NO. 2050, LEPIDOPTERA OF THE PANAMA CANAL ZONE—DYAR. 263 



Possibly these should form a new genus, but as they do not differ 

 markedly from Leucochroma, and are led up to in markings by other 

 species,^ I leave them in this genus. They can not be placed in 

 Ischnurges, in which genus I originally described hicoloralis. 



LEUCOCHROMA EUPHARAMACIS, new species. 



Close to hicoloralis Dyar, the colors the same, the markings fuller 

 throughout, the white spaces reduced. Trace only of the brown 

 specks below the apex and at inception of the outer line; basal mark- 

 ings of fore wing confluent, marginal marks continuous. Expanse, 

 17 mm. 



Type.— Female, No. 16128 U.S.N.M., selected from a series of 17, 

 Trinidad River, March, 1912 (Busck). Other localities are Corozal, 

 Canal Zone, June, 1912 (Busck), July, 1912 (C. P. Crafts). 



Very close to hicoloralis Dyar, possibly a race of it. 



MARASMIA COCHRUSALIS Walker. 



40. Porto Bello, February, 1911 (Busck); Corozal, Canal Zone, 

 March, 1911, and May, 1912 (Busck), July, 1912 (J. Zetek, C. P. 

 Crafts) ; LaChorrera, April, 1912 (Busck) ; Trinidad River, June, 1912 



(Busck). 



SYNGAMIA ABNORMALIS Snellen. 



9. Trinidad River, March, 1912 (Busck); Cabima, May, 1911 

 (Busck) ; La Chorrera, May, 1912 (Busck) ; Corozal Canal Zone, July, 

 1912 (J. Zetek, C. P. Crafts). 



The specimens agree ^nth a female from Costa Rica labeled by Mr. 

 Schaus. In the male, there is a slight swelling on the costa between 

 end of first line and discal dot. 



SYNGAMIA SCIAGRAPHALIS, new species. 



Differs from ahnormalis (Snellen) Schaus in being tinged with 

 ocher, especially along inner margin, the costa of the male straight, 

 mthout swelling; lines of hind wing not quite as coarse and rigid 

 as in ahnormalis, the whitish bordering shades less contrasting. Ex- 

 panse, 15 mm. 



Type—Male, No. 16119, U.S.N.M.; Trinidad River, March, 1912 

 (Busck) . Also eight others, La Chorrera, May, 1912 (Busck) ; Corozal, 

 Canal Zone, July, 1912 (J. Zetek, C. P. Crafts), November, 1912 

 (C. P. Crafts). 



' Leucochroma meliusalis Walker has the pattern of coloration of these forms, which is still more nearly 

 approximated in— 

 LEUCOCHROMA ANALYTICA, new species. 



Similar to L. meliusalis, with which it was confused in the collection, but with the blackish scales almost 

 wholly removed. In meliusalis there are indistinct dark edgings to the stigmata and a dark terminal line, 

 which breaks into three distant dots below apex, derived from the corope type. In analytica, all the marks 

 are orange-yellow on a white ground, broadened, diffused, the terminal line also orange, except the 

 three minute dark dots below apex. Terminal line on hind wing a little darker than the other mark- 

 ings, but not dark as in meliusalis. Expanse, 19 mm. 



Cotypes.— Four specimens, No. 16127, U.S.N.M.; Trinidad, British West Indies (Schaus Gollection).
