AliCIITKNSIA, geti. nov. [Lecannnce). 



Female scale elongate, with a glassy covering, much like 

 the male scales of Lecaniinaj; a little felted matter, in threads, 

 is visible on the underside ot the glassy scale. No rows of 

 air-cells. No ovisac. Antennai and legs well developed. 



'J'yjjc, Alichtensia atteniuita [Lichtensia (?) attennatii, 

 Ilenipel, Hev. Mus. Paulista, iv. p. 41)4). 



The genus is allied to Ceroplaslodes and Layosinia. 



AusTROLiciiTENSiA, gen. nov. {Lecannmc). 



Female enclosed in a sac which has an elongated dorsal 

 aperture. Margin of female with very long bristles. An- 

 teiiiiai and legs well developed. Skin with numerous tubular 

 glands. Anal ring with six hairs.

Philephedha, Ckll., 1898. 



'i'he type is PhiUphedra (phedrcb [Pulvinaria eyhednv^ 

 Ckll.). 



riiihpliedra was described as a subgenus of Fulviuann, 

 but recent studies show that it is in reality closer to Lich- 

 tensia. The sharp marginal spines are just such as are found 

 in Lichtensia crescentice, mimosa', lutea, &c., though L. vi- 

 hurni — the type of Lichtensia — has tiiese bitid at the end. 

 If Philephedra should be considered only a subgenus of 

 Lichtensia, then Lichtensia ephedrce, Newstead, would have 

 to be renamed. 



Neolecanium, Parrott, 1901. 



Tliis name was proposed as a subgenus of L^ecanium ; it 

 seems best to regard it as a valid genus. It contains the 

 following species, hitherto referred to Lecanium : — A. ivdni' 

 catum (Ckll.), iV. Urichi (Ckll ), N. perconve.vurn (Ckll.), 

 iV. tuberculatum (Twns. & Ckll.), A\ Silveirai (Hempel). 

 The two following are referred here provisionally : — N. chi- 

 laspidis (Ckll.), N. ISallei (Signoret). All of these are 

 Neotropical. 



Mesolecanium, gen. nov. [Lecaniina). 



Type, M. noctumum {Lecanium noctiirnum, Ckll. & Par- 

 rott, Biol. Ceiitr.-Am., Khyn. Ilomop. vol. ii. |)t. 2, p. 13). 

 This appears to be the form from whicli Neofecaniuoi was
