male is placed between the process and the thoracic surface in such a way that 
the concavity on the inner margin of the appendage (see Tab. V. fig. 47) fits around 
the process. If these views be correct, the process in the female of P. cupida presents 
a less complex stage of development than in P. peramans.

3. The following details are not mentioned by de Selys, whose description’ was based on a unique male: 
labium pale, almost white; black mid-dorsal thoracie stripe covering more than the carina, its width 
being about one-half that of either antehumeral orange area; the black band “sur le premier espace 
latéral” (¢. e. mesepimeron) touches the humeral, net the median, suture below; second lateral suture 
with a black stripe on more than the upper half of its length; cuneiform orange spot on dorsum of 3 
reaching almost to the apex ; 8-10 black, not “plus pales.” The appendages of the type were “en 
mauvais état,” which may account for the differences I find in these; superiors straight, thick, rather 
obtuse at the tip, which is mot recurved towards the other appendages, an inner basal tubercle, and a 
larger pale inferior tubercle. Inferior appendages subequal, slender, with a superior anteapical tooth. 
Wings with the arculus distinctly (76-6 °/, front wings, 93°/, hind) or slightly beyond the second antecubital, 
its limbs subequal or the lower slightly the longer ; nodal sector arising near the fifth postcubital on the 
front wings, nearest the fourth on the hind ; ultra-nodal sector beginning 2-4 cells proximal to the inner 
brace-vein of the pterostigma on the frent wings, 1-3 on the hind; postcubitals, front wings 10-11, 
hind wings 8-9.

é. Dark metallic green, with the following markings: anterior edge of labrum, gene, mandibles, labium, 
some marks on the rear of the head, thoracie sterna, tibie and tarsi, pale yellow or almost white; hind 
edge of mesepimera, metapleura (except for a black stripe on the upper half of the second lateral thoracic 
suture [Balsas ¢], or on the whole length thereof, in the latter case sending off a branch on to the 
mesepimeron [Iguala 3 ]), femora, dorsum of abdominal segment 2 (except for an obscure transverse 
anteapical stripe), a transverse apical line on 1, a narrow transverse basal ring on 3-7, a narrow 
transverse apical ring (which may be interrupted mid-dorsally) on 9 and 10, and much of the ventral 
surfaces of 1-4, deeper yellow ; the greater part of the labrum (whose lateral edges are black) and of the 
nasus (which has two small spots and a transverse basal line black—these three may be united), a 
transverse row, anteriorly convex, of six spots on the frons just behind the base of the antenne (the two 
middle spots may fade gradually into the yellow of the gene, the spot directly behind each antenna 
may be divided into two closely approximated spots), a line along each eye-margin of the vertex, 
confluent anteriorly with the outermost of the six spots and posteriorly with a yellow spot on the rear 
of the head, a pair of occipital spots, a stripe on each side and the inferior margins of the prothorax, a 
transverse line on the anterior lobe in one (Balsas) male, a small twin-spot on the middle lobe, a still 
smaller twin-spot on the posterior lobe of the prothorax, the mid-dorsal thoracic carina, a humeral stripe 
divided by the humeral suture as usual (see footnote, p. 141) and a small superior mesepisternal spot. 
(Iguala ¢ ), or this spot united with an upward prolongation of inner (mesepisternal) part of the humeral 
stripe, thus forming a double, or longitudinally divided, humeral stripe (Balsas ¢ ), orange-red. 
Hind margin of prothorax convex, entire. No lamina behind the mesostigma. Superior abdominal appendages 
about as long as segment 10, yellowish, with black margins, straight, obtuse, having at their middle a very
