Qualified by this latter remark, the particular members of the genus 

 which I have had an opportunity of examining may be arranged as 

 follows : — 



§ I. AntennoB 9- et lO-articulatce. 



1. Kunzcsi, Aube ; America, India, Japan, Madeira, &c. 



2. singularis, Beck (= difficilis, Villa, de-pressus, Curt., Villee, 



Aube) ; Europe, Canaries, &c. 



3. ellipticus, Woll. ; Japan. 



4. signatus, Woll. ; Japan. 



5. capitatus, Woll. ; Japan. 



§ II. AntenncB ll-articulatcB. 



6. caularum, Aube (= PancTcoucTcii, Guer.) ; Europe, Africa, 



Canaries, &c. 



7. niger, Aube ; Sicily, Madeiras, Canaries, &c. 



8. hipartitus, Woll. ; Cape Verde Islands. 



9. contractus, Woll. ; Japan. 



With these few preliminary observations, the four species from 

 Japan, which I believe to be undescribed, may be characterized thus : — 



§ I. AntenncB Q-articulatcB ; articulo 3'*" sequentibus distincte longiore. 



HOLOPAEAMECUS ELLIPTICUS, U. sp. 



H. ellipticus, convexiusculus, vel rufo-ferrugineus vel rufo-testaceus, sub-nitidus, 

 {oculo fortissime armato) subtilissime et parce ^yuiescens, uhique suh-ohsolete punctu- 

 latus ; oculis sat prominentihus ; prothorace suhcordato-quadrato (postice paululum 

 angustiore, ad latera oblique sub-recto, angulis posticis sub-rectis), basi in medio 

 leviter t/ransversim impresso (parte basali fovea longiusculd utrinque terminatd, necnon 

 carinuld medid brevissimd teiiuissimd subdivisd) ; elytris sub-ellipiicis, singulis strid 

 suturali redd leviter impressis. Long, corp. lin. visa f . 



In the two examples from which the above diagnosis has been 

 compiled, the antennae are 9-articulate ; but whether the opposite sex 

 (assuming these individuals to belong to one and the same) has those 

 organs composed of ten joints (as is the case in the Kunzcsi, Aube, 

 and the singularis, Beck), I am unable to say. At any rate, even if it 

 be so, the species is totally distinct both from the Kunzcsi and the 

 singularis (the former of which, so widely distributed over the world, 

 was also met with in Japan by Mr. Lewis), being well defined by its 

 rather convex and elliptical elytra and its somewhat quadrate pro- 

 thorax (which is only slightly narrowed behind, and a good deal 

 straightened, though oblique, at the sides, with the centrally-divided
