always présent; basai deflection of Cm lying the fork of M, approxi- 

 mately equal to or longer than Cu%. In the species of the af ricana group, 

 the branches of M diverge strongly, producing a very deep, hexa- 

 gonal cell ist M2 which is irregular in shape, m always shorter than 

 the outer deflection of M3. The venation is rather uniform throughout 

 the genus; in L. duchaillui, sp. n., Rs is of rather an unusual length, 

 being at least three times i?2+3. 



The Ethiopian Lecteris fall in two more or less natural divisions, 

 the first, which may be called the africana group, including large to 

 very large species in which the wings are never cross-banded and 

 there are no spinous setae at the origin of the basitarsi; this group 

 includes the following species : africana Alex., africana nigrilinea 

 Alex., atricauda Alex., pluriguttata Alex., tanganics Alex., tibi- 

 alis, sp. n., and vasta Alex. The second division, which may be ter- 

 med the triacanthos group, includes smaller species in which the wings 

 are often conspicously cross-banded with brown, and the legs are 

 usually variegated with white or yellowish annuli, usually on the 

 tibiae but sometimes best indicated on the basitarsi (hirsutipes, meta- 

 tarsalba and reisi). In a few species (simpsoni and triacanthos) the inter- 

 spaces between the cells are conspicuously dotted with brown. In al] 

 the species, (excepting hirsutipes, in which the character has not been 

 described), one to three spinous setae are developed at the origin 

 of the basitarsi, so close to the tibiae as to simulate tibial spurs. The 

 species included in this group are as follows : duchaillui, sp. n., hir- 

 sutipes Ried., laticincta Alex., metatarsalba Alex., simpsoni Alex., 

 and triacanthos Alex. 



The nearest relatives of Lecteria are the gênera Clydonodozus 

 Enderlein and Conosia van der Wulp, in which the maxillary palpi 

 are reduced to a minimum.

1. Wings without a distinct spotted or banded pattern, the mark- 



ings confined to small spots, and seams along the veins, chiefly at 



the origin and fork of Rs, the fork of i?2+3 and tip of R2; less distinct 



seams along the cord; no spines at origin of basitarsi. 2
