margin of head as from each other. A smooth, longitudinal 
line connects the anterior ocellus with posterior margin of head, 
and a smooth crossline connects the posterior ocelli, thus forming 
across. Frons anteriorly with a weak, rather smooth impres- 
sion. Palpi pale; maxillary palpus at least 4-jointed. Antenne 
brown, geniculate behind scape, first and second joints yellow, 
scape as long as the following two joints together, second joint 
very small, ring-shaped, the following ones thicker, longer, 
cylindric, and hirsute, the hairs almost as long as thickness of 
joints, the third joint fully three and a half times as long as 
thick, the fourth three times, the following ones gradually 
shorter, the twelfth more than twice as long as thick, shorter 
than the last one. | 
Pronotum and mesonotum coarsely and rather closely punc- 
tured, the pronotum somewhat transverse, distinctly longer than 
mesonotum; this truncate anteriorly and posteriorly, the median 
part broader than the lateral ones, parapsidal furrows parallel. 
Scutellum not punctured. Metathorax black, shining; trian- 
gular field of median segment smooth, cross-wrinkled laterally, 
anterior margin of median segment with a row of small pits, 
posterior vertical surface with two longitudinal carine strongly 
converging downward. Metapleura flat, almost smooth, emerg- 
ing toothlike above behind the middle; mesopleura convex, 
coarsely and closely punctured. 
Wings faintly fuscous, subcostal near costal; pterostigma 
lanceolate; radial originating slightly distad of the middle of 
pterostigma, bow-shaped, proximal portion shorter than basal; 
distal portion supplanted by a pale, fine line and longer than 
, the proximal portion, almost reaching anterior margin; basal 
very oblique, curved only at base, three times as long as trans- 
versal, arising in the distal end of subcostal; transversal 
almost vertical; postmarginal wanting; pale lines indicate the 
following veins and cells; the cubitus sinuous, arising from 
distal end of basal and reaching margin of wing; a continuation 
of medial to cubitus; a continuous anal; a closed distal medial 
cell (cubital cell) ; and a closed distal submedian cell (discoidal 
cell). Hind wings with four tiny frenule. Legs yellow, femur | 
and tibia of hind leg dorsally with long, spreading hairs. Abdo- 
men black-brown, smooth, second and third tergites long. 
Length, 3.5 millimeters. _
