eyes. I have also given a careful representation of the maxilla and the ante- 

 rior tibia, showing the peculiar construction of the subapical notch ; and have 

 added a figure of the underside of the head with the various organs in situ, 

 from which it will be seen that there is a curved elevated line across the 

 middle of the produced central part supporting the mentum, but I very much 

 doubt whether there be any actual articulation at this place. On each side 

 of this central part is a deep impression, having an elevated ridge running 

 down the middle, forming two deep canals on each side, the interior of which 

 serves for the action of the base of the maxilla, whilst the external forms a 

 fossula for the concealment of the antenna when withdrawn beneath the 

 head. 



In the " Iconographie des Col^optferes" of Messrs. Dejean and Boisduval 

 (vol. i. p. 176) a genus was proposed under the name of Axinophorus, consist- 

 ing of two species, A. Lacordairei and A. Lecontei, the former inhabiting 

 the vicinity of Rio Janeiro, and the latter North America. In the Supplement 

 to the Species G^n6ral, Dejean having ascertained that this new genus was 

 identical with Pseudomorpha as well as with the genus Drepanus, indicated 

 only by Illiger in the sixth volume of the " Magazin der Entomologie" (p. 344), 

 republished his descriptions of the Accinophori under the generic name of 

 Drepanus, giving A. Lecontei as probably identical with Pseudomorpha ex- 

 crucians, K. On comparing the figure given of A. Lecontei in the Icono- 

 graphie with the authentic specimen of Pseudomorpha excrucians, now in the 

 collection of the Entomological Society, it is unquestionable that they are 

 specifically identical, so that the name Lecontei must sink into a synonym ; 

 and in like manner I feel disposed to preserve the generic name proposed by 

 Mr. Kirby in preference to that merely indicated by Illiger. 



In the first part of the Transactions of the Entomological Society, a still 

 more remarkable insect was described by the Rev. F. W. Hope, under the 

 name of Adelotopus Gyrinoides, being doubtfully placed in the family Gyri- 

 nidce, with the observation : " This singular insect was sent to me from the 

 Swan River Settlement in New Holland. It seems to unite in itself the 

 characters of several families. From the tarsi it is referrible to the Penta- 

 mera ; whilst its general appearance and clavate antennae place it amongst 

 the Necrophaga. By its subcontractile legs (for the bent tibiae are not en-
