from St. Helena. 209 



A single specimen (a female) of this fine Calosoma was taken by 

 Mr. Bewiekc at St. Helena. In its obscurely brassy and rugulose 

 upper-surface it belongs to tbe same type as the African species 

 C. Senegal ense and rugosum ; nevertheless from the former of these 

 it is abundantly distinct. With the latter, judging from the descrip- 

 tion, it is much more nearly allied ; though I am informed by Mr. 

 F. Smith, who has kindly compared it for me with examples in the 

 British Museum, that it is not only more depressed and with the 

 coppery punctures smaller, but that the prothorax is more deeply 

 rugose in front and behind, and that the legs are slenderer and with 

 the pile on the underside of the feet veiy much softer, — being, in 

 fact, fine hairs, instead of stiff bristles. Apart from the characters, 

 however, which separate it from the Q. rugosum in particular, I may 

 just add, that its very small and short prothorax (which is almost 

 equally rounded before and behind, and has its posterior angles, 

 although backwardly produced, very obtuse), in conjunction with its 

 transversely-imbricated and equally -convex elytral interstices and 

 its shortened limbs (at any rate in the female sex, of which I can 

 alone speak), should be especially noticed.

Three specimens of this insect were taken by Mr. Bewicke at 

 St. Helena ; and I have seen another, from the same locality, in the 

 collection of Mr. Fry. It is a species of Mediterranean latitudes, 

 occurring in Portugal, Spain, the south of France, Italy, Sicily, 

 Egypt, and the coast of Barbary ; and one which also abounds in 

 most of the Atlantic islands. It is said to be common throughout 

 the Azorean archipelago ; and I have myself captured it in Madeira 

 and Porto Santo, as well as in Lanzarote, Teneriffe, and Palma (of 

 the Canaries). It is recorded by Dejean as having been found even 

 in Chili.
