Figure 6. Euhleptus cianielsi. Photograph of specimen YPMI8 (holotype of Athy- 
mudictya parva Handlirsch. Dorsal view (reverse); pr, pronotal lobes, maximum 
width of left fore wing in photograph, 4 mm. 
the one specimen preserved in lateral view (PE22016, figures 4 and 
5) the head is clearly hypognathous. The antennae are extraordinar- 
ily long and thin (PH 15, Wolff 229; Bandringa specimen 66- 
PBSM); for most of its length it is .04 mm in diameter and the 
segments are about .1 mm long. The antennae of PH 15 include 
about 1 10 segments and are almost certainly complete. The beak, as 
preserved in lateral view in PE22016 is 3 mm long and slender; 
several stylets project from its end. In specimen Damrow 236, the 
beak is 2.8 mm long and as seen in front view (figure 4) is triangular 
in shape, relatively broad basally, and bears long striae, as has been 
noted in other species of Palaeodictyoptera (Kukalova, 1970). The 
eyes are large and bulging, as shown in PH 15, Wolff 229, Bandringa 
specimen 66-PBSM, and especially in PE22016, in which the eye, in 
lateral view, is preserved in strong relief. 
Thorax. The prothorax is very small and, as Handlirsch showed 
in his drawing of parva, bears small lateral lobes about 1 mm wide 
(YPM18); the folded and twisted condition of the lobes in some 
specimens suggests that they were thin and weak. The legs ae known
