A FURTHER NOTE ON THE SLOTH MOTH. 1 



By HARRISON G. DYAR. 



Since presenting the description of Cryptoses choloepi, the 

 moth breeding in the hair of the sloth, two additional speci- 

 mens were noted among the material recently collected by Mr. 

 Wm. Schaus. This material is being held for Mr. Schaus 

 to study when he returns from collecting, but in the present 

 instance I take the liberty of noticing these specimens in order 

 to present a description of the markings of the adult, which 

 were entirely illegible in the original specimens. 



Fore wing long and narrow, the apex produced, but pointed; dark 

 bronzy brown, marked with longitudinal rays of shining pale ocherous, 

 as follows : Costa and internal margin, a broad stripe from the middle 

 of the cell to near the outer margin; a similar stripe on submedian 

 fold from base to margin, not discoloring the fringe; short, obscure 

 stripes between veins 2-3, 3-4, 4-5, and 7-8, the last stripe the 

 longest. Hind wing uniformly dark gray, the scaling somewhat thin 

 and semitransparent. Body parts clothed with short, shining, dark 

 gray-brown, hairy vestiture. Antennae of the male simple, smooth; 

 palpi porrect, down-curved, closely and minutely scaled; legs with 

 minute short vestiture of the same shining gray-brown color. Ex- 

 panse, 17-18 mm. 



Two males, one marked " Tuis, Costa Rica, 2400 ft., July, 

 1907 " ; the other, " parasite on sloth." 



After having learned the appearance of fresh specimens, 

 I discovered two such among Mr. Busck's material, captured 

 at light at Tabernilla, Panama. 



Sir George Hampson kindly informs me that I have over- 

 looked a recent description of a sloth moth, Bradipodicola
