one on the centrQ of the sutural margin, also partly on each 

 elytron ; between this last and the humeral spots is one on the 

 disk of each elytron, and, finally, between each exterior marginal 

 spot and the apical one is another, on the disk of each elytron. 

 Beneath, the insect is black, and very glossy, with the exception 

 of the throat, which is pale : legs fusco - ferruginous, meso- and 

 metafemora nearly black. (Length 1^ lin.) 



This insect is, I believe, also unique in the cabinet of 

 Mr. Wailes : in beauty it exceeds any of the tribe I have 

 ever seen. Mr. Wailes transmitted it to me with a MS. 

 name, decern maculata, a name I have somewhat uncour- 

 teously superseded, although I must allow it to be exceedingly 

 appropriate and descriptive; ray only objection to it was its 

 length. 



Genus. — Rhyzophagus. Herbst. 



Rhyz. collaris. Ferrugineus, thorace fusco. 



Entirely ferruginous, with the exception of the prothorax, which is 

 fuscous. (Length 1| lin.) 



This species has been taken in considerable abundance by 

 Dr. Howitt, and liberally distributed by that gentleman, with 

 a MS. name, R. cadavet'inux attached, a name which appears 

 to me to convey rather an incorrect idea, Dr. Howitt having 

 taken it from the wood of old coffins, and the genus being 

 essentially wood feeders. 



Natural Order. — Bostricites, ined. 



Genus. — Rhyzopertha. Stephens. 



Rhyz. cincta. Nigra ; prothoracis margine posteriori, 

 elytrorumque disco testaceis. 



Head black ; antennae testaceous ; prothorax black, with the pos- 

 terior portion testaceous, giving the insect a belted appearance ; 

 elytra testaceous, with a wide exterior margin, black ; legs tes- 

 taceous. (Length l^ lin.) 



This insect is, I believe, unique in the cabinet of Mr. 

 Wailes.
