They agree very well witli Prof. ITendel's good descrip- 

 tion. Tiie back of tlic tliorax shows a more or less distinct 

 l)rown pattern, like that of the preceding species. 



The undescribed cJ is very li-ko the ? ; the abdomen is 

 of a reddisli-brown colour on the sides; the genitalia are 

 lounded, yellow, with a prominent strong spire forwards. 



'i'he wing ot tliis species is only 2'4 mm. broad ; tiie body 

 of the male measures only 6 mm. in length. 



4. Adapsilia opaca, sp. n., $ . 



Length of body 6 mm., of a wing 5*5 mm, ; breadth of a 

 wing 21 mm. 



Type in the Indian Museum : a single specimen from 

 Kangra Valley, 4.500 ft., Sikkim, ^-J {Dacirjeon). 



Nearly allied to the preceding species, but separated by 

 the shape of the third antennal joint and by the dull antero- 

 lateral portion of the frons. 



Head entirely of a pale yellow colour, whitish below on 

 the sides of occij)ut and on the face ; a black stripe on each 

 side on the lower edge of each antennal groove ; frontal stripe 

 brown ; the whole of the head is dull, e.\ce])ting the face, which 

 is very shining. Antennpe wholly reddish yellow, propor- 

 tionally short, the third joint being as long as the second, not 

 attenuated towards the end, wholly rectangular; arista bare. 

 Proboscis and palpi yellow, these last long and broad, black 

 pilose. Frons with parallel sides, as broad as the eye, tlat, 

 not prominent at the vertex ; frontal stripe clothed with 

 short black hairs, which extend also on the sides near the 

 base of the antenna). The m.'icrocliEetai are black and strong; 

 a frontorbital on each side ; the inner verticals are very long, 

 the outer short ; the ocellars are robust, the postverticals very 

 distinct. 



Thorax yellow, but viewed from before it appears to be 

 covered on the back by a white dust; there are on the back 

 four brown stripes, the middle ones approached and extended 

 to the neck, the outer broader but abbreviated before and 

 interrupted on the suture ; pleura) pale yellow, with a brown 

 vertical stripe on the fore part of mesopleura extending to 

 the sternopleura, which is entirely brown ; a small brown 

 spot on the pteropleura and on the hypopleura. The back is 

 clothed by short and dense black hairs, which on the pleura) 

 become longer ; the macrochaits are black and strong. 



Scutellum entirely pale yellow, clothed with black hairs 

 and provided with four long bristles on the border. Meso-
