Lueanoid Coleoptera. 71 



lack of sufficient material to guide them, and we can- 

 not be surprised that errors in the definition of species 

 have so frequently occurred ; upwards of twenty dif- 

 ferent forms have been characterized as pertaining to 

 this genus by various authors, five of which can, I 

 think, alone be retained. L. sumptuosa, belonging to the 

 second section of the genus, was alluded to in my former 

 Catalogue as being a distinct species ; the brilliant 

 coppery coloration of the insect, differing so essentially 

 from that of the specimens of L. Micardi with which I 

 was then acquainted, caused me, after examining the 

 type specimen in the Hopeian collection, to consider it 

 as distinct ; since then, numerous examples of L. Micardi 

 have fallen under my notice, exhibiting the diversity of 

 development and colour to which I have above alluded. 

 On comparing recently, at Oxford, a specimen of L. 

 Micardi with the type of L. sumptuosa, Professor West- 

 wood and myself coincided in opinion as to the propriety 

 of uniting the two. The name Micardi has priority. In 

 reducing the number of species composing the genus 

 Lamprivia to five, I am supported by Count Mniszech, 

 in whose rich collection the finest series of specimens, 

 illustrating the different varieties of each species, may 

 be seen. 



Colophon Westwoodii, Gray. 



The Berlin Museum possesses both the ^ and ? of 

 this very scarce insect, six specimens of which have now 

 fallen under my notice; these are distributed as fol- 

 lows: — in the British Museum (the type specimen), the 

 Hopeian collection at Oxford, the Museum at Halle, my 

 own collection, and the two specimens at Berlin alluded 

 to above. The second species of this genus, described 

 by Professor Westwood, under the name Colophon Thun- 

 hercjii, remains unique in the Oxford Museum ; it is stated 

 to have been received from Caffraria. 



Fam. LucANiDiE. 



The family Lucanidce as constituted in the present 

 Catalogue, and restricted to the genera Mesotopus, Lu- 

 eanus, Pscudolucanus, Wioitus, and Hcxa.rthrius, I charac- 

 tei'ize as follows ; —
