Malacoderm Genera Prionocerus and Idgia. 365 
blunt at the tip ; median lobe feebly sinuate, drawn out into 
a curved point at the apex. 
Length (excl. head) 8-9, breadth 2 mm. (¢ ?.) 
Hab. Java (Bowring, Horsfield). 
Four specimens, two of each sex, are referred to J. fruh- 
storferi, Pic, but they differ from his second amended 
definition in having the head infuscate behind the eyes, 
which is certainly a variable character. A ¢ from Tenas- 
serim may also belong to the same species? The small 
apical spot, the wholly testaceous labrum, antenne, and 
legs, the long apical joint to the antennz, and the form of 
the lateral lobes of the g-tegmen are its chief characters. 
The slender posterior femora of the male separates the 
present insect from /. bourgeoisi, Pic (1906), from the same 
island, as well as from J, flavilabris, from Perak and Penang. 
52. Ldgia apicata. 
Ldgia apicata, Gorh. Ann. Soc. Ent. Belg. xxxix. p. 520 (1895). 
6. Anterior tarsal joints 1-3 with a black comb along 
their inner edge ; sixth ventral segment triangularly emar- 
ginate at tip. Genital armature (PI. XII. fig. 42): lateral 
lobes long, broad, sinuous on their inner edge above, slightly 
hollowed near the tip beneath, the apices incurved and 
obtuse as seen from above ; median lobe sinuate, drawn out 
into a curved point at apex. 
Hab. Mauacca, Singapore (4. R. Wallace: 3 ¢). 
Two specimens, ¢ 9, in the Oxford Museum, from the 
same source as the type, are presumably referable to 
I. apicata. A narrow, testaceous form, with the head 
(‘he anterior portion excepted) and the tips of the elytra 
black ; the antennze long and slender, with joint 11 twice 
as long as 10, and hollowed within; the eyes very large, 
contiguous in 6, very narrowly separated in ?; the elytra 
somewhat produced at the tip, and with the blackish sete 
long and very conspicuous. 
53. Ldgia dohertyi. 
Idgia setifrons (Kirsch), var. doherty?, Pic, Bull. Soc. Ent. Fr, 1912, 
p- 300. 
3d. Elongate, narrow, shining, finely pubescent, and 
sparsely fusco-setose ; pale testaceous, the head around the 
eyes (in one-specimen in great part, the anterior portion 
excepted), the eyes themselves, and the tips of the elytra,
