228 EXOTIC NEUROPTERA. 



a line in apical part of wings and between cubitus and hind 

 margin ; spurs present, rather short ; fifth tarsal joint as 

 long as second, third and fourth together ; antennae widely 

 separate at base. 



Type. — Brachynemurus strigosus Banks. This genus in- 

 cludes also Myrmeleon nigriventris Walker, which I have seen 

 from Argentina and redescribe it as follows : 



Aineroniyia nigriventris Walker. — Head yellowish-brown, two 

 black spots on the clypeus, a black mark above the antennae up on 

 front of vertex, latter paler, with black marks, around black spot each 

 side, a submedian pair, and a spot near each eye ; antennae brown, 

 darker toward tip, fully diameter apart at base ; pronotum with a 

 broad dark median stripe, narrowly divided in middle by a pale line, 

 a dark stripe on each posterior side ; thorax densely spotted and 

 streaked with black, and with yellowish marks, a narrow median pale 

 line over mesothorax ; pleura with a broad white stripe under wings, 

 below which it is dark brown or blackish. Legs pale yellowish, femora 

 minutely dotted with black, bristles black, spurs as long as two joints 

 of tarsus ; abdomen dull black, with white hair. Wings hyaline, 

 tinted with fuscous along base, and in subcostal and radial area ; 

 about eight black spots along lower edge of radius, from radial sector 

 out to the stigma, latter black ; about seven smaller black spots along 

 upper edge of the cubitus, the last at the anastomosis ; the veins at 

 these black spots are black, elsewhere pale, other veins more or less 

 marked with black, radial sector mostly dark. Hind wings tinted 

 with dark on basal subcostal space ; a few small dark spots along 

 radius ; the stigma dark, and a very plain black streak in the apex of 

 wing; venation mostly dark, but the subcosta and radius interrupted 

 with pale. Wings rather narrow, both pairs subfalcate and acute at 

 tips ; in fore-wings four cross-veins before the radial sector, in hind- 

 wings three ; about thirteen branches to radial sector in each wing ; in 

 fore-wings the radial sector arises much before the cubital fork, the 

 latter runs nearly parallel to cubitus for some distance, as also does 

 the anal vein, which ends far out in both pairs ; through the radial 

 branches is a straight line toward tip of wings in both pairs. Expanse 

 60 to 70 mm. 



From Misiones, Argentina, also Rio Grande do Sol, 

 Brazil. 



In structure similar to B. strigosus, but the markings are 

 very different. I would not have known this was Walker's 

 species but for a sight of the type.
