the radial sector arises long before end of the anal vein, which is nearly 

 one-half way out on the hind margin; apical portions of both wings 

 have the longitudinal veins very close together. 



Expanse 58 to 68 mm., abdomen 20 mm. 

 Several specimens from Port Darwin, Australia, 8 April to 4 

 May, (Dodd). 



Callistoleon n. gen. 



Wings rather broad ; anal veins of fore-wings ending long before 

 origin of the first branch of the radial sector; posterior branch of 

 cubitus running obliquely down toward anal vein, two series of cells 

 between it and anal vein; about seven cross-veins before origin of 

 radial sector in fore-wings, some crossed; a single series of costal cells; 

 the anterior branch of cubitus and the median vein unite before tip, 

 and from the anastomosis the veins radiate somewhat, to the margin, 

 more strongly so in the hind wings. In the hind wings about four 

 cross-veins before radial sector; the -posterior branch of cubitus 

 running obliquely down to margin, before origin of radial sector; head 

 rather broad; antennae moderately long, pronotum broader than long; 

 tarsal joints short, first much shorter than fifth; spurs a little longer 

 than basal joint. 



Type — Myrmeleon erythrocephalum Leach. 

 Callistoleon erythrocephalum Leach.

Distoleon n. gen. 



"Wings rather narrow ; seven cross- veins before radial sector in 

 fore wings, one in hind wings; anal ends before origin of first branch 

 of radial sector; a single costal series. In hind wings anal ends soon 

 after origin of lower cubitus, not parallel thereto. Spurs as long as 

 first four tarsal joints, fifth joint much longer than first ; tarsus I about 

 as long as tibia I ; pronotum broad. 



Type — D. vertiealis; also includes FoiTnicaleo bistrigatus. 



Distoleon vertiealis n. sp. 



Head pale, a black band below and one above base of antennas, 

 another band above this, narrowly interrupted in the middle or 

 broken into four spots, and on the vertex four spots forming a trapeze 

 in the middle and two each side toward the eye; antenna? brown, 

 annulate with pale; pronotum pale, darker on margin, rest of thorax 

 grayish brown, abdomen blackish, a pale spot above in middle of 

 each segment, legs pale, some black dots at bases of bristles, black 

 and white bristles. Wings hyaline, a dark dot on stigma, one on hind 

 margin one-third the way out at end of anal vein, and two at end of 

 cubitus and median veins, and other smaller spots in apical part of 

 wing, and at forkings of longitudinal veins, these veins black and 

 white in long streaks, some cross-veins all black, others all yellow, 

 others black and yellow. Hind wings with two dots at end of cubitus 

 and less distinctly on apical portion. Antenna? long; legs short, spurs
