COCCIDAE OF OHIO. 47 
Female: Broadest toward posterior end, segments prominent. 
Median lobes broad at base, tapering sharply and serrate. The mesal 
margins approach at base and apparently fuse, forming a small, club- 
shaped thickening extending anteriorly. Inner lobule of second lobe 
very long and narrow, extending posteriorly two-thirds of length of 
median lobe, and separated from it by almost its own width. Outer 
lobule rudimentary, rounded. Third lobe rudimentary; lobules faintly 
serrate. The gland spines are arranged as follows: 1, 1, 1, 1. 3-4; 
large and conspicuous, decreasing in size toward the median lobes. 
Spines on the dorsal surface are arranged as follows: first on base of 
median lobe, lateral of center; second at base of second lobe, between 
the lobules; third at base of third lobe; fourth about two-thirds of 
distance to penultimate segment, posterior from the fourth gland-spine. 
On the ventral surface, the spines are shorter and located just laterad 
of the corresponding spine. First and second rows of dorsal pores are 
absent; third row represented by 3-5 in the anterior and 3-6 in the 
posterior group; fourth row by 2-4 in the anterior and 5-7 in the 
posterior group. Median group of circumgenital gland-orifices, 4-10; 
anterior lateral, 15-21; posterior lateral, 8-14. 
temarks: Abundant on Gleditsia triacanthos  (Honey- 
locust) at Columbus; also found at Newark, Westerville and 
Cedar Point. 
CHIONASPIS LONGILOBA Cooley. 
Ch. longiloba Cooley, Spec. Bull. Mass. Exp. Sta., p. 16 (1899). 
Scale of female: 1.5—2mm. in length, white or dirty-white in 
color; texture moderately strong, not unlike Ch. salicis-nigrae. Ex- 
uviae, light-brown to dull yellow; about .8 mm. long. 
Scale of male: Small, .6—.8 mm. long, oval and without carinae; 
exuvia, delicate light-brown or colorless. 
Female: Median lobes and inner lobule of second lobe long and 
conspicuous. Median lobes obscurely pointed, serrate, slightly diver- 
gent with small chitinous thickenings at inner bases. Inner lobule of 
second and third lobes, serrate, larger than the outer and more pointed 
than in ortholobis. Inner margin of second lobes bear a small narrow 
chitinous process; third lobe very oblique. The gland-spines are 
arranged as follows: 1, 1-2, 1-2, 1-2, 2-8; decreasing rapidly in size 
toward the meson. Spines are arranged on each surface as follows: 
first at outer base of median lobes; second and third at bases of outer 
lobules of second and third lobes respectively; fourth about two-thirds 
of distance to penultimate segment. The ventral spines are in each 
case smaller and shorter, and located just laterad of each correspond- 
ing dorsal spine. Second row of dorsal pores with only the anterior 
group of 3-5; third row with 5-7 in the anterior and 4-5 in the posterior 
group; fourth row with 5-6 in the anterior and 5-7 In the posterior
