ened lower angle, and an intensely black spot on the upper angle. The hyaline portions 

 are of a whitish colour, but those on the hind margin are more greyish; axillar lobe 

 grey. 



Two female specimens, the type from Darjiling, 7000 ft., 27- v-io, caught by Mr. 

 Brunetti (^i|^) ; the other from Kurseong, 5000 ft., E. Himalayas, 8-vii-o8 (-f|~)- 



27. Tephrostola, n. gen. 



Distinguished from the preceding by the 4 scutellar bristles and from Acidia 

 by the bare third vein, the pale hairs of the thorax and the whitish bristles of the occi- 

 pital row. 



Head as in the preceding ; antennae very short, reaching the middle of the face, 

 the third joint rounded, a little longer than the second, with a pubescent arista ; 

 cheeks narrow ; oc. strong ; or. 2. 3 ; the genal bristles and those of the occipital row 

 are strong. 



Thoracic chaetotaxy complete, as in the preceding, the pale hairs of the thorax 

 well- developed ; scutellum with four bristles, those of the apical pair shorter and 

 crossed. Abdomen without bristles or with less developed apical bristles in the male ; 

 ovipositor flattened, long, triangular. Legs with a row of bristles on the front 

 femora, a single spur on the middle tibiae and the hind tibiae almost bare. 



Wings broad and short, with well developed and often double costal bristle ; wing 

 veins directed as in the preceding, but the cross- veins more or less approached, the 

 small one being always placed after the middle of the discal cell ; third vein bare. 

 Pattern of the wing like that of Aciitra. 



Type : Trypeta acrostacta, Wiedemann, 1824. 



It is ver)^ probable that some species of Acidia and Aciura belong here, having pale 

 pubescence on the thorax and whitish occipital bristles, as my African species caeca, 

 cyclopica and tephronota. It is also probable that the present genus is the same as 

 Platensina , Enderlein, igii. 



In the collection are 2 species of this genus, which ma}^ be distinguished as 

 follows: — 



1 (2). Thorax yellow at the sides : haltères and legs yellow ; wings with 



a hyaline spot at the tip between the ends of the 3rd and 4th 



longitudinal veins ; cross-veins less approximate. . . acrostacta, Wied. 



2 (i). Thorax black on the sides ; haltères and femora black ; wings 



without apical spot and with the cross-veins more approxi- 

 mate. . . . . . . . . . . reinhardi, Wied. 



56. Tephrostola acrostacta, Wiedemann. 

 (PI. X, fig. 57). 

 Wiedemann, Anal, entom., 54, 119 ITrypetal (1824) and Auss. Zweid., ii. 501, 39 [/rf.] (1830) ^ 

 guttata, Macquart, Mem. Soc. Lille, 1842, 387. i. pi. 31,. f. 10 [En^ina] (1843). 

 A black species, the thorax with dense grey pollen and with A^ellow sides, very 

 distinct by reason of the colouration of the cheeks in the male and the apical sj)ot of 

 the wings in both sexes.
