II.— MEMBEACINA. 



G-en. CENTROTUS, Fab. 

 The pronotum is produced into a horn on either side, and into a 

 long ensiform process behind, which arches over, but does not conceal, 

 the scutellura, and reaches nearly to the apex of the abdomen. 

 l. — Oentrotus cornutus, Lin. 

 Piceus, pube brevi aurea adpressa vestitus. Hemelytra fusco 

 hyalina, nervis tautum pubescentibus. Caput, pronotum, scutellum, 

 ruguloso punctata. ? . Long. lin. 3|-4.

 This insect has a wide range, and has been observed through 

 Europe, from the Ural mountains to France, and from Sweden to the 

 Mediterranean. It is far from uncommon in woods in this country, 

 but I have never seen a ,^ , nor does any notice of that sex appear in 

 the authors I have examined. It is said to frequent wiUows and 

 thistles. 



Gen. oxYEEHACHis, Germ. 



Pronotum laterally angulated, but not prominently cornuted as in 

 the preceding. The posterior process is shorter than in Centrotus, not 

 arcuated, and it entirely conceals the scutellum. 



1. — Oxyrrliachis genistas, Fab. 



Precedente quintuple minor ; piceus, punctatus, aureo-pubescens. 

 Hemelytra flavo-hyalina. Long, lin. \\.

 Flor., R. L., 2, p. 106. 



Rare ; inhabits Genista tinctoria (Lin.) My specimen was taken 

 at Purfleet, in August. This is, perhaps, the only European species of 

 the genus ; the rest are thinly distributed over Asia, Africa, and South 

 America. I possess one other nearly allied form, wliich I took on the 

 lesser Atlas, in Algeria.

*^* The writer of the above article will have great pleasure in 

 naming collections of British Auchenorhyncha, for those Entomologists 

 who think it worth while to take up the study. He will also gladly 

 impart duplicates to the extent of his resources, and will be thankful 

 for assistance in the shape of new species.
