336 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



laterals consist of from seveu to sixteen, and the posterior laterals of from four to 

 eight. 



There are two or three pairs of lobes. The median lobes are well developed, but 

 vary in oiitliue ; the second lobe of each side is less than one-half as large as the 

 median lobes, elongated, and with one or two notches on the lateral margin ; the 

 third lobe is still smaller and pointed, or is obsolete. 



There are two pairs of incisions of the margin, one between the first and second 

 lobes of each side, and one between the second and third lobes ; they are small, but 

 are rendered conspicuous by the thiciienings of the body wall bounding them. 



The jilates are simple, inconspicuous, and resemble the spines in form. The larger 

 ones are situated one caudad of each incision. 



The spines are prominent, especially those laterad of the second and third lobes ; 

 the fourth spines are a little nearer the first lobes than the penultimate segment, and 

 the fifth are near the penultimate segment ; there is also a spine at or near the union 

 of the last two segments. 



Scale of male. — The scale of the male resembles that of the female in color ; it is 

 elongated, with the larval skin near the anterior end ; this skin is covered by excre- 

 tion, but its position is marked by a rose-colored prominence, as in the scale of the 

 female; the anterior part of the scale is much more convex than the posterior pro- 

 longation, which is flattened. There is a rudimentary ventral scale in the form of 

 two narrow longitudinal plates, one on each side of the lower surface of the scale. 

 Length, 1.25>"'" (.05 inch). 



Habitat. — On the bark of the larger limbs of English walnut (Jiiglans regia), at 

 Los Angeles, Cal. Described from sixty -three females ; and manj' scales of each sex. 



There are in the collection of the department specimens of Asjndiotns from locust, 

 pear and cherry, from New York and District of Columbia, which apparently belong 

 to this species. (Comstock.)
