Menagerie at Schonbrunn, he had succeeded in breeding out the 

 oestrid of the Indian elephant {Cohholdia elephantis^ Cob.), which 

 was hitherto known only in the larval state. Since it is the inten- 

 tion of Prof. Brauer to furnish fuller details later in a special memoir, 

 he contents himself with giving the following short diagnosis of the 

 genus and species in the perfect condition : — 



Genus Cobboldia, Brauer. 



Head vesicular, with strongly projecting front. Antennae ex- 

 tremely prominent, owing to the large hatchet-shaped third joint, 

 with fine and bare arista. Beneath the antennae a very broad and 

 deep heart-shaped antennary pit, without a septum, extending to 

 the oral margin ; therefore the facial ridge very short between the 

 facial angles (" Yibrissenecken "). Oral cavity deep, the rudiment 

 of the proboscis fairly well developed, as in Cephenomyia, with 

 large claviform palpi. Face and cheeks shining, bearing tubercles 

 (" schwielig "). Ocelli present, eyes bare. Thoracic suture com- 

 plete. Wings large. Apical transverse vein present, posterior 

 transverse vein nearer to the angle of the third vein than to the 

 small transverse vein ; angle of the third vein V-shaped, without 

 projecting stump ; first posterior cell open. Alula of moderate size, 

 squamEe very large. Clavi and pulvilli moderately large. Legs 

 slender, short ; first tarsal joint as long as all the others put 

 together. Abdomen elongate, oval, in the male with forceps-shaped 

 hypopygium tucked under it ; in the female the ovipositor straight, 

 telescopic, chitinous, divided into four segments (when protruded 

 half as long as the body). Ventral plates triangular, separated 

 from the dorsal ones by a broad membrane. Fifth plate cleft in 

 the male. Macrochaetae absent. Hypopleurae with a row of hairs. 



Spec. Cohholdia elephantis, Cob. 



Gastrophilus elephantis, Cob. olim (from the larva), Trans. Linn. Soc. 



1831. 

 Cohholdia elephantis, Brauer (from the lana), Wien. ent. Z. 1887. 



Black, short and thickly clothed with hair ; head and antennae 

 reddish yellow ; proboscis and palpi black. Wings dark, blackish 

 blue, metallic ; basal cells, alulae, and squamae snow-white. Hal- 

 teres and legs black. On the head and on the margins of the 

 abdominal segments silvery white reflexions. In general appear- 

 ance resembling a Pharyncjomyia. Female with the front broader 

 and the ovipositor black ; otherwise precisely like the male. 



Length of body 12-14 millim. 



Length of wing 10-11 millim. 



The larvae leave the host in the early hours of the morning, 

 pupate in from one to two days, and the imago appears sixteen days 

 after the exit of the larvae. Copulation takes place immediately. —
