tionship, so the o:enus aj^pears actually to be rather anomalous among 

 the Coccinae and may stand alone as a distinct tribe when the generic 

 classification of this subfamily is reorganized. 



Genus PARALECANIUM Cockerell. 

 Plate 4, fig. 5. 



Genotype. — Lecanium frenchii Maskell. 



Reference. — Fernald, Cat. Cocc. World, 1903, p. 199. 



The type of this genus was specifically designated as being Le- 

 canium frenchii Maskell at the time Professor Cockerell erected the 

 subgenus Paraleccmium^ which he later raised to generic standing. 



The Maskell collection includes three slides of the type species, one 

 of " adult female, Aug. 1890," one of " antenna of female, Aug., 1890," 

 and one of " 2nd stage female, Aug., 1890," besides which there are a 

 few unmounted specimens under No. 131. 



Adult female.- — Flat, broad oval, dorsal derm heavily chitinized, 

 dark brown; derm clearing only a little when boiled in potassium 

 hydroxide; body with clear radial lines extending part way in to- 

 ward the center all the way aromid the margin, these continued as 

 large areolations in the middorsal region ; antennae small, slender, 

 8-segmented; legs small, slender, normal, claw apparently without 

 denticle, digitules slender, knobbed at apex; spiracles small, slender 

 in middle; mentum small, short, 1-segniented ; marginal flabella 

 small, faintly striate, triangular with rounded corners, not overlap- 

 ping; spiracular spines in threes, the middle one somewhat longer, 

 all slightly clavate; dorsal surface with an occasional small slender 

 hair, ventral surface with two pairs of relatively large setae anterior 

 to the anal ring, and with scattered minute setae; derm with occa- 

 sional clear pores through the chitin dorsally, probably representing 

 the openings of tubular ducts, although details of such can not be 

 made out, ventrally with a row of tiny quinquelocular pores between 

 each spiracle and its marginal spines, similar pores in all probability 

 present in the ventral anal region, although here again they are not 

 observable; anal plates elongate, triangular, posterio-lateral margin 

 somewhat longer than anterio-lateral ; anal plate setae very few, only 

 a single submedian one observed dorsally, apparently without apical 

 setae, and with only a single fringe seta ventrally, these very small, 

 and possibly with a few more present; anal ring small, stout, nor- 

 mally placed anterior to the plates, with pores and six long setae. 



Intermediate stages. — None available for examination. (Maskell's 

 2nd stage female apparently a late first stage larva.) 



Larva. — (Maskell's 2nd stage female.) Only one specimen badly 

 attacked by fungus, so that nearly all the characters are obscured, 

 those visible shown in figure.
