To the locality given, add :—Costa Rica, Carrillo? (Underwood: 4 3).

PARAPHLEBIA (p. 59). 
An additional species of this genus, and the smallest yet known, has come to light, 
pertaining to group A of the synopsis on page 59, anted. From the characteristics of 
that group, the words “Tips of the wings of the males brown” must now be struck 
out, as the new species has those organs uncoloured. 
1 (a). Paraphlebia abrogata, sp. n. 
3. Differs from the description of P. zoe on p. 60, anted, as follows :—Nasus, frons, and gene opposite 
thereto pale blue, no reddish spots on the vertex; thoracic dorsum obscure in the younger example but 
apparently violaceous, a dark line on each side of the median carina and an ill-defined metallic-green 
antehumeral stripe whose width is one-third of that of the mesepisternum on which it lies, mesepimeron 
black, metepisternum yellowish, a black stripe bordering the second lateral thoracic suture anteriorly, 
metepimeron chiefly black, a pale streak bordering the second lateral suture and another on the latero- 
ventral metathoraciec carina, mid-dorsal thoracic carina and humeral suture pale yellowish ; in the older 
¢ the thoracic dorsum is entirely metallic-green, the median carina blackish, while the other parts are 
coloured as just described; pectus (metasternum) brown in the younger ¢, blackish in the older ¢, 
which latter has abdominal segments 9 and 10 pruinose superiorly. 
Abdominal appendages as described for P. zoe and as figured for P. quinta (Tab. V. fig. 1). 
Wings entirely colourless; median sector in every case arising at, or slightly distal to, the vein of the 
nodus, never proximal thereto; supplementary sectors between the median and the short 4—6 (front), 4-5 
(hind), symmetrically or asymmetrically ; between the superior and the inferior of the triangle 6 (front), 
4-5 (hind), symmetrically or asymmetrically ; antenodal cells always less than one. 
©. Unknown to me. 
Dimensions, ¢ .—Abdomen 39-39°5, hind wing 31:°5-32°5 mm. 
Hab. GuatEMALA, Cacao in Alta Vera Paz (Barber, Lewton, U. S. N. M.: 2 3). 
In the absence of colour on the wings this species resembles P. hyalina, Brauer, 
which I have not seen, but from the description of which it differs in the point of 
origin of the median sector, in the colour of the metasternum, and in its smaller size. 
Paraphlebia duodecima (p. 60). 
To the localities given, add:—GuatemaLa, Sepacuite (Griggs, U. S.N. M.: 1 2, 
immature and in bad condition). 
PHILOGENIA (p, 61). 
The three species of this genus now known from our faunal region are to be 
recognized chiefly by the abdominal appendages of the males.
