Metaxyphus very short, baso subtriangularly produced. Anterior fé- 

 mora not (comparatively) incrassate. Intermediate femur twice as long 

 as tibia, which is one-half longer than tarsus, claws nearly one-half 

 longer than tarsus. Elytral markings not divided into series by longi 

 tudinal dark lines. [Abdomen above, and entire ventral surface pallid 

 luteous; these specimens are, however, scarcely quite mature].

d" Frontal fovea ovoid , profound and wide, extending backwards 

 between the eyes to abont two-thirds of their length (as seen from 

 below. [fig. 10]. Pala subarcuate, dorsum rising at base subperpendicu- 

 larly to almost the same height (from the dorso-apical portion of the 

 tibia) as the height of the tibia at its apical margin, then sloping gradually 

 towards the apex. The row of teeth is very remarkable ; starting near 

 the base (at the middle heigth) and contiwuing subparallel-like to the 

 ventral margin to a little beyond the middle of the pala, 15 very small, 

 subconical (inverted) teeth being comprised. Then there is a slight rise 

 and a swift decline, 11 very long, attenuated, apically acuminate teeth 

 (the middle 6 very long, comparatively) [fig. 11 & 12]. The strigi! is 

 exceedingly small, more minute than that of any other Corixa with 

 wich I am acquainted its length being only about one-fiftcenth of the 

 bieadth of the abdomen at that part. 



Unfortunately ali the males are rather immature. The strigil in each 

 is more or less folded over, so that I ha ve not been able te figure it. It 

 appears to be subovai (or suboblong) with 4 broad regular rows of teeth 

 & one short sinistro-lateral apical row.
