female cricket, and the spermatophore. The curious method 

 of fertilization was described. 



Mr, Laurent said the larvae of Hemileuca mala (Lep.), when 

 full grown, are from 2^4 to 2^ inches in length. The larvae 

 he reared emerged as imagos in October.

Meeting of December 12, 191 4. Mr. Philip Laurent, Di- 

 rector, presided ; eight persons present. 



Mr. E. T. Cresson, Jr., spoke of the methods of separating

 post-vertical bristles was found to be of absolute value to sep- 

 arate two genera. 



The following persons were elected to serve as officers for

Dr. Calvert described the differences in the dimorphic 

 females of Ischnura verticalis Say (Odon.). (See February 

 News, pp. 56-68.) 



Mr. Rehn made a few remarks on the species of the Orthop- 

 terous genus Atlanticus, all the forms of which were exhib- 

 ited. An intensive study being made by the speaker and Mr. 

 Hebard has brought out the fact that but a portion of the 

 species were properly differentiated in the past. The im- 

 portant features found to be diagnostic of the species were 

 discussed. 



Mr. Williams said he had made some genitalic mounts of 

 genera allied to Lycaena (Lep.) and considered the aedoeagus 

 often showed good generic characters. He said some of the 

 gfenera based on color, maculation and other slight differences 

 were not valid. 



H. Skinner, Recorder.
