ART. 12. MASKELL. GENERA OF COCCEDAE MORRISON. 41 



Genus EPICOCCUS Cockerell. 



Plate 3, fig. 1. 



Genotype. — Coccus acaciae Maskell. 



Reference.— F^YYiiAd, Cat. Cocc. World, 1903, pp. 88, 89. 



This genus as established by Professor Cockerell included only the 

 type species, and none have been added to it subsequently. 



There is a small number of unmounted specimens with the Maskell 

 No. 505, one slide labeled " adult female, 1896," one " antenna and 

 feet of female, 1896," and one " larva, 1896," under this name in the 

 Maskell collection. It has been possible to obtain an additional 

 aioimt of an adult female and a larva from the unmounted material, 

 and these have proven to be of considerable assistance in preparing 

 the following description. 



Adult feiiiale. — Body, as stated by Maskell, dark red, usualh^ 

 much wrinkled, more or less globular or somewhat conical above, 

 naked except for some ventral secretion, resembling some Antonina 

 species in this respect ; fully mature form, when boiled in potassium 

 hydroxide expanding to an almost spherical sac, with the ventral 

 surface slightly flattened; antennae small, 6-segmented, typically 

 Pseudococcine in appearance ; legs small but otherwise normal, claw 

 without denticle, digitules normal, slender, knobbed, hind coxae with 

 numerous pores ; mouthparts small, mentum apparently 2-segmented ; 

 dorsal ostioles obscure ; with only the two posterior pairs of cerarii 

 present as such, the remainder of the margin of the ventral surface 

 with a continuous band of trilocular pores and short, slender, taper- 

 ing but blunt-tipped spines, together with an occasional slender seta, 

 the cerarian spines slender, acute at apices, somewhat lanceolate, and 

 considerably larger than those of the band ; spines of band clustered 

 more or less, although \Q,vy indistinctly, into small groups with only 

 pores intervening; anal lobe cerarii set on small protuberances, each 

 accompanied by a slight chitinized area and each composed of from 

 10-15 lanceolate spines, accompanied by a somewhat larger number 

 of small triangular pores; with a relatively large and stout apical 

 seta below, but this shorter and more slender than the anal ring 

 setae; without ventral chitinized thickenings; anal ring small, with 

 pores in an inner and an outer row on each half, with six relatively 

 large, stout setae, placed dorsally quite a distance from the apical 

 cerarii, as compared with other Pseudococcine forms, and at the 

 inner end of a short delicate membranous tube which is much longer 

 below than above: with the two long setae usually occurring below 

 the anal ring in Pseudococcus and related forms placed directly be- 

 tween the two apical cerarii and at a distance from the ring; derm, 

 so far as noted, with three types of pores, the usual trilocular. trian- 

 gular pores, occuring in the cerarii, the marginal band and wideltr
