dopteres. Ann. Soc. Ent. Belg. tome viii. pp. 279-280. 
the author and M. Lambotte have detected a trachea tra- 
versing the centre of the antennse of Anaitis plagiaria. This 
trachea gives off a lateral canal in each joint, leading to an ostium j 
in the same way that the principal tracheje communicate by a 
canal with the stigmata in the body of a caterpillar.

I'he author gives a series of Results obtained by six days^ ob- 
servation, from the 7th to the 12th October 1864, on combs con- 
taining larvae of Galleria. The temperature of the coinbs 
showed an excess of froni 12° to 27°-4 C. (=from 63°*6 to 81°*3 F.) 
over that of the surrounding air.

This paper contains an analysis of the previous information 
extant on the skidulation of C. pudica j find gives a full descrip- 
tion of the anatomical structure of the singular vesicular thoracic 
organ, by the pressure of the hind legs upon which the d,uthor 
believes the sound to be produced. The insect and its vesicle 
are represented in ph lo. figs. 4 & 4 a. Laboulbene gives a list 
of 22 allied species examined by him, in 20 of which the thorax . 
presents no peculiarity, whilst 2 of them {Chelonia matronula and 
C. flavia) show a denuded membranous space on the metathorax. 
The author also describes the similar vesicular organs occurring 
in the genus Setiria, and figures S. aurita with its vesicle (pi. 10. 
figs. 5 & 5 «) . He recommends the formation of a separate genus 
for Chelonia pudica. 
General Notes on the Order. 
Grote publishes (Proc. Ent. Soc. Phil. vol. iv. pp. 318-320) 
some notes on the geographical distribution of Lepidoptera in 
various parts of the United States, especially the Colorado Ter- 
ritory and the vicinity of Chicago. In the former Zygeenidce are 
said to be tolerably numerous ; the Bombycid<s and Bphingidce 
are but poorly represented.
