arched, fuscous, more distinct towards the inner-margin, and 

 several times interrupted ; through the central line, just below 

 the central vein, runs a short longitudinal fuscous streak ; the 

 hind line exteriorly margined with whitish. Hind -margin 

 brownish-yellow with black spots. Cilia grey, shining. Some- 

 times the only distinct markings are the central longitudinal 

 fuscous streak and the lower half of the hind line. 10^-12 L. 



August. Central and Southern Europe. Not uncommon in the south, rarer

 rather elongate, acute ; grey or brownish grey j the broad cen-

July, August. Europe, except the polar regions. Rather a local species in 

 Britain. In Scotland it has only been detected uear Edinburgh. It occurs in 

 dry pastures. 



Note.— These three species may be easily distinguished from each other: — 

 i?iqui?iatellas, by the slightly arched lines, and slightly shining cilia : geniadeus, 

 by the acutely angulated lines, and shining cilia ; contamincllus, by its duller 

 colour and cilia. 



", Cilia scarcely shining in most of the species. Front 

 tcings dull. No central line; the hind line (if any trace of it is present) may be
