348 Mr. G. C. Champion on the 
Elongate, narrow (¢), broader (2), subparallel, feebly 
shining, finely pubescent, and sparsely uigro-setose; testa- 
ceous, the head (the labrum excepted), and a large oblong 
patch on each side of the prothorax, black, the antennze (ex- 
cept at the base and tip), elytra and legs (except the bases of 
the femora to a variable extent) fuscous or nigro-fuscous, 
the elytra sometimes with a faint bluish tinge. Head rather 
long, narrow, the labrum transverse, trapezoidal, concave ; 
antennz slender, filiform, joint 11 concave, a little longer 
than 10. Prothorax slightly longer than broad, sinuate at 
the sides posteriorly, densely, rugosely punctated. Elytra 
elongate, densely, rugulosely punctured, and with rows of 
scattered granules on the disc. 
6. Anterior tarsal joints 1-3 with a narrow comb along 
their inner edge; terminal dorsal segment deeply, narrowly 
cleft in the middle at apex (the notch much deeper than in 
?). Genital armature (PI. XI. fig. 23): lateral lobes curved, 
broad ; median lobe drawn out into a long, slender, com- 
pressed piece, which (as seen from above) is feebly dilated 
and somewhat spoon-shaped at the tip *. 
Length (excl. head) 8-11, breadth 2-3 mm. (¢ ?.) 
Hab, Invia, Nilgiri Hills (A. L. Andrewes, Sir G, F. Hamp- 
son, A. K. Weld Downing). 
Two males and eight females. Narrower than J. gorhami, 
the prothorax rougher and nigro-bimaculate, the legs and 
antennze partly infuscate. The gd has a similarly cleft (or 
bilobed) terminal dorsal segment, but the genital armature 
is very different. The allied I. flavolimbata and I. marginata, 
from the same region, have the sutural and outer margins of 
the elytra more or less testaceous, and the terminal dorsal 
segment simple. J. maculicollis, Pic (1906), from Java, has 
a similarly maculate prothorax. 
27. Idgia ceruleiventris, sp. u. 
Elongate, narrow, subparallel, shining, closely cinereo- 
pubescent, and sparsely nigro-setose; nigro-fuscous, the 
head black, under surface aud femora bluish or violaceous, 
the palpi, basal joints of the antenn, prothorax, and tarsal 
claws testaceous, Head slightly elongated anteriorly, the 
labrum transverse ; eyes large, narrowly separated in g, 
more distant in ?; antennz long, slender, a little shorter 
in ?, joint 11 concave within, considerably longer than 10. 
Prothorax about as long as broad, very little wider than the
