the posterior margin greatly thickened ; each plate with two lunate deep impressions 

 close to the margin, and extended across the segment. Legs very hairy, with the thighs 

 large and strongly spined. Posterior pair of legs very strong.

Head orange-coloured ; the eyes, sides and front with a blackish fascia ; eyes large. An- 

 tennae with forty joints, hairy, yellow. Mandibles and labium bright yellow. Meta- 

 tarsal joint hairy, orange. Femoral and tibial articulations with short spines. 



This is the smallest of the British species. It was taken by myself at Sand- 

 wich, during a continuance of dry weather, under moist stones in a garden, in 

 the month of September 1842, but I have not met with it since, and it appears 

 to be rare. I possess four specimens. It is very distinct from other species, 

 especially in regard to the excavations in the coxae, which, instead of being 

 simply transversely furrowed, have each four oval, cup-shaped bodies within 

 them. The largest of the species does not exceed six-tenths of an inch in 

 length.

The above character is derived from an inspection of Savigny's figure in 

 the great work on Egypt ; but as no description of the plates has yet been 

 published, I have given the character with a query. M. Gervais* very justly 

 remarks, that the specimen figured was immature, as is shown in the small 

 number of ocelli and of joints to the antennse, there being only four ocelli 

 on each side, and twenty joints to each antenna. But notwithstanding this, 

 Savigny appears to have delineated a distinct species, if the figure he has given 

 is correct, and I see no reason to doubt it. I am not acquainted with any 

 other Lithobius that exhibits, in any stage of growth, that peculiar form of the 

 legs which characterizes Savigny's species.
