much larfjer insect than Clanibus Enshamensis ; and in Dr. Sohaum's ' Catilogue,' 

 1859, p. 37, we find the two genera given as distinct, Fairmaiie's genus Comiiztis 

 being used for our British insect. 



"In the fifth volume of the 'Illustrations' Stephens adds two other species of 

 Clambns to our list, viz. : — 



" C. niiriclavu, Rudd, MSS. (represented by a single specimen in the collection), 

 which is the C. minutus, Sturm., Fairin., ^-e. = C. Armadilhis, Redt. 



" C. nitidus. I find no specimen hearing this name in the collection, and from the 

 extremely brief description I am unable clearly to identify the sjiecies. 



" Lastly, Stephens describes two species of the present genus amongst the species 

 of Agalhidum, viz., A. minutum = A. uiinutum, Slurm.; and A. uanum = Chimbus 

 Armadillus, Fairmaire, SfC. 



" Of the genus Clambus, as now restricted, I have met with three species pretty 

 plentifully in the vicinity of London : I luave seen no other British species. They are: — 



" L Clambus minutus (Agathidium minulum), Sturm. This is the largest of our 

 species, and is readily distinguished by an alnmst total absence of pubescence on the 

 upper parts ; hence it appears much more glossy ; its colour, is pitchy black : the tho- 

 rax is margined with rufo-testaceons, narrowly before and behind, but considerably 

 extended on the sides of the thorax : the elytra very commonly have a bright rufous 

 spot on the disk. The legs and antennae are pale testaceous. 



"2. C. Armadillus, DeGeer, Fairm. et Lab. Black; clothed (not very densely) 

 with longish pale hairs ; sides of the thorax very narrowly and indistinctly edged with 

 testaceous ; body beneath entirely black ; auteunoe and legs more or less dusky ; the 

 tarsi pale. 



" 3. C. piibescens, Redtenbacher. This is the smallest of the three species : it is 

 distinguished by the upper parts being densely clothed with pale ashy pubescence 

 (hence the insect has a somewhat dull appearance) ; the colour is black, but the apex 

 of the elytra and the abdomen are more or less pitchy ; the pale colour on ihe sides of 

 the thorax is more extended than in the preceding species, and the legs are entirely of 

 a very pule testaceous colour; the antennae are also pale, with the exception of the 

 club, which is somewhat tinted with brown. 



"The form of the head likewise difi'ers in these insects; and with regard to the 

 last-mentioned species, I would call attention to the larger size of the eye, when com- 

 pared with the preceding : here it occupies nearly the whole of the lateral lobe of the 

 head, which is marked off by the antennal notch." 



The following papers were read : —

 R. W. Stretch, Esq. ; with a List of the described Species, and the various Localities 

 where they have previously occurred," by Mr. Frederick Smith. 



Part 8 of the current volume of the ' Transactions,' recently published, was on the
