P. ESBEN-PETERSEN, AFRICAN MYRMELEONIDAE. I. 13 



out a string of characters, by which the two European spe- 

 cies may be separated. I supplement those by the following: 

 In the forewing the radial plicate line arises from first brancli 

 from Bs; the connecting-vein between first and second branch 

 is very long in occitanica, rather short in haetica. In the 

 hindwing Cui and Cwj form nearly a right angle in occita- 

 nica, but a rather acute one in haetica. In haetica Cu.^ in 

 the hindwing runs to the margin in a straight direction, in 

 occitanica Cu^ is rather sinuate.

 1853. 



Present one specimen from Melbourne. Spurs bent, not 

 angulate. The contiecting-vein between first and second branch 

 from Rs is very short in the forewing.

In this genus the Gu2 in the forewing is running in 

 straight direction towards the hind margin. In the hindwing 

 Cu^ and 1 A coalesce as in Acanthoclisis. M is rather curved 

 in its apical part, and first branch from Rs forks nearer to 

 the base of the wing than in Acanthaclisis and has at least 

 four branches. The plicate lines distinct with the exception 

 of the line in the intercubital area in the hindwing, which 

 is indistinct in its basal part. Costal area in forewing nar- 

 row, cross veins mostly simple, only forked or sometimes 

 also anastomosed a little before pterostigma. Prothorax 

 broader than long. 



This genus includes several African species, and I am 

 sure that a number of genera, founded on African species 

 during the last years are only synonyms of it. 



Centroclisis distiucta Ramb. — Hist. Nat. Ins. Névr., 

 p. 380, 1842. 



Prothorax with a broad dark median streak, widened 

 towards the hind margin where it encloses a påle oblong 

 spöt at each side; the dark median streak as a rule divided 

 by a påle narrow longitudinal line. At each side of the 

 median streak a dark sinuate and sometimes abrupt streak; 

 side margins dark. Meso- and metathorax with dark streaks.
