THESAURUS ENTOMOLOGICUS. 
ORDER—COLEOPTERA. 
Section—PENTAMERA. Famity—CARABIDZ. 
Grenus—DELINIUS. Westw. 
(Trans. Ent. Soe, Lond. 3rd Ser. vol. ii. Proc. p. 3.) 
Habitus et statura Steropi madidi. Antenne breves graciles, geniculate, articulo basali tertiam partem 
longitudinis oceupante. Caput mediocriter porrectum, labro in medio marginis antici prominenti. Mandibule 
graciles acute, intus edentate. Maxille spina rigida apicali lobi interni, margineque interno spinulis armati. 
Palpi maxillares externi articulo apicali medioeri, subsecuriformi. Mentum in medio emarginature porrectum 
truncatum. Palpi labiales magni, articulo ultimo magno securiformi. Prothorax subquadratus, lateribus rotun- 
dato-curvatis. Elytra ovalia. Tibie antic haud palmate, margine interno emarginate. 
This curious genus in its geniculated antenne might be considered to belong to the Scaritides ; its general 
affinities are however with the Harpalides, approaching Promecognathus and Eripus. It is placed in Harold 
and Gemminger’s Catalogue between Omaseus and Steropus. I am not acquainted with the Australian genus 
Meones of Castlenau (Notes on Austral. Col., p. 69), which is probably nearly allied to Delinius ; but it is 
described as resembling a large Stomis, but broader, with more oval elytra, and with triangular-formed palpi 
and filiform antenne. 
Species unica—DELINIUS ESSINGTONII. Westw. 
Prats II, Fie. 1. 
_ (Trans. Ent. Soc. Lond. loc. cit. supra, p. 3.) 
Niger subnitidus ; capite inter antennas bisuleato, pronoto suleo medio in fossulam parvam ovalem ante 
marginem posticum terminato; suleisque duobus prope angulos posticos notato; elytris striatis costaque sub- 
marginali instructis.

Habitat ; Port Essington in Australia. In Mus. Hopeiano Oxonie. 
Plate II, fig. 1 a, represents the head and antenna of this insect seen from above; and 14 as seen from 
below, shewing one of the maxillary and one of the labial palpi: fig. 1 ¢ represents one of the maxilla; and 1d 
the mentum, labium, and one of the labial palpi. 
Famity—CETONIID. Sus-Famity—GOLIATHIDES. 
The whole of the then known species of this sub-family, of which many are remarkable for their large size, 
brilliant colours, or the horns with which the head and sometimes the thorax of the males are armed, were 
illustrated in the ‘ Arcana Entomologica ;’ since the publication of which work some few additional, but equally 
interesting species, have been obtained. The larger species are natives of tropical Africa, from which country 
» the whole of those represented in Plate I. have been received (except fig. 4).
