ceps," and one of whose midshipmen was the distinguished Arctic 

 explorer, Sir John Franklin. 



These two insects should be placed in a new genus ; but shortness 

 of time and other reasons force me to refer them to Platysma, or 

 I* evens. Mr. Ford's admirable figures will make them known. 



Aulacopris, White. 



AULACOPRIS REICHII. (PL LVIII. fig. 5.) 



A. aterrimus ; thoracis dorso carinis decern elevatis longitudina- 

 libus, quatuor antice et sex postice positis ; elytris muricatis, 

 singulis seriebus tribus longitudinalibus tuber culorum. 



Hab. In ripis fluvii Yarrse (Australia). 



Mr. Bakewell kindly gave the Museum this fine new species, which 

 I have named in compliment to my excellent friend Mr. Reiche of 

 Paris, who has studied the Lamellicorns so much and described 

 them so well. I remember seeing his fine collection in 1841. This 

 is one of the Minthophilides of Lacordaire's third volume, in Sec- 

 tion 2, where the pygidium is covered by the elytra. It has a 

 broadly notched lobe on the front of the head, the surface of which 

 is punctured. The femora of the fore legs have a strong, ridged hook 

 on the under side. The deeply grooved thorax has its grooving 

 produced by four elevated ridges on the fore part and six shorter 

 ridges behind, the two portions separated by a transverse groove 

 extending from side to side. The edges of the thorax are crenulated ; 

 on each side of the Ryboma-sh&pe& elytra are four rows of pointed 

 tubercles. The tarsi of the hind legs (the specimen is deficient of 

 the tarsi of the other legs) are nearly *>qual in width throughout. 

 The inside of the hind tibise is crenulate or tubercled. All the 

 femora are two- keeled below. The pectus of the metathorax is 

 grooved on the hinder edge, and ends in a ridge. 



We have only one specimen. It is a most remarkable Australian 

 form of the family Copridce. 



Oryctes. 



Oryctes mulleranus. (PI. LVIII. fig. 4.) 



O. IcEvigatus, brunneo-niger ; thor ace v aide dilatato, dor so v aide 

 cuvato, margine antico ad medium cornu apice subfurcato 

 a?'mato, lateribus singulis cornu crasso angulato armatis. 



Hab. In Australia sept. (Fitzmaurice River). 



This remarkable Beetle, with its much dilated thorax hollowed 

 deeply out on the back, and with a somewhat recurved, slightly 

 forked, projecting horn in front, and a short, angled, strong upstand- 

 ing horn, like a truncated snag-front, was found by the distinguished 

 botanist Dr. Miiller, on the Fitzmaurice River, N. Australia, during 

 Mr. Gregory's exploration, on Oct. 18, 1855, as the late Mr. Elsey 

 told me. Dr. Midler's able papers in the Linnean Society's ' Pro- 

 ceedings ' must be valuable additions to Botanical science.
