1. — E. luteus, n. s. 



Body uniformly livid brown ; legs paler ; wiugs whitish, almost 

 colourless, veins livid. 



Long, cum alis 2-2^ mill. ; exp. alar. 3^ mill. 



Cuba (Gundlach). I have seen but two examples, in bad condition, 

 gummed on paper. 



This genus is perhaps the most curious of all the Psocina ; it re- 

 sembles Termes in a certain degree, and still more the genus JEmhia ; 

 but it truly belongs to the Psocina, for the body is less elongated than 

 in Embia, and without appendices. 



Genus Emphebia, Hagen. 



Head flattened, triangular. Eyes large, somewhat prominent. 

 Ocelli placed close together. Antennae as long as the body, slender, 

 2.5-jointed, the two basal joints stoutest. Mouth as in Psocus. Pro- 

 thorax forming a narrow ring, free. "Wings flat in repose, scarcely 

 longer than the abdomen, oval, posterior margin somewhat contracted ; 

 veins very strong, ciliated. Superior wings with the sub-costa straight, 

 united to the costa before the apical third ; between them a fine ad- 

 ditional vein ; median vein forked in the middle shortly after emitting 

 a branch (3) widely forked towards the middle of the posterior margin ; 

 superior branch (1) and inferior ditto (2) giving off" a long fork towards 

 the apex, and also a simple branch ; the superior branch (1) towards 

 the anterior margin, the inferior (2) towards the posterior ; the sub- 

 costa is united at the end by a transverse vein with the simple branch 

 of the superior branch (1), thus forming a trapezoidal pterostigma. 

 Posterior ^vings with the reticulation of Amphientomum paradoxtim. 

 Abdomen oval. Legs moderate ; femora stouter ; tibiae cylindrical ; 

 tarsi with the first joint long, the two others equal, scarcely two-thirds 

 the length of the first. 



1. — E. reticulata, Hagen. 



Uniformly brown, as is almost always the case in amber insects. 

 The individuals appear to be males, judging from the bifid part at the 

 apex of the abdomen. 



Long, cum alis 2 mill. ; exp. alar. 3 mill. 



Eossil in Prussian amber ; three examples, which are no longer in 

 my possession. Described and figured in Berendt'e " Organische Rcste 

 iui Bernstein," T. ii., p. 64, tab. 8, fig. 6.
