This curious insect may be placed near Onthophilus. The 

 anterior angle of the thorax, viewed from above, seems angu- 

 lated, in the same manner as in Hetcerius hispanus, Modems, 

 and others ; but when viewed from the front this protube- 

 rance is seen to be the superstructure of a large cavity which 

 occupies the greater part of the elevated thoracic ridge. In 

 this cavity the whole of the antennas can be lodged, having 

 at the same time space for movement, and when the antennas 

 are thus stored, club first, the large basal joint fits into the 

 orifice and effectually closes it. In Chlamydopsis, the basal 

 joint of the antenna? covers the funiculus when in a state of 

 repose, but leaves the club visible. Teratosoma is a Myrme- 

 cophilous species ; but while being able to effectually protect 

 the antennas when disturbed or enjoying repose, Nature lias 

 made no provision for the protection of the long legs, which 

 are often contractible in members of this family. The long 

 legs are doubtless of the greatest value in securing rapid 

 movement, and the fore tarsi are very short and can rest in 

 the tibial grooves ; but in the other legs the recesses are too 

 shallow to afford much security. The hind femora are 

 bowed in such a manner as to enable the insect to raise them 

 perpendicularly. 



Chlamydopsis inquilina, n. sp. 

 Castanea, gibba, subnitida ; fronte opaca, rugoso-punctata , pronoto 

 transverse*, nitido, margine acute elevato, parce obsoleto-punctato ; 

 elytris subnitidis, fere ut in O. striatella, parce setulosis ; pedibus 

 elongatis, pube adpressa vestitis ; propygidio pygidioque dense 

 griseo-hirsutis. L. 3| mill. 



Hab. Australia (Duboulay). 



C. inquilina may be known from diiboulai (sic) by its larger 

 size and transverse thorax, which is acutely and evenly 

 elevated both in front and at the sides. From striatella it 

 differs in its longer and more robust legs, and shining thorax 

 with large, shallow, indistinct punctures, and the elytra are less 

 elevated in the region of the scutellum. The propygidium and 

 the pygidium are clothed with long griseous hairs, and the 

 legs are covered with a short dense pubescence. 



The genus Chlamydopsis should be placed near Onthophilus. 



Onthophilus foveipennis, n. sp.
