MR. LUBBOCK ON THE THYSANURA. 
595 
This species most nearly approaches the D. platcmi of Nicolet, but may be at once distin 
guished by the colour of the first abdominal segment, which in the latter species is pale. 
It has no scales. Each leg has a tenent hair ; and the large claw is provided with twc 
teeth. It occurs on the bark of trees, and under logs of wood. 
Length -^th of an inch. 
Pound during spring and summer, in Kent and Lancashire. 
Degeeria Platani, Nicolet. M. Nicolet's description of this species is as follows : 
" Corps 6cailleux, a reflet argents, un peu plus fusiforme que celui du precedent, h 
tete plus petite et plus allongee, ayant les angles posterieurs arrondis. Poils noirs. 
Tete et premier segment thoracique d'un jaune-orange assez fonc6, et hordes an- 
teneurement de noir : second segment noir. Premier segment abdominal d'un jaune- 
orange-pale ; les deux suivants noirs, et separ£s par une ligne transversale tres-fine 
du meme jaune et bordant le segment anteneur. Le quatrieme segment, egale- 
ment orange-pale, porte une large tache irr^guliere noire sur son milieu, et une ligne 
transversale de meme couleur a son bord posterieur. Anus et bord poster ieur d< 
l'antepenultieme segment £galement noirs. Antennes, pattes, dessous du corps et 
queue d'un jaune-pale tres-leger, les premieres un peu plus foncecs et ai melees de 
noir ou de gris ; souvent un anneau noir k l'extremite" des cuisses postericures. 
" Longueur environ 2 millimetres. Se trouve sous les ecorces du Platauus oriental™ ; 
jez commun en ete ; vit solitaire." 
I found my specimens in June, on the bark of beech, in company with Psocus, &c. 
Templetonia, n. g. 
Body long, cylindrical, provided with clubbed hairs like those of Degeeria and Or- 
chesella, and also with scales. Segments eight in number, subequal. Head direct, 
or nearly so. Antenna longer than the head, five-jointed ; the basal segment short, 
the three following subequal, the apical ringed. Basal part of the saltatory ap- 
pendage more than half as long as the two terminal lamellae. 
This genus is proposed for the reception of Templeton's Podura nitida, which is not 
very rare in Kent. The structure of the antennae is alone sufficient to distinguish it from 
all the other Poduridce. They have five segments, of which the first is quite short, the 
three following are cylindrical and subequal, while the terminal is ringed and shows, 
therefore, some approximation to a character hitherto peculiar to Macrotoma. It differs 
also from Isotoma in the peculiar form of the hairs, in the presence of scales, and m the 
form of the saltatory appendage, while agreeing with it in the general form of the body. 
On the other hand, while agreeing with Degeeria in the tegumentary appendages, it 
differs in the form of the body-segments. At the same time, it is more nearly allied 
to Degeeria and Isotoma than to the other allied genera, though in the position of the 
head it makes some approach to Lepidocyrtus, and in the termination of the antennae 
to Macrotoma. On the whole, therefore, this genus presents us with a most mterestmg 
combination of characters.
