briar and a correspondent reports rinding it in apple branches 

 in West Virginia. Mr. Fiske found it at Tryon, N. C., boring 

 in the pith of hickory twigs, and at New Landing, S. C., 

 abundant in the stems of smilax. It appears that the larva has 

 not been observed, therefore the breeding habits of this species 

 are uncertain. 



Doctor Hopkins showed also specimens of the Cnesinus 

 mentioned in the preceding note, and drawings of structural 

 details of the Cnesinus, the Pagiocerus, and the hickory bark- 

 beetle (Scolytus quadrispinosus Say). 



Mr. Schwarz reported that he found adults and larvae of 

 the cabbage butterfly (Pontia rapes L.) present in hundreds at 

 Trece Aguas, Alta Vera Paz, Guatemala, last spring. This 

 butterfly does not seem to have been recorded from Guatemala 

 and it was an interesting subject for conjecture how it reached 

 this rather inaccessible part of the country. Very little vege 

 table produce comes to Guatemala from the United States, most 

 of it being imported from Germany, and it would seem that the 

 latter country must prove to be the source of the infestation. 

 Mr. Schwarz described the exceedingly mountainous character 

 of the country in Guatemala. 



Mr. Quaintance asked the opinion of the members as to 

 the function of the cornicles or nectaries of the Aphididse. He 

 stated that David Sharp, in the portion of the Cambridge 

 Natural History treating of insects, says that although, it was 

 formerly supposed that the honey dew is excreted from the 

 nectaries it is now known that this is not the case, but that this 

 substance is excreted from the anus. Mr. Quaintance stated 

 that he had himself observed globules exuding from the necta 

 ries of the cabbage aphis (A. brassicce L.), the apple aphis 

 (Aphis mali Fab.), and the red goldenrod aphis (Siphonophora 

 rudbeckice Fitch). Mr. Pergande, too, had informed him that 

 he had often seen globules of liquid exuding from the nectaries 

 of aphides of many species not only from those having exter 

 nal tubes but also from those in which the place of the tubes is 

 taken by two simple openings or pores and in making balsam 

 mounts of aphides from life he had seen drops of fluid exuding
