MR. LUBBOCK ON THE THYSANURA. 
Templetonia nitida (Fodura nitida, Templeton). Templeton's description of this 
species (I.e. p. 94) is as follows : — " Body obovate, smooth, shining ; head globular, 
a little produced anteriorly ; eyes reddish brown. Thoracic and abdominal rings 
pale, with innumerable reddish-brown streaks and spots, especially basally, and two 
or three strong hairs in the middle ; a collar of similar hairs encircling the neck, 
and minute ones over the whole body. Antennae and legs pellucid. 
" Length -09 inch. Common at Cranmore, in the grove." 
This species I have found in Kent, several times during the spring, though never in 
any great numbers. When alive, they were silvery white, so that at first sight they 
might easily be mistaken for specimens of L. argentatus ; when, however, they had been 
for some few days in spirits of wine, the reddish spots mentioned by Templeton made 
their appearance. 
Isotoma. 
Isotoma fuliginosa (Fodura fuliginosa, Templeton). Templeton's description of this 
species is as follows : — " Body subcylindric, greenish black. Head subtriangular. 
Antenna? not much longer than the head ; joints nearly equal. First thoracic ring 
much larger than the succeeding ; third abdominal also very large ; a black line 
down the middle of the back. Legs short, tapering, pale greenish. 
" Length '05 inch. 
" A few specimens at Cranmore, under the bark of a rotten tree." 
My specimens did not exactly agree with this description. Mr. Templeton seems to 
me to have misunderstood the structure of the thorax, as the mesothorax is larger than 
the following segment, and the prothorax is scarcely visible from above. The abdominal 
segments in my specimens were less unequal ; they had bluish lights ; the antennae were 
dark ; and there was no black line down the middle of the back. The length of the head 
was only sooths, while that of the antenna? was i^ths, or nearly double ; but this pro- 
portion does not differ much from that shown in Templeton's figure. The first and third 
segments of the antennae also are rather shorter than the second and fourth. The salta- 
tory appendage was white ; but I hesitate, in spite of these differences, to form a new species, 
looking rather upon my specimens as a dark variety. The feet had sometimes one, some- 
times several, tenent hairs. The caudal fork was short, and did not reach nearly to the 
ventral tube. 
January to April. 
I did not find them very often, but generally in considerable numbers. 
Isotoma Anglicana, n. s. (PL LIX. fig. 8.) Colour purplish greenish brown. Eyes 
on a black patch. Under side of head and thorax the same tint as the back, but 
slightly paler. Anterior abdominal segments browner ; saltatory appendage gra- 
dually passing into white towards the extremities. A few scattered pale spots, and 
one or two pale lines, along the side. Basal segment of the antenna rather shorter 
than the other three, which are nearly equal in length. Body covered with short 
hairs and some longer setae, especially on the thorax and the posterior abdominal 
segments.
