274 COCCID/E OF GUERNSEY. 



with that of Lecanium tilice, Lin., for instance, the only 

 appreciable difference will be found in the arrangement of 

 the hairs on the anal ring, a character which would hardly 

 separate them generically." 



A full description of the adult female and larva is 

 published by Mr. Newstead in the Entomologists' Monthly 

 Magazine for September, 1894. Figures are also given of 

 the two-jointed anterior tarsi and the eight-jointed antennae. 



Dactylopius Luffii, Newstead. — A species new to Science 

 discovered by myself on September 14th, 1899, on the coast 

 near Richmond during one of the Society's numerous ex- 

 cursions to that locality. They occurred in thick clusters 

 on the lower stems and at the roots of Lepigonum rupestrc, 

 and were very lively. Mr. Newstead, to whom I sent 

 specimens, said " the agility of these little ' mealy-bugs ' 

 was remarkable and certainly not equalled by any other 

 Coccid I have observed." This species has hitherto only been 

 found in Guernsey. A full description of this species is 

 given by Mr. Newstead in the Entomologists' Monthly 

 Magazine for April, 1901. 



Ripersia Tomlinii, Newstead. — This is a most interesting 

 insect ; it was first discovered by Miss Tomlin, of Chester, 

 whilst searching for Coleoptera at Moulin Huet, in September, 

 1891, and forwarded to Mr. Newstead, who named it after 

 the discoverer. A description of the larva and adult female 

 is published by Mr. Newstead in the Entomologists' Monthly 

 Magazine for June, 1892. The male is unknown. 



In the following year (April, 1893) Mr. Newstead 

 published the following interesting notes on the species : — 



" When the description of this species was published, 

 I was unable to furnish the names of the ants in whose nest 

 the Coccids were found. On subsequently reading Mr. 

 Smith's interesting remarks on the " Origin of Ants' Nests " 

 (Unto. Mo. Mag., Vol. III., pp. 60-307) I was all the more 

 anxious to ascertain the name of the ants, and to get a 

 further supply of Coccids and information. The only course 

 open to me was to write to the Secretary of the Guernsey 

 Society of Natural Science to put me in communication 

 with a member who would be willing to take the matter 

 in hand. This I did, and Mr. W. A. Luff kindly offered 

 his services, and on August 1st, 1892, forwarded two speci- 

 mens of the Ripersia, together with specimens of the ants 

 as they were found. Mr. Luff remarked 'that they were 

 found under a stone on the cliffs near Moulin Huet Bay. I 

 searched carefully in nests of other species of ants, and
