564 Mr. Jolm Scott'ss Muiwgrajili of the 



end -of August. I liavc only seen two examples, one 

 taken by Dr. Power, the other by Mr. Douglas. Forster 

 mentions having received it both from INlessrs. Ilaliday 

 and Walker. 



Genus RiiiNOCOLA. 



Head much broader than long. Crown deflected, with 

 a shallow fovea on each side : central channel obsolete ; 

 anterior margin convex ; posterior margin faintly concave. 

 Ocelli as in Aphalara. Face without lobes. AntenncB 

 10-jointed, very short; 9 — 10 slightly thickened, 3rd 

 elongate, 4 — 10 about equal in length. Eyes placed ou 

 the side of the head ; outer margin convex. 



Thorax: provotain narrow, somewhat deflected or 

 horizontal ; lateral margins about in a line Avith the outer 

 margin of the eyes. Eli/tra not transparent, somewhat 

 lanceolate ; apex rounded ; costal margin more convex 

 than the dorsal one ; stigma distinct. 



In this and the preceding genus the crown and face 

 appear as continuous, and not separated as in Psylla and 

 Trioza. 



Differs from Aphalara in the shape of the head and the 

 elytra, and moreover possesses a stigma. 



The species of this genus are minute. 



Species 1. Rhinocola erica. 



Psylla Erica, Curt. B. E. xii. 50)5, 25; Rhinocola Erica, 

 Forst. Verb. Ver. llheinl. v. 91, 2; Flor, Kliyn. Livl. 

 ii. 527, 2. 



Green, greenish -yellow or yellow. Antenna yellow; 

 three terminal joints frecpiently brown. Elytra testaceous, 

 semitransparent, finely Avrinklcd transversely. 



Head: croicn, posterior margin straight. Antenna 

 yellow; 8 — 10 joints frequently bi'own. 



Thorax: /^ro- and meso-notian green, greenish-yellow or 

 yellow. Elytra testaceous, semitransparent, finely AAa-inkled 

 transversely, narrowed towards the apex ; disk with or 

 without minute brownish particles. Eeys greenish-yellow 

 or yellow. Claws brown. 



Abdomen green ; genital segments of both sexes yellow, 

 or sometimes in the ? iliintly brownish-yellow. 



Length f line. 



The small size and more broadly-rounded apex of the 

 elvtra will at once establish the difference between this 

 and the IbUowing species. Messrs. AVulkcr and Ilaliday
