REMEDIES AGAINST TEKAS OXYCOCCANA. 25 



or* the Anehyloper a in habit and general appearance'; the head and neck, 

 however, are honey-yellow instead of black; tin- body is of a somewhat 

 paler green, and the larva when full-grown is larger — nearly half an 

 inch in length. The head is nearly as wide as the first segment : and the 

 body tapers gradually to the tail, and is furnished with fine, sparse, pale 

 hairs arising from prominent tubercles; the four dorsal tubercles are 

 arranged in a trapezoid with a deep crease between the anterior and 

 posterior pair ; the anterior three pairs of feet are tipped with black. On 

 each side of the base of the head is a lateral, S-shaped, blackish-brown, 

 linear band, the upper part of the S termiuating on the top of the occi- 

 put, the line being most distinct on the side of the head. The ocelli are 

 black. The pupa is brown, rather slender, and has the head prolonged 

 into a large tubercle surmounted by a large, round and roughened knob ; 

 there is an angular projection on each side of the head, forming a shoulder 

 to it. "The wing-covers reach to the end of the third abdominal ring, 

 while the antennas reach to the end of the second pair of feet, which are 

 parallel to the end of the second abdominal ring. There are two rows of 

 teeth on the upper side of the abdominal rings: they are obsolete beneath, 

 the posterior row being indicated by two remote, minute tubercles." It is 

 about two-fifths of an inch long. There is no appreciable difference in size 

 between the larva of the gray or winter form and that of the summer 

 form, but the pupa of the latter is rather smaller. 



ENEMIES. 



Unlike the Anchi/lopera, which appears free from insect enemies, this 

 insect is preyed upon by two parasites: a dipterous larva belonging to 

 a species of Tachinid aid the larva of an Ichneumouid.* 



These parasites I have found in the second brood only: all my larvae 

 of the first and third broods completed their changes, while those of the 

 second brood were almost all infested with parasites, and these I appre- 

 hend will do much to prevent this species from becoming as plentiful as 

 the Anchylopera. 



REMEDIES. * 



A bog that can be completely flowed need never sutler much from this 

 insect. All that N oeces ary is to keep the water on in the spring until 

 after .May 1. 1>\ that time the surviving moths will either have per- 

 ished without depositing eggs ;it all. or they will h« compelled to de- 

 posit them on the apple trees or whortleberry bushes; the latter being 

 probably their original food before the abundance of cranberries enticed 

 them to the bogs and led to their rapid increase. This remedy has
