Elongate, narrow, slightly widened posteriorly in ? , 

 shining, Hnely pubescent, and sparsely setose; luteous, the 

 head (tlie labrura excepted) and a rather small apical spot 

 on the elytra black. Head small, the labrum transverse, 

 flattened ; eyes extremely large, contiguous in ^ , very 

 narrowly separated in ? ; antennae long, slender, filiform, 

 joint 11 concave within, twice as long as 10. Prothorax 

 longer than broad, about as wide as the head, sinuate at the 

 sides posteriorly. Elytra elongate, at the middle twice as 

 wide as the prothorax ; densely, finely punctate, the setae on 

 the disc and margins long and conspicuous. 



(^ . Sixtli ventral segment triangularly emarginate ; pos- 

 terior femora moderately incrassate ; posterior tibial hollowed 

 at the apex within, the spurs short ; anterior tarsal joints 1-3 

 with a black comb along their inner edge ; terminal dorsal 

 segment rounded at tip. Genital armature (PI. XIT. fig. 30; :

One male and three females. Near /. maculiventris, which 

 also has the posterior femora incrassate in (^ ; but smaller, 

 narrower, and more shining, the apical spot on the elytra 

 not so large, the ventral segments wholly luteous, the S 

 with peculiarly formed posterior tibiae and dissimilar genital 

 armature. /. bourgeoisi, Pic (1906), from Java, length 12- 

 13 mm., is probably another allied form ; it is described as 

 having slightly dilated posterior femora in (^, the elytra 

 narrow and very elongate, the posterior part only of the 

 head black, &c. 



36. Idgia geniculata, sp. n. 



S . Elongate, narrow, subparallel, shining, finely pubescent, 

 and spai'sely setose; testaceous, the head (the epistoma and 

 labrum excepted), a streak at the apices of the femora, and 

 a rounded spot at the apex of the elytra, black. Head rather 

 small, the labrum transverse, flattened ; eyes large, somewhat 

 narrowly separated ; antennae long, slender, filiform, joint 11 

 concave and longer than 10. Prothorax longer than broad, 

 very little wider than the head, sinuate at the sides posteriorly. 

 Elytra long, at the middle nearly twice as wide as the head ;
