ago I now hear from midday until sunset, when most species 

 again become practically silent. If the afternoon is warm and 

 sunny, however, the fields and pastures are filled with various 

 insect sounds. By the roadsides, in the fields among golden 

 rods and asters, the happy musicians disport themselves. Am- 

 blycorypha rotundifolia, Conocephalics cnsiger, Orchelimum 

 ndgare, Scudderia tc.vcnsis, Scudderia furcata, all are as 

 noisy as they can make themselves. It is a simple matter now 

 to observe and capture almost any musician, for all seem less 

 inclined to fly after experiencing the cold nights of this season. 



If the weather moderates suddenly and the evenings become 

 warm with threatening thunderstorms, the usual nocturnal 

 awakening follows. Oecanthus nivcus suddenly starts the 

 warm night air into an almost audible pulsation; the big Cyr- 

 tophyllus perspicillatus rasps out a faster tune ; Conocephalus 

 cnsiger, Ainblycorypha rotundifolia and Scudderia furcata lisp 

 their loudest each in his own manner, until it seems as if the 

 silent shrubs of a few nights ago had transformed their leaves 

 into living, lisping creatures." 



Although the stridulations of insects become noticeably 

 slower and fainter in cold weather, the pitch and manner of 

 delivery characteristic of each species does not materially 

 change. 



MR. J. CHESTER BRADLEY, Special Assistant Entomologist of the 

 Georgia State Board of Entomology, Atlanta, Georgia, has undertaken 

 the preparation of a preliminary catalog of insects of that State, and 

 will appreciate greatly any co-operation on the part of those possessing 

 r.ecords of Georgia specimens. 



DR. F. D. GODMAN has acknowledged the receipt, in London, of the 

 first and principal set of his own Mexican and Central American 

 Odonata, described and enumerated in the Blologia Ccntrali Ameri- 

 cana, from Dr. P. P. Calvert. The specimens will be placed in the 

 British Museum of Natural History. 



MR. R. J. TILYARD'S recently published "Monograph of the genus 

 Synthemis" (Proc. Linn. Soc. New South Wales, 1910, Vol. XXXV, 

 pp. 312-377, 6 plates, 2 of them colored) contains some observations 

 on Corduline dragonflies and their affinities, of interest to students 

 of this group in all parts of the world.
