Anx. 12. MASKELL GENERA OF COCCIDAE MORRISON. 113 



tioned, with a small one outside of each median lobe, and another 

 small one outside each second lobe; marginal setae, dorsally one 

 above median lobe, one above inner corner of second lobe, one above 

 inner end of beginning of chitinized margin, one just beyond fourtli 

 marginal tubular duct and one beyond ninth tubular duct, ventrally 

 with one beneath the outer edge of the median lobe, one just out- 

 side the second lobe, one just within the third marginal duct, one 

 beneath the fifth duct and one beyond the ninth duct; without in- 

 cisions with thickened edges or paraphyses, but the edges of some 

 of the marginal duct openings more or less thickened, and apparently 

 with faint chitinized thickenings connected with at least the second 

 pair of gland spines ; anal opening elongate ovoid, placed about half 

 way between base and apex of pygidium ; paragenitals in five linear 

 groups, the anterior three more or less confused, median 7-9, anterio- 

 laterals 14r-22, posterio-laterals 14r-19; marginal pores large, fairly 

 long, one opening into a pointed projection between first and second 

 lobes, and seven or eight more, at approximately'- equal intervals, 

 except the last one or two more widely separated, all these opening 

 within the margin and the openings with thickened edges; dorsal 

 pores large, in three rows, the inner with 2-i pores, the intermediate 

 with about five and the outer with about 7-9; without micropores, 

 but with a few small tubular ducts ventrally near the margin ; with a 

 few small setae ventrally. 



Intermediate stage female. — (Cast skin only.) So far as can be 

 determined, differing from the adult only in the smaller size and 

 reduced development of the different structures. 



Larva. — (Cast skin only.) Antennae apparently 4-segmented, the 

 terminal annulate ; posterior apex of body with two small tubercles, 

 a pair of marginal tubular ducts, a pair of lobes and at least three 

 more ducts at intervals. 



Holotype arid P araty pes. —C?ii. No. 24781, U.S.N.M. 



This species has been described from seven specimens as follows : 

 holotype from specimens in the Department of Agriculture Collec- 

 tion received from Maskell directly, paratypes from same collection, 

 from the Cockerell collection now included in the National Collec- 

 tion, and from Maskell's slides, all labeled M. metrosideri Maskell. 

 The holotype and some paratypes of this species are therefore in the 

 National collection of Coccidae, and some paratypes are in tlie 

 Maskell collection. The species was collected on Metrosideros in New 

 Zealand, presumably by Maskell, and in 1890 or 1891. 



The following generic diagnosis has been prepared to include both 

 of the preceding species.
