Malacoderm Genera Prionocerus and Idgia. 363 
48. Idgia rostrifera, sp. n. 
?. Elongate, rather dull, thickly pubescent, and sparsely 
setose ; obscure rufo-testaceous, the head (the epistoma and 
labrum in great part excepted), scutellum, a patch at the 
apex of the elytra, the sixth ventral segment, and apices of 
the femora black, the tarsi slightly infuscate. Head long, 
narrow, the mandibles, epistoma, and labrum elongated, the 
labrum distinctly longer than broad, foveate in front ; eyes 
large, separated by a rather wide space; antennz long, 
slender, filiform, joint 11 constricted at the middle, a little 
longer than 10. Prothorax longer than broad, much wider 
than the head, very uneven, and closely, rugulosely punctate. 
Elytra long, subparallel, densely, rugulosely punctate, and 
with the usual rows of granules on the disc. 
Length (excl. head) 9, breadth 3 mm. 
Hah. Inpvra, Anamalai Hills (A. L. Andrewes). 
One specimen. Separable from J. melanura and I, assi- 
milis, and all the similarly coloured Indian forms known to 
me, by the anteriorly elongated, subrostrate head, the 
labrum being longer than broad and foveate in the centre 
in front. The larger size, black knees and sixth ventral 
segment, elongate labrum, &c., distinguish J. rostrifera from 
T. luteipes, which was found by Mr. Andrewes in the same 
locality. The Arabian J. arabica and J. laticorms have a 
similarly elongate head. 
49. Idgia maindront. 
Idgia maindroni, Pic, Bull. Soc. Ent. Fr. 1909, p. 245. 
gd. Auterior tarsal joints 1-3 with a comb along their 
inner edge; terminal dorsal segment broadly subtruncate 
at tip. Genital armature (Pl. XII. fig. 40) : lateral lobes 
broad, moderately long; median lobe broad, as seen from 
above, abruptly acuminate and hooked at the tip. 
Hab. S. Invta, Wallardi in Travancore [type], Nilgiri 
Hills (WH. L. Andrewes: $ 2). 
A pair from the Nilgiri Hills are referred to this species. 
They are very like the larger examples of J. dimelena,Walk. 
(=cardoni, Bourg.), but have the head more produced in 
front and testaceous from the eyes forward, the latter very 
largein ¢; the elytra relatively longer, more shining, dis- 
tinctly tricostate on the disc, and with a small black spot at 
the tip; and the pubescence longer, with very few sete 
intermixed.
