 bark of a fallen tree, within half a mile of the mouth of the crater.

This species is pretty closely allied to Sliarpi and rtipicola. Sharpi 

 is easily distinguished from the other two by its being winged, as well 

 as by its extremely parallel form, deep black colour, &c. Incendinrms 

 differs from rupicola by its much narrower and more elongate build, 

 and by the form of its thorax which is scarcely narrower in front than 

 at base, and only moderately emarginate in front, with rounded an- 

 terior angles, — whereas, in rupicola the thorax is much contracted in 

 front, where it is deeply emarginate, with strongly produced and 

 sharp anterior angles. I observe in all my specimens of Sharpi and 

 incendiarius a rather conspicuous impression (which is quite wanting 

 in rupicola) on the outer side of the abbreviated sutural stria, and 

 close to the base of the elytra. All three have a few impressions on 

 the 3rd interstice, in common with nearly all Hawaiian CaralidcB. 



In the original description of A. rupicola (E. M. M., vol. xv, p. 

 122, line 12), the word " leviter" should be omitted, as it conveys the 

 opposite meaning to what I intended. 



The two species of Anchomenus described above are both members
