fronto orbital, i vertical, i postvertical and r ocellar bristle. 

 Occiput blackish, eye margins with a row of strong bristles with 

 shorter ones behind them. Vertical triangle black, ocelli distinct. 

 A small dark brown oval mark on each side from eye margin to 

 base of antenna. I^ower part of head whitish; a row of strong 

 bristles on cheeks from back of head nearly to antennae. Anten- 

 nae yellowish, 2nd joint with a circlet of strong black bristles, and 

 additional ones ; 3rd joint with pale microscopic pubescence and 

 long black dorsal arista, yellowish at base. Proboscis rather long, 

 thick, pale, yellowish, the very small slender palpi at the middle, 

 with three or four long black bristles. 



Thorax dull brownish yellow, dorsum with four pale mauve 

 brown stripes, the two median ones continued to tip of the pale 

 yellow scutellum. Pleurae brownish ; 3 dorso-centralj 2 notopleural, 

 I pteropleural ; a basal and apical scutellar bristle. 



Abdomen^ ground colour dull brownish yellow with short pubes- 

 cence, but the hind margins of the segments broadly brown ; in fact 

 this colour covers most of the dorsum, leaving a central pale space 

 occupying most of the 2nd and 3rd segments. Belly yellowish. In 

 what I take to be the & specimen is a globular process at the tip 

 of the abdomen bearing two comparatively large conical protuber- 

 ances below. In the other specimen no genitalia are visible. 



Legs pale yellowish, microscopically bristly ; tarsi tips black- 

 ish; fore femora with a row of long bristles on upper, outer and 

 under sides ; subapical tibial bristle prominent. 



Wings pale brownish yellow, paler posteriorly; both cross 

 veins narrowly but distinctly suffused; halteres dirty yellowish, 

 knobs blackish. 



Described from two specimens in the Indian Museum taken be- 

 tween Kufri and Phagu, 2i-v-l6 (/Y, Annandale and S. Kemp). 



Both my irilineatus and the rather widely distributed Euro- 

 pean frontalis seem closely allied to the present species. The un 

 marked wing in the latter easily distinguishes it from trilineatus, 

 whilst frontalis possesses the rudiment of an additional cross-vein. 



Subfamily HELOMYZINAE. 



Helomyza unicolor, sp. nov. 



& 5 . vSimla. Long. 5 mm. 



9 . Wholly brownish 3^ellow, almost orange; lower part of 

 frons brighter, almost chrome yellow; upper part and vertex a 

 little deeper. Under side of head pale whitish yellow or yellowish. 

 Antennae deep orange, arista black, pale at extreme base, pubes- 

 cent, vSides of thorax paler ; pleurae with almost whitish reflec- 

 tions in certain lights. 



Abdomen with a blackish band on hind margin of all segments, 

 sometimes indistinct on 2nd segment, the band varying in intensity 

 and width, sometimes filling nearly all the apical segments; a row 

 of strong bristles on hind margin of each segment. The colour 

 of the abdomen varies to more brownish or to pinkish brown ;
