in the case of the 

 7th vein near its tip, which is nearl}^ opposite the tip of the ist 

 vein but rather more proximad. A second row of similarly formed 

 spots crosses the wing a little beyond the middle, the third spot of 

 which is a little more proximad than the others. In this second 

 row the ist spot is at the tip of the first ending of the 2nd vein, 

 very close to the costa, the 2nd (the largest) on the lower branch 

 of the 2nd vein, the 3rd spot (the most proximad one) on the 

 upper branch of the 4th vein, and the 4th spot near tip of 5th 

 vein, close to the wing margin. There is a similar spot at the tip 

 of the ist longitudinal vein, which lies on the costa, a little 

 proximad of the second transverse row of spots. Two other 

 similar spots are placed close to the wing tip, respectively at the 

 tips of the lower branch of the 2nd vein and of the upper branch 

 of the 4th vein. 



Described from a single specimen in good condition, except for 

 the partially crushed head, from Rotung, 1400 ft. (24-xii-ii), taken 

 under the leaf-stem of a decomposing plantain. 



Owing to the long hair at the abdomen tip it is not easy to 

 distinguish the sex. This specimen is the only one of this family 

 obtained upon the Expedition.
