with stiff white hairs; the tibial spine stout and black; the apical tarsal joints reddish 

 at the apex.

Eab. Mexico, Oaxaca {Edge). 



Head as wide as the thorax, coarsely punctured; the eyes small, placed slightly 

 above the middle line, but still distant from the top, the head very slightly dilated 

 behind them ; the lower part of the cheeks bluntly bispinose ; the clypeus toothed 

 stoutly at the sides ; the mandibles black, reddish at the apex. The scape of the 

 antenna? thickly covered with long silvery hair, the flagellum with a whitish pile ; the 

 third joint twice the length of the fourth. The thorax elongate-quadrate ; the base 

 rounded, the apex truncated and with a semioblique slope, the sides very slightly 

 curved inwardly ; coarsely punctured ; the mesopleurse shining, glabrous, except for a 

 slight whitish pile, and impunctate. The abdomen has the basal segment gradually 

 dilated to the apex, and confluent with the second ; its apex, two broad marks on the 

 base of the second segment, the apex of the latter broadly, a broad mark on the sides 

 of the third, fourth, and fifth segments, and the apices of the ventral segments also, 

 silvery-white ; the pygidium covered with dull fulvous hairs. The sides of the second 

 dorsal segment strongly punctured, and more or less rufous, this being also the case 

 with the second ventral segment. The femora sparsely, the tibiae and tarsi thickly, 

 covered with white hairs ; the tibial spines black. 



Similar in coloration to M. rufofemorata, except that the legs are entirely red, but 

 easily distinguishable from that species by the base of the first abdominal segment not 

 being testaceous, smooth, glabrous, and oblique; the thorax is also less concave 

 laterally, and without an incision in the middle ; the median segment is without a 

 tooth on the side ; and the hair on the head and thorax is longer, thicker, and black,, 

 not silvery-white.

Eab. Nicaeagua, Chontales (Belt). 



Head a little wider than the thorax, coarsely punctured, the top bearing fuscous 

 hair ; above the antennae and on the clypeus the hair is pale fulvous, behind the eyes 

 it is shorter and silvery ; mandibles reddish, above black. The eyes rather small, not 

 reaching to the top of the head, which is not much narrowed behind them, and 

 developed laterally a little beyond their width. The scape of the antennae reddish^
