R. W. DOANE AND G. F. FERRIS. — NOTES ON SAMOAN COCCIDAE. 



crenate. From the base of each a conspicuous club-shaped thickening extends into 

 the pygidium, and this in turn is surrounded by a rather irregular area which is some- 

 what more heavily chitinized than the remainder of the pygidium. The characters 

 of the margin of the pygidium are as follows : Laterad of the median lobes a gland 

 pore on a slight prominence, followed by a narrow thickening ; a spine on both dorsal 

 and ventral sides ; two broad, tapering gland spines ; two gland pores ; a spine on 

 both dorsal and ventral sides ; a gland spine ; two gland pores ; a spine on both 

 dorsal and ventral sides, the one on the dorsum being nearer the median line than 

 that on the venter ; a gland spine : a gland pore. All the gland pores except the 

 first are somewhat back from the margin.

Circumgenital gland orifices in five groups, in which the cephalic group contains 

 iour or five, the anterior-lateral five or six arranged in a row, and the posterior-lateral 

 four or five in a cluster. Immediately anterior to the two lateral groups is a narrow 

 chitinized strip. 



Vaginal opening about three-fourths the distance between the anal margin and the 

 anal opening. A very narrow, curved, chitinous strip anterior to the anal opening. 



Although this scale superficially resembles Howardia biclavis, Comst., both in its 

 burrowing habit and in the shape of the median lobes, it is at once distinguished from 

 that species by the presence of the circumgenital gland orifices. It is evidently quite 

 close to Lepidosaphes erythrinae, Rutherford, a species recently described from Ceylon, 

 which also has lobes of the same type, but it differs from that species in the absence 

 of plates and spines between the median lobes. 



On trunks of orange trees, near Apia. 



Mr. H. J. Moors, on whose plantation this and several other of the species recorded 

 here were collected, was untiring in his efforts to aid us in our investigations while 

 in Samoa. 



Parlatoria cinerea, Doane and Hadden. Common on orange.
