DIAREUSA. 
Diareusa, Walker, List Hom., Suppl. p. 43 (1858). 
This is a well-marked genus, and, according to Walker, “connects Phrictus and 
Hotinus*, resembling the former in the structure of the fore wings, and the latter in 
the structure of the head.” This is but a statement of apparent resemblance or rough 
approximation to the position of the genus; it, however, seems best placed after 
Phrictus and before Enchophora in this enumeration. 
Diareusa, according to our present knowledge, contains but one species, and that 
apparently confined to Central America and the Colombian subregion. 
This generic name has apparently been overlooked ; it is not included in the ‘ Nomen- 
clator Zoologicus’ of Mr. Scudder, nor has Stal referred to it in his ‘“ Conspectus 
Generum ” of the American Fulgoride.

Mr. Champion has contributed the following note respecting this species :—‘“ The 
colour of the tegmina changes after death ; during life it is a mossy green, which 
makes the insect difficult to distinguish when resting on mossy tree-trunks. Only found 
in forests of high elevation.” 
AMYCLE. 
Amycle, Stal, Stett. ent. Zeit. xxii. p. 148 (1861) ; Hem. Afr. iv. p. 186 (1866); Stett. ent. Zeit. 
xxxi. p. 291 (1870). 
Cyrpoptus, sect. ii. Amyele (sic), Stal, Berl. ent. Zeitschr. vi. p. 305 (1862). 
This genus I only know from Stél’s description and Prof. Westwood’s figure of the 
typical species. It is evidently, from the structure of the cephalic protuberance, allied 
to Diareusa. 
Had Stal lived, he would doubtless have catalogued the Homoptera with his usual 
lucidity and thoroughness. It becomes, however, both a puzzle and waste of time to 
attempt to unravel the many genera he founded in this family éither without specifying 
types, or alluding to such subsequently, in other publications of a miscellaneous
