MONGOMIOIDES. 483 



Kangoon, 25. ii.08 (all Annandale) ; Sylhet, 5. ii. 05 (Lt.-Col. 

 Hall). 



Types originally in Dr. Trentepohl's and Wiedemann's collec- 

 tions, presumably now in the Vienna Museum. 



This species is likely to prove to have an extensive distribution 

 in the East, and is probably fairly common in Bengal and the 

 south-eastern parts of India. The clouded wing-tip makes it easily 

 recognisable from all other species in this group. 



347. Mongomioides marmorata, sp. nov. (PI. IX, fig. 11.) 



5 . Head black ; eyes contiguous, face black ; proboscis, antennae, 

 and palpi yellowish ; back of head with few hairs. Thorax yel- 

 lowish, practically bare ; dorsum more orange, with traces of a 

 median dark line on anterior part. Scutellum and metanotum 

 apparently concolorous (damaged by pin). Abdomen yellowish 

 brown, dorsum with a tendency to dark marks; minutely pubescent. 

 Grenitalia very large, yellow, hairy ; consisting of upper and lower 

 halves, the lower terminating in a sheath, the upper in a two- 

 bladed, rather short, stiff ovipositor. Legs uniformly pale yellow. 

 Wings pale grey, with lighter spaces ; the fore border shows four 

 such, of which the first reaches to the posterior border at the end 

 of the 7th vein ; the second extends to the basal part of the mar- 

 ginal cell ; the third reaches the submarginal cell ; and the fourth, 

 a smaller one, is towards the end of the wing ; the base of the 

 wing and the 3rd posterior cell are also nearly clear. Venation 

 as in trentepohlii, Wied. Halteres brown, stem pale yellow. 



Length 4 millim. 



Described from a unique specimen, Calcutta, 28. xi. 07, in the 

 Indian Museum collection. 



348. Mongomioides nigroapicalis, sp. nov. (PI. IX, fig. 12.) 



rf . Head blackish grey ; back of head brownish yellow. Pro- 

 boscis brownish yellow ; palpi comparatively long and stout, dark 

 brown, nearly black, pubescent. Antennas brownish yellow, 

 scapal joints large, remainder oval, pubescent. Thorax: neck

 bright yellow, rather broadly black at the tips ; tibiae very pale 

 yellowish white, very narrowly black at the tips ; tips of tarsi 

 blackish. Wings elongate, practically clear, unmarked. Auxiliary 

 vein ending at middle of wing, the 1st longitudinal a little 

 beyond ; the 2nd longitudinal beginning before the middle of 

 the wing, rather widely bisinuate, forked at a little beyond its 

 middle, the upper branch short and nearly perpendicular, as
