Genera and Spech'S^ of Coleoptcra. 455 



This species is broader and nuich more depressed than Uloma 

 culinai'is, Linn., and the fore tibiae arc rather seriated tlian tootlied ; 

 the punctures on the elytra are also very much deeper and more 

 distinct. 



Dechius [Tenebrionina^]. 

 Tcnchrioni aflinis, sod difll-rt pni^cipiic lahro obtceto. Maxilhr lobo interim 



mutieo. Autcnnce articulis 8-10 trausversis. Prof/iora.r ibrtiter niar^n- 



natus, marginibus autice productis. 



The characters of Tenehrio, 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-iorm to justify the specific 

 name proposed. 



Dechius apliodioides. 

 D. fusco-ferrugineus, subnitidus ; capita prothoraceque fiisco-nigris ; ely- 



tris fortiter striato-punctatis. 

 Hah. Queensland. 



Brownish ferruginous, subuitid ; head and prothorax brownish black, 

 the edges of the clypeus reddish ferruginous, finely punctured, the pro- 

 thorax gi'ooved 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 ; antenna? extending to 

 about the middle of the prothorax, reddish brown. Length 4^ lines. 



ScTMENA [Trachyscelinae]. 

 Characteres ut in Phaleria, sed clypeus profunde quadrato-excisus. An- 

 tennce 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 Phcderia. The 

 type described below resembles P. Gayi, Lap. Of my two ex- 

 amples one is reddish testaceous, the other black. 



Scyniena variabilis. 

 S. rufo-testacea vel nigra, nitida ; elytris fortiter punctato-striatis, intor- 



stitiis striarum subtiliter punctulatis. 

 Hub. Australia. 



Shortly ovate, reddish testaceous or black, shining; head finely 

 punctured ; clypeus separated from the fi-ont by a well-marked semi-
