118 Prof. Westwood’s Observations on the 
of the two insects which I had then but little doubt were 
the male Scleroderme; the antenne of these insects 
were described as ‘‘ 12-articulate,” and they are so repre- 
sented in Plate XV., fig. 12a. These two insects, de- 
scribed by me under the names of ‘“ Scleroderma ? 
fuscicornis”’ and ‘ Scleroderma? fulvicornis,’ are now 
ascertained not to be males of this genus; whilst the 
real males are now perfectly known, having been taken 
both by the late A. H. Haliday and Sir Sidney Saunders, 
the latter of whom communicated to me both sexes of a 
new species from Albania, which I figured in my ‘ The- 
saurus Entomologicus,’ Plate XXXI., fig. 138, male, 
fig. 14, female, where I gave a fresh generic synopsis in 
which the characters of the male are introduced. It is 
now evident that two at least of the small winged insects 
collected by Sir S. Saunders, referred to in the latter 
part of my monograph (p. 171), with 13-jointed antenne, 
large ocelli, and without any radial branch to the upper 
wings (having only the basal cells of the genus E:pyris), 
were male Scleroderme. 
The antenne of the male of Scleroderma cylindrica are 
represented in Plate LV., fig. 12, and those of S. ephippium, 
female, in Plate LV., fig. 6. They are 13-jointed in both 
sexes, those of the male being longer and more slender 
and filiform, and those of the female shorter, with the 
flagellum more clavate. ‘The mandibles are elongate- 
conical, terminated by three sharp teeth, which are not 
quite on the same plane, and the back of the mandible 
has a deep groove which reaches nearly to the large 
terminal tooth. The mandibles of S. ¢ phippium are 
represented in different points of view in Plate IV., 
figs. 1, 2,3 and 4. The lower parts of the mouth are 
small and weak, the maxille being scarcely larger than 
the labium and its parts. The maxillary palpi are 5- and 
the labial palpi 3-jomted (Plate IV., fig. 5, from S. ephip- 
pin). The legs are of moderate length, the anterior 
tibie with a small curved acute spur on ‘the inside of the 
extremity ; the tarsi 5-jointed, the basal joint in the fore 
leg with a semicircular incision on the inside, which 
is “brought into conjunction with the curved spur of the 
tibize (PL. IV., fig. 7). The tarsi are terminated by a 
rather large puly ‘illus and two strong but slender alte 
(fig. 8). The ovipositor of the female of S. ephippium 
and its various parts are represented in Pl. IV., figs. 
9,10 and 17. These consist of the normal component
