CEPKALOMTIA. — COBBOLDIA. UUl 



as stated in generic diagnosis, upturned apical part of 4th vein 

 closing 1st posterior cell, strongly bisinuate and narrowly or 

 deeply suffused, the colour extending to the tips of the 2nd and 

 3rd veins and the costa ; anterior cross-vein narrowly suffused ; a 

 minute bhack dot at the tip of the vein which closes the discal 

 cell. 



Length, 8 mm. 



Described from one specimen in the Pusa collection, from the 

 nostrils of a camel at Sohawa, x. 1913. One J and two $ $ in 

 the British Museum, bred from larvce sneezed from the nostrils of 

 a Bactrian camel in the Zoological Gardens, Regent's Park, agree 

 very closely, but have the frons and upper part of the head more 

 orange. For distribution see under the genus. 



Some very interesting notes on this species as a parasite of the 

 camel are given by Col. Terbury and Col. Nurse (Journal Bombay 

 Nat. Hist. Soc. xiii, p. 683 ; xiv, p. 009 respectively). Tiie larvae 

 when about full grown are squeezed out of the nostrils by the 

 camel, usually in February or March, and they then pupate in 

 the ground. They may easily be bred in small pots or similar 

 receptacles with a few inches of earth, sawdust or leaves, the 

 emergence of the imago occurring about ten days after pupation. 

 Larvae of this species are not uncommon at stations where camels 

 are numerous, but the adult lly seems to be only very rarely seen 

 in a wild state. It has been bred by Col. Yerbury at Aden and 

 by Col. Nurse at Quetta. 



Genus COBBOLDIA. Brauer. 



Cobboldia, Brauer, Denkschr. Ak. Wiss. Wien, Ixiv, p. 262, pi., 

 tigs. 1-18 (1897). 



Head nearly as broad as thorax. Eyes rather small, bare, with 

 all facets of uniform size, small, Frons in both sexes broad, 

 linear, nearly half the width of the head in S , over half in $ , 

 flush with eyes on vertex, flat, very large and prominent in front, 

 sloping gradually to base of antennae. Head in prolile descending 

 below eyes for a distance equal to about half their length ; face 

 restricted almost to the cheeks through the extraordinary size and 

 depth of the fovea;. Antennas set below the slightly projecting 

 front margin of the frons ; 1st joint very small, apparently 

 annular; 2nd moderately large, irregularly cup-shaped but with 

 the margin forming three distinct lobes; 3rd joint large, com- 

 paratively thick, oval ; arista bar« ; ])roboscis short, cylindrical, 

 with the sides of the groove fused together at the base, produced 

 at the apex above into a stylet-like upper lip, to which the semi- 

 circular labella flt closely beneath. Occiput iu)t extendeil behind 

 eyes in profile. The whole head is bare except for a little soft 

 pubescence on the vertex and on the under side, and a few Hne 

 hairs on the frons. Thorax almost broader tiian long, slightly 

 arched, slightly narrower in front, with anterior corners rather 

 angular; scutelluni semicircular, of moderate size. Abdomen
