 J. A. S. Beng. vol. Iv. p. 153 (1880). 



Body of moderate size, somewhat slender. Head, including eyes, about equal in width to base of 

 mesonotum. Ocelli about equally wide apart from eyes as from each other ; rostrum extending to or a 

 little beyond the intermediate coxm. Pronotum witli the lateral margins more or less convex, narrower in 

 front than behind, the posterior lateral angles in some species distinctly posteriorly produced. Anterior 

 femora prominently spinous. Tympana completely exposed and uncovered. Opercula small. Face more 

 or less longitudinally sulcated. Tegmina more or less opaquely coloured ; apical areas eight (sometimes 

 nine or ten) ; basal cell much longer than broad. Wings either transparent or infuscated and partly 

 opaque. 



This genus is strictly confined to the limits of our fauna, and some of its species are not 

 only widely distributed, but also very variable in tlieir coloration. The rule holds throughout 

 the CicadidiiD that all mclanic species vary towards albinism, and Hmchys is no exception to 

 the rule. Guided by this experience, I have been able to group as varieties many forms which 

 were incomprehensible under distinct specific names.
