124 THE ENTOMOLOGIST. 
pale yellow, and was thickly covered with white powder 
along the posterior margin ; as usual, the eyes were inserted 
in round black spots (see fig. 2). The claws of the anterior 
legs were brown. 
After the larve had moulted for the last time the white 
powder had entirely disappeared. The head now assumed a 
shining, ochre-brown tint, with black spots, in which were 
the eyes (figs. 3, 4); the body was of a pale, feuille-morte 
colour, and wrinkled, the skin being in folds as before. They 
descended into the ground for the purpose of passing into the 
pupa state; but as on the occasion of making these observa- 
tions I only had one or two examples at a time, and I am 
convinced that any disturbance of the mould prevents the 
completion of the metamorphosis, [ let them remain quietly. 
Thanks to which, it may be, the imagos appeared; but in 
consequence of which I missed the opportunity of observing 
the pupa, 
The perfect insects weré produced at the beginning of

3rd and the 14th of that month. Having regard to the length 
of the body, and more especially to the neuration of the 
wings, they certainly belong to the genus Emphytus; the 
structure of the antennz, however, approaches more nearly 
to that of Nematus, while the habit of the larva closely agrees 
with that of many species of Selandria. The head is quadrate, 
with rounded angles (looked at from above), black, and 
thickly clothed with very short hairs; the sides of the head, 
behind the eyes, are very projecting, and the vertex has a 
number of elevated points. ‘The labrum is very hairy; the 
_ mandibles are short and broad; the palpi are rather long, the 
middle joints being of a whitish tint. The thorax is clothed 
with a short pubescence; the tegule are brown, and the 
cenchri clear white. The first abdominal segment is black, 
and deeply notched on the posterior margin, so that, as is the 
case with the males of Cimbex, a considerable triangular 
space remains open, within which a white membrane is seen. 
The rest of the abdomen is shining and orange-yellow, both 
on the dorsal and ventral surfaces. The valves of the 
ovipositor are dark brown, nearly black. The antenne are 
black, and are longer than is generally the case in the genus 
Emphytus. Wings transparent, iridescent, a little darker at
