 — (Dyar, MS.) 



One of the most common and well-known species. The sexes are similar in 

 color and markings, but the female has only three yellow bands on the abdomen, 

 while the male has four. The insect is an importation from Europe, and in the 

 larval stage it is sometimes very injurious to different kinds of currants and 

 gooseberries. The eggs are deposited in the crevices of the bark on the canes 

 and the larva lives in the pith of the same, making long tunnels sometimes 

 several feet in length. The larva hibernates in its tunnel, and the moth emerges 

 during the latter part of May and during June, the year following. The species 

 has the widest range of distribution of all the Sesiidse, and its literature is very 

 extensive.
