quiuto sextoque rufis ; alis fusco-hyaliuis, venis nigris ; segmeuto 

 mediano ruguloso. 



Long. 13 mm. 



9 . Head rectangular, about half as broad again as long, smooth 

 and shining, with a few scattered punctures, a deep sulcus reaching 

 from between the antennae to half way to the anterior ocellus ; 

 posterior ocelli situated on the sides of large depression, further from 

 the eyes than from each other ; eyes rather large, separated from the 

 posterior margin of the head by a distance equal to about half their 

 own length ; scape smooth above, clothed with long yellowish hairs 

 beneath. Prouotum shining, with sparse, large, more or less elongate 

 punctures, about twice as long as the scutellum. Pleurae coarsely but 

 rather sparsely punctured, the sides of the median segment finely 

 obliquely striated. Dorsal area of the median segment closely rugu- 

 lose, verging into fine oblique striae near the sides, the posterior slope 

 transversely rugulose. Abdomen shining, sparsely and finely punc- 

 tured, with sparse whitish pubescence on the sides. Second cubital 

 cell present, triangular, the side on the cubitus shorter than the others. 

 Stigma large, situated near the middle of the costa.

This is nearest to M. rufifrons Fabr., but is a less robust species, and 

 differs in the sculpture of the median segment, which is smooth in the 

 middle with a longitudinal sulcus in rufifrons, rugulose without a 

 sulcus in cruenta ; also in the narrower shape of the triangular second 

 cubital cell, and in the colour of the head and apical segments of the 

 abdomen. The second recurrent uervure is almost straight in cruenta, 

 but strongly bent inwards towards the cubitus in rufifrons.

9 . Head subrectangular, a little broader than long, smooth and 

 shining, without a frontal sulcus ; eyes large, elongate-ovate, separated 

 from the posterior margin of the head by a distance scarcely equal to 

 their own breadth. Thorax shining, with a few scattered punctures on 

 the mesonotum and scutellum ; prouotum twice as broad as long, with 

 a row of small setigerous punctures on the anterior margin. Pleurae
