222 EXOTIC NEUROPTERA. 



spots and streaks on sides, but the scutelli wholly pale. Abdomen 

 pale on base, blackish beyond middle, not longer than the wings in 

 either sex, in male the last segment is very short, not nearly as long 

 as the long and slender appendages. Legs pale, with dots at base of 

 the black bristles ; anterior femora dark above near tip ; spurs but 

 little longer than the first tarsal joint. Wings hyaline ; longitudinal 

 veins interruptedly marked with white and black, the cross-veins all 

 strongly dark and most of them almost margined with dark, so they 

 are very prominent ; a dark spot at base of stigma, and another at 

 the end of the cubitus in both pairs ; apical, submarginal forks slightly 

 darkened. Wings moderatly broad ; four to six cross-veins before 

 radial sector in the fore-wings, three or four before radial sector in 

 hind-wings, eight branches of the radial sector in both pairs ; a few 

 costals before stigma forked ; cubitus forks before the first branch of 

 radial sector ; in fore-wing the anal runs out parallel to the hind mar- 

 gin for nearly one-third of wing length ; venation generally ver>' dense. 

 Expanse 55 mm. 



Type. — cf. From rice fields Turricares, Costa Rica, De- 

 cember (Tristan). 



INDOLEON n. gen. 



Wings long and subfalcate at tip : costals simple ; radial 

 sector arises much beyond the cubital fork, ten cross-veins 

 before it, one in the hind-wing before radial sector; no line 

 of bent veins through apex of wings. Antennae long, not 

 diameter apart at base ; pronotum slender ; legs slender, 

 spurs little longer than the first tarsal joint, fifth tarsal joint 

 longer than the first. 



Type. — Myrnieleon tacitus Walk. Probably includes also 

 Myrmeleon iyisignis Rambur, which also has ten cross-veins 

 before radial sector in fore-wings. This genus is allied to 

 Episalus and Periclysius, but differs in that the radial sector 

 arises much farther out, and no line of bent veins in apex of 

 wing. 



Myrmeleon bereiiice n. sp. — Face yellowish, a large inter- 

 antennal mark black, vertex with two transverse rows of three dark 

 spots, the middle one of the front row double ; pronotum pale, with 

 three dark stripes, the lateral sometimes incomplete, meso- and meta- 

 notum mostly dark, but pale behind, pleura partly pale, legs pale, 

 hind tibia dark within, other tibiae and tarsi sometimes infuscated ; 

 abdomen dark, sides with pale stripe, tips of segments narrowly pale. 

 Wings hyaline, veins pale, indistinctly dotted if at all, subcosta with 

 dark spaces, stigma pale. Pronotum broader than long, a little nar-
