352 Mr. G. C. Champion on the 



antennre long, slender, joint 11 about as long as 10, con- 

 cave. Pi-othorax slightly longer than broad, not wider than 

 the head, sinuate at the sides posteriorly, rugulose. Elytra 

 very long, narrow, subparallel, densely, rugulosely punctate. 

 Anterior tarsal joints 1-3 with a narrow comb along their 

 inner edge. Terminal dorsal segment rounded at apex. 

 Genital armature (PI. XII. fig. 28): lateral lobes long, narrow, 

 almost straight, angularly dilated on their lower edge basally, 

 as seen in profile ; median lobe stout, feeblj curved, gradually 

 acuminate to the tip. 



? . Antennae darker at base ; eyes less approximate ; pro- 

 thorax with two large, oblong, black patches on the disc, 

 densely rugulose ; scutellum iufuscate ; elytra uniformly 

 nigro-fuscous (the pallid sutural and outer margins excepted) 

 to the tip. 



Length (excl. head) 8|-9|, breadth 2|-3 mm. 



Hab. S. India, Anamalai Hills (H. L. Andrewes) . 



One male [type] and two females, assumed to be the 

 sexes of the same species. A close ally of /. nilgirica with 

 the sutural and outer margins of the elytra testaceous to 

 near the tip, the genital armature very different. The c? has 

 the apices of the elytra peculiarly marked, the black apical 

 spot being bordered in front by a pallid undulate line. 

 /. circumdata, Pic (1909), from " Indes ou Java," and 

 /. suturalis, Kirsch (1875), from Malacca, must be allied 

 forms, the latter having the prothorax wholly testaceous. 



33. Idgia viridivittafa, sp, n. 



? . Very elongate, narrow, depressed, subopaque (the 

 head excepted) above, shining beneath, finely cinereo-pubes- 

 cent, the head with several long bristly hairs ; the epistoma, 

 palpi, antennae, margins, apex, and base of prothorax, 

 sutural region (broadly) and outer margin (narrowly) of 

 elytra, and bases of femora, testaceous, the labrum black, 

 the head between and behind the eyes, a broad space across 

 the disc of the prothorax, and the legs in great part, nigro- 

 cseruleous, the scutellum, a broad vitta extending down the 

 outer part of the disc of the elytra to near the apex, and 

 the under surface (the testaceous ventral sutures excepted) 

 green or bluish green. Head small, produced in front, the 

 epistoma transverse, convex, extending forwards, limited 

 behind by a deep groove ; labrum transverse, subtrapezoidal ; 

 antennse long, slender, filiform ; eyes large, rather widely 

 separated. Prothorax as long as broad, wider than the head, 

 narrowed anteriorly, transversely depressed towards the base,
