202 ENTOMOLOGICAL NEWS. [Sept 



carnations in the greenhouse were dying from some unknown 

 cause. I investigated the matter and found no cause except 

 numbers of minute white larvae which were boring inside of all 

 the stems that showed serious injury. 



From these larvae I reared several adults which were easily 

 traced to the genus Seiara, but not being sure of the species I 

 sentspecimens to the Department of Agriculture at Washington 

 where they were labeled inconstant. From what I knew of the 

 habits of the larvae of the Mycetophylidae I supposed at first 

 that the plants were killed in some other way and then were 

 attacked by these insects, but by farther observation I was 

 convinced that they fed upon the growing plants.

LIFE HISTORY OF NOTODONTA GEORGICA-H S 



BY HARBISON (I. DYAK. 



This larva is here described for the first time. Dr. Pack- 

 ard's description (Mon. Notodout., p. 154) of georgica larva 

 was taken from some specimens in the National Museum which 

 appear to have neverjbeen bred. What reason led to theij 

 identification as georgica is unknown to me, but they are in 

 reality evidently larvae of Heterocampa obliqua. 



It will be remembered that Abbott and Smith figure N. 

 georgica and N. anguloxa as sexes of one species. My breeding 

 explains this matter, since the larvae of these species have the 

 same food plant and habits and moreover resemble each other 

 almost to identity. The main difference is the colored tuber- 

 cle on the eighth abdominal segment of georgica. Apparently 

 Abbot, overlooking this slight difference, figured the two spe- 

 cies as sexes of one, since he probably bred them from what 

 he considered the same larva. 



Egg. I have not found these in nature. Eggs from the ab- 

 domen of the female moth are apparently hemispherical, white, 

 coarsely granular rather than reticular and about 1 mm. in 

 diameter.
