Al'PKXDIX. 571 



annular, w itli yellowish tip ; flagelluni of apparently only five 

 yellowish joints ; palpi black. Thorax all black, except the 

 dorsuu), which is rich dark reddish brown, with a little sparse 

 short dark hair. Scutellum, metanotum, and sides of thorax 

 black. Abdomen dull black ; basal half or two-thirds of shining 

 lead-colour, much resemblinfr E. j^htmhiciucta, Brim. Genitalia 

 bright reddish orange. Ler/s : coxte black, femora yellowish 

 except for the narrowly black tips; remainder of legs dark brown, 

 tijis of joints just iierceptibly black. Legs apparently bare, owing 

 to the microscopic nature of the pubescence. Winr/s black, 

 axillary and spurious cells dark grey ; a roughly oblong clear spot, 

 with a distal triangular projection about its middle, placed 

 transversely at about three-fourths of the length of the basal cells, 

 extending across both of them ; a small circular white spot at 

 about two-thirds the length of the inner marginal cell ; a very 

 small apical white spot extending over the tips of both of the 

 submarginal cells and the 1st posterior cell. Five posterior cells j 

 the uppermost branch of the 4th vein forked ; anterior cross-vein 

 just before the middle of the discal cell; posterior cross-vein at 

 middle of discal cell. Halteres black. 



Length 12 millim. 



Described from a unique male from Ghumti, 4000 ft., Darjiling 

 district, vii. 1911 (F. U. Gravely). 



Ty~£ie in the Indian Museum. 



This species will come in my table between the two groups 

 containing (1) rujitliorax, Brun,, fenestrata, Brun., and scvteUata, 

 Edw. ; and (2) humherti, Os. Sac, and meleagris, Os. Sac. These 

 groups are distinguished for the sake of convenience by the 

 relative lengths of the species, the first being those of 15 to 20 

 millim. in length, the second those of 7 to 10 millim. long. 

 E. cingidata, being 12 millim. in length, is intermediate, but may 

 be distinguished from all these, except E. fenestrata, by the dorsum 

 only of the thorax being red instead of the whole thorax. From 

 fenestrata it is separated by having five, not four, posterior cells, 

 and by the presence of a small clear apical spot on the wiug. 



Eriocera nigerrima, sp. nov. 



2 . Head wholly blackish grey. Antennae black, with seven joints 

 to the flagellum ; palpi black, the joints rather thick and strongly 

 pubescent. Frons with a moderate-sized subvertical hump, and a 

 transverse protuberance below it. Thorax dark grey, \^ith three 

 black contiguous stripes of which the median one attains the front 

 margin ; shoulders moderately dark grey ; coUare distinct. Dark 

 grey pubescence about the shoulders, and a row of black hairs on 

 each side of the median stripe. Scutellum and metanotum black; 

 pleurae moderately dark greyish, with black and grey hairs. 

 Abdomen black above, almost dull and almost bare, unmarked ; 

 belly similar. Ovipositor bright reddish orange. Leys all black.
