new Oriental Homoptera. 737 



In some specimens the fuscous apical area to the tegmina 

 is almost obliterated, but the veins there are then distinctly 

 infuscated. 



Oliarus simlcej sp. n. 



Body above black, margins of vertex and pronotum, 

 lateral margins and central-longitudinal ridges to mesonotum, 

 and posterior segmental margins to abdomen ochraceous ; 

 face black, about posterior half, the lateral margins, and the 

 central carination ochraceous ; body beneath and legs black 

 or piceous; rostrum (excluding apex), base of abdomen, 

 posterior segmental margins, tibiae, tarsi, and apices of 

 femora more or less ochraceous ; tegmina and wings hyaline, 

 the former with more than half of the venation dull ochra- 

 ceous, somewhat thickly covered with longiy setose granules, 

 veins of the apical area mostly black, stigma elong;ite, black ; 

 vertex elongate, distinctly longer than broad, its lateral 

 margins strongly elevated ; mesonotum with five central 

 ridges; face nearly twice as long as broad, the central and 

 lateral ridges acute ; tegmina about three times as long as 

 broad. 



Long., excl. tegm., 5i mm. ; exp. tegm. 14 mm. 



Hub. Simla (Brit. Mus.). 



Allied to 0. caudatus, Walk., but differing principally by 

 the narrower and longer face and vertex. 



Oliarus kurseotigensis, sp. n. 



Closely allied in general appearance to the preceding 

 species, 0. simh^, but differing in the broader vertex (in that 

 respect more like 0. caudatus, Walk.), the narrower and 

 black face, the central ridge and lateral margins of which are 

 alone testaceous, and in the two discal transverse veins of 

 the tegmina situate almost in a line with the commence- 

 ment of the stigma, being both almost perpendicular and in 

 a line with one another, not angulated as in O. simlw, and 

 more especially by a perfectly straight and continuous 

 transverse vein on the disk of the apical area a little before 

 the bases of the apical cells. 



Long., excl. tegm., 4^ mm. ; exp. tegm. 12-12^ mm. 



IJab. E. Himalayas; Kurseong (Ind. Mus.). 



Oliarus nuivaroi, sp. n. 



Resembling the two previous species, 0. stmlce and 

 0. kurseongensis, in general appearance, but differing in the 

 following structural characters : — Vertex longer than broac1_,
