PLATE XVIII 



Fig. I. AcRONYCTA METRA Sm. Silvertoii, Colo. (July i6th). £. 



This and fig. 14 represent a pair taken by ourselves in nji 1 at an alti- 

 tude of g.ooo ft. It is probably Smith's species. 



2. Lasyonycta (.-^narta) subfuscula Grt. Silverton, Colo. $. 



This agrees so well with Hampson's figure of Grote's type that we feel 

 fairly sure of our reference. We would call attention to the fact that in the 

 $ , which has apparently been unknown heretofore, the antennae are bipcctinate 

 to near tip. Fig. 8 is the $ of this species. 



3. Lasiestra (ScoTor,RAMMA)iNFUScATA Sm. Silverton, Colo. 9. 



We captured two fresh 9 9 of this species at an altitude of about 

 12,000 ft. 



4. Anarta melanopa Thun. Silverton, Colo. S. 



We took a long series of both se.\es of this species during the latter part 

 of July and first week of August. It appears to be rather variable in the dis- 

 tinctness of the maculation of primaries, especially in the 9 sex. 



5. Heliothis villosa Grt. Silverton, Colo. (July 8-15). S- 



6. Heliothis villosa Grt. Silverton, Colo. (July 8-15). 9. 



This species was quite common about the middle of July and we took 

 a series of about 70 of both se.xes in prime condition. In color the primaries 

 are very constant, being an olive brown with no trace of reddish powde.ing; 

 the main point of variation is in the width and distinctness of the median light 

 band. The yellow spots of secondaries are variable and in one $ specimen the 

 secondaries are uniform black. This approaches very close to sexata Sm. 



7. Heliothis honesta Grt. Mt. Ranier, Wash. (July 16-23). 9- 



We have other specimens from the Lake Tahoe region Calif, but in 

 both localities it was rare. 



8. Lasyonycta subfuscula Grt. Silverton, Colo. 9 . 

 Compare with fig. 2. 



9. Alypia mac-cullochii Kirby. Silverton, Colo. (Aug. 1-7). 9. 

 Apparently referable to this species ; fresh specimens have the banding 



distinctly yellowish ; in worn ones it tends to become white ; the $ shows traces 

 of yellow scaling along the costa between base and discal dot. 



10. Parasemia plantaginis var. hospita Schiff. Silverton, Colo. $ . 



11. Heliothis subatra Sm. Mt. Ranier, Wash. (July 24). $. 



12. Heliothis subatra Sm. Mt. Ranier, Wash. (July 24). 9. 



We took a long series of this species in Paradise Valley, Mt. Ranier, 

 where is was quite abundant ; it is closely related to villosa Grt. from which it 

 differs in the greater e.xtent of the pale yellow areas, especially noticeable be- 

 yond the reniforni. 



13. Heliothis persimilis Grt. Silverton, Colo. (."^ug. 8-15). 9. 

 •Agrees exactly with Grote's figure and description. We see no reason 



why this should be united with villosa Grt., which in our long series shows no 

 trace of red scaling nor cellular yellow dash. Our Silverton specimens were
