Callistoleon. 



Banks, Ann. Ent. Soc. Amer., p.42(1910). 



Wings hyaline, with brownish-black spots. In forewing, lA 

 ends before origin of first branch of radial sector; in hindwing, 

 before origin of radial sector. About seven crossveins before 

 origin of radial sector in forewing, four or five in hindwing. 

 Crossveins in costal area simple. No straight line formed by 

 bent branches of radial sector in apical part of wings. M and 

 Cuj unite before the tip of the wings. Legs short, and rather 

 stout; first tarsal joint a little longer than second; second, third, 

 and fourth of about the same length; fifth twice the length of 

 first; spurs as long as first and second joints united. Front part 

 of vertex much raised. 



Type : Myrmeleon erythrocephalum Leach, (if. guttatus Rbr.). 



The two Australian species known to me may be separated as 

 follows : — 

 Wings rather broad, with large spots along front margin of forewing. 



Head entirely reddish-yellow erythrocephalum Leach. 



Wings slender, smaller spots ah)ng front of forewing in its apical part. 

 Vertex blackish-brown illustreQ^ev^t.{V\. viii., fig.lO.) 



Myrmeleon. 

 Linne, Syst. Nat., xii., p.9 13(1 767). 



Myrmeleon diminutus, sp.nov. (Plates vi., fig.2; viii., fig.ll.) 

 Head yellow. Tip and inner margin of mandibles brown. 

 Palpi yellow. Apical joint of labial palpi fusiform, brown on 

 exterior side. Above antennae, a brown crossband; between the 

 antennae, a narrow brown line. Vertex with several brown 

 spots. Antennae rather short and stout, yellowish, a little darker 

 towards apex; the extreme tip brown; apex of the two basal joints 

 broadly brown, of the following joints narrowly brown below. 

 Prothorax yellowish, a little broader than long, with a brown 

 median stripe, and two shorter lateral ones; meso- and metathorax
