This peculiar, long, narrow scale was found on oranges in 

 the Columbus markets. It is often associated with the preceeding 

 species.

Scale of female: Long, 2.5 — 3 mm., more or less curved, gradually 

 widened posteriorly, brown or dark-brown, shining, thick in texture, 

 with exuviae yellowish or yellowish-brown. 



Scale of male: Similar in color to scale of female, but smaller. 

 The posterior one-fourth of the scale bends upward like a hinge for 

 the exit of the male. , 



Female: The median lobes are large, broader than long with 

 parallel margins, deeply notched on each side near the apex and 

 rounded; slightly diverging. Lobules of second lobe rounded; the 

 mesal much the larger. Third lobe rudimentary. Plates long, simple; 

 two in each of the folowing places: between median lobes, between 

 flrst and second and between second and third lobes, laterad of third 

 lobe, and one about half-way to penultimate segment. There is an 

 elongated pore laterad of first lobe, two laterad of the third and fourth_ 

 pairs of plates respectively, and one laterad of the fifth pair of plates. 

 The spines on the dorsal surface are longer than the ventral spines 

 and situated as follows: one at base of each margin of flrst lobe, one 

 dorsad of incision of second and third lobes respecitvely, and one 

 between the fourth and fifth pair of plates. On the ventral surface, 

 there is a spine at the base of each margin of the median lobe, third 

 spine at base of outer margin of outer lobule of second lobe, and the- 

 fourth and fifth spines between the fourth and fifth pairs of plates 

 respectively. There are four or five spines on the lateral lobules of 

 the penultimate segment. Second row of dorsal pores, (extending- 

 anteriorly from the third pair of plates) of about 12 small rounded 

 orifices; third row of about 10; fourth row (near margin) of about 6. 

 Median group of circumgenital gland-orifices, 10 — 18; anterior lateral 

 and posterior lateral, 16 — 22 each.
