Bornéo (Sarawak : J C. Moulton). 



Smaller than M. gracilis Westw., the only species bitherto 

 described, and distinguished by the longer rostrum, the lack of the 

 tooth at the apical angles of the second abdominal segment, the 

 much less tuberculated hind femora having a single séries of 

 tubercles (four in gracilis çf), the colour of the female tibiœ, and, 

 above ail, by the total absence of the « two long diverging spines » 

 at the junction of the second and third ventral segments in the 

 maie. This last character is very remarkable in considération of the 

 close relationship between the two species. If Distant's figure 4a is 

 correct, the hind coxœ also seem to be somewhat more wide apart 

 in gracilis than in Moultoni. 



The maie and female of M. Mouttoni are from the same locality 

 and doubtless belong to the same species. Westwood's type, a 

 female, was from Java, and the maie from Singapore, described by 

 Distant as being that of gracilis is longer than the female whereas
