legs, as well as different locality lead me to consider it a distinct 

 species. 



Expanse 15 mm. 



Navas has placed this genus in the Hemerobiinae, but its extreme 

 likeness to Dilar, leads me to think it is very near that genus and that 

 the male will have pectinate antennae. It has no close affinity to 

 Neurothus, except the one radial sector, a character of no great value, 

 and liable to variation in the Hemerobiidae. 



Notiobiella costalis, sp. nov. 



Type. — British Museum. Africa : Gold Coast, Aburi. Patterson 

 coll. 



Pale greenish yellow (doubtless green in life); veins green, practi- 

 cally all the forkings (except the marginal ones) clouded, the cross- 

 veins margined, and several other clouds in the cells, one series forming 

 a faint band some distance before the tip; hind wings unmarked. 

 Fore wings about two and a fourth times as long as broad, the costal 

 area extremely broad; at origin of the first radial sector the costal 

 area is nearly as broad as the rest of the wing at that place, the middle 

 series of cross-veins not very oblique, and disjointed. In hind wings 

 the radial sector forks twice before the stigma. 



Expanse 11 mm. 



Its broad costal area and shape of superior appendages of the male 

 (Plate 2, fig. 21) separate it from the other described African species 

 of the genus. 



Chrysopidae. 

 Leucochrysa clystera, sp. nov. 



Type.— M. C. Z. 10,060. Colombia: San Antonio, 6,000 ft., 

 February. A. H. Fassl. One specimen. 



Runs to L. montanola or neuralis in Navas table; having radial 

 sector in fore wing partly black; differs from both in pronotal marks, 

 and other points. Face yellowish, unmarked; palpi pale; antennae 

 pale, no distinct stria on the basal joint, a large reddish, median, 

 triangular mark on the vertex; pronotum with a reddish spot at each 

 anterior corner, a large reddish, transverse mark on middle of each side, 

 and the hind border narrowly reddish; eight reddish spots on meso- 

 and metanotum forming two rows; abdomen with transverse reddish
