Descriptions of Hymenoptera from Baltic Amber. 
D 
Vespidae. 
JPalaeovespa Cockerell. 
This genus was based on three species from the Miocene of 
Florissant, Colorado. 
JPalaeovespa baltica sp. nov. 
5. Length about 16 mm, or perhaps a little less; head and 
thorax 6 mm; anterior wing about 11 mm; abdomen broad at base, 
and witli the apical part of the segments ferruginous; venter ferru- 
ginous, darkened apically; sting visible; 
legs dark ferruginous or fuscoferruginous ; 
wings dark rufofuliginous , first sub- 
marginal cell longer than the other two 
together; third submarginal much broad er 
than second above, the two sides of the 
second concave, as in Vespa occidentalis. 
The structure of the legs seems entirely 
as in modern Vespa, with very long hind 
basitarsus, bearing short hair on its inner 
side; middle tibiae with two apical spurs; claws simple, with a strong 
basal bristle, exactly as in Vespa. 
Fig. 3. Palaeovespa baltica Ckll. 
Second submarginal cell. 
Head with long fuscous hair, as in modern Vespa ; eyes normal 
for Vespa, apparently; the markings of head, thorax etc., cannot be seen; 
Antennae normal for Vespa ; flagellum black, thick, not curled at 
end; third antennal joint long, exactly as in V. occidentalis. 
Marginal cell pointed, as in Palaeovespa, and also the modern 
Vespa occidentalis. 
Apex of first discoidal cell oblique, as in Palaeovespa ; it is not 
oblique in V. occidentalis. 
Recurrent nervures joining second submarginal cell far apart 
(subequally distant from base and apex); in V. occidentalis they are far 
apart, but the second joins the cell near the middle. 
Base of second submarginal cell scarcely deflected or bent to 
first recurrent nervure; in Vespa it is strongly bent.
