404 OANARIAN COLEOPTEKA. 



The C. gemina has been observed hitherto only in TeneriiFe and 

 Palma ; in the former of which it is rather common — occurring in 

 many districts and at various altitudes, and attaching itself to very 

 opposite kinds of plants. Thus, in Teneriffe it was captured by Mr. 

 Gray and myself, near the Puerto Orotava, during January 1858, 

 almost exclusively on the Lavandula ahrotanokles ; whereas in the 

 woods above Taganana it seems to prefer a species of Bystropogon 

 (after the fashion of the curious C. onycMna of Madeira), where I 

 have seen bushes of that plant absolutely sparkling with it. And I 

 have also met with it around the roots of Euphorbias on the moun- 

 tain-slopes forming the northern side of the Barranco do Passo Alto, 

 near S'''' Cruz, as well as at the Agua Garcia and the Agua Mansa. 

 My Palman specimens are from the Barranco above S*''' Cruz of that 

 island. Examj)les from Teneriffe have also been communicated by 

 the Barao do Castello de Paiva and Dr. Crotch ; in which island it 

 was likewise met with by my friend the late Rev. "W. J. Armitage.

Although it does not entu'ely agree with his diagnosis, I think it 

 is far from improbable that this insect is the ChrysomeJa rufipes of 

 M. Brulle ; nevertheless, since the specific title of rufipes was already 

 preoccupied in the genus ChrysomeJa by De Geer, M. BruUe's name 

 would of necessity have to be suppressed — which is the less to be 

 regretted since I am by no means certain that the present Phcedon is 

 absolutely identical with his insect *. 



The P. menthce may readily be known by its bright- aeneous, densely 



* Thus, he speaks of " le corselet obseur," which does not in the least apply to 

 the P. menthce, wliere the entire surface is uniformly wneous and equally sJiining 

 tliroughout. Then, he omits all alkision to the dense (though light) punctation 

 of its whole upper surface ; though, as it is his habit to avoid noticing the most 

 distinctive features of his several species, citing those only wliich are common to 

 all of the same gi'oup, I lay but little sti-ess upon tliis latter circumstance.
