370 Mr. G. C. Champion on the 
60. Ldgia pallidicolor. 
Tdgia pallidicolor, Pic, L’Echange, xxii. p. 43 (1906); Bull. Soc. Ent. 
Fr. 1910, p. 346. 
3g. Anterior tarsal joints 1-3 with a narrow black comb 
along their inner edge ; terminal dorsal segment emarginate 
in the middle at tip; sixth ventral segment (Pl. XII. 
fig. 49 a) deeply, narrowly, obliquely bi-excised at apex, the 
median portion shorter than the broader, truncate, curved 
lateral portions. Genital armature (Pl. XII. fig. 49) : 
lateral lobes long, narrow, more or less emarginate on their 
lower edge before the tip; median lobe long, almost straight, 
curved downward into a blunt point at apex. 
Hab. Java [type], Depok (G. . Bryant, 18.iv. 1909: 3); 
Sram, Renong (Doherty: § 2); Mauacca, Perak (Doherty : 
& 2), Penang (G. H. Bryant, x.19138: ¢ 2); Borneo, 
Quop (G. E. Bryant, 27.11.1914: 2); Tenasserim, Tavoy 
(Doherty: $ 2); Burma, Karen Mts. (Doherty: 3); 
Assam, Patkai Mts. (Doherty: ¢ ). 
A small, narrow, shining, pale testaceous form, with the 
tips of the elytra black ; the head usually infuscate around 
the eyes, sometimes wholly testaceous, or with the base 
black (those from Penang and Borneo); the basal joints 
of the antenne, the tibiz and tarsi, and in some specimens 
the apices of the femora also, infuscate, rarely entirely 
testaceous ; the antenne long and slender, with the almost 
simple apical joint about as long as the tenth; the eyes very 
large, approximate in ¢, narrowly separated in 9. Amongst 
the numerous closely allied insects from the same region, 
I. pallidicolor, as here identified, is recognizable by the 
trilobed sixth ventral segment of the male, and the non- 
elongated eleventh antennal joint in the two sexes, a 
character used by Pic in his first table of the Javan and 
Sumatran forms. Males from the localities quoted have been 
dissected: those from Java, Tenasserim, and Burma agree 
inter se; but the one from Penang (with blacker head) has 
the median lobe of the last ventral segment notched in the 
middle, that from Perak having the corresponding lobe 
longer, narrower, and rounded at the tip. 
61. Idgia dasytoides, sp. n. 
?. Elongate, very narrow, slender, moderately shining, 
closely cinereo-pubescent, and sparsely nigro-setose ; green 
or brassy-green, the antenne piceous, the basal joints and
