NEUROPTEROID INSECTS FROM SZECHWAN — BANKS 195 



Genus EUROLEON Navas 



EUROLEON ALIENUS Navas 



From Doug Hilen Wei, 10 miles west of Weichow, August 18-22, 

 July 29, 5,600 feet; and 0-Er, 26 miles north of Li Fan, 9,000 feet; 

 both Szechwan. 



INDOPHANES, new genus 



Belongs to the Glenurini; wings much as in Paraglenums {Gle- 

 nuroides). In fore wings the second anal vein runs up close to first, 

 then bends down at an angle to unite to the third; radial sector 

 arises much beyond the cubital fork, about 8 to 10 cross veins before 

 the radial sector; costal cross veins simple, a few beyond middle 

 forked. In hindwings the radial sector arises much before cubital 

 fork, one cross vein before it. Pronotum moderately long; antennae 

 not especially long; legs long and slender, tarsus with basal and apical 

 joints about equally long, spurs long, but equal to only two joints, last 

 tarsal joint not recurved, with many spines below, claws but little 

 more than one half of last joint. 



Type, Myrmeleon harbarus "Walker. 



Includes also M. infestus Walker and M. audax Walker, and the 

 new species below. 



The genus is separated from the other Oriental Glenurini as indi- 

 cated in the following table : 



1. Last tarsal joint recurved, densely clothed below with spreading 



spines ; claws nearly as long as the last tarsal joint Paraglenuriis 



Last tarsal joint nearly straight, not so densely spined, claws 



shorter 2 



2. More than 12 branches to radius beyond union with subcosta ; 



many costal cells four or five times as long as broad ; bristles 



on hind femora but little longer than width of joint 3 



Less than 12 branches to radius beyond union with subcosta; 

 few costal cells ( except near stigma ) more than three times as 

 long as broad 4 



3. Outer fourth of costal area before stigma Avith two rows of cells ; 



forewings not falcate at tip Delgadus 



Only a few costals, if any, before stigma divided; forewings 



plainly falcate at tip Indoleon 



4. Spurs equal to four tarsal joints ; hind femora and tibiae heavily 



spined, lower inner and outer rows of spines Eophanes 



Spurs equal only about two joints ; mid and hind femora only 

 weakly spined Indophanes 



Negrokus Navas, 1930, apparently goes in this tribe; it is said to 

 lack spurs.
