to the posterior declivity which is vertical ; it is closely and irregu- 

 larly foveolate, and the line dividing the metathorax from the meso- 

 thorax is visible, the outer sides are not serrulate, and there is only 

 a very small, hardly noticeable lateral tubercle at- the junction of the 

 meso- and metathorax ; abdomen nearly sessile, basal joint very 

 short, dentate on each side at the base, not so broad at apex as the 

 base of the second segment which is nearly one-third longer than 

 broad, and covered for two-thirds of the length with longitudinal, 

 slightly wavy raised lines ; ventral carina of first segment short, 

 laminate, truncate at both ends, and slightly emarginate near the 

 centre ; tibiae with a very distinct double series of spines, spurs 

 reddish ; pygidium finely aciculate longitudinally. Length 8-11 mm.

Belongs to the same group as M. agave ? , Per. ; it is easily 

 recognised by the quadrate form of the cheeks, which are very

? . Black, with the antennas sub-rufescent for half the length, ver- 

 tical part of the head with a sub-rufescent posterior patch ; thorax 

 red, abdomen with the first and second segments fringed with a 

 narrow silky white pubescent band, second segment with an ovate 

 white patch in the centre of the base, third segment banded with 

 white ; head a little broader than the apex of the thorax, nearly 

 twice as broad as long on the vertex, eyes large, lateral, reaching to a 

 little beyond the outer sides which are a little diagonal, deeply and 

 closely pitted, and clothed with a very short flavescent pubescence 

 and a few long black hairs ; thorax elongate, straight at apex but 

 with the outer angle a little rounded, nearly parallel for half the 

 length, slightly and gradually, but not very conspicuously, narrowed 

 from there to the posterior declivity where it is about one-third 

 narrower than at apex; it is closely pitted and clothed with a 

 very short, not dense, flavescent pubescence and a few black 

 hairs, the outer margin is not serrulate except along the posterior 

 declivity, the upper part of which, however, is also slightly 

 serrulate and has a distinct median tubercle ; first abdominal seg- 

 ment nodose, sharply dentate on each side at base, one-third 

 narrower at apex than the base of the second one which is ovate, 

 and both covered with very closely set, slightly elongate punc- 

 tures hidden by a dense black pubescence ; ventral carina of first 

 abdominal segment long and very deeply emarginate in the centre;
