Mr. Davis exhibited Tricrania sangiiinipennis found dead on April 22 at 

 Watchogue, Staten Island, and commented on its distribution and habits ; 

 also Danais archippus found on the sidewalk at St. George, Staten Island, 

 April 25 and flying in Brooklyn April 29, these dates being early for an 

 insect known to migrate in the fall. 



He also exhibited Alypia octomaculata found on April 28, saying that it 

 was also unusual so early in the year, though common on grape vines in June 

 and July. The subject of its being double brooded was discussed by him and 

 Messrs. Olsen and Watson and, after the meeting closed, reference was made 

 to Dr. Riley's article in Am. Ent., II, 1870, p. 151. 



Dr. Bequaert, after recalling his remarks at a previous meeting on the 

 color varieties of Eumenes, showed from the specimens of African wasps 

 previously exhibited, analogous variations in the great series of Synagris 

 cornuta, as well as equally remarkable variations in the size of the jaw-like 

 horns, which, however, always preserved their characteristic color. He said 

 he was unable to trace any correlation between these variations and climatic 

 or other conditions or to associate them in any way with protective coloration.
