needless to add that thorough and early spraying with a poison, 

 such as arsenate of lead, for the control of the codling moth will 

 prevent serious injury by the apple tent caterpillar. 



Resplendent shield bearer (Coptodisca splend orifer- 

 ella Clem.). Oval, whitish or yellowish, flattened objects less 

 than y$ an inch long, may frequently be observed in midsummer, 

 during the winter or in early spring upon the branches and trunks 

 of apple trees. These are the cases of this insect, a species which 

 is widely distributed and occasionally abundant though rarely in- 

 jurious. It was commonly present last August in the orchard of 

 Mr J. P. Van Ness, East Greenbush. The small caterpillars of this 

 insect mine the apple leaves and form an irregular, dark colored 

 blotch upon the foliage. The full-grown caterpillar cuts away the 

 upper and lower walls of its mine, fastens them together to form a 

 secure retreat and then crawls slowly to branch or trunk, the 

 affected leaf having a somewhat characteristic oval hole, both ex- 

 tremities of which are usually pointed. The adult is about three 

 thirty-seconds of an inch long. The head is nearly concealed by a 

 dense tuft of golden scales, while the brown antennae are trimmed 

 with silvery white scales. The latter are also numerous on the 

 thorax and the base of the wings, though here they have a golden re- 

 flection. The distal part of the wing is remarkable for its striking 

 coloration, there being irregular areas covered with golden yellow 

 scales, a transverse band broken near the middle of silvery white 

 scales and margined on either side with dark brown scales. On the 

 posterior margin of the wing and extending nearly to its tip as well 

 as near the apical middle part of the wing there are relatively 

 large areas covered with rich dark brown scales. The posterior 

 margin of the wing and the extremity are fringed with long, pearly 

 gray scales. The hind wings are a rich deep gray margined with a 

 long, yellowish brown fringe. The legs are clothed with silvery 

 and light brown scales. There are two broods yearly, the moths 

 appearing in May and again in July and August. This insect, 

 though small, is preyed upon by a parasite. We have yet to observe 

 a case where this species was sufficiently numerous to cause mate- 

 rial injury and remedial measures are therefore inadvisable. 



Apple leaf miner (Tischeria malifoliella Clem.) . 

 The trumpet-shaped mines of this common apple insect were ex- 

 ceedingly abundant in mid-August in the orchard of Mr J. P. Van 

 Ness of East Greenbush. This insect is common though rarely 

 numerous enough to cause material injury. The owner informs us
