Decatomini. 



Cratodecatoma, gen. nov. 



Antennae apparently 11- jointed, placed in the middle of the 

 head, malar space two-thirds of the length of the eyes ; anten- 

 nal scape not reaching to the ocelli ; antennal depression shal- 

 low, not clearly defined, narrowed above. Ocelli in a curve. 

 Occiput not margined. Pronotxim moderately large, roundly 

 narrowed from the apex to the base, its apex wider than its 

 length. Parapsidal furrows present. Scutellum large, nar- 

 rowed to a point at the base, the apex broadly rounded, mar- 

 gined. Metanotum triangular, with a rounded slope, the sides 

 and centre keeled, and with three or four striae on either side. 

 Abdomen shorter than thorax, the back flat, with the sides 

 rounded ; the first segment is the largest, not quite so long as 

 the following three united, the fourth and fifth longer than 

 the preceding two : the ovipositor short, broad, projecting 

 upwards. Wings with a large cloud in front shortly beyond 

 the middle : marginal vein twice the length of the post-mar- 

 ginal, which is not quite so long as the stigmal branch ; the 

 latter cleft at the apex ; the lower division the larger, it is 

 thicker and triangular. Legs stout, the hinder longer and 

 thicker than the others ; middle tibiae with one spur, the 

 hinder apparently without any. Pronotum and base of meso- 

 notum finely pixnctured, the rest of the latter finely, closely 

 transversely striated. 



The hind tibiae appear to have some bristles behind, but 

 they are not very distinct, and, if really such, are confused 

 with the hair. The antennae are thickened towards the apex ; 

 the pedicle is narrowed towards the base, and is twice longer 

 than it is wide at the apex ; the third joint is longer than 

 wide, the fourth and fifth as wide as long, the others wider 

 than long. I am not sure as to the number of joints, not being 

 certain as to the number in the club ; counting the club as 

 being composed of two and not counting the ring-Joint, there 

 are eleyen,
