loose articulations. The front of the corslet presents no de- 

 pression. 



Necrohia violacea^ Oliv. Col. ibid. 76, his. I, 1 ; Dermestes 

 violaceus^ Lin., is small, of a violet or greenish blue, with feet 

 of the same colour. Its cases have points disposed in longitu- 

 dinal series. It is very common in spring, in houses. It is 

 also found in carrion. (*S'ee Olivier, genus Necrohie, and 

 Schoenh. Synon. Insect. I. 2, page 50.) 



We shall terminate this tribe by a sub-genus, in which the 

 two last but one articulations of the antennae, more or less 

 dilated at the internal side, in the manner of teeth, compose, 

 with the last, which is ovaliforra, a serrated or semi-pectinated 

 knob. The palpi are terminated by a larger articulation, 

 either in the form of an elongated and compressed triangle, 

 or hatchet-formed. Such are

The fifth tribe of the Malacodermi, that of Pthstiores, 

 has for type the genus Ptinus of Linnseus, and some others 

 which are derived from it, or approximate to it the most. 

 The body of these insects is of a consistence tolerably solid, 

 sometimes almost ovoid, or ovaliform, sometimes almost cy- 

 lindrical, but generally short, and rounded at the two ends. 

 The head is almost globular, or orbicular, and received for a 

 considerable part in a corslet, very much arched, or vaulted, 

 in the form of a hood. The antennae of some are filiform, or 

 proceed narrowing towards the end, whether simple, flabel- 

 late, pectinate, or serrated ; and those of the others are 

 terminated abruptly by three larger and much longer articu- 

 lations. The mandibles are short, thick, and denticulated 

 under the point. The palpi are very short and terminated
