Genera and Species of Coleoptera. 455 
This species is broader and much more depressed than Uloma 
culinaris, Linn., and the fore tibiz are rather serrated than toothed ; 
the punctures on the elytra are also very much deeper and more 
distinct. 
Decuivs [Tenebrionine ]. 
Tenebrioni affinis, sed differt preecipue labro obtecto. Mazille lobo interno 
mutico. Antenne articulis 8-10 transversis. Prothorax fortiter margi- 
natus, marginibus antice productis. 
The characters of Tenebrio, like those of perhaps the majority of 
the genera of Coleoptera, were only exposed in a really definite way 
in the ‘Genera’ of M. Lacordaire. Compared with his description, 
the above formula differentiates the two genera. The habit, more- 
over, is somewhat different, being more convex and cylindrical, and 
sufficiently suggestive of the Aphodius-form to justify the specific 
name proposed. 
Dechius aphodioides. 
D. fusco-ferrugineus, subnitidus ; capite prothoraceque fusco-nigris ; ely- 
tris fortiter striato-punctatis. 
Hab, Queensland. 
Brownish ferruginous, subnitid; head and prothorax brownish black, 
the edges of the clypeus reddish ferruginous, finely punctured, the pro- 
thorax grooved along the base, the raised margin bordering the groove 
depressed in the middle, where it is joined by the nearly obsolete 
median line; scutellum pentagonal; elytra a little broader than the 
prothorax at the base, strongly striato-punctate, the margins well 
marked, especially at the shoulders; body beneath dark brown, shining, 
the breast rufescent; legs reddish ferruginous; antenne extending to 
about the middle of the prothorax, reddish brown. Length 43 lines. 
Scymena [Trachysceline ]. 
Characteres ut in Phaleria, sed clypeus profunde quadrato-excisus. An- 
tenne capite breviores. Processus interfemoralis apice acutus. 
I have examined only the oral organs in situ; but they appear to 
be pretty nearly of the same character as those of Phaleria. The 
type described below resembles P. Gayi, Lap. Of my two ex- 
amples one is reddish testaceous, the other black. 
Scymena variabilis. 
S. rufo-testacea vel nigra, nitida; elytris fortiter punctato-striatis, inter- 
stitiis striarum subtiliter punctulatis. 
Hab. Australia. 
Shortly ovate, reddish testaceous or black, shining; head finely 
punctured; clypeus separated from the front by a well-marked semi-
