them directly after Chrysops dispar in his Catalogue, but I can 

 see no differences sufficiently marked to justify them being made 

 distinct species. Chrysops impar, Osten Sacken believed to be 

 the same as the Wiedemann species, after seeing the type (see 

 Berlin. Ent. Zeit., xxvi, p. 97), an opinion with which I agree, having 

 also seen the type, which has the abdomen however entirely black 

 after the third segment, and the frontal callus is deeply incised 

 posteriorly a peculiarity I have not seen in any other specimens, 

 Ijut there are very few specimens in the collections I have had 

 access to, from Borneo, whence Rondani's came. 



The type of Chrysops hifasciata, Macquart, I have seen in the 

 Paris Museum and believe it to be a specimen of Chrysops dispar 

 though the black stripes on abdomen are of unusual length, ex- 

 tending to the end oF the abdomen, which I have not observed in 

 any other specimens from India or elsewhere. Macquart's type 

 is from Bengal. His description of the antennae is incorrect, 

 they are almost wholly yellowish, a little darker on the second 

 and third joints, not " black, red at the base." 



The species varies a little, chiefly in the colour of the scutelluvi 

 which ranges from reddish to reddish brown or nearly black. 

 The legs are usually testaceous or ^^ellowish but the posterior 

 femora are sometimes brownish or blackish, the coxae are also 

 darker in some specimens The forehead is greyish or yellowish. 

 The abdominal stripe beginning on the second segment is continued 

 to the base of the segment or to the base of the third and occa- 

 sionally reaches the fourth segment. It is an easily distinguished 

 species, with a 3'ellowish abdomen, the bifid stripe always distinct, 

 and a dark narrow band on the posterior border of the first segment. 

 The thorax in well-preserved specimens has golden yellow pubes 

 cence at the sides and base. The face and cheeks yellowish 

 brownish in the centre with the exception of a narrow yellow line 

 and with two black stripe-like spots on the lower part of cheeks. 

 Wings with a brow^n fore border and transverse band, chiefly 

 incised on its outer border. Length from 8 — n mm. 



In the British Museum are specimens from Ceylon (Yerbury, 

 Green) ; Nepal (Hardwicke bequest) ; Bangalore (Watson) ; Moul-

In Indian Museum coll, from Balighai, near Puri, Orissa; 

 Kulattupuzha, W. base of W. Ghats, Travancore ; Nedumangad, 

 ro miles N. E. of Trivandrum, Travancore ; Morapai, S. Bengal ; 

 Bukit Besar, Patani States, Siam ; I have also identified speci- 

 mens from Formosa. On one of the specimens from Ceylon Col. 

 Yerbury has the following note: " Common and generally distri- 

 buted. Torments cattle The scutellum and pilose stripe on the 

 pleurae in life bright gamboge yellow." 



[Flies of this common species conceal themselves during the 

 day on the lower surface of the leaves of shrubs, becoming active 

 towards evening. I found the species exceedingly common at Bali- 

 ghai in October.— N. Annandale.]
