1912. | D. L. Crawrorp: Indian Psyllidae. 423 
Head almost as broad as thorax, closely adpressed to 
prothorax, scarcely deflexed; vertex a little broader than long, 
rather plane, with a shallow fovea discally on each side of median 
line, almost straight behind, anterior margin roundly emarginate 
above antennae; facial cones short, broad, transversely rectangular, 
somewhat deflexed from plane of vertex and distinctly separated 
therefrom by a deep suture (not as in Euphyllura), scarcely 
pubescent; anterior ocellus visible from above; eyes small, white, 
slightly recessive over pronotum; labrum visible from front. 
Antennae short, not longer than width of head, rather thick. 
Thorax broad, robust, short; prothorax moderately long, 
rather flat transversely, concealed somewhat laterally by recessive 
eyes; propleurites mostly concealed by eyes; coxae small; legs 
short, relatively stout. Wings small, somewhat coriaceous and 
wrinkled, not transparent, a little more than twice as long as 
broad, very slightly rhomboidal in outline; first marginal cell 
elongate; cubital petiole twice as long as discoidal subcosta; 
pterostigmal vein almost obsolete. Hind wings smaller, hyaline. 
Male—Abdomen constricted at base of genitalia; latter 
large; anal valve large, bilobed; claspers large, acute at tip, 
simple. Female—Genital segment as long as rest of abdomen, 
deflexed, acuminate; ventral valve shorter than dorsal, more 
acute. 
Described from a considerable number of specimens of both 
sexes collected by F. H. Gravely from the ‘‘ jungle between foot 
of Dawna Hills and Burmo-Siamese Frontier.’’ I take pleasure 
in naming this species after the collector.

(Pikeoacti tassel, Jeo dye Vi Dib scan Shion G.) 
Length of body 2:2 mm.; length of forewing 2°2 mm.; greatest 
width ‘9 mm. ; width of vertex between eyes 39 mm.; with eyes 
63 mm.; length from crown to tip of cones ‘4m mm. General 
colour whitish and dark brown or black; dorsum and vertex

flat, with a fovea on each side of median line posteriorly; anterior 
margin marked by an impressed line between vertex and facial 
cones ; latter large, broad, rounded at tip, contiguous, about two- 
thirds as long as vertex, emarginate laterad in front of antennae,
