To [.Linuary, 



In 1872, toads were remarkably plentiful in the neighbourhood of 

 Tenby, S. Wales, and I noticed that the disease was very prevalent 

 amongst them. In the following year scarcely any could be found, 

 and I saw none diseased. A similar sequence of events took place 

 in the Isle of Wight, in the years 1887, 1888.

OBSERYATIONS ON COCCIDM (No. 9), 



BY ALBEET C. T. MORaAN, F.L.S. 



Genus UHLERIA, Comstock. 

 FIORINIA, Targ.-Tozz. 



This genus, established by Comstock, is the same as the genus 

 Fiorinia, which was indicated by Targioni-Tozzetti to include one 

 species. The latter author at first named the species Diaspis Morinice 

 (Stud. s. Cocc, 1867), and afterwards in his Catalogue (1868) re- 

 named it Fiorinia pellucida. Prof. Comstock (2nd Eep. Corn. Un. 

 Exp. St., 1883, p. 110) gives reasons for reverting to the name Fiorinia 

 for specific purposes, and adopting a new generic name, which he 

 states is in accordance with the rule of nomenclature among zoologists. 

 I have, therefore, followed his ruling, although Mr. Maskell prefers to 

 maintain the original name of the genus, viz., Fiorinia (New Zeal. 

 Sc. Ins., p. 57). 



1. Uhleria Fiorinia. 



Fiorinia camellicE, Comst., Ag. Eep. (1880), p. 329, pi. xi, fig. 7, pi. xix, fig. 4. 

 UJileria camellice, Comst., 2iid Rep. Corn. Un. Exp. St. (1883), p. Ill, 

 pi. ii, fig. 9. Diaspis Fiorinice, Targ.-Tozz. (1867), Stud. s. Cocc, pp. 

 14, 42. Fiorinia pellucida, Targ.-Tozz. (1868), Cat., p. 42; Sign., Ess. 

 s. Coch., p. 131, pi. ii, fig. 2. Chermes arecce, Boisd., Ins. Ag. (1868). 

 Uhleria camellice, Morg., Ent. Mo. Mag., vol. xxv, p. 46, pi. i, fig. 1. 



Although Prof. Comstock did not consider this species identical 

 with Fiorinia pellucida, described and figured by Signoret, yet I cannot 

 help thinking that the species which I have examined and which is 

 clearly the same as Comstock's species, is also the same as that of 

 Signoret and Targioni-Tozzetti ; and, in that case, if we maintain 

 Comstock's new name for the genus, then the original name Fiorinice of 

 Targioni-Tozzetti should be restored for the species. I have observed 

 in some specimens of the larva the two processes between the antennae.
