only from a single fore leg in Wolff 229; the preserved part, appar- 
ently consisting of the femur, tibia, and tarsus, has a total length of 
3.5 mm; the tarsus appears to have five subequal segments. The 
wing venation, as previously noted, shows only a slight amount of 
variation among the 17 specimens examined. The shape of the wings 
is more diverse, but that has undoubtedly been determined to some 
extent by the process of preservation and the amount of movement 
of the sediment in which the specimens were entombed. The degree 
of variation in wing shape in the specimens of danielsi seems to be 
comparable with that reported by Kukalova-Peck (1971) for the 
Permian Dunbaria faseiipennis. The wing markings, consisting of 
four triangular spots along the anterior margins of both wings, are 
similar in both specimens in which they are preserved (PH 15 and 
PE32046). 
Abdomen. The segmentation of the abdomen is nearly homo- 
nomous, except for the 9th and 10th segments, which are slightly 
smaller than the others. The lateral margins of the tergites are 
extended posteriorly only slightly (YPM 18), about as in the Spilap- 
teridae. The ovipositor, preserved only in PE22016, is strongly 
curved and only 2.5 mm long, not extending beyond the end of the 
abdomen. The cerci (PE22016, and PE32036) are preserved to a 
maximum length of 10 mm, but since they end at the edge of the 
concretion, that is almost certainly not their full length. Segmenta- 
tion of the cerci is clear at intervals; the segments are .3 mm long 
(beyond the basal segments) and .3 mm wide, and covered with 
short hairs. The largest piece of a cercus includes about 34 segments. 
Relationships of Eubleptus 
Study of the new specimens of Eubleptus danielsi provides no 
evidence to justify the recognition of the order Eubleptidodea. On the 
contrary, all the evidence supports Handlirsch’s assignment of the 
family Eubleptidae to the Palaeodictyoptera. Furthermore, both the 
wing venation and the newly acquired knowledge of the body struc- 
ture of Eubleptus show a close relationship to the family Spilapter- 
idae of the Palaeodictyoptera. The wings of Eubleptus have the 
same general shape as those of the spilapterids, the hind wings 
being slightly broader than the fore wings. The only significant 
difference between the venational patterns of the two families is the 
reduction of CUA in the family Eubleptidae: it has only a small
