cell with 4 subhyaline spots placed along the hind margin of the wing. The grey 

 hind portion of the wing shows two rows of larger and more hyaline spots. 



A single female specimen from Dharampur, 5000 ft., Simla Hills, 14-V-08

 {A.D. Imms). 



29 Craspcdoxantha, n. gen. 



Easily distinguished from the preceding genera by its entirely yellow body, black 

 spotted thorax and hyaline wings with yellow longitudinal rays. 



Head as high as broad ; frons and epistome a little prominent ; face concave, very 

 short, the narrow cheeks appearing therefore to be produced below ; mouth opening 

 very broad ; proboscis short, palpi bristly ; antennae inserted toward the middle of 

 the eyes, rather long, reaching the epistome, the third joint rounded at tip, pubescent, 

 i^ times as long as the second, which is rather elongate ; arista with microscopic 

 pubescence. Oc. strong; or. i. 3, accompanied by a row of short hairs on the eye 

 margin ; pvt. parallel ; bristles of the occipital row all yellow, but neither long nor 

 thick, pointed ; genal bristle strong. 



Thorax with yellow pubescence and complete chaetotaxy ; scutellum with 4 

 bristles, those of the apical pair touching at the end. i\bdomen contracted towards 

 the base, with short but abundant lateral bristles ; ovipositor flattened, broad, short. 

 Legs short and robust ; front femora with a row. of very strong bristles ; middle tibiae 

 with a single spur ; hind tibiae with a very developed row of short equidistant bristles. 



Wings long and narrow, with a short but distinct costal bristle. Stigma long ; 

 first vein long, reaching the small cross- vein ; 2nd long, straight ; third bare, strongly 

 curved below towards the end, the first posterior cell being therefore narrowed at the 

 end ; 4th almost straight ; small cross- vein placed after the middle of the discal cell, 

 perpendicular, not much approached to the hind cross-vein, which is oblique ; inferior 

 angle of the anal cell drawn out into a narrow and long point, longer than the second 

 basal cell. Wing-pattern consisting of yellow longitudinal rays, one of which is placed 

 along the fore border. 



Type : the following new species. 



This genus seems to be allied to Xanthorrhachis in the group Acidia, but is placed 

 here on account of the pale pubescence of the thorax. In the pattern of the wings it 

 approaches the American genus Xanthacrona, which belongs to the Pterocallinae in the 

 family Ortalidae. The resemblance between this and the preceding genus and the 

 American Pterocallinae, which show perhaps natural affinity, is very notable. The 

 Trypeta marginalis of Wiedemann, from Cape of Good Hope, in all probability belongs 

 here. 



59. Craspcdoxantha octopunctata, n. sp. 9 . 

 (PI. X, fig. 59)- 



A handsome yellow species, with 8 black dots on the thorax, a broad yellow 

 border along the whole fore margin of the wing and a yellow ray along the 5th vein. 

 Length 6 mm:, including the ovipositor, which measures i| mm.
