Some Additional Bees from Prussian Amber.

wings rather pale reddish brown; stigma large but short; third trans- 
versocubital nervure with a strong double curve; basal nervure meet- 
ing trans versomedial; scape rather short (about 1020 q); third antennal 
joint longer than second; fourth very short, about twice as broad as 
long; fifth conspicuously longer than fourth (length of fourth 102 p); 
distance between antennae at base about 527 p ; distance from antenna. 
to eye 408 p ; hind basitarsus about twice as long as broad, thus longer 
than in the other species.

Second submarginal cell on marginal .... 204 
Upper section of basal nervure 425 
Lower section of basal nervure 1275 
Length of first discoidal cell 1870 
Length of first submarginal cell (obliquely) . 970

amber more than 1800 years ago. 
Electrapis (?) tornquisti sp. nov. 
Length about lU /2 or 12 mm; robust, Bombus- like; head and 
thorax with abundant erect plumose white hair; face with scanty 
fuscous hair; at one side of the thorax just above the right tegula, 
the hair is broadly tipped with dark fuscous; the long hair on the 
front and legs is also partly fuscous. The irregulär, unilateral arr an ge- 
ment of the luscous-tipped hairs at one side of the thorax suggests 
that either the hairs here have been stained in some way, or the white 
hairs have been bleached except at this point; either process is inex- 
plicable to me; the transition from the dark to the light is quite 
abrupt. Abdomen broad, apparently black, with the hind margins 
of the segments rather broadly white, like some Anthophora ; pubescence 
of abdomen short and pale; wings hyaline, nervures rather dark 
ferruginous (subcostal black); stigma practically obsolete; hind basi- 
tarsus more than twice as long as broad; fourth antennal joint con- 
spicuously shorter than fifth (length of fourth about 170 p, of fifth, 
272, of last joint, 510). 
Claws strongly bifid, the inner tooth falling about 119 p short 
of the outer; pulvillus large. Middle tibia with a single sharp spur;
