[September iS??' 



NOTE ON HARRISINA CORACINA. 



Dr. Dyar has described the larva of this 

 insect in Psyche, Nov., 1895. On July 22, 

 1896, I found a batch of the eggs, about 19 

 by 7 mm., on the under side of a leaf of 

 mission grape in Mesilla. The eggs are 

 rather irregularly placed, not touching one 

 another except in a few cases. Shape 

 elongate, about half as long again as broad, 

 parallel-sided, roundedly truncate at ends; 

 resting on one side, not on end; moderately 

 shiny, iridescent, very pale lemon yellow, the 

 surface appearing more or less granular. At 

 that time the imago of H. coracina was 

 flying in numbers in Mesilla, together with 

 a few H. metallica. Both are at least double- 



brooded. On July 26 the larvae had hatched 

 from the eggs ; these young larvae were very 

 pale yellow, without marks; long hairs, some 

 dark, some light; head large, slightly greyish. 

 In 1S97, the first H. coracina was seen on 

 the wing April 24. I have been doubtful 

 whether H. metallica is more than a simor- 

 phic form of coracina. A few days ago, 

 my little son Martin brought me a pair in 

 cop., corac/'«a ? with metallica $. I have 

 eggs from the ? now. Larvae of H. 

 coracina occur here on Virginia creeper as 

 well as grape.
