4. Descriptions of new Species of Zygsenidse and Arctiidae. 

 By Herbert Druce, F.L.S., F.Z.S., &c. 



[Received April 30, 1883.] 



(Plates XXXIX. & XL.) 



The following descriptions are all taken from specimens in my 

 own collection, mostly collected in Ecuador by Mr. C. Buckley, to 

 which are added a few others that I have found undescribed in 

 working through this group of the Heterocera for the purpose of 

 making out the Central-American species for the ' Biologia.' Many 

 of the species of Zygsenidee are the most wonderful of all the Moths ; 

 in some cases they so closely resemble Hymenoptera, that at first 

 sight it is almost impossible to determine to which order they belong. 

 In the present paper I have described fifty new species, representing 

 twenty-four genera. 



Fam. Zyg^nid^. 

 EuPYRA, Herrich-Schaffer. 



EuPYRA herodes, n. sp. (Plate XXXIX. fig. 1.) 



Wings uniform greenish black, slightly metallic along the costal 

 margin of the primaries, a large hyaline patch crossed by the black 

 veins close to the apex : head and thorax black ; abdomen greenish ; 

 antennae black, tipped with white ; legs black ; tarsi white. 



Expanse Ij inch. 



Hab. Ecuador, Sarayacu (Buckley). 



This peculiar species is very unlike any other that I am ac- 

 quainted with, and may at some future time prove to be a new 

 genus ; but as I have only seen a single specimen, I think for the 

 present it is better placed in the genus Eupyra. 



Eupyra salmoni, n. sp. 



Primaries brownish black, thickly speckled with bright metallic 

 green scales ; four round hyaline spots, the first pair within the 

 discoidal area, the second beyond and nearer the apex : secondaries 

 black, with two elongated hyaline spots close to the base, and a 

 round one beyond nearer the outer margin : bead and thorax black ; 

 abdomen green, with a central black line ; a white spot on the crown 

 of the thorax, and one on each side of the abdomen close to the 

 base ; underside of abdomen white ; legs white; tarsi black ; antennae 

 black, slightly whitish at the tips. 



Expanse 2 inches. 



Hab. Colombia, Antioqua, Frontino (Salmon). 



Eupyra cephalena, n. sp. (Plate XXXIX. fig. 2.) 



Wings black ; primaries thickly powdered with bright green scales, 

 a band of hyaline spots close (o the apex, a small spot at the end of
