194 Records of the Indian Museum, [Vol. Ill, 



Prothorax slightly longer than wide (length 7 mm., width 

 6 mm.), red and finel}' transversely rugulose above, with a long 

 black lateral stripe each side, more or less tending to be broken into 

 three spots. Second and third thoracic segments and abdomen of 

 a sordid reddish fulvous. 



Wings fumose, with partly hj^aline cells between the brown- 

 bordered costal cross-veins and with tw^o conspicuous hyaline bars 

 across the disc, bordered by areas of darker brown. These hyaline 

 bars cross the area traversed by the radial, median and cubital 

 veins ; the proximal bar is at the level of the base of the radial 

 sector and the second at the level of the first fork of the sector. 

 On the proximal side of the first bar three basal cells are more or 

 less hyaline, and on the distal side of the second bar are four small 

 hyaline spots in the next adjacent cells, the two anterior quadrate, 

 the two posterior smaller, linear, the three posterior, in line, and 

 out of line wath the first. 



Hind wing wdthout hj'aline spots, with veins of darker brow^n 

 all around the wdng-margin. 



Legs rufous beneath and basall}^, blackish superiorly and to- 

 wards the apex. The fore femora are darker than the others. 



The three Oriental species now made known in the genus, 

 which was so long supposed to be strictly American, may be 

 separated as follows : — 



a. Two teeth on the lateral mar- 

 gin of the head, and none 

 on the convex surface above 

 the hind angle: head red . . territans, Ndm. 

 aa. One tooth on the lateral mar- 

 gin at the hind angle of the 

 head on each side, and one 

 above this on the convex 

 surface. Head bicoloured. 

 Ik The darkest markings of the 

 fore wings comprised in a 



wide costal strip . . . . asiatica, Hardwicke, W. 



China. 

 bh. Darkest markmgs of the fore 

 wings are upon the cross- 

 veins of the wing disc . . onentalis, McL., Naga 



Hills, Assam. 



There remains also a fourth species, mentioned by McLachlan 

 in the Transactions of the Entomological Society of London for 1896, 

 p. 283, but not described, from Assam, which agrees with asiatica 

 and orientalis in the conformation of the hind angles of the head, and 

 not at all with territans. Probably good specimens of this species 

 will yet be found. 



Of other vSialidse, the collection includes four species of Neuro- 

 mus and one of Chauliodes : — Neuromus latrattis fromShillong, Khasi 

 Hills, Assam; N. infectus ^Mch., from Sikkim; A^. decemmaculatus,
