Lygranthcecia Balba. n. s. 



Fore wings faded ochrey, shaded with fuscous within the 

 curved basal line. A dark reniform spot, near the outer line. 

 The lines somewhat incomplete. The outer line is broken into 

 dark spots below median vein. The subterminal space darker^ 

 constricted by the very pale tint of the terminal space opposite 

 the disc. Hind wings blackish over whitish ; the interlined 

 fringes whitish at base. Body pale ochrey. Beneath very pale 

 ochrey ; on fore wings the blackish stigmata, the outer line, and 

 dark s. t. space rather well marked. On fore wings above, the 

 marginal line is broken into dots. This form appears to belong 

 to the Separata group. Expanse, 25 mil. A number of specimens 

 examined. An inconspicuous fady species, with the darker 

 shades of the primaries giving them a soiled appearance. 



In Lygranthcecia Marginata, the type of the genus, the eyes 

 are naked. The fore tibiae have, on the outside, four stout blunt 

 spines in a decreasing series towards the base of the joint. On the 

 inside there is first a long spine opposite to the longest of the out- 

 side series, at the extremity of the joint ; these two spines embrace 

 the base of the tarsi. There is then a second long spine on the 

 inside of the tibise, followed by a very short one. All the tibiae 

 are armed. With this, the new form L. Balba, disagrees by the 

 slenderness of the two inside spinules on the front tibiae, and the 

 presence of but three spines on the outside. The genera of the 

 Heliothid group need revision, as the species are numerous. For 

 the present I keep the genera already established, and refer the 

 species with ornamentation after the pattern of Lygranthcecia, 

 to that genus, until the armature and genitalia of each species 

 can be studied and compared. 



Lygranthcecia Coercita, n. s. 



In my collection is a species from Nevada, allied to Balba in 

 appearance, but differing by the presence of four blunt spines on 

 the outside of the fore tibiae. It is very pale and differs from 

 Separata by the hind wings being white. Primaries faded ochrey 

 with the lines white. S. t. space narrow, constricted by the broad 

 white s. t. line opposite the cell. Reniform long, discolorous, 

 defined, extended inferiorly; orbicular, marked. Terminal line 

 dotted. T. p. line not so much exserted, opposite the disc, as 

 usual. Head and thorax nearly white. Same size with its allies. 

 This form is perhaps nearest to Separata, but the ground color is. 

 as pale as Regia, in which the subterminal space is not constricted 

 opposite the disc, and the fine rosy purple color is very different 

 from the faded ochrey shading on the primaries of Coercita. 



With regard to the moths, very incompletely described by 

 Mr. Stecker under ^^ HcliotJiis,'' but not figured, I have been able 

 to find out eight species. They belong, evidently, to different 

 genera, and not a few of them are synonyms. HcliotJiis ijuper- 

 spicua of Mr. Strecker is SCHINIA Gracilenta of Hubner ; H.
