together with the jaws, as also the eyes and ocelli during life, 

 are shining black. The antennae (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 coxae, 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 tibiae 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 tibiae 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 I fancy that anyone passing the early spring in
