that the first segments are ringed with deep black, and often the 

 anal segments, while the intermediate are in shades of yellow and 

 fuscous. They also agree in the % genitalia, and in the S having 

 on the last segment beneath ten tufts, small, five on each side.

Texas. 



Mr. Ragonot's description is as follows: 



" Fore wings short, broad, costa rounded, blackish ; first line broad, dilated on 

 the inner margin, hoary gray, preceded by some dark red scales, which are 

 thickest on the inner margin. Second line narrower, less distinct, oblique, in- 

 dented on (liscal fold. Discal spots distinct, with a tendency to form a lunula, 

 followed by a gray cloud. Marginal spots distinct. Hind wings fuscous." 



This insect has, in some respects, much the appearance of S. nu- 

 biferella, and may be one with it, but it is much darker, and while 

 the markings very nearly correspond, I have no intergradations. 



5. S. semiobsciirella n. sp.— Labial palpi blackish gray ; front fuscous ; 

 antennae fuscous; thorax fuscous yellowish, shaded behind ; abdomen yellowish, 

 with a fuscous tinge dorsally. Fore wings arched on costa, narrow at base, broad 

 outwardly, angles distinct; basal field even light gray, slightly darker at costa; 

 middle and outer fields even dark gray; discal spots faint; lines indistinct, the 

 basal only evidenced in a broad blackish shading at edging of basal field and 

 gradually fading into the middle field ; outer line near margin augulated. Hind 

 wings yellow fuscous, edge fuscous. 



Central Texas. Taken in April and May. 



This species is catalogued by Mr. Ragonot under his name. I 

 have no knowledge that it has been described. I have a specimen 

 identified by him as the species, and describe it to give it a place in 

 this paper. 



6. S. subfuscella Rag., Diag. N. A. Phyc. p. 8, 1887.— Expands 22 mm. 

 Fore wings narrow, elongate, blackish gray, with a slight purple tint, inner 

 margin dark red at base. First line replaced by a broad, straight, slightly ob- 

 lique black band, externally blending into the ground color, and preceded by a 

 grayish band. Second line dark grayish, sinuous, edged with black. Discal 

 spots with a tendency to coalescing. 



This insect is described by Mr. Ragonot in his Diag. N. A. Phyc, 

 but no locality is given. As in that paper insects from the West
