igoQ-] Records of the Indian Museum. 429 



Described from a specimen in fairly good condition in the Indian 

 Museum collection from Margherita (middle pair of legs wanting, 

 but are probably coloured like the rest). Quite a distinct species 

 from all others except marmoratus. 



N.B. — Walker's guttipennis must be near this species, but 

 appears distinct, and is larger. 



C, marmoratus, mihi, sp. nov. 



(Leptis marmorata, Bigot, nam. nud.) 

 (Plate xii, fig. 10, wing.) 



cf . Assam. Long. 4 mm. 



Head.- — Vertex much elevated, light brown, the ocelli well 

 separated and very distinct, semi-transparent, with black centres. 

 Eyes light chestnut-brown, upper facets rather large, lower ones 

 very small and much darker brown. Eyes contiguous almost 

 down to the antennae, the frons receding so much as to be invisible ; 

 the inner sides of the eyes (seen from in front), also the face below 

 the antennae, blackish grey. Antennae, proboscis and palpi brown- 

 ish yellow. 



Thorax. — Moderately dark brown, with sparse gold-yellow 

 hairs on dorsum ; slightly paler at sides, and with concolorous 

 scutellum and metanotum, the former bearing some moderately 

 long brownish hairs. 



Abdomen. — Dark brown ; second segment, and posterior border 

 of first segment lighter. Belly brown. Whole abdomen lightly 

 covered with brownish hairs. 



Legs. — Coxae light brown. The single leg of the (unique) type 

 (fore leg) is concolorous. 



Wings. — Rather dark brown, with pale grey spots, of which 

 the clearest is an oval one just beyond the stigma, reaching from 

 the costa to the fork of the third longitudinal vein. Below this 

 spot, follows a spot in each of the first, second and third posterior 

 cells. There is a small one in the centre of the discal cell, which, 

 with a small one in the fourth posterior cell and a large one in 

 the fifth posterior cell, form a row. A small spot is at the 

 tip of the marginal cell, and a larger one at the tip of the sub- 

 marginal ; whilst the whole posterior border of the wing is pale 

 grey, spreading out somewhat in the cells and in the axillary cell.: 

 The veinlets forming the upper fork of the fourth longitudi- 

 nal vein emerge practically together from the upper corner of the 

 discal cell, the outer side of which is practically quite straight 

 Halteres light brown with large blackish brown knobs. > , v 



Described from one specimen from Sadiya in the Indian^ 

 Museum collection in fairly good condition, except for the 

 absence of nearly all the legs. I, however, do not hesitate to 

 describe it, as it shows by its mottled wings its distinction from 

 all other Eastern species except albopictus. ;
