the Coccid genus Leucaspis. 461 



rather doubtfully distinct from that species. The charac- 

 ters of the adult females are, as far as I can see, identical. 

 The most noticeable difference is in the form of the pygidial 

 lobes of the nymphal pellicle, which are conspicuously 

 tricuspid in japonica (see fig. 7), while in riccae — though 

 varying to a certain extent — the margin of the lobes is 

 comparatively entire. Originally described from Japan, 

 the species has since been recorded from Brazil. I have 

 also received it from India, where it occurs on Ficvs 

 religiosa. (See further particulars below.) 



L. kelloggi, Coleman. Coleman's species, as pointed out 

 by Lindinger, has none of the characteristics of the genus 

 Leucaspis and is probably referable to Lepidosaphes. 



L. kermanensis, of Lindinger, is characterised by the 

 comparatively simple margin of the pygidium of the adult 

 female, which is without either plates or prominent lobes. 

 As noted above, the same author's indiae-orientalifi 

 approaches this species very closely. In solids, mihi 

 (described below), a similar condition occurs. 



L. leonardi, Ckll. This is now recognised, by both 

 Leonardi and Lindinger, as a synonym of pusilla. 



L. loewi, Colvee. Both Leonardi and Lindinger agree in 

 regarding loewi and sulci as representing a single species ; 

 but they differ in their opinion as to which of the two names 

 should be retained. While Leonardi accepts leowi as the 

 older name, Lindinger disputes its authenticity and adopts 

 Newstead's name — sulci. 



L. monophylla, Murray. Little seems to be known about 

 this insect, except that it was recorded as occurring on 

 pine trees in Europe. Lindinger places it on his list, with 

 a query. Mrs. Fernald relegates the name to her list of 

 " species without description or not recognisable," and 

 adds a note — on the authority of Cockerell — that it is 

 " probably a Monophlebus." 



L. pini, Hartig. This name — as regards its synonymy 

 with Candida, Targ. — is in the same position as leowi with 

 sulci. Leonardi accepts pini, while Lindinger rejects that 

 name and adopts Candida. 



L. pistaciae, of Lindinger, is well characterised by the 

 single pair of large median lobes on the pygidium of the 

 adult female. 



L. pusilla, Loew, shows a curious variability of the mar- 

 ginal fringe. The plates may be either spatulate, or 

 irregularly serrate, or both conditions may occur together.
