Walker has compiled four Yolumos of the f?o-called Catalogues of the 
Orthoptara oi the British Museum — the Jilnttarieo" (bearing 1808 on its 
titlepagc, with supplement thereto), GryUidcr^' Locustiden” and a por- 
tion of the “ Acrydiid<^y Many “ now genera ” and multitudes of new spe- 
cies ” are described therein. The Recorder has simply enumerated these. 
Like all the other ‘‘ Catalogues ” by this author, these bear the same in- 
tensely mechanical stamp, and there is shown no evidence that he has com- 
prehended the affinities of the insects he enumerates or describes, or that he 
conscientiously appreciates the probable results of his labours. It may be 
confidently expected that the justice of these remarks will be borne out by 
the verdict of orthopterists. So far as the Blattarim are concerned, Brunner 
van Wattonwyl, the highest authority on tlie family, has already approved 
them by anticipation. As a compiler the author has probably no equal ; he 
should limit himself to compiling, and not plunge the knowledge of any family 
he undertakes into utter chaos hy describing new genera and species. The 
few critical remarks here and there given are generally worthless, often abso- 
lutely unintelligible, e. g. Blatta picticollis (Suppl. Blatt. p. 141) : — “ This 
species appears to consist of the genera Blatta and Fynlampra,'^ leading one 
to infer that, to counterbalance his often-proved mistakes in having (in 
other orders) separated one species into many ycnct'n, ho has, in tliis in- 
stance, knowingly grouped insects of different genera under tlie same species. 
Wallengren, (Efv. Sv. Ak. 1871, p. 182, records the addition of four 
described species to the Swedish fauna. 
Grader, Verh. z.-b. Wien, 1871, pp. 367-380, enumerates 66 species ob- 
served by him in Syrmia, a marshy district on the north bank of the Danube. 
Of these, 2 are ForJiculaj'ia:, 4 Blattidcej 1 Mantidce^ 6 Gryllidce, 17 Lociistidce, 
and 24 Acrydiidee. He accounts for the paucity of the list by the fact that 
the district is frequently inundated, and aboimds in frogs and fen-frequenting 
birds.

Brunner van Wattenwyl (Verh. z.-b. Wien, 1870, pp. 161-166), in 
the form of a letter to Dr. Gray, passes severe strictures on the Catalogues 
published by the British Museum, with especial reference to Walker’s 
‘ Catalogue of Blattarim,^ An abstracted translation of his remarks appears 
in the R. Z. 1870, pp. 
Blatta maderce. Bold (Tr. North. Durh. iii. p. 377) notes the occurrence 
of multitudes of these insects in the interior of a sofa that had been brought 
from the East Indies.
