REPORT OF THE STATE ENTOMOLOGIST I912 71 



these insects drift with the wind and were probably carried from 

 the seckels to the Kieffers by light breezes which would naturally 

 sweep up the hill. 



A marked restriction, though not on such an extended scale, was 

 likewise observed in an orchard at Coeymans Hollow and also in 

 that of Mr William Albright about two and one-half miles from 

 New Baltimore Station. In the latter instance injury was particu- 

 larly marked in a hollow and extending part way up on a knoll, 

 while those on the knoll and beyond were not seriously affected 

 though the pest was to be found even there in small numbers. 



Description. The fruit growers will recognize this insect most 

 easily by its operations as characterized above, nevertheless, for an 

 accurate determination, especially in the case of outbreaks at a dis- 

 tance from known infested areas, the microscopic characteristics of 

 the adult must be recognized and on this account we reproduce below 

 the excellent original description : 



Female. Length, 1.26 mm ; width of mesothorax, .32 mm; general 

 color, dark brown. Head about as long as broad ; cheeks convexed ; 

 anterior margin broad, acutely angular ; back of head transversely 

 wrinkled, and bearing a few minute spines. Eyes medium, black, 

 with light borders rounded or oval in outline, coarsely faceted, hairy. 

 Ocelli yellow, margined inwardly with reddish brown crescents, 

 widely separated, posterior ones contiguous, with light borders 

 around eyes ; one very long slender spine on each side midway be- 

 tween ocelli. Mouth cone pointed, tipped with black ; maxillary 

 palpi three-segmented. Antennae eight-segmented, approximate, 

 slightly over twice the length of head. Length of segments : 33, 43, 

 55» 5 2 > 35' 5°' 8> I0 - Antennae brown, except segment 3, which is 

 yellow. Spines pale, conspicuous, special sense organs on segments 

 3 and 4. 



Prothorax longer and wider than head ; bears many prominent 

 spines, the one at each anterior angle, and the two at each posterior 

 angle are longest. Color, yellow-brown ; faintly cross-striated. 



Mesothorax approximately as wide as antennae are long ; front 

 angles obtusely rounded; metanotal plate bears four spines close to 

 front edge, middle pair equal in size and prominence to those at the 

 angles of prothorax, the others are small ; pterothorax yellow-brown, 

 transversely wrinkled. 



Wings present, extending slightly beyond abdomen, about twelve 

 times as long as wide, pointed at ends ; surface of wings thickly 

 covered with minute brown spines ; both longitudinal veins and costa 

 of forewings thickly set with quite long, brown-colored spines, 

 placed regularly on costa and hind vein ; costa has from 29 to 33 

 spines, forevein 12 to 15, and hind vein 15 to 16; veins not prom- 

 inent ; costal fringe of forewings about twice as long as costal spines. 



Legs moderately long, scarcely thickened ; femora and all except
