The author deduces, from his own observations as well as those already 
published by others on this subject, 1, that there are no true mesothoracic or 
metathoracic spiracles j 2, that spiracles and wings are invariably appurten- 
ances of the dorsal arch ; 3, that a wing is an hypertrophied spiracle ; and, 4, 
that the balancers of Diptera are rudimentary wings. He figures magnified 
dissections of the metathorax and 2nd abdominal ring of Dytiscus marginalisy 
a branchial filament of larva of Phryganea Jlavicoimisy a part of the stem of a 
balancer of Asilus crahronifoi'misy and a balancer of Eristalis tenax.

neficial, and other Insects of the Btate of Missouri. Jeffer- 
son City, Missouri : 1871, pp. 175, 73 woodcuts. 
Some of the observations contained in this pamphlet have already appeared 
ii^Am. Ent. & Bot. (from which many of the woodcuts are borrowed), and 
need not be again referred to. It abounds with practical suggestions, and 
generally treats of economic entomology, though some few new spp. (and 
the earlier stages of others) are also described in it.

This commencement of the author’s proposed catalogue of parasitic insects 
treats solely of Hymenopiera ; it is an alphabetical enumeration (reaching 
the genus Ichneumon) of species of various families, with brief references to 
the insects which they destroy.

The Recorder has not seen this work, which, from notice in Bull. Ent. Ital. 
iii. p. Ill, appears to be the report of a quasi-umpire between the opinions of 
Rondani (Gli uccelli e gli insetti dannosi all’ agricoltura) and Calderini (La 
legge sulla caccia e I’opusculo del Prof. Rondani) as to the importance of 
insectivorous birds.
