202 REVISION OP MAMESTRA SMITH. 



nary spots large, the s. t. line very distinct. The secondaries are dusky 

 and the thoracic tufts distiuct. The western specimens seen by me 

 have the ordinary spots contiueut, and to this form the name juncima- 

 cula was given by me, with an erroneous generic reference. 



Insolens is a moderate sized species with narrower and more pointed 

 wings, of a dirty pale luteous color and still paler maculation. The 

 s. t. line is preceded by a series of trigonate black spots, and the tho- 

 racic tufting is not distinct. 



Leucogramma is a small species, almost a miniature of insolens in 

 color, wing form, and style of markings. The median lines are narrow, 

 white, and even. 



Following these is a series of small, stumpy winged forms, not very 

 closely related to each other. 



Lepidula is a beautiful, bright red brown species, with a somewhat 

 contrasting, yellowish, reniform, and clean white secondaries. 



All the other similar forms have dusky secondaries. 



Determinata is a small, wood-brown species, with the median lines 

 distinct, black, and even, all the maculation well marked. 



Meditata is a deep, even, vinous brown, with blue powderings, all the 

 maculation faint, powdery, not easily traceable. The species is an 

 obscure one and readily recogaized, interfering with nothing else in the 

 series. The antenna? are serrate merely. 



Liistralis is a paler, carneous gray, larger than the preceding, and 

 better marked. The median and terminal spaces are more brownish, 

 and the fringes are somewhat unusually long. The male antennae are 

 shortly pectinated. 



Betracta is a broad- winged species, the primaries more ample than 

 in any other species in the series, and this, with the mottled fuscous 

 brown color, distinct median lines, and proiuinent black claviform, make 

 the species readily recognizable. The $ antennae are pectinated. 



Gnata is dark ash gray, with a prominent s. t. line, preceded by a 

 distinct yellowish white spot opposite the anal angle. The wing form 

 is more like the vicina series, which indeed the insect much resembles 

 in habitus, difiering in the serrate and "brush like" antennae. 



Occupying an isolated position in this series is distincia, a pale ash- 

 gray or whitish form, with narrow, subequal primaries, oblique slightly ' 

 dentate outer margin, and somewhat retreating niud angle. A distinct 

 black dash connects the transverse lines, crossing the median space. I 

 The species is not related to any other in this groupj but seems to have 

 affinities to latex and passu. 



Crotchii is out of place anywhere, but may be conveniently sand- 

 wiched in here, as it has a prominent W-mark in the s. t. line, allying it 

 with the following group. It is a robust species, sordid luteous to fus- 

 cous gray, the maculation sub obsolete, ordinary spots usually conflu- 

 ent, and claviform very large. In some specimens the s. t. line is indis- 

 tinct, and the isolating character somewhat obscured.
