6 LECANIINJ3. 



with or without caudal filaments. Genital armature 

 usually with an outer, straight, styliform sheath, but 

 there are important exceptions, notably in Ceroplastes.* 

 The puparium of the male is generally of a glassy 

 nature, but in Aclerda it is felted. 



Larva with large setiferous anal lobes placed within 

 the posterior anal cleft. 



FEMALE vis AC. 



In the genera Aderda, Eriopeltis, Signoretia, and 

 Lichtensia the female forms a more or less complete 

 ovisac (PI. XXXVI, fig. laa; PI. XXXVIII, figs. 1-16; 

 PI. XL, fig. 1 ; and PI. XLI, fig. 1), which is secreted 

 from numerous spinnerets and hollow spines (PL 

 XXXVIII, figs. 2, 4, 5) variously disposed in the 

 different genera. Exceptionally, as in Lecanopsis 

 brevicornis, Newst., the female covers her body with a 

 talc-like or glassy secretion, and a similar kind of 

 secretion is produced by the monotypic genus Vinsonia 

 (PL XLIII, figs. 2, 3, 11), which assumes the remark- 

 able form of a seven-rayed star. 



With Pulvinaria (PL XLV, fig. 1) the female remains 

 naked throughout life, but secretes an ovisac in the 

 form of a pad or cushion beneath the posterior part of 

 her body. In P. camellicola (PL XL VIII, figs. 1, 2) 

 the ovisac is many times longer than the body of the 

 insect, but such forms are exceptional. Ceroplastes (PL 

 XLII, figs. 1-1 c, 11), one of the most beautiful 

 members of this division, covers her body with variously- 

 shaped, testudiform plates of wax, often delicately 

 tinted with pink or crimson. 



The females of the typical genus Lecanium are naked 

 in all stages, and the body, whether flat as in L. 

 hesperidum (PL L, figs. 2-5, 10), or hemispherical as 

 in L. hemisphzericum (PL LVI, fig. 1), forms a covering 

 for the ova and the young larvse.
