82 PAPEES ON COCCID-a; OE SCALE INSECTS. 



greens. In September of 1908 it was collected on Tsuga sp., at 

 Queens, Long Island, by Mr. F. N. Meyer, where it had apparently 

 become established, and subsequently it was collected in New York 

 by ]\ir. E. P. Felt on Japanese hemlock. In June of 1909 it was col- 

 lected on the fruit and leaves of Podocarpus elata received by the 

 Bureau of Plant Industry from the Botanical Gardens of New South 

 Wales. Mr. Edward M. Ehrhorn, while horticultural commissioner 

 of California, collected it at quarantine on Podocarpus cMnensis and 

 Pinus sp. Mr. Lindinger in a recent paper ^ records it from the Philip- I 

 pine Islands on Podocarpus nageia and AMes veitcTii and Mr. Brick 

 reports it from Japan on Pinus pentapJiylla, P. thunhergi, and Tsuga 

 sieboldi. 



DESCKIPTION. 



Scale of female. — Fresh female scales frequently covered with a 

 white powdery substance, median carina indistinct and frequently 

 not visible, brown to dark brown, reaching a chestnut brown at the 

 anterior end of the scale; first larval exuvia yellow, about three-fourths 

 of it extending beyond the margin; second larval exuvia 1.80 to 2 

 mm. in length and from 0.60 to 0.80 mm. in breadth. When collected 

 onTsuga sp., it usually occurs on the underside of the leaves, although 

 this does not hold true in the case of the specimens on Podocarpus, 



Scale of male. — White, apparently uncarinated, larval exuvia yel- 

 low. Length about 1 mm. Breadth about 0.40 mm. 



Female. — Thin, pygidium slightly brownish, antennse rudimentary, 

 apparently two-jointed, the second joint bearing a spine; width of 

 pygidium 0.187 to 0.255 mm., slightly truncate at tip, median lobes 

 serrated along free edge, oblique forming a distinct notch, second 

 lobes conspicuous in both second larval exuvia and adult, incised, 

 approximately twice as long as broad, six prominent tubular pores 

 on the margin of the pygidium with two very short spines between 

 the median lobes; gland spines simple, long, one laterad of each lobe 

 and one on the margin near the penultimate segment; on the dorsal 

 surface along the lateral margin of the median lobes there are two 

 spines, the posterior being the larger, one on the outer lobule of the 

 second lobe, and two between second lobe and penultimate segment. 

 Anal opening far removed from the tip and twice the width of a 

 median lobe. Paragenitals in five groups, arranged as follows: 

 Median group 3 to 11, anterior laterals 16 to 24, posterior laterals 

 19 to 31.
