Elongate, narrow [S), broader (?), subparallel, feebly 

 shining, finely pubescent, and sparsely nigro-setose ; testa- 

 ceous, the head (the labrum excepted), and a large oblong 

 patch on each side of the prothorax, black, the antennse (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 ; 

 antennse 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. 



^ . 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. (c? ? •)

 son, A. K. Weld Downing). 



Two males and eight females. Narrower than I. gorhami, 

 the prothorax rougher and nigro-bimaculate, the legs and 

 antennse partly infuscate. The ($ has a similarly cleft (or 

 bilobed) terminal dorsal segment, but the genital armature 

 is very different. The allied /. flavolimbata and /. marginata, 

 from the same region, have the sutural and outer margins of 

 the elytra more or less testaceous, and the terminal dorsal 

 segment simple. /. maculicollis, Pic (1906), from Java, has 

 a similarly maculate prothorax. 



27. Idgia caruleiventris, sp. n. 



Elongate, narrow, subparallel, shining, closely cinereo- 

 pubescent, and sparsely nigro-setose; nigro-fuscous, the 

 head black, under surface and femora bluish or violaceous, 

 the palpi, basal joints of the antennae, prothoi'ax, and tarsal 

 claws testaceous. Head slightly elongated anteriorly, the 

 labrum transverse; eyes large, narrowly separated in (^, 

 more di>tant in ? ; antennse 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 



* Not visible in profile figure.
