■cataivhiense). Both males and females are early enclosed in a 

 white, dense, felt-like, ovoid sac about 3 mm. long and 1.5 mm. 

 wide. The females when removed from the sac are dark purple, 

 have 6-jointed antennae and an anal ring with eight hairs. The 

 dorsal surface is covered with numerous spines and tubercles.

The adult female is concealed by an irregular cottony mass 6 — 

 8 mm. in diameter, on the underside of leaves of hard maple, appearing 

 not unlike the ovisac of a Pulvinaria. The female itself is about 5 mm. 

 in length, oval, yellow and plump; the segmentation showing plainly 

 toward the posterior end. The body surface is covered with spinner- 

 ets which are more numerous posteriorly; also groups of spines are 

 found on the margin of the body. The widely separated, 9-jointed 

 antennae bear numerous, long, flexible hairs. Formula: 9, (1, 2, 3, 5,) 

 (4, G,) (7, 8). Mr. King says in his description that later in the fall 

 when the females are well-filled with eggs, they bear 8-jointed antennae, 

 with the following formula: 4, (8, 2,) 3, (1, 5, 6,) 7. 



The adult male issues from a white, closely woven, oval cocoon, 

 usually attached under the rough loose bark of the trunk and larger 

 limbs. Two long waxy filaments issue from the eighth and ninth 

 segments. Antennae lO-jointed almost as long as the red body. Wings 

 large, covered with white powder and iridescent in sunlight. 



Eemarks : The anthor has found this species on Acer 

 saccliarmn at Columbus, associated with Aspidiotus comstocki 

 Johns.

Female: (adult), 2 to 21/2 mm. in length, 1 to 1% mm. in breadth, 

 flesh-colored and covered with a slight, white powdery secretion. There 

 are seventeen very short, inconspicuous, lateral filaments on each side. 

 Although the filaments are short, spinnerets and numerous hairs are 

 scattered over the surface of the body, being especially numerous in 

 the cephalc region. On the anterior ventral margins of the second and 

 third segment, are two large spiracles. The anal lobes, bear each, 

 two long hairs and three short ones, besides the spines. The large, 

 retracted anal ring bears the customary six long hairs, and is con- 

 spicuously dotted. The eyes are prominent, though not large. The 

 antennae are nine-jointed. The formula is as follows: (3, 2,) (4, 9, 5,) 

 1, 8, (6, 7). The legs are well developed and darker in color than the
