Tarache abdominalis, n. s. 



This species is parallel with aptica and may be distinguished by the 

 blackish abdomen, ringed with white. It varies in the color of primaries 

 and thorax. In some specimens the fore wings are white from the base 

 to exterior line with two dark costal patches as in the type aprica. The 

 exterior line is heavier and more metallic than in aprica. The subterminal 

 line is notably less inwardly projected than in aprica below the median 

 nervules. Again, the fore wings are more or less blackish at base, leaving 

 two white costal blotches as in biplaga. Beneath the two forms are to be 

 quickly distinguished. In abdominalis the wings are yellowish, the hind 

 wings with a terminal blackish band, two discal longitudinal rays from the 

 base and a transverse fascia broadly marked on costa in the best marked 

 specimens ; the rays and transverse fascia become more or less obsolete. 

 Above the hind wings are black or blackish, sometimes pale yellowish on 

 disc, always darker than in aprica. Thorax and head blackish \ tegulae 

 more or less white on the sides. Expanse 25 mil. Hab. Texas (Belfrage 

 No. 596) ; also collected by Heiligbrodt, in Mr. Meske's collection. The 

 colors of the dark outer portion of the fore wings are brighter than in 

 aprica, the band before t. p. line more olivaceous, the subterminal line 

 more tinged with brown. I have to thank Mr. v. Meske for drawing my 

 attention to this form, which from the description cannot be obatra of Mr. 

 Morrison. 



Geontetra rectaria, n. s. 



^ . This species is smaller than iridaria, of a rather more dull green 

 and with one-half narrower white lines. Costa of primaries whitish, much 

 marbled with fuscous. Inner white line of primaries perfectly straight. 

 Outer line extending across hind wings in same position as in iridaria. 

 Minute black discal points on both wings. Fringes concolorous, not 

 paler as in iridaria. Head white ; palpi brown at tips. Legs white with 

 black dots at extremities of second and third joints. Beneath secondaries 

 a little paler than primaries, on which alone the minute black discal points 

 are legible. The common exterior line is indistinctly shown. Tegulae 

 and collar green; dorsum of thorax discolorous. Expanse 25 mil. Hab. 

 Texas (Belfrage, No. 323). 



This species differs from Mr. Walker's descriptions of forms unidentified 

 by Dr. Packard more broadly than from iridaria. The wings and body 

 are proportioned as in iridaria. From the description I should not refer
