^. Length 9 mm. Stature and pubescence as in M. jjuei/i, 

 Guerin, but differs as follows ; legs wholly black, the basal half 

 of the claws rufous ; anterior tarsi not dilated but the basal joint 

 with a long hair-fringe behind. Flagellum wholly black. Pygidial 

 ridge produced into a small triangular tooth, the basal ridge very 

 broadly, semicircularly emarginate, leaving two widely separated

 nervures brown-black. 



St. Vincent (?), No. 106. 



Described from a single ^ specimen. The specimen is 

 without a printed St. Vincent label, and I am uncertain 

 whether it was taken on this island or on Grenada.
