A NEW SPECIES OF LACCOBIUS.

Laccobius ytenensis, sp. n.

Mas. : labro anterius fencstris vitreis dvabus magiiis, pariim distantthus, 

 ornato. 



This species is a very distinct one, though it has apparently 

 escaped discrimination until now. The male character, of the labrum 

 having two lenses, or goggles, of large size and short-oval form, and 

 separated from one another by a rather less space than the transverse 

 diameter of one of the lenses, is in itself sufficient to characterise the 

 insect. In several members of the genus the males have no goggles, 

 and in none of the species in which this peculiar structure is 

 exhibited are the lenses similar in shape, and so little separated. 



The species has no spot of pubescence on the middle femur of 

 the male. It must be placed between L. ohlongus, Gorh., and 

 L. regularis, Rey. 



L. ytenensis occurs in great profusion in the New Forest during 

 the month of September. Outside our district, I know it by a small 

 series found by Mr. Philip de la Garde in Devonshire, and a single 

 specimen from Padstow (C. G. Lamb) ; Mr. Champion has also found 

 it, very sparingly, in Devon and Cornwall. It is the insect I liave 

 given previously to various friends as " L. sinuahis," but it is certainly 

 not the species Motschoulsky had in view when he proposed that name. 



L. ytenensis varies a good deal in size, and in the colour of the 

 posterior femora ; these are usually extensively clouded with black, 

 but are sometimes quite yellow. The maculation of the elytra is also 

 subject to slight variation.
