but differs in that the dark stripe on the pronotum is as broad 

 in front of the transverse groove as behind it. 



Head mostly black; lower sides of face, clypeus, orbital line, 

 and two submedian spots on the vertex pale yellowish; basal 

 joint of antennas also pale ; spots on vertex sometimes connected. 

 Pronotum with a broad dark median stripe, the anterior part 

 as broad as the posterior, the anterior part with a pale median 

 line. Legs mostly pale, hind femora with a preapical dark band. 

 Abdomen dark, with pale pubescence. Wings hyaline, unmarked, 

 venation pale, with minute dark dots; wings as slender as in 

 M. tenuipennis, the tips acute; twelve branches to the radial 

 sector; seven cross veins before radial sector in fore wing, four 

 in the hind wing; in fore wing the radial sector arising just 

 beyond the cubital fork; two cross veins between cubital fork 

 and anal; one cross vein in hind wing; in the fore wing a few 

 costals before the stigma forked. 



Expanse, 52 millimeters. 



Luzon, Laguna, Los Baiios and Mount Maquiling (Baker). 

 Very close to M. tenuipennis, which I have from northern India 

 and Ceylon. Myrmeleon freyeri Navas is a synonym of M. 

 tenuipennis. 



Myrmeleon celebesensis McLachlan. 



One from Mount Maquiling. Myrmeleon capito Navas from 

 Borneo is the same species, and both are probably synonyms of 

 M. solers Walker from China. 



Genus DISTOLEON Banks 



Distoleon will replace Formicaleo as used by most authol-s. 

 Formicaleo was originally applied only to the type species of 

 Myrmeleon and so is a synonym of it. Formicaleon Banks is 

 a synonym of Distoleon. 



Key to the species. 



a^. In fore wing the branches of cubitus bent to form a line.

6'. The line three to five cells behind the cubitus bakeri. 



a/'. In fore wing the branches, although somewhat bent, not forming a

Face pale; dark spot between antennae, reaching narrowly 

 below and broadly above ; vertex with an anterior, double curved 

 dark band, and behind curved marks which inclose two pale 

 submedian spots. Antennae dark, with pale annuli. Pronotum 

 dark, traces of a pale median line, and a curved pale mark each
