Carpenter — Amber Mecoptera

of M; no anal cross-vein. Male genitalia as in figure 4B; 
the copulobi (cl) with deeply incised margins dorsally, 
forming a posterior lobe; paraprocts (pr) large; spiral 
filament (sf) forming only part of a single loop, much 
as in apicalis. 
Figure 3. A, Fore wing of Bittacus jossilis, n. sp. (liolotype) ; B, fore 
wing of Bittacus succinus, n. sp. (holotype). 
There are four amber specimens which I am identifying 
as this insect: No. 5117, a complete male (fore wing, 15.5 
mm. long), with virtually all body structures preserved, 
including genitalia; No. 5118, a female (fore wing, 15 mm. 
long), complete except for one pair of wings; No. 5111, a 
female (fore wing, 16 mm. long), complete except for one 
pair of wings. 
I am convinced that this is the species of which Hagen 
had four specimens (females) and which he discussed 
under the name of Bittacus antiquus Pictet. The latter was 
first technically described by Pictet in 1854 (p. 379; pi. 
40, fig. 26) from a single, poorly preserved specimen. 
Hagen reproduced Pictet’s original figure and added one 
of his own (pi. 8, fig. 22). The most notable aspect of 
Pictet’s drawing is the very short beak (much like that 
of Panorpodes) ; it was this characteristic that induced 
me to establish the genus Electrobittacus for antiquus in 
1931. Hagen expressed doubt about Pictet’s representa- 
tion of the head, but did not state what his specimens 
showed in this respect. Significant, also, is Pictet’s draw-
