A REVISION OF TIIK DKLTOID MOTHS SMITH. 71 



Expanse of \viii<;s, li3 to -57 mm. = O.JM) to l.OS iiichcs. 



Habitat. — Florida. Arclier in February, Itock Lcdo-ein A])rii; Savan- 

 nah, Ga. 



Twelve specimens are before me, showing- little variation, l)nt a (;on- 

 stant sexual ditierence in color. The males have, in all cases before me, 

 the described markings, though not equally evident, wliile in all the 

 females the subt<'rminal line is the only distinct feature, tliouuli the 

 reniform is usually very well marked. 



In the male the palpi are a little shorter than tlicN are in the rcinale, 

 and are somewhat obliipie, and in this sex the wings are also a lirtle 

 narrower. 



It is (piite certain that this species has been confused in collections, 

 the males with h\ salusalis and the females either with that sjiecies or 

 with J\'. sohrialis, which they resend)le in wing form. 



In size the species is much below the average of E. tialumlis, and 

 eqnals R. sohriaUii, though I have seen some extremely small specimens 

 of B. salusalis (20 mm.). 



The species seems not uncommon in its range. 



Renia sobrialis, \\";ilker.

Ground color smoky brown to blackish, powdery. Head and thorax 

 concolorous. Primaries with the maculation obs(;ure. Transverse 

 anterior line irregularly outcurved. Transverse posterior line barely 

 traceable, punctiform, as a whole nearly pai-allel with the outer margin. 

 Subterminalline pale, slightly irregular, usually interrui)ted, sometimes 

 ])iinctiforni, occasionally almost obsolete, marked by a i)receding dusky 

 shade, which becomes broken into si)ots when the line is punctiform, 

 sometimes appearing- as a series of dark, white centered blotches. 

 Median line traceable below the median vein in some specimens. A 

 series of black terminal dots or marks. Orbicular a small yellow dot 

 which is sometimes wanting. Reniform ni»iight, narrow, yellow, with 

 moie or less obvious black points at the extremities. Secondaries 

 scar(;ely paler than {nimaries, with a dusky extra median and a pale 

 subterminal line; both barely traceable. Beneath smoky, coarsely 

 powdered, with a dark extra-median and i)ale subterminal line, the 

 latter rarely distinct. 



Expanse of wings, 23 to 2(1 mm. = 0.!t2 to 1.01 inches. 



Habitat. — Nova Scotia to N'irginia, Central States; District of 

 Columbia in August; Colorado in Septend>er. 



Mr. (rrote gives the expanse as 27 to 28 nun., which is greater than 

 any I have seen, and greater than his ty])e sp<M'imen in the collection 

 of the American Entomological Society, in the s[»ccimens before me
