propodites, compressed and hairy along the edges and on the ventral surface, entirely straight. 

 The last pair of legs differs in several points: the armature of the meropodite is inuch less 

 pronounced or even absent, carpo- and propodite, especially tlie latter, are flattened and subequal 

 in length, and the anterior border of the fermer, Hke both margins of the propodite are fringed 

 with long hairs, continued on both edges of the dactylus, which is fuUy as long as the preceding 

 joint and strongly curved backward. 



The abdomen of the cf is rather short, by far not reaching to the buccal cavity; at its 

 base it covers only one-third of the interspace between the bases of the last pair of legs ; the 

 hrst two segments are short and provided with a transverse rini ; the third segment is broader 

 than the first, much projecting sideways, and indistinguishably fused with the two next segments, 

 as Alcock already observed; the penultimate joint is broader than long and as long as the 

 triangular seventh segment. The first abdominal appendages are robust, covered by the abdomen. 

 Sternum granulate, especially at the end of the deep trench of the abdomen-, Alcock stated 

 that, like in Cainatopsis, a narrow plate is intercalated between the 4''^ and the 5* segment, 

 coverino- the external genital ducts. 



The abdomen of the 9 's seven-jointed, the penultimate segment being by far the strongest. 

 One of the 9 from the Bay of Batavia is hearing eggs, the diameter of which measures 0.77 mm. 



Alcock obtained his specimens from Madras. The species seems to be abundant in the 

 Gulf of Siam.

Lenz refers his genus to the Hexapodinae, but the last pair of legs is normally developed. 

 Provisionally I include it into the present subfamily. 

 The genus contains but a single species.
