106 PERCY SLADEN TRUST EXPEDITION 



the end of the third thin veins, the hypopygium is different, bears a long dark anal 

 process and is without the long curved hairs ; the hind tarsi are not so stout. 



Can this be the male of C. kiboshoensis Brues described from a single female collected 

 at Kibosho, German East Africa ?

 (Plate 5, fig. 1.) 



$. Agreeing with Bigot's description of the female to which may be added that the 

 frons is dark brownish-black slightly shining, arista microscopically pubescent, palpi 

 bearing 4 — 5 bristles at the tip only. 



Thorax reddish-brown to brownish-black, scutellum very wide and short with one 

 strong bristle and one minute hair each side near the base, prothorax with one strong 

 bristle pointing up to the humerus, mesopleura running into the humerus without any 

 appreciable suture except for the prothoracic stigma and bearing the same pubescence 

 along its upper half as is borne by the humerus. 



Abdomen with the first two segments reddish-yellow, the hind margins dull blackish, 

 wider on the second than on the first segment, and almost interrupted at the middle ; the 

 third to fifth segments are dull black with a triangular reddish-yellow mark on the base of 

 each segment, the apex of the triangle almost reaching the hind margin ; sixth segment 

 somewhat longer, broadly yellowish on the base and dull black on the hind margin ; the 

 hypopygium is hidden when viewed from above but projects considerably below ; the long 

 yellow anal organ arises from out of a short yellow cup-like process just beneath the hind 

 margin of the sixth segment. 



Legs with the hind femora bearing beneath at the extreme base on the side nearest 

 the abdomen a little clump of about 3 — 5 short stout black bristles ; hind tibiee bare 

 except at the extreme tip, where there is on the upper side one short bristle and beneath 

 one long and 2 — 3 short spurs. 



Wings with the costa reaching quite to middle of wing, ciliation extremely short and 

 fine, only an indication of a mediastinal vein, subcostal ending close to the cubital which 

 is forked, the fork being very acute (fig. 1). 



%. The three female specimens in Bigot's Collection are in bad condition, being 

 immature, gummed to slips of talc, and have every appearance of having been originally 

 preserved in spirit ; they each bear a label, " Phora Cotesi ex larva Tachinidarum parasit. 

 Seric. mori — n. sp. Calcutta J. B.", and there can be little doubt are the type specimens. 

 Bigot having on other occasions omitted to re-label his type specimens with the name he 

 ultimately gave the species when describing it. These specimens agree so accurately 

 with the Seychelles males in the exceedingly short costal ciliation, in the relative positions 

 of the ends of subcostal and cubital veins, in the absence of any bristle or ciliation to the 

 hind tibiae above (only differing in the sexual characters of an elongate proboscis, simple 

 hind femora, and differently shaped and coloured abdomen), that I do not hesitate in 

 considering them sexes of the same species.
