Malacoderm Genera Prionocerus and Idgia. 351 
setose ; testaceous, the head (the labrum and anterior margin 
of epistoma excepted) black ; the elytra nigro-fuscous or 
fusco-violaceous, with the sutural and outer margins very 
narrowly testaceous at the base or to near the apex, the 
apices sometimes with an indeterminate black patch ; the 
antenne in one specimen fusco-annulate. Head slightly 
produced anteriorly, the labrum transverse; eyes very 
large and subcontiguous in ¢, narrowly separated in 9 ; 
antenne slender, joint 11 a little longer than 10, Pro- 
thorax about as wide as the head in g, longer than broad, 
wider in ?, stongly sinuate at the sides posteriorly, closely, 
rugulosely punctate. Elytra very long, quite narrow in g; 
densely, rugulosely punctate, with rows of somewhat con- 
spicuous granules on the disc. Terminal dorsal segment of 
tiie abdomen simple. 
Var. The elytra testaceous with an indeterminate black 
patch at the shoulders and apex. (2. 
&. Anterior tarsal joints 1-8 with a black comb along 
their inner edge. Genital armature (Pl. XII. fig. 27): lateral 
lobes short, broad, slightly curved, as seen from above; 
median lobe curved, compressed from about the middle, and 
drawn out into a blunt, downwardly directed point. 
Length (excl. head) 8-11, breadth 2-3} mm. (¢ $.) 
Hab. Inpra, Nilgiri Hills (H. L. Andrewes). 
Two males and ten females, including two of the varicty 
which corresponds with the var. diversipennis of 1. gorhami, 
Pic. More shining than J. flavolimbata from the Anamalai 
Hills, the antenne, legs, and under surface testaceous, the ¢ - 
armature very different. The males are much narrower than 
specimens of the same sex of J. gorhami, and are separable 
therefrom by the simple terminal dorsal segment of the 
abdomen, the pale sutural and outer margins of the elytra, 
ani the ¢ -armature. 
32. Idgia flavolimbata, sp. n. 
$. Elongate, narrow, subparallel, depressed, shining, the 
elytra dull; finely pubescent and sparsely setose; fuscous, 
the head (the labrum included) black, the palpi, base and tip 
of the antennee, prothorax (a broad space on the disc excepted), 
scutellum, mesosternum, coxe, and bases of femora, tes- 
taceous ; the elytra with a sharply defined black patch at 
the apex, the sutural and outer margins to near the tip, the 
extreme base, and an indeterminate undulate fascia preceding 
the apical spot, testaceous. Head moderately long, the 
‘labrum transverse, concave ; eyes very large, subcontiguous ;
