Dark browii, covered with a fine gi'eyish pile, varied with fulvous j 

 head narrow, elongate, with a deeply impressed longitudinal line ex- 

 tending from the epistome to the prothorax ; eyes large ; antenna more 

 than three times as long as the body, arising from two approximate 

 nearly erect tubercles ; lip and epistome short ; prothorax about equal 

 in length and breadth, narrowed anteriorly, swelling out considerably 

 at the side, and armed with a small but very distinct tubercle, the disk 

 with a slightly impressed longitudinal line ; scutellum rounded poste- 

 riorly, hairy, the centre glabrous ; elytra rather elongate, subtrigonate, 

 rounded at the apex, granulated at the base, indistinctly punctured, 

 sprinkled with fulvous, behind the middle a small black spot on each ; 

 body beneath dull brown ; legs elongate, especially the anterior pair, 

 which have also their tibise seiTated internally, and armed near the 

 extremity with a short spine, the two basal joints of the tai-si of the 

 same pair dilated at the sides. Length 17 lines. 



The above description is cbawn up from a remarkably fine male, 

 with the antennae alone four and a quarter inches long. The female 

 has a smaller prothorax, nearly parallel elytra, shorter legs, and an- 

 tennae not more than half as long again as the body. It is allied to 

 M. Alcanor, Newm., hipunctatus. 8chon., and fulvo -irroratus, Blount, 

 all of ;which are referable to M. J. Thomson's IViamses, a genus 

 which I have not adopted, inasmuch as the single character which 

 separates it from Monohammm — the spined protibia) of the male — is 

 so graduated that in some species, plorator, AnUnor, etc. for examjde, 

 it is difficult to decide if the little callus, which represents the spine, 

 is sufficient to constitute it a Rhanises. The habit, too, is just as 

 variable as in Monohamim(s.
