SyAGKTJS MASHOIfANUS, n. Sp. 



Black or fulvous, the apical joints of the antennae and the knees 

 black ; thorax impunctate, elytra strongly punctate-striate, femora 

 dentate. 



Mas (■?). Thorax fulvous ; elytra flavous ; legs flavous, -with or 

 without dark knees. 



Fern. (?). Thorax black ; elytra flavous, the sutural and lateral 

 margins and a round spot before the middle greenish black. 



Length 2 lines. 



Head finely punctured at the vertex, the clypeus more strongly 

 and closely punctured, scarcely separated from the face ; antennae 

 long and slender, fulvous, the apical joints more or less fuscous or 

 black, the second joint but slightly longer than the third, this and 

 the following joints elongate and slender ; thorax subcylindrical, 

 about one-half broader than long, the anterior portion rather 

 strongly defiexed at the sides, the latter moderately rounded, the 

 surface impunctate, fulvous in the male, black in the female ; elytra 

 subcylindrical, strongly punctate-striate, the punctures finer 

 towards the apex, entirely flavous, or each elytron with a round or 

 elongate black spot befoi'e the middle, the sutural and lateral 

 margins likewise black in the female : underside black; legs fulvous, 

 the femora with a distinct tooth, the knees and the first two joints

 coarsely punctured ; the anterior margin of the thoracic episternum 

 slightly convex.

The diiSerent coloration in the sexes of this species is rather 

 peculiar and constant in the six specimens before me ; the sexes have 

 been pointed out by Mr. Marshall, who has probably taken them 

 in copvld. The male is of nearly entirely fulvous coloration above, 

 although in one specimen the suture is obscurely marked with a 

 fuscous band, but the elytral spots are absent ; the legs are likewise 

 either entirely fulvous or have the knees darker, but this is never 

 so pronounced as in the female ; in the latter the thorax is black 

 and shining and the head is sometimes likewise marked with black 

 on the vertex.

Below piceous, the basal joints of the antennae and the legs 

 fulvous ; thorax greenish aeneous, rugosely punctate ; elytra obscure 

 fulvous with metallic gloss, the sutural and lateral margins 

 narrowly blackish, surface strongly punctate-striate ; posterior 

 femora with a minute tooth. 



Length 1| line. 



Head flat, strigosely punctured on the vertex, the rest of the 

 surface remotely and finely punctate, eyes widely separated, 

 surrounded by a narrow sulcus ; clypeus not separated from the 

 face, more strongly punctured ; antennae extending to the middle of 

 the elytra, the lower seven joints fulvous, the others fuscous, third 

 and fourth joints slender, equal, the basal and the second joint
