&c.) by Come, have been communicated to the Entomological Society of 
France by Giraud. In them mention is made of a special work on the 
same subject, which the Eecorder has not yet seen. Bull. Soc. Ent. Fr. 
1807, pp. x^xiii. The locusts visiting Algeria come from the south, and 
arrive in May. They lay their eggs soon after their arrival, and the young 
animals produced from these eggs usually become adult in July. In August 
all usually disappear. Come also notices the arrival in Algeria in the early 
part of January 1867 of a flight of locusts. The colour af these was stated 
to be reddish. It appears that on first attaining tlieir adult form, these in- 
sects are of a rosy tint, and afterwards change ; and Come thinks that it is not 
until after their change of colour that they are fitted for reproduction. 
Lallemant states (/. c. p. xiii) that the Locusts, which live for a long time 
in the adult state, are at first rosy, then emigrate southwards, and return 
in winter of their mature colour.

In this work Walker commences a catalogue of all the de- 
scribed species of Iletcroptera, with indications of those which 
are contained in the collection of the British Museum. In the 
arrangement he has closely followed the system adopted by the 
Recorder in his Catalogue of the Scutata in the British Museum, 
working in the new genera since described, and describing a 
great number of new species. The work promises to be very 
useful, but unfortunately it is disfigured by many misprints.
