50 CANARIAN COLEOPTEEA. 



to me that the insect which he referred to the F. harbara of Dejean 

 must have been the nearly allied (though scarcely coincident) P. lon- 

 gulus ; and that consequently his F. canariensis (which immediately 

 follows it) was of necessity something different. Now, his comparison 

 of the latter with the Pyrenaean Argutor ahaamdes, and the differential 

 charactei's which he draws between the two, utterly preclude the idea 

 that his F. canariensis could possibly have been the species which I 

 have just described as the longulus of Reiche ; whilst the very few 

 points to which he calls attention are all in favour of its tallying 

 with the male (for he expressly mentions it as " luisante ") of the 

 present Pterostichiis. Indeed (the P. longulus disposed of) there is no 

 Canarian insect to which his " description" could apply except the 

 present one ; and I think therefore that I am fully justified in treating 

 his C. angnlaris and F. canariensis as identical*. Assuming them 

 therefore to be coincident, I have preferred the former specific name 

 to the latter, as the more appropriate of the two, — the insect being 

 found, apparently, in but one of the seven islands of the Group. 



The P. angularis is universal throughout the sylvan regions of 

 Teneriffe. During March of 1858 I took it abundantly, in coitu, at 

 the Agua Garcia ; and it is also common at Las Mercedes, and in the 

 forest above Taganana. It has likewise been coramimicated by the 

 Barao do Castello de Paiva ; as also by Dr. Heer (from the collection 

 of M. Hartung).

* It is much to be regretted that M. Brulle should not have been a little more 

 accurate in his descriptions. Apart from all other characters, if he had looked 

 at the claws of his C. ang^ilaris he would have immediately perceived that it was 

 no Calathus at all ; and at least one of his diagnoses (all equally unintelligible) 

 would have been thus removed into its frofer place, — enabling after-observers at 

 all evenfs to (/uess wliat the insect really was to which he referred. His total 

 silence too as to the exact islands in which the several species occur (thovigh all 

 the types which I examined in Paris, of MM. Webb and Eerthelot, had their 

 islands indicated by a separate label) deprives us of t^e only possible clue which 

 we might have otherwise had for deciphering his insects.
