"Larvae 41G mu long by half as broad; caudal setae IGO mu long; 

 antennae 100 mu long, G-jointed; formula, (1, 2,) (3, 4,) 5, G; 6 longest, 

 3 and 4 shortest, a lew hairs toward tip; marginal spines conspicuous 

 around the head, a prominent one each side of each caudal seta; 

 claws of feet simple, slightly curved inward, accompanied by a few 

 hairs." Original description. 



Prof. Bogue then says that the specimens are variable in 

 size, color and markings, so that he thinks it possible that more 

 than one species may be included in the description. 



Remarks : First found in Ohio by Prof. J. S. Hine, at 

 Georgesville, Franklin Co., on Quercus alba.

Adult femaie: Length, 2 — 2.5 mm., reddish, oval in outline, sur- 

 rounded by an irregular mass of white wooly secretion, forming a 

 cushion, which at first is in the form of lamellae, but later is more or 

 less fused. The segmentation is fairly distinct and rendered more so 

 by the inward pro.iection of the secretion over each suture. After the 

 birth of the young the female shrivels up and can be easily jarred 

 from the cushion. The antennae are six-jointed, second and third 

 longest, fourth and fifth shortest. The legs are small and slender, the 

 tibia shorter than the tarsus. The ano-genital ring bears eight hairs. 



Adult male: There are two forms of the males; one, the first to 

 emerge from the cottony cocoons, is a form with short wing-pads and 

 a large robust body; the other, the full-fledged males appearing 

 later, are delicate two-winged creatures with large heavy, almost 

 moniliform, 10-jointed antennae. The males are not easily disturbed 

 and seldom take flight. 



Larvae: The young larvae are easily recognized on leaves and 

 twigs, as small oval specks about 0.5 mm. in length, narrowed poster- 

 iorly. Each segment bears laterally a spine, also a ring of six upon 

 the head and a double row on the back. The antennae are six-jointed; 

 joints 1, 2, and 3 the longest. The full-grown male larvae have 7-jointed 

 antennae. 



Remarks: This species which is causing alarm in some 

 eastern states is not common in Ohio; in fact, it was reported 

 only last year, (1902), in Columbus, by Mr. A. F. Burgess, Chief 

 State Nursery Inspector.
