together with the jaws, as also the eyes and ocelli during life, 
are shining black. The antenne (fig. 8) are slender, and 
consist of six joints: the first two basal joints are short, 
somewhat thick and compressed together, black; the third is 
a little longer than the three following together, somewhat 
curved, black, dark red at the tip; the fourth and fifth joints 
are red or reddish brown, both being dilated towards the 
apex; while the sixth—probably formed of the sixth to the 
ninth anchylosed, at all events showing the suture between 
the sixth and the seventh—forms a black pear-shaped knob. 
In one of the individuals I reared, the parts of the mouth seem 
somewhat turned up anteriorly. ‘The head is richly clothed 
with rather long black hairs, excepting below the cheeks, 
where yellow-gray hairs occur. The entire thorax, above and 
below, is covered with a similar thick gray fur. The abdo- 
men also has a similar clothing, only thinner and more 
woolly. The wings are tinted with orange, and have a narrow 
smoke-coloured border running inwards in each cell. The 
main trunks of the nervures are orange; the smaller 
divisions and terminations, brown. The stigma is very 
elliptical, and brownish black. The coxe, trochanters, and 
femora are shining black, but slightly punctured; the 
posterior femora not particularly thickened, and having 
merely a trace of a spinous projection. The tibiz are of a 
brownish orange colour; the tarsi somewhat less brown, or 
more yellow, both being covered with fine hairs of a golden 
yellow. The inner side of the anterior tibiz is completely 
covered with a close row of short bristly hairs of a golden 
colour. The claws are of a red-brown colour, and black at 
the tips. The pulvilli fuscous. 
In addition to the difference in the organs of generation, 
the females are only distinguished from the males in having 
the body coarser and larger; and, on the other hand, the 
jaws, together with the upper lip and the spine on the 
posterior femora, smaller. : 
Cimbex Lucorum appears to be not very common with us, 
examples being only occasionally observed. 1 remember, 
however, having observed a considerable number of these 
insects some years ago in a copse, near Voorschoten, flying 
after each other among the fresh green leaves of the birch 
trees; and | fancy that anyone passing the early spring in
