species of Joppa (Hymenoptera) from the Amazons; a dipteron allied to 
Dasypogon, the hymenopterous Abispa australis, and the coleopterous 
Hesthesis ferrugineus, M‘L., from Australia. Mr. Butler said the lepi- 
dopterous genus Dycladia would complete the trio in the first-mentioned 
case. Mr. Waterhouse did not think it possible that the Longicorn could 
be parasitic on the wasp, as was suggested by Mr. Pryer. Mr. Fitch 
thought if there was any community of habitat it would be that the wasp 
nested in the burrows of the Longicorn. 
Several members took part in a discussion upon the various points raised 
by Mr. Pryer’s criticism of Mr. Lewis’ paper.—E. A. Fircu, Hon. See. 
NOTICES OF NEW BOOKS. 
British Oribatide. By Atpertr D. Micuast, F.L.S., F.R.M.S. 
8vo. pp. 336, with 39 plates. London: printed for the 
Ray Society. 1884. 
Ir is fortunate for biologists that there exists such an 
excellent medium for the publication of scientific works on 
Zoology and Botany as the Ray Society; for it is certain that 
were it not for the aid which this Society extends, many im- 
portant works requiring to be expensively illustrated would never 
see the light. The class to which works of this nature appeal is 
confessedly a small one, hence the difficulty which arises in 
finding a publisher willing to undertake the cost of their pro- 
duction. The Ray Society, in such cases, comes to the rescue, 
and, by the aid of the funds annually raised by the subscription 
of its members (an insignificantly small subscription when 
compared with the value of the volumes annually issued), 
secures the publication of treatises which otherwise would never 
appear, and which in many instances must have cost the 
authors years of unrequited labour. 
To this important series another volume, on the British 
Oribatide, has just been contributed by Mr. A. D. Michael. 
The ordinary English name for the Oribatide is “ beetle- 
mites,” but it is an unfortunate one, because it gives many 
people the idea that they are parasitic upon beetles, and that the 
so-called species Acarus coleopterorum of Linnzus is a type of 
a “a
