africana, and lastly the colouration of the narrowly expanded 

 reniform part of the hind wings is different.

Gen. CROCE, McLachl. 

 Croce lightfooti, n. sp. 



Body very light drab ; no yellow markings anywhere. Rostral 

 part of head very long, antennae wanting in my three examples, but 

 from memory I can state that they are not long ; pronotum longer 

 than broad, attenuate in front but not constricted there and with 

 only a few, very small setae laterally ; mesonotum distinctly pluri- 

 gibbose ; abdomen twice as long as the thorax (^ c? ), concolorous ; 

 anterior wings hyaline and strongly iridescent, narrow at base, 

 moderately acuminate at apex, plainly fimbriate all round, and with 

 all the nervules distinctly hairy, and light drab in colour ; ptero- 

 stigma very long, partly white partly brown but not very con- 

 spicuous, costal space narrow, divided by not numerous nervules ; 

 hind wings very long, thread-like, slightly more than three times the 

 length of the body, greatly diverging, slightly tapering towards the 

 apex, clothed with a dense short pubescence, and having at about 

 one-third of their length an elongated bunch of silky lanuginose 

 white hairs, occasionally mixed with a few drab ones ; the colour of 

 these hind wings is light drab from the base to about the median 

 part, and thence white. 



The lanuginose bunch varies in size ; it is never very large, but it 

 is quite distinct. This character distinguishes it from C. damara, 

 McLach., which I know, however, from description only, but in 

 which the pubescence of the nervules of the wings is not men- 

 tioned. 



Length of body 9j-9f mm. ; expansion of wings 24-25 mm. ; length 

 of hind wing 35-41 mm.
