ART. 12. MASKELL GENERA OF COCCIDAE MORRISON. 89 



these species, no attention has been given to the question of possible 

 specific synonomy. 



The following generic diagnosis has been based largely on the 

 specific description preceding. 



GENERIC DIAGNOSIS OF P0LIASPI3. 



Diaspine forms, probably belonging in the generic group contain- 

 ing Aulacaspis fentagona (Targioni) ; scale of male elongate, Chi- 

 onaspis-like, but without carinae ; scale of female elongate pyrif orm, 

 exuviae terminal; body of adult female membranous, elongate oval, 

 antennae tiny tubercles, spiracles normal, all accompanied by a 

 closely set cluster of pores, margins of thoracic and abdominal seg- 

 ments with small short tubular ducts, gland spines and tiny setae, 

 pygidium rounded, median lobes large, more or less protruding, not 

 contiguous, with an intermediate pair of setae, second and third lobes 

 more or less developed, divided into two lobules where distinct, gland 

 spines present, the posterior ones arranged singly, marginal setae 

 normal, without incisions or chitinous thickenings, anal opening 

 moderate, circular, nearer base than apex of pygidium, paragenitals 

 present, in eight groups, marginal pores present, axis longitudinal, 

 inner single, remainder in pairs, dorsal pores in distinct linear rows, 

 split into two groups, axis longitudinal, pygidium with some indis- 

 tinct thickenings running cephalad from margin, with ventral mi- 

 cropores and both dorsal and ventral setae; intermediate female in 

 general similar to adult, but without paragenitals and less developed ; 

 young larva oval, with 5-segmented antennae, a pair of large cephalic 

 tubular ducts, apex of abdomen with long setae, two pairs of lobes 

 and gland spines. 



Genus PHAULASPIS Leonardi. 



Plate 5, fig. 4. 



Genotype. — Asjndiotus haJceae Maskell. 



Reference.— F^viidildi, Cat. Cocc. World, 1903, pp. 251, 260. 



Leonardi first established the genus Phaulaspis in 1897, designat- 

 ing haheae as the type. Later, in 1900, he substituted Cryptaonidia^ 

 with the same type, for Phaulaspis^ but without an explanation of 

 his action. There appears to be no question but that the first name 

 has precedence over the later one. 



The Maskell collection contains eight slides of this species, two 

 of " adult female, 1895," one of " male, 1895," one of " male pupa, 

 1895," one of "larva, 1895," one of "1st pellicle 2, 1895," one of 

 " 2nd pellicle $ , 1895," and one of " pellicles 2 1895." There is also 

 some unmounted material under No. 483,
