NOTES ON SAMOAN COCCIDAE. 



401 



Grouped gland orifices either entirely wanting or present in two groups of but one 

 or two to the group. From each group a very narrow chitinized strip extends 

 posteriorly to meet a rather narrow, slightly chitinized area which extends in from the 

 bases of the median lobes. Dorsal tubular spinnerets rather slender, irregularly 

 scattered over the pygidium but a little more abundant posteriorly. Anal orifice 

 about two-thirds of the way between the margin and the vaginal orifice.

On cocoanut husks at Pango Pango and on an unidentified plant. 

 This species somewhat resembles A. destructor, Sign., but the scale is rather 

 heavier and darker in colour, the body-wall more heavily chitinized, the lobes more 

 distinct, the plates with fewer serrations. The ducts of the dorsal glands on 

 A. destructor are rather long and most of them open on the margin, those of 

 A. faiigoensis are short and most of them open on the dorsal surface. Although 

 we have examined many specimens we find the grouped spinnerets entirely absent 

 or represented by a single gland on each side. 



Chrysomphalus rossi (Mask.). On cocoanut husks at Pango Pango. 



Odonaspis secreta, Ckll. Common on bamboo. 



Lepidosaphes beckii (Newm.). Very common on orange. 



Lepidosaphes gloverii (Pack.). On orange ; apparently much less common than 

 L. beckii. 



Lepidosaphes moor si, sp. n. 



Female scale elongated, widened posteriorly and usually somewhat curved, almost 

 always concealed beneath the epidermis of the bark of the host plant. Colour brown. 

 Length 2 mm. Male scale not identified. 



Adult female elongated, tapering toward the anterior margin, abdomen somewhat 

 constricted between the segments. A single pair of lobes present which resemble 

 very much the lobes of Howardia biclavis, Comst. They are rather triangular in 

 shape, the mesal margin being shortest and the distal margin longest and finely
