to produce natural figures of the insects. A few drops of collodion are al- 
lowed to flow upon the paper until they moisten a apace equal to the wings ; 
these are then laid on and gently pressed down upon the paper. In a few 
minutes the preparation is dry and the wing may be removed, when the 
whole of the scales adhere to the paper. The author remarks upon the dif- 
ferent colours displayed by the two surfaces of some scales, and adds that 
tlie collodion film itself, when detached, furnishes admirable and instmctive 
transparent impressions of the scales. 
T. Goossens publishes a note on the preparation of Caterpillars. lie pro- 
poses to adopt the method of squeezing out tlio contents of the body, inflat- 
ing the empty skin, and drying it by heat, but adds, for those whicli lose 
their colour in this process, the application of the proper tint mixed with 
turpentine, and in some cases a subsequent immersion in melted wax. Ann. 
Soc. Ent. Fr. 4“ s^r. v. pp. 493-496. 
Knaggs has continued his notes on the collecting and management of 
the larvae of Lepidoptera (Ent. M. Mag. ii. pp. 277-278, and iii. pp. 37-41). 
Notes on Lepidoptera frequenting the bloom of the Sallow, by Barrett, 
Ent. M. Mag. ii. pp. 238-239. 
C. G. Barrett suggests a mode of collecting Lepidopterous Insects, espe- 
cially TineidcSj which repose in the chinks of the bark of trees, founded on 
their habit of flying off when disturbed by any movement of the air. Ho 
blows upon the surface of the tree, holding a net in a suitable position, and 
captures the moths as they fly off. Ent. M. Mag. iii. pp. 17-18. 
C. G. Barrett remarks on the moths attracted by gas-lamps. Ent. M. 
Mag. iii. pp. 42-44. 
Barrett remarks upon the capture of Lepidoptera when attracted by 
blackberries. Ent. M. Mag. iii. pp. 113-114. 
Barrett (Ent. M. Mag. ii. p. 2G3) publishes notes on the mode of occur- 
rence of various Lepidoptera collected by him ( Cramhus hamellus and lati~ 
strius, Gelechia diffinis and vdocella^ Oncocera ahcmlla^ Plerophorus paludumy 
Pupithecia irriguatd). Also on Lepidoptera obtained from thatch (1. c, 
pp. 263-264). ' 
A new form of moth-trap, with a lamp, is described by Knaggs, Ent. M. 
Mag. ii. pp. 199-202. 
Rhopalocera. 
Trimen has completed his work on South- Afriean Butterflies 
(Rhopaloeera Africse australis), in whiehhe describes in all 222 
species as inhabiting that region ; but in his interesting summary 
of the geographieal distribution of the species he cites only 220, 
2 of the species of Pierides having been apparently omitted. Of 
these 95 are peculiar to the South-African region, whilst 100 of 
the remainder are known only as inhabitants of Africa, 41 being 
confined to the southern tropical portioii of the continent, and 
59 extending north of the equator. Thus only 25 are common 
to Africa and other parts of the world ; and of these J 6 are re- 
ferred to Africa and Asia alone, and 4 to Africa, Asia, and 
Europe. 
Trimen, in his Notes on the Butterflies of the Mauritius (Ent. 
Trans. 3rd ser. v. pp. 329-344), enumerates 5 species not cited 
1866. [voL. III.] 2 G
