entad on apices of tibize; meracanthi short, about one and one- 
third times as long as thickness at base; ungues broadly curved. 
Fore and middle legs shorter than hind. 
Abdomen about one and two-sevenths times as long as thorax, 
about one and four-fifths times as long as thick; thickness sub- 
equal to width. Genitalia about half as long as total length of 
abdomen; genital segment produced caudoventrad beyond genital 
forceps at an angle of 30° to 40° from median line of body; 
distance from apex of elongation to base of segment about three 
times width. Anal valve about one-sixth total length of ab- 
domen, about one and one-third times as long as wide, somewhat 
attenuate and rounded apicad, abruptly petiolate basad. Genital 
forceps subequal in length to anal valve, about three times as 
long as wide, slightly thicker proximad than distad, nearly trun- 
cate at apex. Anal valve and genital forceps more ee hairy 
than the rest of body. 
Female.—Abdomen subequal in length to thorax. Genitalia 
about half total length of abdomen. Dorsal valve about one 
and one-seventh times as long as ventral, about two and a half 
times as long as thickness at base, about half as thick at distal 
half as at basal, rounded at apex. Ventral valve about six times 
as long as thickness at base, acute apicad. Dorsal and ventral 
valves more thickly hairy than the rest of body. |

LuzoN, Manila, Government Laboratories accession No. 5160, 
February 17, 1906, one male, one female, and one imperfect 
specimen with broken genitalia (Banks); Manila, Bureau of 
Science accession No. 14771, November 16, 1911, two specimens 
(Banks), on Calophyllum inophyllum L. (Guttiferee) ; Laguna, 
Los Bafios, College of Agriculture accession No. 18348, March 11, 
1918, eleven males and nine females (Uichanco), on the same 
Plant. The gall has been previously described (Uichanco 
"19: 544, pl. 13, fig. 4). 
The present variety differs from the species, as originally 
described by Crawford, as follows: Longer vertex in proportion 
to width, presence of waxy bands on vertex and notum; 
slightly longer antenne; absence of basal spur on hind tibie; 
longitudinal bifurcation of hind wings; red spots on the abdomen 
(not evident in one female of the series) ; and additional brown 
spots on forewings. The type of the species is unfortunate- 
ly a single, partly mutilated example, and the differences noted
