moderately distinct longitudinal grooves, truncate behind, scutellum 

 raised, rounded, a little aculeate behind ; tegulae nearly black, wings 

 sub-chalybeate, met,athorax elongate, attenuate from the median part 

 towards the apex, foveolate and with a distinct median longitudinal 

 ridge reaching from base to apex ; first abdominal segment of 

 abdomen moderately long, not very slender and angular on each 

 side at base, hardly narrower at apex than the base of the second, 

 which is rounded laterally, and one-quarter longer than broad, both 

 these segments are closely punctured without any raised intervals ; 

 tibicB without any spine, spurs except the anterior ones ivory-white ; 

 ventral carina of the first segment sharp and produced at apex in a 

 distinct tooth, second abdominal segment without a carina. Length 

 16 mm. 



This species might prove to be identical with M. atropos, Sm. 



The resemblance with the three preceding species is quite super- 

 ficial, and is due to the colour ; the shape of the eyes, of the 

 mesothorax, and of the ventral carina of the first segment is quite 

 different.

$ . Head, antennae, tibiae, and tarsi ferruginous-red ; thorax red ; 

 second abdominal segment with a supra-lateral slightly flavescent 

 silky patch situated at about the median dorsal part, third and fourth 

 segment with a band of similar pubescence ; antennae long, slender ; 

 head rounded laterally behind, very rugose, and clothed with a short 

 sub-flavescent pubescence and a few long black hairs, eyes large, 

 lateral, reaching beyond the median part of the outer sides ; ocelli 

 placed very far back and not very distinct ; thorax elongate, not 

 truncate at apex, but very little sloping and with the anterior angles 

 rounded, nearly parallel from the anterior angle to about the median 

 part, where it is deeply coarctate laterally as well as on the disk, 

 posterior part, or metathorax, a little raised, convex and vertical 

 behind, it is closely foveolate, the outer sides are not crenulate, 

 there is a faint trace of the suture dividing the prothorax from the 

 mesothorax, the scutellum has disappeared, and the upper angle of 

 the lateral constriction is a little angular ; above it there is a very 

 small wart, \vhich seems to be a rudimentary form of the tegula, 

 and there are no wings ; abdomen sub-sessile, basal segment dentate 

 on each side, covered with elongated punctures, and at apex half the 

 width of the base of the second joint, which is one-fourth longer than
