Meeting of March 22, 1917. Twelve persons present. Vice-director 

 R. C. Williams, Jr., presiding. 



Lepidoptera. Dr. Skinner reported on. and exhibited a collec- 

 tion of moths collected and presented by Mr. Morgan Hebard, which 

 contained over 1800 specimens. Especial attention was called to the 

 excellent condition of the material. The collection was made in the 

 summer of 1916, by the aid of a 30O-watt electric light, on the porch 

 of a cottage at Hot Springs, Virginia. A vote of thanks was given 

 Mr. Hebard for his generous donation, and Dr. Skinner was com- 

 plimented on the perfect preparation of the specimens. 



Orthoptera. Mr. Rehn exhibited a series of ParatcttLv pre- 

 sented to the Academy by Dr. Nabours, illustrating his studies on 

 inheritance of color patterns in the genus. The true breeding forms 

 and simple and multiple hybrids were represented in the splendidly 

 preserved material. Mr. Hebard made some remarks on his col- 

 lecting experiences in Royal Palm Key, Florida. He exhibited 

 some Orthoptera collected and showed some photographs of the habitat 

 of some of the species. He called attention to the difficulty in col- 

 lecting the walking stick Aplopus mayeri on account of its close re- 

 semblance to the branches and twigs of the bush on which it feeds. 

 It was only by looking for them at night, by flash light, that the adults 

 could be located. E. T. CRESSON, JR., Recorder.
