Ampliidasys cognataria Gtienee. 



Larva a looper, with ten feet ; two inches in length. Head forked, 

 light red. Body with two brown tubercles on the first segment; 

 laterally, on the eighth segment, two transversely-elongate brown 

 warts; on the eleventh segment, two small red warts on a brown 

 patch ; two white dots near the anterior portion of each segment 

 dorsally, and two similar ones below the stigmata of the eleventh 

 segment. 



The larva feeds on maple. Entered the ground for pupation August 

 11th (1859). The imago emerged the latter part of May. 



Abraxas ribearia Fitch. 



Larvse taken on currant bushes, buried in the ground for pupation 

 July 4th. The first imagines appeared ten days thereafter. 



Note on the Season of 1858. 



Pyrameis Atalanta (Linn.) has been rare, last year quite abundant. 

 Pyrameis cardui not observed, but abundant last year. Pieris olera- 

 cea (Harris) has abounded for two years, but, previous to that time, 

 I had been able to collect but a single example. Papilio Turnus 

 has been unusually numerous ; early in the season it was as frequent 

 as Colias Philodice^ while two years previous not one specimen was 

 observed throughout the entire season. Not one Grapta interroga- 

 tionis has been seen, and a very few of Grwpta Gomma or G. Progne. 

 Not a single specimen of Catocala has been collected, while the pre- 

 vious year several species were obtained. 



Note on the Season of 1859. 



A very unfavorable season for collections, in marked contrast with 

 the abundance of insect life the preceding year. Some of the most 

 common Lepidoptera have not appeared at all, and others have only 

 occasionally been seen. The following is a statement of the com- 

 parative abundance or absence of some of our Diurnals : 



Abundant. Few. None. 



Colias Philodice . . . Papilio Turnus Papilio Troilus. 



Papilio Asterias Pieris protodice. 



Pieris oleracea Danais Plexippus Argynnis Myrina. 



Argynnis Aphrodite. . . Argynnis Cybele.
