316 THE ENTOMOLOGIST. 
men with fine hair, and broad at base, not at all like the 
specimen of A. titania; hind tibia 83 mm., hind basitarsus 
about 24 mm.; hind basitarsus broadened; venation cannot be 
made out. The generic position of this specimen must remain 
wholly obscure. 
A. longeva was based on two specimens, which, judging from 
Heer’s figures, are probably not even congeneric. The specimen 
above described is from Ciningen, but Heer’s first one, from 
Radoboj, must be considered the true type. 
“* Osmia.”’ 
In 1849 Heer published Osmia antiqua from (Hningen. This 
was a poorly preserved insect, which cannot apparently be re- 
ferred to Osmia or any other genus with certainty. In Heer’s 
work, translated and edited by Heywood, ‘The Primeval World 
of Switzerland’ (1876), vol. ii. p. 48, I find a statement that 
there were three species of Osmia at CHningen. In the collection 
at Zurich I find three species from that locality, bearing manu- 
script names by Heer. One of these, an insect about 9} mm. 
long, the abdomen almost 6 mm., shows no venation, and is 
worthless for descriptive purposes. One is a wasp. The third 
may be described as follows :— 
vV Andrena (7) primeva, n. sp. 2. 
Osmia primeva, Heer, MS. A medium-sized species, with broad 
subglobose abdomen, clearly a bee. Thorax small; hind legs pre- 
served, showing scopa; three submarginal cells. 
The hind legs are robust, formed as in Andrena, except that the 
broad hind femur is swollen above at base ; this condition is, how- 
ever, distinctly approached in some species of Andrena. The tibia 
and broad basitarsus, the latter showing much long hair along its 
hind margin, are exactly as in Andrena. The middle basitarsus is a 
little longer than the small tibia, and is quite broad, narrowing some- 
what toward the base. The form of this basitarsus is rather unusual, 
but finds a close parallel in A. hattorfiana (Fabr.). 
The venation, so far as visible, is as follows: stigma long and 
well-developed, quite normal for Andrena: marginal cell quite normal, 
the apex narrowly rounded, just away from costa, as in A. morio ; 
second submarginal cell approximately square, receiving the first 
recurrent neryure about the middle, as in A. errans; third sub- 
marginal cell fully twice length of second, but about equally broad 
on marginal, receiving the second recurrent nervure just before 
the beginning of the last third; third transverso-cubital with a 
single curve, not at all angulate ; ‘second recurrent nervure normal 
in form. 
The relatively long third submarginal cell suggests Noma, but 
occurs also in Andrena, e.g. A. albicans. In the hind wing the 
marginal, cubital, and transverso-cubital nervures are visible, entirely 
as in Andrena. The transverso-cubital is a little oblique, the lower 
end most basad.
