Wings with yellow veins ; the small costal bristle is black ; the yellow band at 

 the fore border extends from the base of the wings to the tip of the 3rd vein, where it 

 is connected with a brown spot which reaches the middle of the costa between the tips 

 of the 3rd and 4th veins : this band is cut obliquely below and covers the base of the 

 anal cell, the whole of the 2nd and of the ist basal cells and the bases of the discoidal 

 and of the ist posterior cells. Beyond the stigma there is a hyaline spot on the costa, 

 and two other smaller ones at the end of the 2nd vein and before the end of the 3rd. 

 The stigma is yellow, with a brown spot at the tip. Upon the posterior cross- vein is 

 a yellowish brown band which extends from the hind border to the middle of the first 

 posterior cell ; another smaller oblique brown band begins at the costal band in the 

 middle of the last portion of the 3rd vein and extends to the hind border, reaching 

 it after the end of 4th vein. On the middle of the third posterior cell is an uncertain 

 yellow longitudinal band, which extends anteriorly to the middle of the discal cell. 



A single male caught by Dr. Annandale at Paresnath, W. Bengal, 4400 ft., April 

 nth, 1909. 



15. Poecillis, n. gen. 



Very like the preceding, but distinguished by the complete chaetotaxy of the 

 head and the different pattern of the body. 



Head, antennae and frons exactly the same as in the preceding; no oc; or. 2. 

 4-5 ; the first superior very small ; the other bristles as in the preceding, but 

 those of the occipital row black; genal bristle strong, black. Thoracic and scutellar 

 chaetotaxy as in the preceding ; the abdomen also ; ovipositor flat, as long as the 3 

 last abdominal segments together. I^egs and wings as in the preceding genus, but the 

 pattern of the wings blackish, not yellow. 



Type : the following species. 



Notwithstanding the very different chaetotaxy of the head and the different 

 pattern of the body, it is very probable that this genus represents the female sex of 

 Chaetellipsis , and if this extraordinary sexual dimorphism should be proved, the 

 genus will retain this last name. Lagarosia , Wulp, is perhaps allied. 



35. Poecillis judicanda, n. sp. 2 . 

 (PI. ix, fig. 38). 



A black species with yellow and whitish markings, and with blackish pattern 

 of the wings. Length 7 mm., with the ovipositor. 



Head as in the preceding, but the pubescence of the frons dark and all the bristles 

 black ; antennae darker. Thorax shining black, with two broad reddish stripes 

 in the middle, which at the suture are so dilated as to reach the sides ; the whitish 

 yellow lateral stripe from the humeri to the hypopleura is very striking and below 

 this is a broad brown stripe ; sternopleura yellow beneath ; scutellum whitish yellow ; 

 metanotum without the median yellow stripe. Squamulae and haltères whitish 

 yellow. Abdomen black, the 2 basal segments yellow ; hind borders of 4th-6th 

 segments with a broad yellow band, which does not reach the sides. Ovipositor blacky
