Note on the British Species of Clambus. 



" The species of Clambus described in the second volume of Stephens's ' Illustra- 

 tions ' are : — 



"1. Clambus Armadillus. The description appears to me to belong to Agathi- 

 dium minutum of Sturm (= Clambus minutus, Fairm. et Lab. = C. Armadillus, 

 Redt.), but -C. Armadillus of Stephens's collection is identical with 0. Armadillo of 

 Fairm., and it is from this latter insect I have no doubt that the figure in the ' Illus- 

 trations ' is taken. 



"2. Clambus coccinelloides (Kirby JMSS.) is represented in Stephens's collection 

 by a specimen of Chaetarthria seminulum. ' I possess a single example of this insect, 

 which was kindly given me by the Rev. W. Kirby' (see Steph. Illustr. ii. p. 184). 



" 3. C. Enshamensis, Steph. Illustr. and Collection. This is identified (and, as it 

 appears to nie, correctly) with Scaphidiura dubium of Marsh am (Ent. Brit. p. 234) by 

 Mr. Wollaston : it is the Calyptomerus dubius of Wollaston's ' Catalogue of the Co- 

 leopterous Insects of Madeira,' C. Enshamensis of Jacquelin Duval's ' Genera des 

 Coleopteres d'Europe,' and Comazus Enshamensis of Fairm. et Laboulb. Notwith- 

 standing that there are certain discrepancies, when the characters laid down by Redt- 

 enbacher for his genus Calyptomerus are compared with those which are displayed by 

 Clambus Enshamensis of Stephens, it has been supposed that they were really taken 

 from the same insect. We are informed, however, in the Berlin Ent. Zeit. 1857, p. 

 174, that Calyptomerus alpestris of Redt. (the only known species of the genus) is a 

 much larger insect than Clambus Enshamensis ; and in Dr. Sohaum's ' Catalogue,' 

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

 being used for our British insect. 



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

 Clambus to our list, viz. : — 



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

 which is the C. minutus, Sturm., Fairm., i)-c. = C. Armadillus, Redt. 



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

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



^' Lastly, Stephens describes two species of the present genus amongst the species 

 of Agathidum, viz., A. minutum = A. minutum, Sturm.; and A. nanura = Clambus 

 Armadillus, Fairmaire, ^-c. 



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

 plentifully in the vicinity of London : I have seen no other British species. 

 They are: — 



" 1. Clambus minutus (Agathidiura minutum), Sturm. This is the largest of our 

 species, and is readily distinguished by an almost 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-testaceous, narrowly before and behind, but considerably 

 extended on the sides : 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 ; antennse and legs more or less dusky ; the 

 tarsi pale.
