CIXIUS SIMILIS. 23 



and obscurely mottled. Costal granules variable in 

 nuraber, and rather larger than those on the other 

 nerves. Nervures indistinct, mostly indicated by 

 minute rows of dots. Stigma indistinct. Legs yellow. 

 Frons and clypeus black, with yellow keels. 



Habitat. — Woking, Hastings, Bonchurch. Mr. J. W. 

 Douglas captured this insect on the sallow thorn 

 {Hippophae rhainnoides), a shrubby plant growing on 

 the sea-shore at Deal, and in other places. I also have 

 three examples from Brockenhurst, in the New Forest, 

 Hants. 



Expanse, 11-48 millimetres, or 0*450 inch. 



The similarity between this insect and C. simplex is 

 great, but there is a difference in the opacity of the 

 elytra. The form of the styles, as drawn by Scott, 

 does not appear to me to differ much, and such a 

 variation in shape might be due to a different aspect 

 of view. 



Similar remarks may be made as to Mr. Edwards' 

 proposed new species, C. remotus, the diagnosis of 

 which seems little to differ from that he gives of 

 C. similis, Kbm., save in the costal spots, nine or ten, 

 against eight to ten ; and elytra lacteo-hyaline, against 

 pale brown. But one example at the date of his 

 Synopsis seems to have come under Mr. Edwards' 

 observation. 



The antennal setae of Cixiidae are very short, and 

 do not project much beyond the eyes. Sometimes, in 

 the figures I have drawn, they appear too long for 

 strict accuracy. 



As a general help towards the discrimination of 

 species, a Synoptical Table is appended. It has been 

 constructed mainly on the lines of Mr. Edwards' 

 scheme ; but I do not look on it as a natural, but only 

 as a convenient, mode of grouping these insects.
