bles it in tlie relative proportions of the thorax and elytra, but is altogether as distinctly 

 elongate and slender as L. geminum is robust and broad. Tn L. fulvipenne also the pen- 

 ultimate segment of the male beneath is quite destitute of haiiy ridges, having simply 

 a shallow and somewhat oval excision in the middle of the hinder margin. The punc- 

 tuation of the under surface of the head is much the same as in L. geminum, but the 

 general facies of the insect will at once distinguish it. 



" Erichson appears to have remarked the difference in structure of the present 

 L. geminum, but referred it to a var. of L. elongatum, Linn." 



Mr. Crotch exhibited Dermestes Frischii, Kugelan, and read the following 

 notes : — 



" Dermestes Frischii, Kugelan, Erichson, = D. vulpinus, Illiger, non Fah. 



"This species, hitherto unrecorded as British, was taken somewhat plentifully by 

 Mr. W. Farren, of Cambridge, under a dead horse in the New Forest, in the early 

 part of the summer of 1860, in company with Dermestes murinus; hence it would ap- 

 pear to be a truly indigenous species, whereas D. vulpinus is in all probability 

 introduced. 



" It most closely resembles D. vulpinus. Fab., from which it may be distinguished 

 by the brighter colouring of the pubescence on the sides of the thorax, which is 

 also conspicuously marked with a black spot at each hinder angle. Underneath, the 

 middle spot on the last segment of the abdomen is purely terminal, whereas in 

 D. vulpinus, Fah., the spot is produced for the entire length of the segment. In D. 

 vulpinus. Fab., the apex of each elytron forms a small acute mucro, which is entirely 

 wanting in D. Frischii. The scutellum also appears to be of a much brighter yellow 

 in D. vulpinus. Fab. 



" It may be as well here to observe that the insect termed Dermestes tessellatus of 

 Waterhouse's Catalogue is evidently the D. uudulatus of Erichson and Sturm, and 

 Mr. Waterhouse agrees with me in this opinion.''
