592 MR. LUBBOCK ON THE THYSANURA. 
au second segment. Premier segment de 1' abdomen bran, avec trois tacbes et nne 
bordure posterieure jaune fonce. Cinquieme et septieme segmens d'nn noir fonce\ 
Tete tres-noire, ainsi que le premier, la moitie" inferieure du second et le troisieme 
article des antennes. Les suivants sont brans et gris. Pattes branes a la cuisse, 
grises a la jambe et annulees de jaune. Queue d'un bran pale." 
In my specimens, the fourth segment of the body was greenish, and darkened gra- 
dually in front. The thoracic markings were less distinct : the patches were yellowish ; the 
anterior pair, however, with white hairs. The first abdominal segment is but obscurely 
marked with yellow, and the yellow band along the back is scarcely perceptible. 
My specimens, therefore, do not exactly agree with Nicolet's description, and are, 
indeed, in several respects intermediate between the O.fastuosa of Templeton and O. cincta 
of Nicolet. The white patch on each side of the sixth segment of the body, which, 
though sometimes very faint, was always recognizable, induces me to identify them with 
O. fastuosa ; but I should be by no means surprised should that species eventually be 
considered as being merely a variety, perhaps geographical, of 0. cincta. I am also 
very much disposed to regard O.filicomis as a pale variety of the same species : I 
have found almost all of the intermediate links. 
It occurs with the preceding. 
Orchesella rtjfescens, Linn. 
The markings of my specimens of this pretty species do not exactly agree with those 
described by Bourlet. My specimens were yellowish, with reddish-brown markings. 
The principal one was a brown band, which began at the anterior end of the meso- 
thorax on each side, not far from the middle line, and passed backwards and slightly 
outwards over the four following segments, dying away at the third abdominal ; the 
fourth and fifth abdominal segments are somewhat darker than the others. 
The first, third, fourth, and basal half of the second antennary segments are light 
reddish brown ; the rest of the antenna is paler. Eyes black. 
The body is rather narrow, and much less hairy than in the other English species. 
I only found three or four specimens of this pretty species. They occurred with the 
preceding, in spring. 
Orchesella pilosa, n. s. (PI. LIX. figs. 5, 6, 7.) Yellowish grey, sometimes with a 
tinge of green; the body mottled, and the legs annulated with brown or black. 
Basal segment of the antennae pale ; second, third, and fourth brown or black, 
but generally pale at the two extremities ; the two terminal segments pale, tinged 
with brown. Eyes on a black patch. Head and thorax with numerous clubbed 
hairs ; abdomen more sparingly covered. No scales. 
Length \th. of an inch. 
Common in Kent, throughout the year, under logs of wood. 
I at first supposed that this species was the O. villosa. (Nicolet) ; but the coloring of 
the legs and antennae is altogether different. Nicolet also describes his species as having 
scales, which are " incolores, irre^ulieres et striees."
