NEW SPECIES OF THE GENUS STENOMA FROM 



COSTA RICA. 



[Lepidoptera; Stenomidce.] 

 BY AUGUST BUSCK. 



Stenoma liniella, new species. 



Labial palpi dark ochreous; second joint dark-shaded externally. Face 

 and head ochreous fuscous. Thorax ochreous fuscous with a deep black- 

 ish brown central longitudinal line. Forewings broad with evenly rather 

 strongly curved costa, bluntly pointed apex and straight termen and dor- 

 sum; light ochreus with three dark fuscous outwardly oblique cross-lines 

 as in Stenoma tristrigella Zellerand with a dark line around the entire 

 edge; the first and second cross-lines are nearly straight and parallel from 

 basal third and from the middle of costa respectively, and both curve 

 slightly outward, as they approach the dorsal edge; the third line, which 

 is nearer to the second than this is to the first, is bent outwardly in a 

 gentle curve and meets the second at the anal angle. Hindwings light 

 fuscous, darker towards the tip. Abdomen dark fuscous. Posterior 

 legs light ochreous. 



Alar expanse, 32-34 mm. 



Habitat: Sixola River, Costa Rica (Wm. Schaus"). 

 Type: No. 13202, U. S. National Museum; cotype in Brit- 

 ish Museum. 



Stenoma fraternella, new species. 



Labial palpi ashy gray with ochreous base. Head and thorax dark 

 fuscous. Forewings shaped as in Stenoma elegans Zeller, but hardly as 

 pronounced; dark brownish fuscous with a dusting of silvery scales and 

 three oblique dark-brown cross-lines; these are about equivalent and all 

 nearly parallel; one from basal third of costa, one from the middle, and 

 one from apical third, the last nearly straight across the tip of the wing, 

 the two others gently curved outward as they approach the dorsal edge, 

 which they do not quite reach. Hindwings dark fuscous. Both pairs 

 of wings on the underside with bright-yellow costal edges. Abdomen 

 dark fuscous above with reddish ochreous cross-bars; underside light 

 ochreous. Hind legs light ochreous; tarsal joints with tuft of hairs on 

 upper side in continuation of the tibial tuft. 



Alar expanse: 34-38 mm. 



Habitat: Juan Qinas, Costa Rica (Wm. Schaus). 



Type: No. 13203, U. S. National Museum; cotype in Brit- 

 ish Museum. 



This species would, on account of its peculiar wing- form 

 and of its tufted tarsi, fall in Zeller's genus Loxotoma, which, 

 however, as I have shown before, cannot be maintained as a 

 sound genus.
