ZOOLOGICAL LITERATURE. 
Marshall (Ent. Mo. Mag. v. pp. 208-234) replies to Dunning on tlie 
gender of Acanthosoma. 
Dunning (1. c. pp. 230, 254) rejoins. 
Dohrn (Stettin, ent. Zeit. 1809, pp. 304-300) addresses a farewell letter 
to Hagen, on the appointment of the latter to the directorship of the Cam- 
bridge Museum, Massachusetts. 
Dohrn (l.c. p. 307), under the heading ‘‘Ouriosum,” ridicules a mistake 
in Griesbach’s Book-Catalogue, wherein certain of his entomological Pre- 
digten” are referred to the section containing theological works. 
Meyer-Dur (Mittheil. schweiz. entom. Gesellsch. iii. pp. 22-28), under 
the heading of Ein Wort tiber die verschiedenen Methoden kleinste Insekten 
in Sammlungen aufzustellen,” discusses the dilferent methods of mounting- 
minute insects for the cabinet. Kriechbaumer (/. c. p. 151) adds a note on 
the same subject. 
Westwood (Proc. Ent. Soc. Bond. 1869, p. iii) describes the method used 
by Green for preparing microscopic objects in Canada-balsam. 
Horne (ibid. p. vi) states that the inner bark of Piniis longifolia is useful 
as a substitute for cork. 
Verrill’s solutions for preserving larvte and other soft forms are referred to 
in Entom. no. 62, p. 219. 
Leconte (Amer. Natural, iii. p. 307), in a short paper on the preservation 
of entomological cabinets, suggests the use of the atomizer ” (vapour-spray 
instrument), with a fluid composed of alcoholic solution of arsenious acid, 
strychnine, carbolic acid, naphtha or benzine, and alcohol. 
Dadant (Amer. Entom. i. p. 99) refers to llaspail’s solution of aloes and 
black pepper, to be mixed with the paste used in lining boxes, as a preservative 
against insects. 
Laboulbene (Ann. Soc. Ent. Fr. 4® s^r. ix. Bull. p. xxii) states that 
specimens prepared with a solution of corrosive sublimate in alcohol are not 
injured by damp. 
Lichtenstein (Ann. Soc. Ent. Fr. 4“ ser. ix. Bull. p. xxviii) points out 
the advantage of using young laurel-shoots both for killing insects and keep- 
ing them flexible j and mentions, on the part of Souverbie {sic), that a sponge 
containing essential oil of bitter almonds has the same effects. Aube objects 
that Cicindela maritima, under the action of laurel, does not keep flexible, 
but turns greasy : Laboulbene also does not believe in the entire efficacy of 
this agent. British entomologists, and especially coleopterists, however, 
have for many years found laurel indispensable. 
Gervais (Ann. Soc. Ent. Fr. 4*^ s(5r. ix. Bull. p. xliv) refers to a solution 
of Quassia amara employed by Cloez for the destruction of insects injurious 
to vegetation. 
Walsh and Riley (Amer. Entom. i. p. 220) describe and figure an ingeni- 
ous contrivance for ridding fruit-trees of insect-pests. It consists of a stout 
frame, running on a single wheel, and from which ribs supporting a canvas 
frame diverge — the whole instrument resembling an enormous inverted 
umbrella, with two handles, like those of a wheelbarrow, and an opening in 
front to allow it, in a measure, to surround the tree-trunk, against which it 
is driven sharply, the insects falling into the frame.
