8 MANDIBUI.ATA. — COLEOPTERA. 



Sp. 2. hybrida. Suhpiirpurascens, elytris lunula humerali api- 

 c'isque,Jascidque media valde deflexa, albis ; palpis labialihus hasi 

 nifo-albidis. (Long. c. 6 — 7 lin.) 



Ci. hybrida. Linne. Sowerhj. i. plate 18. — Steph. CataL No. 2. 



Above fine purplish, or dull iridescent copper ; each elytron finely shagreened, 

 and marked with a white external lunule at the base and tip, and a trans- 

 verse, waved, and strongly deflexed band in the middle : the suture bright red- 

 copper. Beneath, the sides of the thorax and breast, are splendid rufous- 

 copper : the abdomen rich and brilliant green-blue : thighs and shanks red- 

 copper ; tarsi green blue : labrum whitish : maxillary palpi bronzed-green ; 

 labial palpi reddish- white, with the terminal joint bronzed-green. 



This species is subject to considerable variation, both in colour 

 and markings ; but in all the varieties the labial palpi are reddish- 

 white at the base, and the maxillary palpi are brassy-green, with a 

 rufous tinge at the joints of the articulations. In these points this 

 insect materially differs from Ci. Sylvicola, which it otherwise 

 closely resembles, excepting in colour, and in the form of the 

 central fascise on the elytra, which in this reach transversely to the 

 centre of the disc, then become suddenly deflexed and attenuated, 

 and finally, after again expanding, terminate abruptly near the 

 suture. 



In pronouncing this to be the true Ci.hyhrida of the Fauna Suecica, 



I am guided by the following words of the illustrious Swede : 



•' color purpurascenti-fuscus. Elytra in medio fascia alba, undata, 

 simtli sequentis speciei (Ci. sylvatica) et ad marginem exteriorem 

 baseos, uti etiam ad apicem, lunula alba,'''' — as they so perfectly 

 express its peculiar colour and markings. 



Much confusion occurs in modern entomological works respecting 

 Ci. hybrida and its congeners, which has given rise to contrariety 

 of opinion respecting the true habitat of this species. Latreille, 

 in his Histoire Nat. des Crust, et des Insectes, &c., observes, that 

 it is common in the neighbourhood of Paris ; but from the recent 

 publication * of this learned entomologist, and his compatriot De 

 Jean, it is evident that the insect called Ci. hybrida by them is 

 totally distinct from the present, and appears intermediate between 

 Ci. riparia and Ci. Sylvicola, and that the species now under con- 

 sideration is their Ci. maritima, which is confined to the coasts^ of 

 France, as our insect is to those of Britain ; and on the extensive
