PSYCHE. 



[February, 1902 



earlj larval life, the insect becoming fastened 

 to the leaf by a secretion. The oesophagus 

 keeps up a regular pulsation, reminding one 

 of that of the heart. Wings are developed in 

 the imagoes and thev are locally known by the 

 name of "white flies." 



Mr. S. H. Scudder stated that he had re- 

 cently heard from a correspondent in Cali- 

 fornia that cave-crickets are injurious to 

 mushrooms. 



Mr. Woodworth spoke of the curious flight 

 of butterflies of the genus Coenonympha very 

 abundant in California in the autumn. 



12 April, 1901. The 220th meeting was 

 held at 156 Brattle St., Mr. S. H. Scudder in 

 the chair. Mr. A. P. Morse acted as Secre- 

 tary. 



Mr. Scudder read a letter from Mr. G. H. 



Johnson of Bradford, N. H., announcing the 

 captiu'e of Enodia portlandia at Webster, 

 N. H.; and one from Mr. H. D. Goodale of 

 Surtield, Conn., concerning a malformed 

 Eiivanessa aiitiofa, an example having been 

 bred which entirely lacked the right liind 

 wing. 



Mr. Scudder announced his recognition in 

 the U. S. orthopteran fauna of the genus 

 Miogryllus Sauss., and showed four species 

 from the southern United States. 



Prof. C. W. Woodworth exhibited draw- 

 ings and models illustrating in a striking and 

 ingenious manner the peculiarities in vena- 

 tion and wing-folding of several genera of 

 insects belonging to the Forficulidae, Blatti- 

 dae and Staphylinidae.
