INSECT A — ORTHOPTERA .

Besittingen, Zool., Nos. 6, 7, 8, 9. In these numbers, the families Blattce, 
Mantidce, Phasmidce, Acridece, and Locustidce, are completed, and that 
of the Achetidce commenced. The number of species described and 
figured is great, and many of them are new; American and African 
species are also added, and those of Japan are arranged in order, accord- 
ing to their agreement with those of the Netherland’s India. The 
author has paid great attention to the geographical distribution. With 
regard to system, we may remark, that he considers the families named 
as genera, and the newer genera only as sub-divisions and groups ; 
therefore, when he could characterize new ones, he does not name them, 
although they are fully defined. 
The reporter (Arch. 1842, i. p. 244) has described a number of 
species from Van Diemen’s Land, and, at the same time, drawn atten- 
tion to the preponderance of apterous species in that fauna. About- 
one half of them showed neither traces of elytra nor under wings ; a 
fourth had elytra but no under wings, and most of these were only 
stumps ; and only one-fourth of the species was completely winged, and 
capable of flying. 
Forficulid^. — The reporter has described two new species of Forfi- 
cula from Van Diemen’s Land (ibid. p. 246). The one, F. rujiceps, 
without under wings ; the other, F. pacifica, also wanting the elytra. 
BLATTiDiE. — De Haan (1. c. sup.) has described as new, among the 
Blattce of the Netherland’s India, the following ; — Periplaneta zonata, 
Hagenb., Jiavicincta and concinna, Hagenb., from Java ; Epilampra 
macassariensis, from Macassar; Nauphceta hilunata, from Java; JSf. 
circumdata, from Sumatra. De Haan, in his division, has paid atten- 
tion principally to the absence and the proportionate length of the 
wings ; the reporter (Arch. 1842, i. p. 245) has, on the other hand, shown, 
that like most of the Orthoptera, here also winged and wingless spe- 
cies occur in the same genus, as Serville very correctly states. Of the 
new species from Van Diemen’s Land (ibid. p. 247), Periplaneta me- 
lanaria, atrata, and aterrima, are completely destitute of wings and 
elytra, as well as Blatta trivittata, which approximates the Bl. deci- 
piens, Germ. Bl. marcida has wings. 
Sells (Transact. Ent. Soc. Lend. iii. p. 103) has described the egg- 
shells of several Blattce from Jamaica. 
Mantides. — De Haan has described and flgured many new species 
(1. c. s.) : Mantis valida, Hagenb., from Timor and Amboyna ; hasalis 
and jiava, from Java ; timorensis, from Timor and Amboyna ; herbacea, 
from Japan ; novce-guinece, from New Guinea ; trifasciata, from Brazil ; 
hifasciata, from Cuba; heteroptera, Servillei, and tortricoides, from 
Java. Oxypilus (the author divides this as a sub-genus from Mantis, 
because the species are less than 1" in length ; in the Mantis they are 
longer ; there are, however, other characters, especially the number of
