embraces the end of the praefurca, the base of the fork of the 

 2nd vem, and the anterior cross- vein : the 2nd spot is in the 

 middle of the basal cell : the 3rd is placed across the middle of the 

 5th vein, tiius falling in both the 2nd basal and the anal cells. A 

 very pale grey, irregular, narrow but just distinctly perceptii)le 

 streak joins the fork of the 2nd vein to the fork of the 4th. In 

 addition there are some indistinct pale gre^^ spots placed appar- 

 ently irregularly in the basal half of the wing. Halteres 3'ellowish. 



Described from three a" cr and two 9 5 in the Indian Museum 

 collection, all captured by Dr. Annandale in the Simla district, 

 with the following data: Simla (7,000 ft.), io-v-09 (type o^ ) ; 

 Barogh (5,000 ft.), lo-v-io; Phagu (9,000 ft.), ii-v-09 (type 2 ). 



Types in Indian Museum. 



Notes. — This species must bear some resemblance to the 

 common European D. maculata, Mg. Of the descriptions available 

 to me that of this species is the only one in which the slight but 

 very distinct incrassation of the hind tibiae is mentioned. Yet 

 this character, although distinctly present in all five Oriental 

 species treated of here, and apparently common to both sexes, 

 has not, so far as I am aware, been described as generic, unless 

 indeed, Macquart is referring to this peculiarit}^ in his words 

 " jambes terminees par deux pointes, pen distinctes." 



In the European species, maculata , the thorax is described as 

 pale yellow, and there are stripes on the sides of the thorax, the 

 base of the wing is yellowish, and lesser differences also are appa- 

 rent between Meigen's species and the present one, which may be 

 regarded as distinct. 



Dixa maculipennis, mihi, sp. nov. 



cT' ? . Eastern and Western Himalayas. Long. 2-2^ mm. 



Head. — Back of head, vertex and frons light gxoy. Proboscis 

 yellowish, distinctly dark brown at base; palpi dark brown. 

 Antennae with two very distinct basal, (scapal) joints, the ist 

 circular, very short, the 2nd subglobular, both orange-yellow : 

 flagellum of at least 14 joints, possibly one or two more, if such 

 are shorter, as they are not at all easily counted. 



Thorax rather bright yellowish. Three dark brown thoracic 

 stripes as in the previous species ; and on each shoulder a distinct 

 but not sharply defined brownish, curved, transverse streak, 

 connecting the tip of the median stripe with the tip of the outer 

 stripe. Prothorax forming a sort of imperfect collar, swollen on 

 each side into an elongate lobe, lying close to the thorax. Scutellum 

 dark brown, with a broad yellow median indistinct stripe; meta- 

 notum dark brown. A small brown scutellar bridge with a 

 narrow yellow upper margin, joins the scutellum on each side to 

 the wing base. 



Ahdomen brownish, a small blackish mark towards each side 

 on the posterior margins, the segments becoming blackish towards
