A REVISION OF THE DELTOID ISK^TIIS SMITH. 117 



usually mucli darker, .yray or smoky iu its shadings, without marked 

 contrasts, yet as a rule the markiuiis fairly evident. Tlirou,i;h the 

 costal region, and sometimes the other ])arts of the wings as well, 

 rivuhms browu lines or strigic are visible. Transverse anterior line of 

 the pale ground color, followed by a line of the brown shade, very 

 strongly bent outwardly, with long acutci outward teeth on tlie median 

 vein and in tin? submedian interspace. Transverse posterior line brown, 

 often mai'ked only by the contrast between the median darker and tlie 

 subtermiual paler shades, in course slightly sinuate, tinely denticulate, 

 with an abrupt and usually long acute inward tooth on vein II. Subter- 

 miual line of the pale ground color, broad, continuous, somewliat <lif- 

 fuse, rather irregularly sinuate, ])receded by a brown shade which 

 darkens the outer half of the subtermiual space, and additionally 

 emphasized by a series of preceding black spots which sometimes 

 develo]) into a more ])rominent mark or shade op])osite the hind angle. 

 Apex pale, interiorly marked by a black oblique streak, which is out- 

 wardly dittuse and does not cross the subtermiual line. A series of 

 black terminal lunules, preceded by white scales. Fringes alternated 

 with yellow and brown. The median space in the female is brown 

 superiorly, usually also along the transverse posterior line, and some 

 times the entire lower part is also more (u- less marked with this same 

 color. Ordinary spots marked by gray raised scales, and connected 

 by a rather broad black line, Avhicli is distinct in all the females seen 

 by me, but tends to become obsolete in the males. A round dot of 

 black raised scales below the median vein in the median s])ace. Sec- 

 ondaries even, pale ocherous or yellowish white, with a brown terminal 

 line. Beneath, dull powdery, with ])roininent, broad, brown, extra- 

 median lines on all wings, an incomplete subtermiual line on primaries, 

 a discal spot on secondaries. 



Expanse of wings, 2S to .'>.'» mm. = 1.12 to 1,.'>L* inches.

This s])ecifs seems not uncommon locally. Dr. Behr's description is 

 of a most unsatisfactory character and would not have sufficed to dis- 

 tinguish the present si)ecies from //, modesia without the material in 

 the Hy. Edwards colIecti<ni, wiiich contained compared specimens. 



Besides the characters already enumerated this species is distin- 

 guished from both the preceding by the continuous subtermiual line. 

 and by the subapical black streak which does not cross this line. In 

 both these characters it agrees with H. modesta-^ than which it is 

 larger and with a dilferent ground color. The distinctive features will 

 be more fully given with the new sjx-cies. 



Hypena modesta, now s])ocins. 



Ground color luteous gray with bluish gray powdeiings, giving the 

 insect as a whole a pearly gray appearance. Head and thorax concol- 

 orous with the palest color of the primaries. Abdonu'U paler, of tlie
