COCCIDAE OF OHIO. 69- 



one nearly half-way to the penultimate segment; the ventral spines are 

 shorter and just laterad of the corresponding dorsal spine. Dorsal 

 pores in three rows; 1st (at first interlobular incision) usually 2; 2nd, 

 about 8; 3rd, about 4 and near the penultimate segment a group of 3-5. 

 Median group of circumgenital gland-orifices — 4; anterior lateral, 

 4 — 9'; posterior lateral, 3 — 7. Accompanying the groups are peculiar 

 chitinous bands or folds of the body-wall. Anal orifice embraced by 

 extended inner margins of the median lobes. Immediately anterior 

 from the median and second lobes, the segment is thicker and 

 darker brown. 



Remarks : Infests grape-vines, having a peculiar habit of 

 arranging themselves in longitudinal rows on the stem of the 

 host. Not common in Ohio, there being only two infested locali- 

 ties reported as yet.

Aspidiotus f sahalis Comst., 2nd Rep. Dep. Corn. Univ., p. 67 (1883). 



ComstockieUa sahalis Ckll. Check. List, p. 335 (1896). 



Scale of female: Approximately circular, snowy white, 1.5 — 2 mm. 

 broad, exuviae covered, prominent. 



Scale of male: Similar to female scale in color, elongated, more 

 convex. 



Female: There are no lobes or plates; the margin of the segment 

 is rather deeply notched. The female has rudimentary antennae of 

 about two joints and is viviparous. Near the edge of the segment are 

 five very long spines and two similar ones on the penultimate segment. 

 Beginning at the meson on the ventral surface are four small spines 

 equidistant extending to the penultimate segment, which itself bears 

 two. There are also four orifices in two rows extending anteriorly 

 near the mesal notch. There are six groups of circumgenital gland- 

 orifices, anterior lateral, 4-6; intermediate, 5-7; posterior lateral, 8-15. 

 The dorsal pores are very small, arranged in six cephalo-caudal lines. 



Male: Yellow, wingless, with short, spindle-shaped antennae. 

 Remarks : This Coccid was placed provisionally in the 

 genus Aspidiotus by Comstock in his Second Cornell Report. 

 Found by the author on Sabal Palmetto in the 0. S. U. Conserva- 

 tory, at Columbus, Ohio.
