282 THE CANADIAN ENTOMOLOGIST. 



and the variety can be separated are the presence of the median notch 

 in the variety and the larger size and more rounded form of the lobes in 

 pinifolice. 



Scale of male. — The male scale cannot be distinguished from that of 

 pinifolice. It is slightly more than i mm. long and .4 mm. wide at the 

 posterior end, where it attains its greatest width. The scale is white, with 

 a moderately distinct median carina. The larval skin is like the first one 

 of the female. 



Male. — Male insect unknown. 



On Cuban pine, Fifius heterophylla, from Florida. I am indebted 

 to Prof A. L. Quaintance for a bountiful supply of specimens, as well as 

 to Prof Cockerell, who first called my attention to this insect and sent me 

 specimens. 



The scales are found chiefly at the bases of the very long, slender 

 leaves, and mostly on the inner surface. A few specimens occur also on 

 the stems of the new growth. There were circular openings in a few of 

 the female scales, from which parasites had emerged. 



The following original description, which has never been published, 

 was sent to me by Prof Cockerell to be added to this paper : 



Chionaspis latissima, Ckll.

 (Descriptive note; no full description.) 



" Female scale circular, 2 mm. diam., white, semitransi)arent, with the 

 light ocreous exuvife to one side, first skin half overlapping second, 

 second skin oval. Eggs shining, pale pink.

" 9 when boiled in caustic soda turns yellow, marbled and suffused 

 with bright blue-green ; the mouth-parts remain a warm brown. Under 

 pressure the $ becomes greatly elongated. Anal orifice level with the 

 lower (caudad) edge of the cephalolateral glands. Five groups of ventral 

 glands, median of 8, cephalolaterals of 18, caudolaterals of 20. Lateral 

 dorsal rows of elongated pores. General characters o^ c/iinensis,nyssce,t\.c. 

 Differs from chinensis by the median lobes being not or barely brownish, 

 and being decidedly produced, and the second and third lobes each 

 represented by three distinct lobules. The lobes are much more ]:)roduced 

 than in /lysscc. The s]:»iiielike plates are large. The scale is very similar 

 to vitis, Green, but is smaller than that or varicosa, Green.

 found by Mr. Alex. Craw, April, 1897, in the course of his quarantine work 

 at San Francisco.'"
