A422 Records of the Indian Museum. [Vor. Vil, 
almost obsolete; second arched; second marginal cell triangular, 
larger; radial cell short; cubital petiole almost twice as long as 
discoidal subcosta; clavus long, large. Hind wings veined less 
distinctly than forewings but very similarly, except radial cell 
wanting. 
Abdomen short, thick. Male—Claspers curved forward, 
subacute, moderately long; anal valve erect, large, with short 
rounded lobe projecting caudad, truncate above, with anal 
opening distinct. Hemale--Genital segment short, large and 
subglobose at base, produced into two short, needle-like processes 
with a bivalve ovipositor between, exserted. 
Redescribed from two pairs (“‘ type material’’) from Dehra 
Dun, West Himalayas, and seven males and nine females from 
Bettiah, Champaran, Bengal. from galls on mango shoots; one 
male from Dehra Dun in mango gall. Buckton described this 
species as a Psylla, but, of course, it is widely different from the 
members of that genus. 
Eurhinocola, gen. nov. 
Body robust; head broad, more or less recessive over prono- 
tum and pleurites, closely adpressed to prothorax; vertex 
somewhat roundly emarginate over base of antennae; facial 
cones short, truncate, transversely rectangular or nearly so, 
almost contiguous on inner margin, not continuing in plane of 
vertex as in Euphyllura, but distinctly separated therefrom; 
anterior ocellus on front margin of vertex; eyes small; antennae 
short. Thorax broad; propleurites more or less concealed by 
eyes; legs short. Wings more or less coriaceous, not hyaline, 
slightly rhomboidal in outline or elongate-ovate; venation some- 
what similar to Euphyllura. 
Type of genus: Eurhinocola gravelyi, Crawf. 
This genus is closely related to Euphyllura, differing markedly 
in the cephalic characters chiefly. Many of the species heretofore 
included in the genus //inocola will fall into this genus, since 
Rhinocola must be removed to the subfamily Liviinae. Rhinocola 
aceris, I,., the type of that genus, is closely related to Livia in the 
fundamental characters and, therefore, can not include most of 
the species heretofore placed therein. ‘This matter is treated more 
in detail in another paper on Psyllidae which is at present in 
manuscript form.
