form less robust than M. femoratus Fab., and with the posterior 

 femora much more slender and scarcely curved. Apical joint of 

 antenna? bright orange, much longer than the others, the basal joint 

 about equal to the second. Rostrum reaching the tip of the interme- 

 diate coxae, hairy, more or less tinged with yellow. Pronotum a 

 little broader than long, the humeri prominent, bluntly subacuminate, 

 having a slightly backward curvature; the surface finely remotely 

 punctured, and with small, scattered tubercles, some of which are 

 excavated, the lateral margins deeply sinuated, the subcarinate edge 

 bearing a few short, oblique, rather remote teeth, margins behind the 

 humeri granulated. Scutellum transversely wrinkled, the extreme 

 tip orange. Hemelytra minutely, closely punctured, the punctures 

 becoming a little coarser upon the clavus, the costal area near its base 

 bearing a few minute granules. Antepleura shining, granulated, 

 punctured; the odoriferous glands fulvous. Legs blackish piceous; 

 the tarsi and ends of the tibia? fulvous, nails piceous; posterior femora 

 almost straight, the teeth graduating in size towards the tip, the five 

 in a row nearest the tip large and curved; posterior tibiae dilated 

 exteriorly through two-thirds of their length, sinuated on the middle, 

 the base of the sinus almost acutely angulated, the opposite end 

 tapering and beyond this a few small, remote teeth; the inner dilata- 

 tion feeble, extending to about the middle, beyond this to the tip 

 minutely tuberculate-denticulate, the upper and lower surface of the 

 dilatation granulated.

Dark brown, blackish fuscous beneath, clothed with yellowish, 

 almost prostrate hairs, which extend also upon the legs. 



Form and general appearance of the preceding species, but easily 

 recognized by the long and very robust posterior femora. Antenna? 

 slender, fuscous, the apical joint fulvous, longer than the basal joint. 

 Pronotum minutely tuberculated, a few of the tubercles excavated, 

 the humeral angles a little curved upwards, bluntly subacuminate; 

 lateral margins subcarinate, armed with small, rather remote, tuber- 

 cular teeth, the sides subsinuated. Antepleura polished, granulated, 

 anteriorly with a few coarse punctures. Odoriferous glands orange. 

 Scutellum a little elevated on the disk, each side with a shallow 

 impression, surface transversely, obsoletely wrinkled, the extreme
