MACHOCERA. 53 



The example representing what I take to be the female of 

 this species agrees with the male in every way except in the 

 abdomen and its greater size. 



3. Macrocera flavicosta, sp. nov. (PI. I, fig. 3.) 



$ . Head blackish, except pale proboscis and palpi. Antennae 

 missing, except scapal (yellowish) joints. Eyes with short white 

 pubescence. Thorax (slightly damaged), brownish yellow, with 

 two lateral broad black stripes not reaching the shoulders, and 

 three median narrower ones attaining the front margin. Scutellum 

 and metanotum -brown, the former with bristles on the hind 

 border. Sides of thorax yellowish, including humeri, pleurae 

 brown, moderately shining. Various short bristles on the thorax 

 and four or five strong post-alar ones. Abdomen black, hind borders 

 of each segment with a narrow yellow band ; genitalia small, black. 

 Legs with the coxae and femora yellowish, tibiae and tarsi dark 

 brown. Wings pale grey, hind border and along the veins here 

 and there very faintly darker ; anterior part from costa to behind 

 the 3rd vein yellow, with ill-defined brown marks as follows: 

 at base on the costa ; a larger one from the costa up to and 

 including the fork of the 4th vein ; smaller ones over fork of 3rd 

 vein and at tip of wing ; also a narrow brown line along the 

 hinder margin of the yellow part ; also between 5th and 6th 

 veins just below coalescence of 3rd and 4th, and along the 

 greater part of 6th vein. Halteres brownish yellow. 



Length 6| rnillim. 



Described from one example in my collection, without exact data, 

 but certainly captured by me in the East, most probably in India. 

 In good condition except for the missing antennse and the little 

 damage done to the thorax by the pin.
