1. c. : »The single imperfect specimen so far found in Amei'ican deposits — the only one indeed 

 in any rock formation — proves to belong to a distinct generic type, remarkable for the wide Separation 

 of the ocelh. 



Paropsocus (Ttägog, Psocus). The single insect on which this new generic group is based is very 

 fragmentary, but seems to difFer so clearly from other types of Psocina, wliether living or fossil, that 

 it can be recognized as distinct. The head is broad, not including the eyes as broad as long, the nasus 

 promiment, verj' broadly convex, almost truncate; the eyes are very large, very promiment, globose, 

 subpediceUate, being, stronglv constricted at base, widening the head one-half ; ocelli large, exceptionally 

 distant, the outer paired ocelli infringing on the margin of the eyes. Antennae with the first, second, 

 and third joints successivelly narrower by one-fourth, the first and second broader than long, not large, 

 the third Joint four or five times as long as broad, cylindrical, the remaining joints on the proximal 

 •third of the antennae two or three times as long as broad, smallest at base, apically rounded. Prothorax 

 narrow, pedunculate, free, with its angulate apex overlapping the mesonotum, longer than broad. Meso- 

 thorax much broader than the total [pag. 118] widh of the head. Fore tibiae slender, longer than and 

 not half so stout as the fore femora. Abdomen very short and stout, tapering very rapidly behind. 



i-*erhaps this genus in as nearly related to Amfliientomiim as to any other. A single species is 

 at hand.« 



Paropsocus disjunctus Scudd. 1890. 

 Paropsocus disjunctus Scuddee, Tert. Insect. 1890, p. 118, Taf. 5, Fig. 51. 



Nordamerika, White River in Colorado (Oligocän). 



1. c. : »The single specimen unfortunately shows only an insignificant fraction of neuration, and therein 

 no distinctive parts, but only those which are common to all genera of Psocidae. So far as can be seen, 

 the head, thorax, antennae, and legs are absolutely naked. The plate wrongly shows the left antenna 

 as the tarsus of the fore leg. The third Joint of the antennae is shorter than the width of the head 

 between the ej^es. 



Length of body 1,6 mm; breadth of head 0,45 mm; of thorax 0,75 mm; length of third antennal 

 Joint 0,3 mm. Fossil Canon, White River, Utah. One specimen, Nr. 33 e, W. Denton.« 



Die Abbildung zeigt nicht mehr als die Beschreibung, eher weniger. Die beiden verdickten 

 Basalglieder, die Geißelgheder , die Ocellenstellung , die Größe der Augen, die Körperform lassen er- 

 kennen, daß es wirklich eine Copeognathe ist. Über die Stellung läßt sich nur auf Grund der weit 

 voneinander entfernten hinteren Ocellen, die den Augenrand berühren, und auf Grund des großen, von 

 oben sichtbaren Prothorax sagen , daß sie zu der Unterordnung Heterotecnomera * gehört , und zwar in 

 die Gruppe Deloderata^. Sie gehört also sicher nicht zu den Amphientomiden. Eine weitere Fixierung
