224 MYIASIS 



mammilliform process. The two mandibles, which project ventrally, are very thick, 

 curved and black, there being apparently a serrated basal plate to each one. The 

 first segment has on the dorsum short brown thorn-like spines on the anterior moiety, 

 the posterior area being nude, and there are also two lateral pairs of short papillre. At 

 the base of this segment is noticed a small reddish-brown spot on each side ; the 

 second and third segments have short dark spines on their anterior moieties, 

 especially pronounced on the second ; the third, fourth, fifth and sixth segments have 

 many similar spines all over them, the seventh has very much smaller, paler and 

 scanty ones, the eighth and ninth have none. The anal segment bears two groups 

 of spiracles, arranged three in a group ; these are all curved, the two outer ones 

 outwards, the middle curved towards the outer one ; spiracular areas brown. The 

 segments are deeply constricted and the spines are particularly prominent on the 

 lateral borders. Ventrally the larva is spiny just as it is dorsally. 



" The piipari Hill, according to Fuller, is stout and oval, dark purple in colour, and 

 as a rule covered with a mealy down." 



" Fuller mentions that it is averred that the flies lay their 

 eggs upon bedding. The sharp ovipositor seems to point to their 

 being able to lay their eggs directly in the skin. The eggs when 

 laid in the former position hatch out rapidly, and the larvje bury 

 themselves under the skin. They at first produce a boil or 

 swelling which leads to inflammation, which becomes most painful 

 owing to the accumulation of excreta and the rasping movements 

 of the spiny maggot." " In the majority of cases. Fuller states, 

 the scalp seems to be the part most subject to invasion, but the 

 larvae are found in other parts of the body." " Fuller was 

 informed by a correspondent that he ' noticed a maggot fly in his 

 tent on the Tuesday of one week, and on the following Saturday 

 suffered from an itching in the arm and chest. On Monday the 

 spots had taken the form of blind boils, with a black speck in the 

 centre of each. A week later maggots measuring one-third of 

 an inch were expressed from the boils. The fly observed was 

 caught and living maggots extruded from the abdomen when 

 squeezed.' " 



" The adult fly is very sluggish in nature and does not move 

 about on windy days. Pupation takes place on the ground just 

 as in the QLstridai. Besides man, Bengalia depressa attacks dogs, 

 rabbits and other animals." 



Austen (1908, p. 24), however, makes the following statement : 

 " Within the last few years C. aiitliropophaga has been wrongly 

 identified as Bengalia depressa Walk., under which name it is 

 frequently referred to in reports on ' Economic Zoology " and
