between the basal joints (whicli is sometimes continued on the 

 face as a short longitudinal line) ; in the middle are two parallel 

 slightly interrupted longitudinal lines on the triangular elevated 

 portion ; and the superior orbits have a spot or baud (all these 

 markings more or less blackish brown). Palpi nearly black ; the 

 articulations and the apex of the terminal joint pale. Pronotum 

 longer than broad, the sides nearly parallel ; broadly margined on 

 each side with blackish, forming broad lateral bands not quite 

 complete, but more or less broken up by spots of the pale ground- 

 colour. These marginal bands are more or less continued on 

 each side of the meso- and metaiiotum, but are there much broken 

 up into spots. Pectus and pleurce green, more or less lined and 

 spotted with black ; pronotum wholly green. 



Abdomen green, spotted with black on the sides (but arrange- 

 ment not definable in dry examples) . 



Legs pale green, with minute black hairs ; tarsi dusky ; cJaios 

 simple (not suddenly dilated internally), testaceous. 

 ; Wings moderately broad, the anterior scarcely acute at the 

 extreme apex, the posterior more decidedly acute. In the ante- 

 rior there is a conspicuous black spot near the base of the costa, 

 another at the extreme base of the radius, another (sometimes in- 

 distinct) in the small anal area, and another {triangular and very 

 distinct) near the base of the inner margin at the termination 

 of the first postcostal uervule, which is somewhat incrassate ; 

 all the longitudinal nervures ^j«Z^, the reticulation otherwise 

 loholly hlack ; the partition nervule of the third cubital cellule 

 ending only slightly beyond the nervule above it ; 5 nervules in 

 the inner gradate series, 7 in the outer ; short black hairs on 

 all the reticulation ; pterostigma slightly dusky. Posterior wings 

 with a small blackish spot near the base of the costa ; reticulation 

 coloured as in the anterior. 



Expanse 30-31 mm. Breadth of anterior wing 5-5^ mm.

 Amongst European species this is decidedly nearest to Ch. Genei*, 



* In Schneider's monograph C'/i. Genci is placed in a st'ctioii (p. fi3) charac- 

 terized by the words "Secundo aiitenuariim articulo bnmneo aut nigro colore 

 ciucto." In order to prevent misapprehension, it is necessary to state that this 

 character is not constant in Geiici. On the other hand, there are indications 

 that the second joint of the antenna; may sometimes be blackish or brownish in 

 fortvnata. The character fails as sectional (even if applied to its most typical
