and a marginal pore, this plate being a little larger than the first one. 

 Following the third lobe, when it is present, or a space when it is absent, 

 there are two spines, one above and one below. These are followed by a 

 plate and a distinct marginal pore, and after an interval interrupted by one 

 or two spines, another plate, and following this another interval, terminated 

 by a group of about three plates. 



The spinnerets are in five groups : median, 7-9 ; anterior laterals, 

 17-23 ; posterior laterals, 23-34. 



Described from dead and shrunken specimens. 



Scale of male. — Length, 1.2 mm. ; feebly carinaled, white, with the 

 larval skin almost colourless. 



Described from a single imperfect specimen. 



Male. — Male insect unknown.. 



The specimens were taken by Mr. Alexander Craw, on palm imported 

 from China to San Francisco, Cal., July 11, 1897. 



I take pleasure in naming this insect after Prof. T. D. A. Cockerel!, 

 who has made extensive and valuable contributions to our knowledge of 

 the Coccidffi, and has shown me many kindnesses in my work on this 

 group of insects. 



CJdonaspis aucubce, n. sp. 



Scale of female. — The female scale somewhat resembles that of 

 Chionaspis Lmtneri in outline, being strongly broadened posteriorly and 

 abruptly rounded at the extremity. It is moderately convex, about 3 mm. 

 in length and about 2 mm. in width. The exuviae at the apex of the scale 

 have the first skin very pale yellow, and the second yellowish or brownish. 

 The second skin is covered with a slight secretion. The scale itself is 

 white and very thick and strong. There is a partial ventral scale at the 

 anterior end. 



Female. — As I had only dead and dry specimens of this insect, I 

 made no attempt to describe anything but the pygidium of the female. 

 Median lobes moderate in size, divergent, united at the base, with their 

 inner edges distinctly serrate. Each lobe of the second pair is composed 

 of two rounded lobules, the incision between the two reaching nearly or 

 quite to the base of the lobe. The inner lobule is larger and projects 

 farther posteriorly than the outer, sometimes surpassing the median lobes. 

 The third lobe is simple and sometimes rudimentary. Between the bases 

 of the median lobes is a pair of minute convergent spines. On each side 

 between the median and second lobes are a spine, a plate and a marginal
