my c?. If, in the future, the specimen here described should prove distinct, it may be 

 called auricincfa, by which MS. name it has been ticketed in my cabinet. Tlie fact 

 mentioned by Macquart that, though found more particularly in Brazil, Belvosia bifas- 

 ciata has been received from riiiladelphia, and bred from Citheronia regalis, would 

 strongly indicate that we have to do liere with the same species, and that the dilferences 

 just noticed are either defects in the drawing or variations. In the captured specimen 

 in my possession the characteristic golden bauds have become eflTaced by greasing. 



Finally, the same little friendly Ichneumon-fly, {Limneria fugi- 

 iiva^ Say, Rep, 4, p. 41), which was already known to breed in a closely 

 allied congener, {Dryocinnpa stigma^ Sm.), has been bred from it by 

 my lady correspondent, Mrs. Mary Treat, who has forwarded me speci- 

 mens. The larva of this parasite forms its own cocoon within the dis- 

 emboweled skin of its victim, which it kills almost alwaj'^sin the third 

 stage. 



REMEDIES. 



This insect is seldom so exceedingly abundant two years in succes- 

 sion. In 1867 it stripped the soft maples around Peoria, Galesburg^ 

 Princeton and Monmouth, in Illinois, but attracted no particular atten- 

 tion the following year. The worms hold on to the tree tenaciously, 

 and are not easily jarred down ; and, before entering the ground, they 

 scatter great distances away from the trees, so that it is impracticable 

 to hunt for and destroy them while in the chrysalis state. The best 

 way to counteract their injuries is to keep a close watch for the moths 

 and eggs during the latter part of May, when they may be destroyed 

 in great numbers. The worms, when about to leave the trees, may 

 also be entrapped, by digging a trench either around the individual 

 tree or around a grove or belt. The trench should be at least a foot 

 deep, with the outer wall slanting under. Great numbers of worms 

 will collect in it, or bury themselves in its bottom, and may easily be 

 killed.
