SYNONYMY. 



A few words of explanation are due in regard to the specific name 

 Melittia satyriniformis used in the title head. This name was giYen by 

 Huebner, who described the species in 1825. Three years afterwards 

 Harris redescribed it as JEgeria cucurbits (Xew England Farmer, vol. 

 VII, p. 33). and later Westwood gaYe the name Trochilium ceto. and as 

 Melittia ceto it has for some reason been generally known in literature 

 and collections up to a recent date. For a discussion of the synonymy 

 and a full bibliography, see Mr. William Beutenmuller's paper ( Journ. 

 X. Y. Ent. Soc, vol. V, pp. 34, 35). 



MANNER OF WORK OE LARVA. 



Ordinarily the larYa works in the woody parts of the stem, boring in 

 both directions and appearing to prefer the portion near the roots. 

 When many larvae, however, occur in a single vine in such abundance 

 as to exhaust their food supply, they eat outward toward the bases of 

 the leaf stalks. In one vine that was examined July 23, 1S98, nearly 

 every leaf stalk had been eaten into at the base, but not entirely 

 through except in a few cases. In these instances the larvae, which 

 were nearly all approaching maturity, had worked through the leaf 

 stalk up to the leaf itself. The larvae, practically throughout their 

 entire existence, are perfectly capable of traveling from one vine to 

 another, and in confinement were able to crawl up the sides of glass 

 jars and to suspend themselves by means of their webs. 



From what has already been stated, it is obvious that the younger 

 larva? are more often found within the leaf stalks, and the older larvae 

 within the main stem. While the larvae confine their work to the 

 stalks, injury is hardly noticeable, but as they grow older and penetrate 

 to the main stems near the roots damage becomes more apparent. One 

 day the plant will look thrifty, and unless one examines the stem very 

 closely for the excrement of the larvae, infestation would readily escape 

 notice, but within the short space of a single day all this maybe found 

 changed. The leaves wilt and die down and examination will now 

 show a place where the stem has been cut off so closely from the roots 

 that the drying effect of the sun has completed the work. A light pull 

 at the stem and it will part at this point. 



NUMBER OF GENERATIONS. 



The question of the number of generations produced annually was 

 practically solved by the late Dr. Kellicott in central Ohio, and Mr. 

 J. I). V. Walker on Long Island. The finding of larvae still at work in
