above gnd below. Length about i mm.; width about .75 inch. 

 Laid June i8th; emerged June 28th. 



Young Larva. — Dirty grayish white and covered with rather 

 long hairs of the same color; head also grayish white with a 

 brown spot on each side of the anterior part; mouth parts pitchy 

 black. The head is sometimes entirely black or brown, shining; 

 underside of body same color as above: Length 50 mm. 



Not knowing the food-plant I was unable to rear the larvae to 

 maturity. The eggs I obtained from a number of females flying 

 amongst a species of grass on the border of a well-shaded and 

 dry piece of woods on Long Island, N. Y. ; about fifty imagos 

 were taken. The young larvae, however, refused to eat the grass 

 on which I found the moths, and which I supposed was also the 

 food of the species. 



Apatela innotata Guen. 



Larva. — Head, posterior portion pitchy-brown, anterior part 

 dirty-white, with the mandibles pitchy. Body above dull grayish 

 brown, with a series of four shining, black, piliferous spots on 

 each segment along the dorsal region from the second to the last 

 segment and two rows of yellow spots along each side with 

 another row of black spots between; underside dull grayish. 

 Legs and feet concolorous. The body is also sparsely covered 

 with sordid white hairs. Length 25 mm. Food-plant unknown. 



Found ready to pupate on the trunk of a hickory tree, the 

 bark of which the larva mimics. Collected at Englewood, N. J., 

 Aug. 21, 1890. Imago emerged May 6, 1891. The larva spun 

 a rude cocoon made of small bits of wood.

On looking over the present volume of News I noticed the 

 article in the February number entitled, " Lepidoptera at the 

 Electric Lights," by Dr. Ottolengui. Reading it caused all the 

 difficulties in the way of many of us becoming advanced ento- 

 mologists to rise before me. I handed the book to a young friend 

 of mine and told him to read the article; he has collected about 

 a year, and was greatly interested in the subject. After he had
