212 Records of the Indian Museum. [Vol. III. 



Atherix labiata, Big, 



A & in my collection from Maskeliya, Ceylon, taken in March, 

 agrees well enough with Bigot's description for me to have little 

 doubt of its identity with his species. The pale basal third of the 

 hind femora differentiates this species from all other Oriental ones. 



Chrysopiius ornatipennis, mihi, sp. nov. 

 9 . South India. I.,ong, 4 mm. 



Head. — Frons blackish grey, grooved down the centre, one- 

 fourth of width of head, only slightly wider towards vertex ; ocelli 

 on subtriangular, concolorous, slightly elevated triangle, black, with 

 a narrow, pale border, and a few microscopic bristles. Antennae, 

 1st and 2nd joints livid brown, 3rd with greyish pubescence, bristle 

 very long. Proboscis shining, livid brown at base, bright yellow on 

 narrow part, with two very minute dark brown hairy lamellae. 

 Back of head yellowish gre}^ above, bluish grey below, with numer- 

 ous minute black bristles, especially towards the vertex. 



Thorax 5^ellowish brown, the dorsum covered with microscopic 

 scales, which, seen from behind, are hrilliantly emerald-green on the 

 centre and bright blue towards the sides, the posterior part and over 

 the whole of the scutellum. In addition to the scales the entire 

 surface of the thorax and the scutellum is covered with long curved 

 bristly hairs. Sides of thorax uniformly shining tawny yellow. 



Abdomen brownish, becoming 3^ellow on posterior border, 

 covered on entire upper surface rather closely with soft black hairs, 

 which extend round the sides and are very short on the yellow 

 belly ; they are rather thicker and longer on the fore corners of the 

 abdomen. The 5th segment is much reduced in size, blackish 

 grey ; 6th and 7th st5date, blackish grey with a broad, distinct, pale 

 yellow posterior bord:-r, supplemented by a long, thick, cylindrical 

 blackish grey ovipositor. 



Legs. — Coxce and femora bright tawny yellow, tibiae pale 

 brown, tarsi black ; coxae with some bristh^ hair on and around 

 them, hind pair with a black streak on apical border ; middle and 

 hind tibiae with two short yellow spines at extreme tip. 



Wings pale blackish grey, posterior part nearh' clear, light 

 grey or nearly clear in the following places : distal ends of basal 

 cells ; middle of anal cell ; a rather narrow pale yellowish band 

 from the middle of the fore border (adjacent to the black stigma) 

 to the distal end of the discal cell, thence becoming pale grey ; a 

 yellowish grey diffused spot just beyond (and contiguous to) the 

 stigma. All the cells below the 3rd longitudinal vein are pale grey 

 or clear in their centres The upper branch of the third vein bears 

 a small appendix at the bend, which is rectangular. The inner 

 cross-vein is placed at one-third of the discal cell, and the two 

 forks of the upper branch of the fourth vein spring almost simul- 

 taneously from the upper corner of the discal cell. Halteres pale 

 vellow.
