1. — A. jyaradoxum, Victct. 



Long. 4^ millimetres ; exp. alar. 8 mill. 



Fossil in Prussian amber. Described and figured in Berendt's 

 " Organisclie Reste im Bernstein," T. ii., pp. Gl-G-l, tab. 7, fig. 21, and 

 tab. 8, fig. 10. The insect is no Jonger in my possession, and I cannot 

 say whether my description (otherwise greatly detailed) is correct in 

 some points ; but I think that tlie species goes well with the following. 



The reticulation of the following species is arranged thus — 

 Sujyerior xoings. Sub-costa simple, slightly curved ; median vein 

 furcated in the middle, after having given off" a branch (3) on the in- 

 ferior margin, ending in a fork ; superior branch (1) united by a trans- 

 verse vein to the sub- costa, ending in a simple elongated fork ; inferior 

 branch (2) ending in a similar fork, after giving oflf a simple posterior 

 branch. 



Inferior loings. Sub-costa rudimentary ; median vein furcated in 

 the middle, after giving off a branch (3) to the posterior margin ; su- 

 perior branch (1) emitting a transverse vein to the anterior margin ; 

 inferior branch (2) simple. 



2. — A. incultum, n. s. 



Head and paljji black ; ocelli very distant, the posterior close to 

 the eyes ; antennae brown, slender, about 15-jointed, one-half shorter 

 than the wings ; thorax and inferior wings covered with blackish-brown 

 and silver scales intermixed ; inferior wings hyaline, greyish ; legs dull 

 yellow, the upper-side of the femora, the base and a broad band before 

 the apex of the tibia?, and the base of the first tarsal joint, black. 



Long. 3| mill. ; exp. alar. 7 mill. 



In gum copal (A.nime) ; probably from Zanzibar. I am acquainted 

 with only one individual, probably a female.

 A. ceglonicum, Nietner in lift. 



Head reddish-yellow, near the eyes, and on each side of the occi- 

 pital suture darker, brownish ; ocelli close together, the 'superior placed 

 in a black point ; palpi pale yellow, the two apical joints brown ; an- 

 tennae shorter than the wings, blackish-brown, the base, as flir as the 

 fourth joint, paler ; thorax blackish-brown ; superior wings clothed with 

 black scales, intermingled with silvery and golden ; paler spots near the 

 apex, two quadrangiJar silvery spots on the anterior margin near the 

 apex, one spot opposite on the posterior margin ; legs pale yellow, the 

 tibife at tlio knees and before the apex, as also the basal half of the first
