PARAPHLEBIA.— PHILOGENIA. 61 
3. Nasus black, pale spot on either gena very small or connected by a pale band across the frons. Yellow 
lines on the thorax complete, except the humeral in aged males. Transverse basal ring on segments 3-7 
represented by a yellow spot on either side, no pale markings on 8-10, 9-10 pruinose above in old 
individuals. Superior appendages about as long as 9, of the general shape of those of P. zoe, except that 
they are curved throughout, instead of angulate at two-fifths their length; the basal end of the infero- 
internal ridge begins more gradually than in P. zoe. 
2. Nasus perhaps blue in life. Pale spots on gene connected by a band across the frons. Very similar to 
P. zoe, 9, but with some black on the metepimeron, probably no pale spots on 10, wings uncoloured 
throughout.

The specific name refers to the black apical twelfth of the wings of the male.

1. Philogenia championi, sp.n. (Tab. V. figg. 3, 4.) 
3g. Labrum and the frons inferiorly pale, perhaps blue in life. Nasus blackish, with two pale spots; vertex 
reddish, rear of the head yellow, labium black. 
Prothorax reddish-brown, black above the base of the first pair of legs. 
Thoracic dorsum reddish, sides and pectus yellowish; mid-dorsal carina, a broad mesepimeral band, a stripe ou 
the metepisternum, and one on the upper part of the metepimeron black with some metallic green 
reflection. 
Abdominal segments 2-6 brown, becoming blackish toward the apex of each segment and inferiorly, 7-10 
black ; 2-3 with a mid-dorsal pale stripe in the basal half, 4-6 with a transverse basal yellow ring, 
represented on 7 by a yellow spot each side at base ; 9 pruinose on dorsum. 
Superior appendages about twice as long as 10, of almost equal thickness throughout when seen in profile, not 
dilated at the apex, which is obtuse and rounded ; somewhat excavated on the supero-internal face in the 
basal half, and for their entire length inferiorly in a trough-like manner. 
Inferior appendages slightly shorter, lamellate, apical fifth bent upward and inward, apex moderately acute. 
Wings transparent, with a very faint smoky tinge. Pterostigma oblique at both ends, dark brown, surmounting 
4-5 cells. Three antenodal cells on the front wings, two on the hind. 23-25 postecubitals on the front 
wings. 
Abdomen 43, hind wing 34 mm. 
9 unknown.

Dedicated to Mr. G. C. Champion, whose field-labours have furnished so much 
material for the present work. 
No member of this genus has previously been recorded from farther north than 
Bogota. The present species is possibly more closely related to P. cassandra than to any
