592 MR. LUBBOCK ON THE THYSANURA. 



au second segment. Premier segment de I'abdomen brun, avec trois taclies et une 

 bordure post6rieiire jaune fonce. Cinquieme et septieme segmens d'un noir fonc6. 

 Tete tres-noire, ainsi que le premier, la moiti6 inf^rienre du second et le troisieme 

 article des antennes. Les snivants sont bruns et gris. Pattes brunes a la cnisse, 

 grises a la jambe et annulees de jaune. Queue d'un brun 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 O. cmcta. I am also 

 very much disposed to regard O.filicornis as a pale variety of the same species: I 

 have found almost aU of the intermediate links. 

 It occurs with the preceding. 



Orchesella rueescens, 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 sHghtly 

 outwards over the four following segments, dying away at the thu'd 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. 



OuCHESELLA PILOSA, U.S. (PI. LIX. figs. 5, 6, 7.) Ycllowish grey, sometimes with a 

 tinge of green; the body mottled, and the legs annulated with brown or black. 

 Basal segment of the antennte 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 antennse is altogether different. Nicolet also describes his species as having 

 scales, which are " incolores, irregulieres et strides."
