BESCIVA LONGITUDINELLA, new species. 



Second joint of labial palpi white, barred exteriorly with light 

 brown; terminal joint white \vith two indistinct brown anniilations. 

 Antennae light brown with wliite annulations. Face, head, and thorax 

 white laterally with a light brown central streak. Fore ^vings with 

 the white ground color strongly overlaid by light ochreous browai and 

 black scales; a nearly continuous, longitudinal, undulating line runs 

 through the middle of the ^ving from base to apex, bordered above 

 Avith pure wliite; another black longitudinal line covers basal four- 

 fifths of the fold ; the rest of the wing area is ochreous brown, with the 

 costal edge slightly dusted with black. Hind wings blackish fuscous 

 with ochreous cilia. Abdomen blackish above, light ochreous on the 

 under side. Legs whitish ochreous, dusted exteriorly with brown. 



Alar expanse. — 9 mm. 



Habitat. — La Chorrera and Trinidad River, Panama, March, April.

GALTICA, new genus. 



Type. — Galtica venosa, new species. 



Labial palpi long, sickle-formed, reaching far beyond vertex; sec- 

 ond joint slightly thickened with apj^ressed scales; terminal joint 

 nearly as long as second, slender, acute. Fore wings elongate ovate ; 

 apex bluntly pointed ; termen rounded ; 1 1 veins ; 7 and 8 coincident ; 

 4 and 5 shortstalked from the end of the cell; 2 and 3 widely separate 

 from before the end of the cell; transvei-se vein nearly obsolete; 

 16 furcate at base. Hind wings wider than the forewdngs; costa 

 nearly straight, slightly deflected beyond the middle; apex bluntly 

 pointed; termen and dorsum rounded; 8 veins; 6 and 7 separate, 

 though approximate; 3 and 4 connate; 5 cubital. Posterior tibiae 

 with heavy spreading tufts of long bristly hairs above. 



This genus comes nearest to Diadytica Walsingham, from which it 

 differs in having veins 4 and 5 of the fore wing shortstalked and in 

 having 3 and 4 of the hind wings connate, not shortstalked; more 

 strikingly distinguished in the ver}'- remarkable hair development of 

 the posterior tibiae; those of Diadytica being nearly smooth, 



GALTICA VENOSA, new species. 



Labial palpi straw-yellow, with a thm, longitudinal, anterior, deep 

 black line from base to apex, somewhat broader on the terminal 

 joint. Face, head, and thorax purplish black, mottled with a few 

 yellow scales. Forewings deep dull black with a broad, ill-defuied, 

 yellow band across the wing near base and with all the veins on the 

 outer half of the wing indicated by narrow, yellow lines ; an irregular 

 aggregation of yellow scales at tornus; cilia blackish with a yellow^ 

 base line. Hindwings dark fuscous. Abdomen blackish fuscous.
