148 NEUROPTERA. 
antenodal ; distal thickened antenodal the sixth or more remote, 
two or more submedian cross-veins, two post-triangular rows out 
to at least the level of separation of principal and subnodal sectors 
(both wings); inferior angle of the ocellar triangle (seen from in 
front) about 90°. Males with the abdomen widest at the 10th 
segment (except in the Bolivian E. lama, where 8-10 are of 
equal width) ; the antero-inferior row of spines on the third tibiz 
much shorter than those of the postero-inferior row and blunt at 
the tip; no inferior distal carina on the tibize, no anal triangle. 
Females with well-developed auricles on abdominal segment 2 . Epicompuus.

A genus of twelve species, extending from the Northern United States to Southern 
Brazil. The “linear or spatulate, median, sternal process on the first abdominal 
segment,” which Prof. Needham ® first appears to have employed as a generic character, 
is lacking in the material of P. complicatus, P. pygmaeus, and P. gracilis which I have 
been able to examine. I have not studied P.(?) paucinervis, intricatus, costalis, 
or polygonus. 
Key to the Mexican and Central-American Species. 
Abdominal segment 1 with a slender median sternal process or tubercle 
(which is sometimes bent and hence lies against the surface of the 
segment). 
Face with dark brown markings on inferior part of frons, on middle of 
nasus, and middle of labrum; pale antehumeral stripe not confluent 
with the green or yellow of the anterior mesothoracic margin ; pale 
metepisternal stripe almost interrupted to form a superior spot and 
an inferior stripe; the mid-dorsal yellow on abdominal segments 3-6 
(when present) linear; wings with the merest trace of brown at 
the extreme base, not reaching even halfway to the basal subcostal 
cross-vein ; superior appendages of the male black, branches of the 
inferior appendage slender, simple. Abdomen, ¢ 43, 2? 40; hind 
wing, 6 382, 933mm. - .. .. . 1. ee ee ew ee 1 ZOnatus.

+ It is usual to quote the ‘ Monographie des Gomphines’ with the date 1857, as is done by Mr. Kirby for 
example, and “ Novembre 1857 ” is, indeed, that which appears on the titlepage of the volume ; but the original 
paper cover bore the date “‘ Mai 1858,” which has usually not been preserved in bound copies. Moreover, 
plates xx.-xxiii. are dated at the bottom as having been drawn in 1858.
