nal whitish line; immediately in front of the humeral suture a whi^sh line 
extending from its middle to the prothorax. Pleura whitish with a short black 
line above in the humeral suture and in each of the two sutures before and be¬ 
hind the spiracle, and a large black spot below in the segment before the spiracle 
which is black. The segment before the spiracle with a broad coppery-red stripe 
covering nearly its whole surface and touching the upoer ^ of the suture before 
the spiracle; the spiracle-bearing segment with a much narrower stripe, extend¬ 
ing from the spiracle, where it is pointed, nearly to the origin of the wings; and 
the segment behind the spiracle with a still narrower stripe slightly abbrevi¬ 
ated above and below. Antealar sinus generally dark-green, sometimes cop¬ 
pery-red. Sternum whitish. with a narrow, basal, whitish annulus, 
interrupted above, on joints 3—7, and occasionally with a faint dorsal whitish 
line on 2—4; its sides indistinctly whitish. On the terminal ^ of 10 is a carina, 
tipped with a minute slender thorn. Venter black, pale brown at base and tip. 
Superior abdominal appendages forcipate, about times as long as the 10th abdo¬ 
minal joint, regularly curved inwards but not at all downwards on their upper 
edge, obtuse at tip, and when viewed in profile expanded downwards in a reg¬ 
ular curve on their terminal blackish towards their tip, rather pale brown 
at their base, their exterior edge above except at the extreme base and tip with 
minute teeth directed obliquely backwards. On the middle of their inferior 
surface is a large laminiform tooth about l-5th as long as the appendage itself, 
with its sides nearly parallel and its tip obtusely convex, directed downwards 
and inwards and a little forwards; and behind that again is a small round 
tubercle, beneath which a narrow laminiform prolongation of the large lamini¬ 
form tooth sweeps round aud then extends, directed inwards and downwards, 
to the extreme tip of the appendage. On the upper surface of the appendage is 
a carina, curved inwards at its base where it terminates in a tubercle, and be¬ 
hind the large laminiform tooth turning inwards and then assuming a narrow 
laminate form and running with its edge parallel to that of the narrow prolon¬ 
gation of the laminiform tooth to the tip of the appendage, so that the two to¬ 
gether form a spoon-shaped cavity. Above, on the posterior base of the large 
laminiform tooth is a small indistinct tubercle. Inferior appendages just attain¬ 
ing the large laminiform tooth of the superiors, pale brown at base, blackish at 
tip, suddenly tapered near their base, thence cylindrical and terminating ob¬ 
tusely with a very robust short thorn or angle at their extreme tip directed 
inwards and upwards. blackish; coxae and trochanters whitish; femora 
“posteriorly” whitish on their basal 'i with a “posterior” longitudinal row of black¬ 
ish dots, and “posteriorly” at their extreme tips whitish immaculate, the in¬ 
tervening space blackish; tibiae “superiorly” whitish except at tip. Wings 
hyaline; front wings with a carmine-red basal spot extending along the post- 
costal margin beyond the point opposite the tip of the quadrilateral, thence 
curving round the tip of the quadrilateral with an evanescent outline at a dis¬ 
tance of 4—6 cellules from it to the median sector, thence following that sector 
to the arc, thence following the submedian vein to the base of the wing. Com¬ 
mencing at the base of the wing 1—6 of the first series of antecubitals, and 
5—11 of the second series, and also 1—6 of the areolets of the basal area, are
