about as loug as thorax and scutellum togethei*, as wide at 

 base as widest part of thorax ; oblongo-conical, moderately arched, 

 composed of four obvious segments of about equal length, with 

 apparently a hidden 5th segment in d" (apart from the genitalia, 

 which are concealed) and a definite 5th segment in $ . Legs of 

 moderate size and rather slender. Wings transversely wrinkled ; 

 auxiliary vein ending at about middle of wing; 1st, 2nd and 

 3rd veins ending at about equal distances from each other, the 

 latter a little before the wing-tip; ]st posterior cell open; 

 anterior cross-vein at a little before middle of discal cell, 

 and much before tip of auxiliary v'ein ; 5th vein running weakly 

 to wing-margin; 2nd basal cell and anal cell subequal, both very 

 short ; 6th and 7th veins distinct, not reaching wing-margin. 

 Alulae large, conspicuous, alar squamae comparatively small ; 

 thoracic squamse very much larger, wrinkled. 



The above is partly abbreviated from the very voluminous 

 description by Brauer, and partly drawn from a S and $ in the 

 British Museum. 



Life-history. Bred from larvae from the alimentary canal of the 

 Indian elephant. 



Range. India (C. elepJianiis) : probably also Afi'ica, as larvae 

 of one or two species, the adults of which are not known, but 

 which are believed to belong to this genus, have been found in the 

 African elephant (for references, see Ban, ' Genera Insectorum,' 

 Fascie. 13, p. 9).

S $ . Head neaidy as broad as thorax, prominent in front ; 

 frons and face receding gradually, both with nearly parallel sides, 

 about half the width of the head ; bright red-orange, bare except 

 for a few fine hairs at sides of frons ; at vertex barely above level 

 of eyes : with some whitish reflections on head generally ; ocellar 

 triangle small, black, placed on extreme vertex, with a little short 

 black hair; ocelli dull orange, small and inconspicuous. Antennae 

 wholly bright red-orange, 1st joint extremelv short, annular, 

 almost hidden by anterior margin of frons, 2nd approximately 

 cup-shaped but with irregular outline, 3rd oval, about 14 times as 

 long as broad, with a rather short, black, basal arista, which is 

 orange at the base. Foveae very deep, pale yellow. Mouth- 

 opening and the shining proboscis black. There are some short 

 black hairs on the lower part of the head. Occiput black, with 

 short black bristly hairs, a little orange behind vertex and on
