The Irish Naturalist. 
August, 
informs us, in litt. that he has often seen specimens with 
28 antennal segments on both sides. As far as he has 
been able to make out Meinert's L. microps is a southern 
species, and lie did not recollect having secured a true 
L. microps except on the French Riviera (Cannes) where it 
is seldom found. Meinert's specimens probably originated 
from Spain and Algeria. Dr. Brolemann adds that L. 
Duboscqui and its near relative L. crassipes are common 
all over France. 
Mr. R. S. Bagnall gave a rough translation of the greater 
part of Dr. Brolemann's description when he recorded 
L. Duboscqui as new to Britain,' but we think it will be 
of some interest and value to Irish naturahsts to have 
the full description. 
LITHOBIUS DUBOSCQUI Brftlemann. 
(1896. Feuille des Jeunes Natnralistes, No. 306). 
Body very convex, smooth, shiny, almost parallel-sided or more or 
less narrowed in front and constricted behind the head, widest about the 
8th segment. 
Of a tawny colour, with the head inclining to reddish-brown and the 
limbs light-coloured, especially the two posterior pairs which are yellow- 
ochre or straw-yellow.

Cephalic shield subcordiform, with rounded posterior angles, and with 
a marginated posterior border. Antennae very short, composed of 23 
to 28 segments wider than long, the distal segment about the length of 
the two preceding ones taken together. The number of segments is fairly 
constantly 25 on an average (24 to 26), the only exceptions, noticed on 
5 individuals, were: 16/18, 19/26, 23/?— 28/28, 28/? Ocelli regular, 
three in number, disposed in a horizontal row, the posterior ocellus being 
the smallest and the next one the largest. 
Coxae of the maxillipedes as long as broad witli median sulcus very 
distinct, the anterior borders forming a very re-entrant angle, armed 
with 2 + 2 small teeth which are however well formed and sharp. 
All the .shields are laterally marginated, all the posterior corners are 
rectangular or rounded off. 
The two last pairs of limbs are short, very incras.sate without grooves 
or apopliyses in the male. Coxae entirely unarmed.
