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. 
Lygranthoecia, Grote and Robinson (1878). 
This genus differs from Heliothis 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 Heliothis, 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 Schinia. 
The shape of the abdomen is like Heliothis 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 Heliothis, 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. Robinson’s 
death. It had been remarked by him that the typical species, 
Anthoecia rivulosa, had been unjustly used by Dr. Herrich-Schaeffer 
to criticise Lederer’s definition of Heliothis. 
Lygranthoecia marginata, Grote and Robinson. 
Pyralis marginatus, Haworth. 
Anthoecia rivulosa, Guenée. 
Habitat, Massachusetts to Alabama. The European Chariclea 
umbra, has for its synonym Heliothis marginata, leaving the specific 
name eligible for this species. 
Lygranthoecia Thoreaui, Grote and Robinson. 
Anthoecia Thoreaui, Grote and Robinson, Trans. Am. Ent. Soc., Vol. 3, p. 
181, Plate 2, fig. 80, 1870. 
Habitat, Pennsylvania to Alabama. 
Heliolonche, Grote. 
Antennae scaled, pubescent beneath in male, simple in female, in which sex 
the ovipositor is exserted as in Melicleptria; ocelli; front full, not convex ;
