ZOOLOGICAL LITERATURE. 
Packard, in his ^ Guide to the Study of Insects,’ pp. 666, 667, gives a 
most careful elaboration of the characters of this order, and illustrates it by 
many admirably executed woodcuts. He places it immediately after the 
Hemiptera, and views it in the Linnean sense as containing the families 
Gryllidce, Locustarice, Acrydiid(e) Phasmida, MantidcSj lilaitariaf and Forji- 
ctdarice. 
ScuDDER (Proc. Boat. Soc. Nat. Hist. xii. pp. 228-236) criticises the 
various arrangements of the order as adopted by authors from the time of 
Linn6. His own ideas coincide with those of Packard, as noticed above. 
Gerst ACKER (Archiv fiir Naturgesch. xxxv.) continues his catalogue of 
the insects collected at Zanzibar by Von der Decken and Kersten, enumerating 
the Orthoptertty and describing new genera and species, which will be noticed 
in their proper places. 
Sblys-Longchamps (Ann. Soc. Ent. Belg. xi. pp. 23-42) enumerates the 
additions and corrections to the Belgian Orthoptera noticed since his Cata- 
logue published in 1862; seven species are added, and three suppressed, 
leaving the total nnmber at 43. 
Singer (Jahresb. konigl. Lyceum Regensburg, 18^) describes 47 species 
as occurring in the neighbourhood of Regensburg. 
FoRFICULARIiE. 
Packard (‘ Guide,’ p. 677) briefly points out the leading features of this 
family. They are stated to be rare insects in North America, though so 
abundant in Europe.

Blattidaj. 
Saussure (M^anges Orthopterologiques, fascicule) gives 
a revision of the species described by liim in the first fascicule of 
his 'Melanges^ and in tlie ^ Revue de Zoologie^ for 1864, rendered 
necessary in consequence of these papers having been published 
almost simultaneously with Brunner von WattenwyTs ‘Nou- 
veau systeme des Blattaires.^ He adopts Brunner's arrange- 
ment of the family, wdth some further subdivision of genera, 
and describes many new species. The following is a summary 
of the paper ; — 
Ectobiens. 
Ectobia (Westw.) is divided into three subgenora, founded chiefly ondifie- 
rences in the neuration, viz. : — Ectobia, including lapponica, liinu., crieetrum,
