in consequence of the observations of Germar and Schonherr, 

 it may be as well to give as complete a table as we can of the 4 

 species that inhabit Britain, especially as we do not entirely 

 coincide in the opinion of Germar. 



1. M. Cerasi Linn., GylL, Germ., Schon. — carbonarius' Paw;^. 



42, 18. — Armeniacae Fab. 

 Found in June upon the leaves of Prumis Padiis and Cera- 

 sus, as well as the Pear, eating the epidermis and marking 

 the leaves with spots. 



2. M. Carbonarius Linn. — Gyll. 3, 185, 101. /m. — Oliv.? 



V. 5. pi. 34. yi 518. — aterrimus Herbst. male. — atra- 



mentarius Marsh, male. Germ., Schon. — atratus Gyll. 



3. 187. 102. male. 



June : on Plum, Birch, and Nut trees. Of this insect, which 



is by no means common, I took a pair upon a Hazel-tree near 



Ambleside the 19th of last June; and there is no doubt but the 



C. atratus of Gyllenhal is the male of his C. Carbonarius, 



which does not appear to be different from the C. Carbonarius 



of Linnaeus : the insect figured is a female. 



3. M. Stygius Marsh., Gyll., Schon. — Cerasi Oliv. 5. tab. 22. 



f. 309. — Herbst. Clairv.? — aterrimus? Fab. 

 June : Cherry and Sloe trees in hedges. The Marshamian 

 name has been retained, since it is doubtful whether it be the 

 C. aterrimus of Fabricius; for it certainly is not the C. aterri- 

 mus of LinnsRus to which he refers. 



4. M. Pruni Linn.y Fab., Gyll., Oliv., Marsh., Germ., Schon. — 



erythroceros Herbst. — incognitus Herbst. — ruficor- 



nis Schr. 

 The larva of this species is said to be gelatinous and lima- 

 ciform (viz. like a Slug), and is found as well as the Beetle 

 upon the leaves of Primus Padus and Cerasus, the latter of 

 which species, the Cherry-tree, accompanies the insect.
