hibited the illustrations charts showing these proportions of which 

 the Diptera represented nearly one-half of the total. He also re- 

 marked on his own experience along this line. Mr. Baylis said that 

 he had caught a dragonfly in the act of devouring a Vespa maculata. 



Meeting of March 23, 1916. Seven persons present, Mr. Morgan 

 Hebard presiding. Mr. William S. Huntington was elected a member. 



Hymenoptera Mr. G. M. Greene exhibited a specimen of Atta 

 ccphalotcs, collected Aug. 9, 1911, at Chaco, Argentine Republic. Dr. 

 J. C. Bradley exhibited some Mutillidae, calling attention to some 

 structural characters which he discovered to be very constant and 

 much more satisfactory than the color characters. In working out 

 these characters he found that there are several distinct forms con- 

 tained within the limits of some of the present species as based upon 

 the color characters. 



Orthoptera. Mr. Rehn exhibited a box of striking species of 

 tropical American Tettigoniidae and Mantidae chiefly from Costa 

 Rica. Three of the species shown are undescribed and two of the 

 genera have not been recorded from Central America. He made a 

 few remarks on the specimens shown. 



Mr. Hebard spoke of the high prices asked by foreign dealers for 

 such striking insects, while the more inconspicuous specimens, even 

 if they are types, may be purchased at a proportionately much lower 

 price. E. T. CRESSON, JR., Recorder. 



American Entomological Society. 



Meeting of February 24, 1916, at the Academy of Natural Sciences 

 of Philadelphia, Dr. Henry Skinner, President, in the chair. Ten mem- 

 bers present. Dr. Witmer Stone was elected a member. 



Lepidoptera. Dr. Calvert reported the presence of fragments of 

 insects on the silk larval cases of a lepidopterous insect in bag worms 

 from Costa Rica (see also below). He also reported having seen 

 sleeping clusters of Heliconins charitonius there. Dr. Skinner exhibit- 

 ed a photograph of some of the types of the American species of the 

 genus 1'arnassius. 



Coleoptera. Dr. Skinner exhibited a specimen of Alcgasoma ele- 

 phas 9 and also a live $ ; both were brought in alive by an officer of 

 the United Fruit Co. ; they were fed on bananas ; attention was called 

 to the great strength of this insect as exhibited by the living example. 



Hymenoptera. Prof. Bradley reported that in 1907, in an arid dis- 

 trict in California, he found Hymenoptera sleeping in clusters, there 

 being five species so found; they attach themselves by their mandibles, 

 their bodies and hind legs being extended. 



Orthoptera. Mr. Rehn made a few remarks on asymmetry in the
