IS MANDIBULATA. — -COLEOPTEBA. 



priety of considering every unrecorded insect to be either rare or 

 uncommon f. Would not he who were to affirm that Lucanus 

 Cervus was a scarce species be justly ridiculed? Yet were an en- 

 tomologist located in certain situations near the metropolis, he would 

 experience much difficulty in procuring specimens, as, although 

 found abundantly in the county, I have never seen a single one 

 in the vicinity of Hertford during fifteen years' research, though I 

 have assiduously toiled, from " morn to dewy eve," in the capture 

 of the insects indigenous to that part. 



Since the above observations were penned I have obtained several 

 specimens of this species, chiefly captured in the immediate vicinity 

 of London, thereby affording another proof of the importance of a 

 thorough investigation previously to asserting that a recently de- 

 tected insect is of unfrequent occurrence ; and I cannot here avoid 

 noticing, as bearing upon the point, that in consequence of my 

 observations upon Cicindela hybrida and its affinities, my friend 

 E. T. Bennett, Esq. F. L. S., &c. exhibited to me several specimens 

 of an insect which appear to correspond with the Ci. hybrida of 

 Latreille ; — they were given to him by Mr. Leyland of Halifax, 

 and he kindly presented me with a specimen. I have subsequently 

 applied to Mr. Leyland for information respecting their locality, 

 &c. and in reply he obligingly favoured me with several individuals, 

 which he informs me were captured in Lancashire, he believes in 

 the neighbourhood of Preston. As they differ considerably from 

 Ci. riparia, and the other allied species which I have noticed, I 

 shall embrace the present opportunity of briefly introducing the 

 description of them, accompanied with some remarks upon their 

 congeners, as I shall give the necessary reference thereto in my 

 systematic catalogue.

 The upper surface of the typical variety of this beautiful insect is usually of a 

 rich silken purple or reddish-copper tinged with green, with iridescent re- 

 flections on the head and thorax ; the elytra are rather convex, shagrcened, 

 or granulated as in the other species, and each ornamented with a whitish 

 lunule at the base and tip, and a slightly waved, transverse, abbreviated bar 



t In the Literary Gazette of 11th of March, 1827, the capture of a new 

 British Cychrus is cxultingly announced as a valuable novelty, whereas the 

 specimen alluded to proves to be merely the female of the common C//. rosfrafux !
