branch, first and last branches not twice as long as joint, the 
seven remaining two to three times as long as the joint. 
Pronotum somewhat longer than broad, broadening caudad, 
punctured like the head; mesonotum strongly transverse, scarce- 
ly longer than scutellum, both punctured like the head; parap- 
sidal furrows strongly widened behind, lateral furrows almost 
continuous. Grooves of scutellum separated from each other by 
more than their breadth. Median segment dorsally flat, coarse- 
ly cross-grooved, laterally and posteriorly edged by a groove; 
this is bordered on both sides by a carina; middle part of seg- 
ment with a median longitudinal carina and two lateral oblique 
carine, these converging posteriorly; posterior surface vertical, 
transversely striated, with a median longitudinal carina. Meta- 
pleura closely longitudinally striated; mesopleura coarsely punc- 
tured. 
Wings yellow, shining; pterostigma large, golden yellow like 
the veins; pubescence yellow, very fine and short; radial scarcely 
longer than basal; subcostal near to anterior margin; basal very 
slanting, originating in the distal end of subcostal, much longer 
than transversal, this almost vertical; medial not passing beyond 
the basal cell. Tarsi and distal end of fore tibia rust colored, 
middle tibia with very small, yellow, scarcely visible spines; 
joints of fore tarsus elongate; claw curved, furcate, proximal 
tooth somewhat shorter than the distal one, base of claw with 
a blunt projection. Abdomen strongly convex, gradually taper- 
ing to a point.

Female.—Eyes only punctiform.

This species has hitherto been known only from Fernando 
Po Island, West Africa.
