children at so much per pound and the use of turkeys, which 

 ate the insects when shaken from the trees or such as were 

 within their reach on the lower limbs. Some years ago he had 

 all the banana and other trees and shrubbery cut from the 

 coffee fields, hoping that would serve to discourage the pest. 

 Little result seems to have followed. He now r asks very ear- 

 nestly what he shall do. Knowing little of the life or habits of the 

 insect and nothing of the effect of arsenical or other sprays 

 on the coffee tree, Mr. Caudell did not know what to advise. 



Mr. Quaintance suggested that arsenical treatment might 

 be used and Mr. Knab thought sweetened poisoned bait might 

 be of value. 



Mr. Schwarz stated that according to Senor Mejia, these 

 Orthoptera appear at the beginning of the rainy season as 

 unwinged specimens and acquire their wings shortly after. 

 It appeared to Mr. Schwarz that oviposition probably is

 ought to be ascertained, as it has an important bearing on 

 eventual remedial measures, whether the young specimens are 

 found on weeds or on tall trees used universally in these re-

-Mr. Walton said : I wish to announce on behalf of Mr. 

 E. O. G. Kelly, of the Bureau of Entomology, who is now 

 stationed at Wellington, Kansas, that he has apparently 

 settled definitely the old argument as to whether the American 

 members of the genus Sarcophaga are truly parasitic or not. 

 During the past summer there has been a severe outbreak of 

 Melanoplus differ entialissfoA Mclanoplusbivittatus'vn. Kansas, 

 w r hich Mr. Kelly has been studying. 



In the course of his observations he noticed that when the 

 grasshoppers flew through the air certain flies apparently 

 followed them and darted down at them while on the wing. 

 Upon capturing some of the grasshoppers he discovered tiny 

 maggots attached to the abdomen, watched them enter the 

 grasshopper through the tender spaces between segments, and 

 reared the adult flies from them. I have examined the series 

 of adults sent me for determination, and have been able to
