ORDER DIPTERA: SCHIZOPHORA: THE MUSCOIDEA 155 



yuwa = fly). One species has been described, A. luteola, from 

 Tropical Africa. It resembles a blow-fly in everything but 

 colour, which is a dirty yellowish-brown with the after part 

 of the abdomen rusty black. The female is easily recognised 

 by the great length of the 2nd abdominal segment. The 

 larva, which is known as the Congo Floor Maggot, lives in 

 the mud floor of native huts and comes out at night to suck 

 the blood of people sleeping on the ground. It differs from 

 other Muscid maggots in being somewhat broader and flatter, 

 and in its much more wrinkled surface (Fig. 55).

Genus Cordylobia {KopSv\>j = a bump, or tumour ; /3t'o9 = way 

 of life). This genus, of which three species have been 

 described, is also peculiar to Africa. The notorious species 

 is Cordylobia anthropophaga, Griinberg (the Tumbu-fly), the 

 larva of which is a subcutaneous parasite of man and other

animals in many parts of Africa. The adult fly is very much 

 like Auchnieromyia luteola, but in the male the eyes are set 

 close together, and in the female the 2nd abdominal segment 

 is not of any remarkable length. The maggot (Tumbu, 

 Fig. 56) is plumper and more barrel-shaped than other 

 Muscid maggots and is more or less completely covered with 

 small spines which are grouped in twos and threes, and the 

 breathing-slits of the stigmata on the last segment of the 

 body are of a very peculiar shape (Fig. 56). The presence 

 of the maggot occasions the formation of a boil, in the centre 

 of which there is an opening through which the maggot
