spring. The larva is rather prettily marked : and I trans- 

 cribe from my notes made for me in breeding by Miss M. E. 

 Murtfeldt. 'Length 7 mm., slender, somewhat depressed, 

 tapering slightly in both directions trom the middle. Head 

 as broad as segment, rather long, polished black. 1st .seg- 

 ment corneous jet black like the head ; 2nd segment dull 

 velvety black; anterior half of .segment o milk white, pos- 

 terior half velvety purplish black. Abdominal segments 

 dull purple, transversely banded on dorsum with irregularly 

 margined .stripes of pinky white, with two interrupted lateral 

 stripes of same color. \''entral surface purpli.sh brown, legs 

 black, prolegs concolorous with general surface. Anal plate 

 margined with white.' " 



I have given Dr. Riley's description at length in order 

 to compare with my specimens of larva, which do not agree 

 with his specimens pcssibly owing to the diflference in food 

 plant. 



The length of a full grown larva is about 10 mm., slight- 

 ly depressed. Segments 2nd to 10th all of one size, 2.5 mm., 

 across the back, and a little less than 2 mm. in depth. From 

 the lOtli segment the body tapers rapidly to 1 mm. Head 

 smaller and shorter than 1st segment, bi-lobed, ocherous 

 with a darker triangular piece between the lobes; 1st segment 

 lighter in color .shading to white; 2nd, 3rd and abdominal 

 segments pure white, without marks or stripes on either 

 dorsal or ventral surface. Prolegs white; legs, 1st pair dirt}- 

 white, 2nd and 3rd pairs pure white. The Qgg I have so far 

 failed to secure; but think it is laid in the blossom, as I have 

 found the newly hatched larva in the ovary .soon after the 

 blossom has fallen. It eats the pulpy portion of the berry, 

 generally avoiding the seeds, and causing the skin to shrivel. 



The larva .spins a slight silky cocoon and transforms 

 within the berry, making its way out through skin and husk. 

 It surely is only single brooded on the ground cherr)'. It 

 may possibly rear another brood as a leaf folder or leaf 

 miner on some other host plant. Otherwise it must hiber- 

 nate as a moth and live until the fruiting season, which is 

 usually during July and August.
