Creagris mortifer (Walk.) 



From Daressalam; Reitfontein, D. S. W. Afrika (at light), 

 and Abyssinia. Probab y occurs over most of Africa. 



Creagris aegyptiacus (Rambur). 



From Egypt (Petersen coll.) ; Bagamoyo and Korogue, D. O. 

 Afrika, also Madagascar. Also widely spread in Africa. 



Peringuey has recently described four other species from 

 South Africa. One, C. angustipennis, ma)- belong to the genus, 

 but the three other species (C. damarinus. C. mashunus and 

 C. bechuanus) are said to have the spurs no longer than the first 

 joint of tarsi; since all the species of Creagris known to me have 

 spurs as long as three or four joints, I can hardly believe that 

 these three species really belong to Creagris. 



Formicaleon n. gen. 



This genus, of the general appearance of Myrmeleon, is at 

 once distingiushed therefrom by having but one crossvein 

 before the radial sector in the hindwings, and by the antennae 

 being close together at base; from the allied genera, Nemoleon 

 and Macronemurus, it is separated by the longer spurs. 



The genus Formicaleo Leach was made for Myrmeleon for- 

 micarins, which was already the type of Myrmeleon; therefore, 

 I am compelled to make a new name for the Formicaleo that is 

 used by Hagen and Brauer. 



The type is Myrmeleon tetragrammicus Fabr. 



There are many species in the African fauna, the few I 

 have seen may be separated as follows : 



1. Two broad black stripes on the yellow pronotum, ami the lower si'les black, 



antennae long anil slender, wings rat In r broad, most of the cross-veins 



brown 2 



Not two broad black stripes on a yell' iw pn inotum 3 



2. Two cross-veins befon radial ector in the hind-wings, stigma rosy, .idoneus 

 But one cross-vein before radial sector in the hind-wings; stigma white. . . . 



lethalis 



3. Hind-wings with a ilark streak in apical part; pronotum pale, with incomplete 



dark lines harpalyce 



No streak in the hind-wings 4 



4. Four dark spots just behind the radius in each fore-wing hesione 



No such spots 5 



.">. Hind part of fore-wings with many small 'lark spots; pronotum dark, with 



two darker stripes; antennaa short lepidus 



Not so (> 



6. Pronotum with a broad median black stripe, and oblique black line in apical 



part of the fore- wings ilione 



Pronotum and wings not so marked 7 



7. Gradates in fore-wings margined with brown; larger species, expanse 80 mm. 



alcione 

 Gradates of fore-wings not margined; smaller species, expanse about 50 mm. 



persephone
