COCCIDAE OF OHIO. 63 
tinctly two or three notched on outer margin. Third lobe rudimentary 
and raised to a point. A small chitinous process at inner base of 
median lobes; chitinous processes bounding first and second incision, 
the inner the larger. A pair of simple, inconspicuous plates between 
median lobes and one or two bifurcated ones caudad of each incision. 
Spines prominent, borne on the dorsal surface, one by each lobe, one: 
one-third and another two-thirds of distance to penultimate segment. 
On the ventral surface, they are laterad of the corresponding dorsal 
spines. Rows of dorsal pores very noticeable and complete; first row 
of 3-4; second of 18-24; third of 20-22; fourth, in an irregular row, of 
14-18. Five groups of circumgenital gland-orifices; median, 0-5; anter- 
ior lateral, 8-16; posterior lateral, 4-8. Anal orifice small, level with 
third dorsal pore of first row. 
Remarks: This seale which was first described from English 
Walnut (Juglans regiae) by Prof. Comstock in 1880, has been 
found infesting various other trees, including some of our more 
valuable fruit trees, such as peach, apricot, plum, black cherry 
and pear. It has little economic importance in Ohio. 
Aspidiotus lataniae Signoret.

A. lataniae Sign., Ann. Soc. Ent. Fr., (4), ix, p. 124 (1869). 
Scaie of female: Rather elongated, convex, clear-yellow, trans- 
lucid at center, dirty white at margin of large elliptical exuviae. 
Scale of male: Similar to the scale of the female in color, smaller 
and elongated. 
Female: Mesal lobes only present, large, prominent, nearly as 
broad as long, notched on both margins, the inner notch much the 
smaller and nearer the apex. Two large interlobular incisions 
bounded by chitinous processes, the inner the larger, and one very 
small one, bounded by small chitinous processes, laterad of second 
incision. Usually a small chitinous process at inner base of median 
lobes. Two simple plates between median lobes; two incised plates 
caudad of first and second incision and one or more between them. 
Outside of the small third incision, the margin of the segment is 
produced to appear almost like two or three simple plates. On both 
dorsal and ventral surfaces, spines are located as follows: at outer base 
of median lobes, between first and second incision, just outside of 
second incision, and one about one-half of distance to the penultimate 
segment. Four groups of circumgenital gland-orifices; anterior lateral, 
4-6, posterior lateral, 3-4. Second and third rows of dorsal pores of 
8-12 each, rather straight and distinct although interrupted. Anal 
orifice large, rather remote from the margin.
