A New Genus of Atropidae. 



By Samuel E. Weber, Lancaster, Pa. 



The Atropidae were originally set apart from the Psocidae as pos- 

 sessing neither wings or ocelli, but in the three genera Psoquilla Hagen, 

 Doryptcryx Aaron, Psocinella Bangs (Psocatropos Ribaga) we find 

 in all of them one pair of rudimendary venated wings. To these I may 

 add a fifth genus with fully developed ocelli and possessing two pairs 

 of venated wings : we have then, as the generic term implies, an Atro- 

 pid with oCelli. 



CELL AT ARIA gen. nov. 



Fully developed ocelli. Head oblong. Emarginate on the 

 vertex. Clypeus small. Lips prominent. Eyes not prominent, 

 composed of small ocelli. Antennae filiform longer than body, 

 18 to 30 articulations beyond two stronger basilar joints. 

 Palpi four-jointed, the last joint tapered to a point at apex. 

 Maxillae tridentate, meso- and metathorax free. Two pairs 

 of rudimentary venated wings. Femora not dilated. Tibiae 

 half as thick as femora, and longer than femora. Tarsi three 

 jointed, the first joint longest, the second shortest. Claws 

 bidentate. Body very scantily clothed with hair. 



This genus differs from all the other Atropidae in that it 

 has not a prominent clypeus, and its head is more oblong than 

 that of other genera and is more prominent between the eyes, 

 and is emarginate on the vertex. The ocelli contrast this 

 genus most strikingly from other described Atropidae. A 

 further difference in structure is the two pairs of venated 

 wings found in Occllataria, which does not occur in any of the 

 other genera. 



Ocellataria gravinympha sp. nov. 



Length (6") 1-7-2 mm.; ($) 2.-2.3 mm. (Fig. I.)* 



The ground color of the body is of a faint yellowish-white covered 

 by a fine granular layer of bluish grey, most profuse on the ventral 

 surface of the abdomen and on the legs, which are darker than the 

 other parts of the body, with the exception of the borders and veins 

 of the wings, which, like the eyes, are black. The head appears lighter 

 in color than the other parts of the body; it is darker from the line

 of the economic importance of the Psocidae.
