INJURIOUS INSECTS. 85 



As the females are unable to fly, their distribution cannot 

 be very rapid ; and if our fruit-growers will carefully search 

 their trees during the fall, winter and spring, and remove all 

 the clusters of eggs and burn them, they will prevent the 

 depredations which would otherwise occur. 



Some have thought that because the female is wingless, 

 they could be kept in check by the traps or bands of printers' 

 ink around the trunks of the trees ; but these, of course, are 

 no protection whatever, since this species never descends to 

 the ground, but passes all its transformations in the tree. 

 This insect has two broods in a season. The ego's which 

 have remained over winter hatch about the middle of May, 

 and the eggs of the second brood hatch in the latter part of 

 July. If, therefore, the trees be showered with paris green 

 in water about the middle of May, the first brood would 

 be destroyed along with the canker-worms, and there would 

 be few, if any, left for the second brood. 



The Eye-sjpotted Bud-moth. 



This insect [Tmetocera ocellana, S. V.) was first described 

 in 177G, in Europe, its native country, by Schifiermuller, in 

 his catalogue of the Vienna Collection, and was afterwards 

 redescribed as a distinct species under different names by 

 Fabricius, Huebner and others. In 1841, the insect was 

 described for the first time in this country by Dr. Harris, 

 in his report on the " Insects of Massachusetts Injurious to 

 Vegetation," but this author was not able to refer his insect 

 to the European species, and therefore gave it a new name, 

 — the eye-spotted penthina (^Penthina oculana) . In 1860, 

 Dr. Clemens of Easton, Pa., discovered this insect destroy- 

 ing the buds of pear and plum, and failing to recognize that 

 it was already named, he described it anew and gave it still 

 another name. An examination of the types a few years 

 ago, both in this country and in Europe, revealed the fact 

 that this one insect had received no less than fifteen difier- 

 ent names, a fact which it was necessary to learn in order 

 to discover what had already been published about its 

 habits.
