Although hitherto efteemed a rarity among the entomologifts of this country, Lucanus .Eneus appears 
to be by no means unfrequent in fome parts of the ifland of New Holland j we have lately feen, for 
inftance, a parcel of them brought from that country, amounting to not lefs than fifty fpecimens, 
all which were colledted in the environs of the Englifli fettlement at New South Wales. The fpecies has 
thus become pretty common now in England. When Fabricius defcribed it, this infefit, on the contrary, 
was extremely rare, the only fpecimens of it known in this country, or perhaps in Europe, being at 
that time in the Bankfian cabinet; for the fpecies was originally difcovered in Norfolk ifland, in the Pacific 
Ocean, by Sir Jofeph Banks. Fabricius did not certainly examine this infedt with his accuftomed accu- 
racy and critical difcrimination, or he would not have afligned it to his new genus Lethrus, (the firft in 
his clafs Eleuterata) fince it is moft alfnredly a Lucanus of the Fabrician, as well as the Linnaean Syfiem. 
The figures of this infedt in the annexed plate exhibit two very firiking varieties of this fpecies, one 
being of a fine golden colour, and the other a dark green. Of the latter kind fome other fpecimens have 
occurred to our obfervation in which the colours varied from a dark green to blue, or at leaft blueifli. 
The fpecimens in the cabinet of Mr. Francillon are from Norfolk Ifland. 
LUCANUS. PARVUS. 
SPECIFIC CHARACTER. 
Brown: jaws exl'erted, and toothed on the outfide: head fmall: thorax large and canaliculated : wing- 
cafes ftriated, 
Lucanus Parvus : brunneus, mandibulis exfertis extus dentatus, capite parvo, thorace magno, cana- 
liculato, elytris ftriatis. 
A new fpecies of Lucanus, but of a diminutive fizc compared with the reft of the infetls in the fame 
genus, and in allufion to which we have named it parvus. Mr. Francillon is in poftTeflion of this curious 
infedt, which he received from New Holland.
