sexes hopped freely when disturbed, the males invariably 

 ran after the females, and the latter only tried to escape 

 by running. In the case of StetJtophi/ma fuscum the rivalry in 

 stridulation between the males was very apparent. Two 

 males were found fighting, and even then stridulation was 

 part of the contest, and always seemed to produce a very 

 irritating effect on the antagonist. In another case a 

 male was seen attempting to pair with a female which 

 was already paired, and in this case too stridulation played 

 an important part in the advances made by the former. 

 Stridulation was the chief or perhaps the only method of 

 courtship in two species of StenobotJinix. In PsopJnis stmhdus 

 a rattling sound was made by the males during flight (pro- 

 bably by the wings), but they also made a curious kind of 

 twitter with their legs when in the presence of the females. 

 Prof. Poulton said that some slight observations upon CEdipada 

 (probably (E. candeftrenx) were made at Fribourg, but far more 

 investigation was needed before it is possible to come to a 

 conclusion as to the habits of this species during courtship. 

 The habits recorded in the paper were greatly influenced by 

 temperature, and it was found that certain phases of court- 

 ship could be most satisfactorily studied when the insects 

 were first roused into activity by the morning sun. Prof. 

 Poulton further stated that it was probable that the pairing 

 time was nearly over in the case of some of the species under 

 observation, and this would explain the great difference 

 between re:oti'tti.v and Gomphocerm in this respect. The 

 localities where the observations were chiefly made, and the 

 appearance of the three first named species, were illustrated 

 by lantern slides projected upon the screen. 



Prof. Meldola expressed great interest in the paper, and 

 said that the observation of the habits of insects in the 

 field seemed to be much neglected by many Entomologists. 

 Dr. Sharp remarked that there was a greater variety in 

 'the organs capable of producing sound in the Orthoptera 

 than was generally supposed,
