CYFHOMYIA. 57 



2. First antennal joint three or more 



times longer than 2nd STBATIOMYIA, Geoff., p. 58. 



First antennal joint less than three 

 times as long as 2nd, generally 

 much less ODONTOMYIA, Mg., p. 61. 



The above distinctions are purely arbitrary, but each genus has a 

 facies peculiarly its own, which the student will soon recognise. 



Genus CYPHOMYIA, Wied. 

 Cypliomyia, Wiedemann, Zool. Mag. i, p. 3.(1819). 



GENOTYPE, C. auriftamma, "Wied. (Tropical America); designated 

 by Brauer, 1882. 



Head as broad as thorax, semicircular ; eyes bare (occasionally 

 just perceptibly hairy), in J closely contiguous for a considerable 

 distance ; frons in rather broad, sides approximately parallel ; 

 postocular orbits in $ broad. Antennae with 1st joint moderately 

 long, broader at tip; ind cup-shaped, half as long as 1st; 3rd 

 cylindrical, tapering, of eight subequal annulations, practically 

 bare. Thorax considerably elongate, much narrowed in front, 

 moderately arched, anterior corners rather angular; in many 

 species with three lighter longitudinal stripes. Scutellum rather 

 large, broader than long, trape/oidal, with two spines that are 

 longer and more divergent in d than $ . Abdomen subglobular, 

 thick, about as long as thorax, 5-segmented ; 1st segment very 

 short, mostly hidden by scutellum. A generic peculiarity is the 

 presence of hair-spots towards the sides of the last segment, 

 placed on its anterior margin. Legs rather long, especially the 

 femora, simple, slender ; tarsi generally longer than tibiae. Wings 

 fully developed, considerably longer than abdomen and folded over 

 it when ab rest. 



Range. North, Central and South America, South Africa, India, 

 Sumatra. 



29. Cyphomyia indica, sp. nov. 



Head wholly bright orange, bare, including the thick postocular 

 orbits, which are distinctly demarcated from the vertex by a 

 narrow groove ; frons about one-third width of head, barel) r 

 broader at vertex ; underside of head with a little short white 

 pubescence towards the eye-margins ; eves and proboscis black. 

 Antennae with 1st and 2nd joints dark reddish brown, 3rd black, 

 with eight distinct annulations, three times as long as 1st and 2nd 

 together. Thorax deep black, with rather dense short grey and 

 brownish-grey pubescence, which is a little longer and more 

 whitish posteriorly and on the concolorous, rather large, nearly 

 oblong scutellum ; spines of latter tipped with brown ; pleurae 

 blackish with a little whitish pubescence. Abdomen much broader 

 than thorax, nearly circular, brilliantly shining violet-blue, with 

 very short whitish pubescence; venter similar. Legs black, with 

 whitish pubescence ; knees barely perceptibly brownish orange ;
