pterothorax, and abdomen are especially clear, but the prothorax 
and head are not preserved. The wings on one side, although lacking 
the apical portions, are very clearly preserved; those on the other 
side are twisted and folded together. Widely spaced pits in the 
impressions of the veins and cross veins indicate the original 
presence of trichia or small setae. The segmentation of the abdomen 
is especially clear and the lateral extensions of the segments, 
mentioned above in the type, are faintly preserved in the obverse 
half of the fossil. Also, in that counterpart, which shows the ventral 
view of the abdomen, the bases of the ovipositor valves can be seen 
in the 8th and 9th segments. The ovipositor appears to be about 5 
mm long before disappearing at the edge of the concretion. The 
cerci are not preserved. The following are the dimensions of this 
fossil: fore wing (as preserved), 15 mm; width, uncertain; hind wing, 
length (as preserved), 15 mm; width, 6 mm. Body, length (from front 
of mesothorax to end of abdomen), 25 mm; pterothorax, length, 5 
mm; width, 4.8 mm; abdomen, length, 18.5 mm; width, maximum, 
4.6 mm. 
3. No. HTP 415, Helen and Ted Piecko collection. This is a 
poorly preserved specimen, resting in the same position as the 
previous one. The venation is clear enough for identification of the 
species, and the prothorax and even the head, which is not shown in 
other specimens, are discernible. Neither the ovipositor nor the cerci 
are visible. The dimensions of this specimen are as follows: fore 
wing (as preserved), 20 mm; width, uncertain; dimensions of hind 
wing uncertain. Body length (from front of mesothorax to end of 
abdomen), 25 mm; pterothorax, length, 6 mm; width, maximum, 4 
mm; abdomen, length, 20 mm; maximum width, 4.5 mm; pro- 
thorax, length, 3.3 mm; posterior width, 2.5 mm; anterior width, 1.5 
mm; head, length, 3 mm; width 3 mm. The head as preserved shows 
somewhat protuberant eyes; the head is obviously seen in dorsal 
view, with no indication of the beak. 
Discussion of Structure 
The wings of calopteryx, as far as they are known at present, are 
shown in figure 2, which is based mainly on specimen HTP 12523, 
with some details added from the other specimens. The figure shows 
more of the basal parts of both wings than was known to Hand- 
lirsch. The homologies of the veins are obvious, the convexities and 
concavities being clearly preserved. Handlirsch (191 1) confused MA
