;ifi»iiLE JoLY ha 3 published a series of * Contributions pour servir a I’his- 
toire*naturelle des Epb<5m^rines ’ (No. 1, BuU. Ac. Hist. Nat. Toulouse, iv. 
p. 142 et seq.f pi. iii. j Nos. 2 & 3, M^m. Soc. Oherb. xvi. pi. i.), of which 
the Recorder has seen only separate copies, In No. 1 he traces the develop- 
ment of C(£ms grisea, and of what he considers to be a ne\y species, described 
as C, maxima^ from the Garonne, of which he figures the nymph. In 
No. 2 he separates from Palingenia longicauda an insect from Toulouse, de- 
scribed by him under the name P. roaseUj as a new species, but which he 
nevertheless states may be only a variety. Pigures of the nymph accom- 
pany the paper. In No. 8 he records the occurrence in the Garonne at Tou- 
Jouse, in September, of several individuals of the creature first noticed by 
Geotfroy as the “ Binocle a queue en plumet,'* which Latreille subsequently 
placed in his genus Prosopistorna among the Oi'ustacea, He is of opinion 
that it is the larva of an aquatic insect, and belongs to the EphemeridcB^ 
although it has no free external respiratory plates, 
Paling enia virgo, N. Joly, in a paper, Sur Thypermeta- 
imorphose de la Palingenia virgo h Vetat de larve ; analogies de 
cette larve avec les Crustacds,- ^ in Mem, Soc. Toulouse (7) iii. 
pp. 379-386, plate [cf. C. R, Ixxiii. p. 276, and Ann. Sc. Nat. (5) 
XV. art. 10, pp. 1-5], traces the development of this species from 
the egg, and affirms that, at the moment the larya ia hatched, 
it has no visible nervous system, no circulatory apparatus, 
and no special respiratory organs j the antennse and tails have 
a less number of joints than in the more developed larva, He 
considers that it undergoes a hypermetamorphosis, and that 
there is a singular analogy between its development and that of 
certain Crustacea. 
Lucas, Ann. Soc. Ent. Er. (6) i. Bull. p. xliii, gives a specimen of ‘^news- 
paper entomology,” in the form of an extract from the ‘ Paris Journal/ in 
which the sudden appearance of this insect in swarms, termed by the writer 
“ line trombo do papillons,” is referred to the precipitate burials during the 
•disturbances at Paris. 
S. J. Smith, Am. J. Sc. 1871, p. 44, gives a “Notice of a fossil insect’s 
wing from the carboniferous formation of Indiana,” which he names Paolia 
vetusta ; he considers it allied to the EphcmoridcB^ and especially to Ileme- 
ristis and 3Iiamia, stating, however, that Hagen believes it belongs to the 
same genus as Dictyoneura libelluloides, and hence allied to Eugereon hocq-^ 
liingij which Hagen refers to Dictyoneura, 
Odonata. 
Be Selys-Longciiamps, Aper 9 u statistique sur les Odonates,” Tr. E. S. 
1871, pp. 409-410, gives a statistical sketch of the number of species already 
described or known to him. He estimates the total number at 1357 (distri- 
buted in 190 genera or subgenera) as follows: — Libellulines 461, Cor- 
dulines 83, Gomphines 172, 45schnines 108, Galop terygines 160, and 
Agrionines 373.
