OF THE MALTESE ISLANDS. 0 
abdominal segments. Thorax with two tubercles on each side, the anterior one 
bearing two or three long slender spines. Abdominal segments each with one 
(possibly two) extremely minute tubercles at the apex of which is a minute 
broad flat spine; those on the 7th and 8th segments more conspicuous 
than the rest ; but all of these processes are so minute as to be easily overlooked. 
Wing-sheaths pointed apically and extending subventrally as far as the base of 
the 7th abdominal segment. Head distinctly elongated and somewhat triangular 
in outline ; in the empty pupa this often breaks away in the process of mounting 
when the outline may be seen to bear a striking resemblance to the head of an 
ox in miniature (Pl. I, fig. 13). Antennal sheaths distinctly segmented, lying 
curved behind the eyes and subsequently following the costa of the wing-sheath. 
Palpal sheaths originating near the centre of the frons, extending backwards and 
then curving suddenly forward so that the apex rests against the antennal sheath 
and lies pointing in the same direction. Legs extending slightly beyond the 
wing sheaths.
