280 . SIR JOHN LUBBOCK ON THYSANURA. 
quatre bandes transversales et plusieurs taches d'un gris foncé un peu rougeätre. 
Téte blanche. Yeux noirs. Poils gris et longs. Sixiéme sega comme dans 
l’espèce précédente. 
* Longueur: 11-3 millimètres. Cette espèce se trouve dans les maisons, où elle vit 
solitaire ; rare.” 
Mr. M°Intire has found this species occasionally in Millbank and Brixton prisons. It 
is, however, as Nicolet says, “rare.” I have never met with it. 
The antennæ are long and slender. 
SEIRA BUSKII, n. s. 
Dark violet, with metallie reflections. Head, legs, and base of antennæ yellowish. 
Eyes on a black patch, and connected by a black band. Spines yellowish at base, 
colourless towards the extremity. 
Length +; of an inch. 
The basal segment is rather shorter than the second or third, which, again, are, though 
very little, shorter than the apical. The hind legs are longest. The feet are all alike. 
There is one tenent hair, not much swollen at the end. The small claw is without teeth. 
The large one has three teeth on the inner, and one on the outer margin. 
I have only found this species in greenhouses and hothouses; perhaps, therefore, it is. 
not an indigenous British species. 
[24th May, Thun.—Since the above paper was sent in to the Society, I have paid a visit to Switzerland 
for the purpose of collecting Nicolet's species, and comparing them with those of England. The Thysa- 
nura would probably have been much more frequent during the autumn months; still I succeeded in 
finding a good many species, on some of which it may be worth while to say a few words*.] 
TEMPLETONIA NITIDA. 
I had already come to the conclusion that Podura nitida of Templeton, one of our 
commonest as well as prettiest English species, was identical with the Degeeria marga- 
ritacea of Nicolet, as well as with the Heterotoma crystallina (= 4theocerus crystallinus) 
of Bourlet. In this view I was confirmed by finding it common in Switzerland. 
ORCHESELLA MELANOCEPHALA. 
Like Nicolet, I found Orchesella melanocephala very common in the woods of Chau- 
mont above Neuchatel. The longitudinal lines, however, in the great majority of speci- 
mens were so much more distinct and striking than in Nicolet's figure, as to give the 
inseet a very different aspect. I should not have called the fourth segment of the 
antennæ “violet” in any of the specimens I found. Lastly, the terminal segment of 
the antennæ was, like the preceding, pale at the base. 
SMYNTHURUS AUREUS, mihi. 
I found this species sparingly. 
* Pauropus I found repeatedly at Grindelwald; and as it has also been discovered in Sweden, there can no longer 
be any doubt that it is an indigenous European species.
