synonymy of this species will show the general style of Mr. Walk- 

 er's determinations in the moths correctly. The species represents 

 in our fauna the European Calpe thalictri. 



Lygrantlioeciaj Orote and Bohinson (1873). 



This genus differs from Heliotlds in its slender and elongated body parts, 

 and less hairy squamation. From the section Melicleptria by the more 

 rounded thorax. The naked eyes have a short frilling of scales beneath. 

 The front is much flatter than in Heliotlds, and the palpi are more porrected. 

 The frontal scales are not mixed with hair, nor twisted towards a central 

 point, as in that genus. The habitus is more like Lepipolys, or even Schmia. 

 The shape of the abdomen is like IleliotMs proper, but the $ oviduct is 

 shortly salient and dependent. All the tarsi spinose, hind tibiae with two 

 pair of spurs ; middle tibiae with a single unequal pair, whereof one spur 

 very long; fore tibia with terminal spines. The squamation is peculiarly 

 pearly and powdery ; the fore wings are divided into fields, as in some species 

 of Heliotlds, but the sombre hind wings and under-surface do not recall the 

 gay coloration and ornamentation of that genus. 



This genus was in manuscript at the time of Mr. Eobinson's 

 death. It had been remarked by him that the typical species, 

 Anthoecia rivulosa, had been unjustly used by Dr. Ilerrich-Schaeffer 

 to criticise Lederer's definition of Heliothis.

Pyralis marginattts, Haworth.

Habitat, Massachusetts to Alabama. The European Chariclea 

 umbra, has for its synonym Heliothis marginata,\Qmmg the specific 

 name eligible for this species.
