NO. 1376. LEPIDOPTERA OF THE KOOTEXAI DLSTRICT-DYAli. 8G3 



Stage Z— Head slightly bilobed, rounded, brown; cervical shield 

 brown. Body moderate, feet of joints 7 and 8 a little smaller, joint 12 

 scarcely enlarcred. White, the skin dark, spicular; tul)ercles small, 

 brown; mix pointed; feet and leg plates smoky; cliin gland clear, 

 conical. 



Stage 7Z— Head bilobed, oblique, brown, smoky sliadod, eye black; 

 width, 0.5 mm. Body with joints .5-6 and 12 slightly enlarged, feet 

 nearly equal. Pale whitish with faint brown shadings, not defined; 

 tubercles minute, dusky; seta> pale. 



Stage III. — Head ])ilobed, brown, dark dotted by the tubercles; 

 width, 0.8 mm. Body rather slender and tapering a little to the ends, 

 subequal. Translucent 3^ellowish sordid green from the food; dorsal, 

 subdorsal, lateral, and broad substiginatal lines whitish, sharply edged, 

 but obscure, a slight brown shading between them; tubercles small, 

 black. 



Stage lY. — Head pale luteous, darkl}^ reticulate, tubercles l)lack, a 

 black shade before vertex of lobe within; width, 1.2 mm. Body 

 moderate, equal, of a translucent reddish brown; dorsal line narrow, 

 whitish, a broad smoky area around tu))ercle i; subdorsal and lateral 

 lines whitish, not edged, the space between lateral and substigmatal 

 lines smok}' blackish on the edges, brown centrally. Substigmatal 

 band whitish, not contrasted; subventer faintl}^ brown tinged. Tul)er- 

 cles small, black, contrasted; cervical shield shining, concolorous with 

 the markings before, but luteous behind; feet pale. 



At this point the larvte became persistent in their efl'orts to hil)crnatc, 

 but a stage was obtained with head of 1.4 mm. on September 18, and 

 another of 1.7 mm. on October 7, ])ut they did not differ in markings 

 and are not improbably interpolated. The last stages remain to be 

 observed. 



HELIOPHILA ROSEOLA Smith. 



One hundred and thirty-four specimens, June 30, July 2. S, 19, 24. 

 27, 31, August 4, 5, 6. It varies in the depth of tlie reddish tint of 

 the fore wings, but this is never wholl\^ lacking. The transverse- 

 posterior line sometimes appears as a row of five dots, l)ut U\o is the 

 usual number, and they may be wholly wanting. The species ai)proaclies 

 calgarlana Smith. Some of the darkest forms apparently come out as 

 that species in Smith's synoptic table on account of the presence of a 

 faint darker shade under the median vein; but on eomparison with the 

 types of calgarlana the roseola arc all far less brightly marked and 

 can not l)e confused with it. It is closely allied to and perhaps 

 only a race oifarcta Grote, which lacks the red tint. The larva is like 

 farcta, with the markings brighter antl more contrasted. It fed on 

 grass. 



.£)/£/.— Laid crowded in the groove of a leaf, gummed into a mass.
