Genus Thtlax, new genus. 



In some degree resembling Empheria, but differs as follows. The 

 ocelli are more sei^arated ; autenuje 40-joiuted, but shorter, and the two 

 basal joints stouter. Pro-thorax forming a transverse ring, slightly- 

 narrower than the head. Wings rather long, very narrow, lanceolate ; 

 the posterior margin appears angulated before the middle ; reticulation 

 analogous, but the median vein and the sub-costa are united by a trans- 

 verse vein before the pterostigma, so that there is an elongated hexagonal 

 areole below it ; the simple branch of the superior fork (1) broken at 

 the base, so as to form a short transverse vein from below. Inferior 

 wings much more acute, the anterior margin excised at the apex ; neu- 

 ration as in A. paradoxum. 



1. — T. Jlmhriatum, n. s. 



Uniformly pale brown ; very pubescent on the head, antennSB, 

 wings, and legs, the margin of the wings with long cilia. 



Long. 2^ mill. ; exp. alar. 4 mill. 



In gum copal (Anime) from Zanzibar. Thi'ee examples received 

 from Baron Osten-Sacken. 



The genera JEmpheria and Tliylax are somewhat allied to Ampliien- 

 tomum, but without scales. They have nothing in common with JEmhi- 

 dopsocus, save the free pro-thorax, which is not elsewhere found in 

 the Psocina.
