Allied to X. quadrimaculatus and X. hrunnidorsis, Mars., but differing 

 from both in the maculation of the elytra ; the antennae are shorter 

 than in the same sex of either of these species and entirely piceous, 

 except the tip of the last joint. The female, doubtless, has shorter 

 antennae. Allied forms inhabit Central America. 



In Marseul's collection an example of this species (received from 

 Mr. Gr. Lewis) does duty for X. q^uadrimaculatus ; a male of the latter 

 before me differs from the same sex of X. japonicus in the longer and 

 entirely reddish-testaceous antennte, in the longer thorax, and in the 

 elytra being reddish-testaceous, with an elongate-triangular scutellar 

 patch, a common transverse fascia beyond the middle, and the suture 

 indeterminately piceous.

TWO SPECIES OF FSOCID^ NEW TO BRITAIN. 

 BY ROBERT McLACHLAN, F.R.S., &c. 



Elipsocus consimilis, n. sj). 

 Closely allied to JE. cyanops, Rostock, possibly slightly larger. Pale yellow ; 

 eyes and ocelli black ; artennse strong, black, pale at the base. Dorsum of thorax 

 and abdomen more or less infuscate. Legs pale yellow ; tarsi blackish. Wings 

 hyaline : in the anterior the neuration is stronger than in cyanops, and the black 

 dots at the commencement of the pterostigma and the end of the anal vein are much 

 more conspicuous ; posterior areole obtuse at the top, but apparently less rounded 

 than in cyanops. 



I beat about a dozen examples from Pinus sylvestris, at West- 

 bourne, near Bournemouth, on August 28th, 1890, and I find five 

 examples from Tuddenham Heath, Suffolk, June 27th, 1880, mixed 

 with E. cyanops in my collection. 



Having compared a series of examples of E. consimilis with a 

 like series of undoubted E. cyanops, I am forced to the conclusion 

 that the former is distinct. They do not mix themselves locally, and 

 the characters pointed out appear to be constant. The body colour 

 of co7isimiUs is less bright, and this is heightened by the obscure 

 coloration of the dorsum of thorax and abdomen. When alive, 

 cyanops is very bright, and the colour gives the idea of being pale 

 orange, not at all noticeable in consimilis. My old specimens from 

 Tuddenham quite agree with those from Bournemouth.
