Head black, marked with a luteous, lateral, longitudinal streak con- 

 tinued to below the eyes; tirst joint of the antennae extending a little 

 beyond the apex of the scutellum, sordid piceous ; second joint nearly 

 one half longer than the first, linear, black, very slightly somewhat 

 capitulately thickened at the apex : rostrum nearly reaching beyond the 

 last pair of feet, luteous, here and there picescent, sparingly thinly 

 pilose, especially towards the apex, second joint a little longer than the 

 first, third joint shorter than the second, fourth longer than the third : 

 thorax above luteous-yellow, with a transverse basal band, more extended 

 forward in the middle, and a transverse streak placed a little before the 

 apex, black : scutellum black, marked on both sides at the base of the 

 horn with a lutescent spot, the scutellar horn as long as the thorax, 

 erect, only very slightly curved, black, picescent near the apex, which is 

 horizontally truncate : femora nodulose, piceous-luteous, sprinkled black, 

 first pair, near the base, with a pale-yellowish ring : tibiae clothed with 

 slight, somewhat hispid, pile, luteous, spotted black : tarsi black : basal 

 part of abdomen sub-virescent, whitish, apical part black, the pale colour 

 of the venter extends from the base to the apex of the penultimate ventral 

 segment, the last ventral segment and the genitalia are black ; the black 

 colour of the dorsum of the abdomen is more extended towards the base 

 especially in the middle of the segments : hemelytra cinereous-hyaline, 

 except the base, which is yellow whitish : veins and the narrow cuneus, 

 piceous : wings cinerescent. Long, 5mill. ; cum hemel, 8 m. Hab.

This species was found amongst a number of Dispkinctus humeralis, 

 Walker, sent by me to Dr. Bergroth for identification. All were 

 collected on the Cinchona plantations at Mungphu in Sikkim by Mr. 

 Gammie, where this species was found on Cinchona calisaya, and occasion- 

 ally on Cinchona succirubra. It has not occurred yet in sufficient numbers 

 to do much damage; but as it belongs to the same genus as the destruc- 

 tive ' Mosquito pest' of the tea, its operations should be carefully watched. 

 H. febriculosa is allied to H. tkeivora, Waterh., but is distinguished 

 by the erect, very little curved scutellar horn ; in H. theivora, ? , the horn 

 is much curved : this difference, however, appears to be merely of 

 varietal importance.
