APHIOCHATA FERRUGINEA BRUNETTI 
Aphiocheta ferruginea was described by Brunetti.(388)  Al- 
though the flies were accidentally reared from a dead lizard in 
1907, the description was not published until 1912. Brunetti 
describes this species at length as he found it to correspond with 
some specimens of flies at the Indian Museum sent there by 
Doctor Crombie, obtained from the feces of a European in 
Rangoon suffering with myiasis. In the feces were passed 
eggs and maggots as well as adult flies. 
According to Brunetti A. ferruginea has a wide distribution 
throughout the tropical regions and some adjacent parts of the 
temperate zone, also. 
Brunetti’s description is as follows: 
6 2. India, Ceylon. Long. 24-3 mm. 
Head.—Brownish yellow, yellowish, often more or less tinged with grey, 
sometimes entirely greyish. Eyes black, microscopically pubescent, poste- 
rior orbit with a row of short black bristles; two strong macrochaetae 
below the lower angle of each eye, and a vertical row of short bristles 
on the cheeks. Antennae pale yellowish, varying to brownish yellow, 
arista long and microscopically pubescent. Palpi brownish yellow or 
yellowish, with several shorter bristles on outer side, a few hairs on inner 
side and five or six separated strong spines towards the tip. Frons 
generally concolorous but sometimes with brownish irregular marks in 
the middle on a yellowish ground colour, the vertical impressed line 
sometimes very distinct. The frons is furnished with four rows of four 
macrochaetae each. The upper or vertical row are reclinate, equidistant,
