250 THE ENTOMOLOGIST. 
fading into black, giving an appearance similar to polished 
tortoiseshell. Wings yellow at their insertion; radius pale 
as far as the stigma; the latter, together with nervures, dark 
gray; membrane of the wing iridescent. Abdomen brown- 
yellow, having on the dorsum six black transverse lines 
(basis of the segments), diminishing in thickness towards 
the anus. All the coxe black at the base, or with a black 
line towards the outer side; femora red-yellow; tibie 
yellow, the posterior pair being one-half blackish. Anterior 
tarsi having the ends of the joints brownish; posterior tarsi 
rather dark. 
The only male I possessed was black on the upper side, 
the ventral surface and the legs being yellow. The antenne 
were pretty robust, somewhat hairy, and entirely black. The 
head was black, with the exception of the trophi; and in 
these again the extreme points of the mandibles were black. 
The thorax was black, with the exception of the pronotum 
(yellow); scutellum black. The insertion of the wings was 
yellow; the principal nervures and the stigma deep brown. 
The dorsum of the abdomen was black, the margins of a 
brownish orange tint; the under side was also of this colour, 
but on the upper side the margins of the segments were 
yellowish. Legs yellow; the four anterior tarsi pale brown 
at the tips; the posterior coxe had a black smear at the 
base; the posterior tibie for one-half and the posterior tarsi 
sordid brown. 
It will be seen on comparison that there is a very great 
difference in the imagos between the present species and 
Klug’s Ventricosus. It may be said that in general this new 
species is much more darkly marked. 
As my insects died without having paired with the only 
male which I had succeeded in rearing, I requested Mr. 
Ritsema, who had got me the last examples from Haarlem, 
to see if he could send me some eggs. With a readiness for 
which I cannot sufficiently thank him he brought me a 
female from the same bushes, which female while in confine- 
ment had laid eggs on leaves of twigs placed in water. 
There was not the least doubt that the insect belonged to the 
same species. 
To my astonishment I observed that the eggs were not 
placed, as I supposed they would have been, in the nervures
