XV. Some remarks on the Coccid genus Leucaspis, with 

 descriptions of two new species. By E. Ernest 

 Green, F.E.S.

Plates LXVII, LXVIII. 



The following species have, at various times, been allotted 

 to the genus Leucaspis : — affinis, Leon. ; bambusae, Kuw. ; 

 Candida, Targ. ; cockerelli, de Charm. ; cordylinidis, Mask. ; 

 corsa, Lind. ; cupressi, Coleman ; ephedrae, March. ; epi- 

 daurica, Genn. ; gigas, Mask. ; indica, Marlatt ; indiae- 

 orientalis, Lind. ; japonica, Ckll. ; kelloggi, Coleman ; ker- 

 manensis, Lind. ; leonardi, Ckll. ; loewi, Colvee ; monophylla, 

 Murray ; pini, Hartig ; pistaciae, Lind. ; pusilla, Loew ; 

 riccae, Targ. ; signoreti, Targ. ; stricta, Mask. ; and sulci, 

 Newst. 



These twenty-five names have since been considerably 

 reduced in number, partly by allocation to other genera 

 and partly by suppression as synonyms. These changes 

 in nomenclature have been put forward by Leonardi and 

 Lindinger (not always in complete agreement) in two useful 

 papers published in 1906, viz. Leonardi " Saggio di Siste- 

 matica delle Leucaspides," Anneli di Agr., vi; and Lin- 

 dinger, " Die Schildlausgattung Leucaspis," Jahr. Hamb. 

 wiss, Anst., xxiii. 



L. affinis, of Leonardi, in the opinion of Lindinger, is a 

 synonym of Candida, which — in its turn — ^is suppressed by 

 Leonardi as equivalent to pini. Leonardi distinguishes 

 his species from pini by its smaller size and the fewer 

 number of glandular pores outside the anterior spiracles. 

 Lindinger, however, disputes the authenticity of L. pini 

 of Hartig. 



L. bambusae, of Kuwana, is relegated by Lindinger 

 to the genus Lepidosaphes {Mytilaspis of Signoret). 

 Kuwana's figures of his species (Pr. Cal. Ac. Sci., 3, iii, 

 PI. XIII, figs. 75-81) show unmistakably that it cannot be 

 included in Leucaspis ; but, in the absence of male puparia, 

 it might be assigned, with equal justice, to either of the 

 two genera Lepidosaphes or Chionaspis.
