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 much less 

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

 in leno-th and the anterior border of the former, like both margins of the propodite are fringed 

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

 joint and strongly curved backward. 



The abdomen of the d 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 

 first two seo-ments are short and provided with a transverse rim; 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 

 triano-ular 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 Catiiatopsis , a narrow plate is intercalated between the 4'^ and the 5'^ segment, 

 covering the external genital ducts. 



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

 One of the 9 from the Bay of Batavia is bearing 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.
