Body very dark green, impuiu-tured ; head black, with hardly 

 any appearance of green ; antennae honey-yellow, the joints, ex- 

 cepting the first and second, with darker centres ; palpi and base 

 of the mandibles honey-yellow ; labrum with a slii.'ht projecting 

 angle in the middle of the emargination ; thorax blackish green, 

 hardly narrower at base ; dorsal line indistinct, but more obvious 

 in the middle ; ba.sal indentations dilated not profound ; lateral 

 edge dull honey -yellow ; posterior angles obtuse ; elytra obviously 

 tinged with green ; a little wider at base than the thorax ; striae 

 very slender, inipunctured ; interstitial spaces flat, third space 

 with a puncture at throe-fourths the length from the base ; lateral 

 edge near the tip and suture near the tip obscurely piceous ; tip 

 deeply and rather obtusely sinuous ; beneath black, the greenish 

 tinge hardly perceptible ; feet yellowish ; tsirsi rather darker j 

 first joint of the anteriors of the male souiewhat smaller than the 

 second ; these tarsi have beneath close set hairs. 



Length over seven-twentieths of an inch. 



This species has almost the Amani like form of sonic species 

 of Anisudactj/lus, in which genus I should have placed the spe- 

 cies but for the angle in the emargination of the men turn. It is 

 very closely allied to fcrinhiaftm Say, but is rather more robust, 

 the head and thorax arc differently col<n-ed, the posterior lateral 

 margin is more depressed, &c. [434] It must resemble closely 

 II. agili!^ ^'^i-j of which it may possibly be a variety. 



It was obtained by William Bennett, and presented to me by 

 Mr. Maclure.
