Genus DELONEURA Trimen 



Deloneura Trimen, 1868, Trans. ent.Soc. Lond. 1868 : 81 ; Aurivillius, 1898 : 287 ; 1920 : 346 ; 

 Murray, 1935 : 58 ; Swanepoel, 1953 : 189. Type-species : Deloneura immaculata Trimen, 

 by monotypy. 



Of the type-species there are only three known specimens, all females, captured by 

 J. H. Bowker on the Bashee River, Kaffraria and preserved in the S. African 

 Museum, Cape Town. I have been unable to examine them and must be content 

 to reproduce Trimen's very full description. 



Head wide, flattened anteriorly, clothed with scales above ; eyes prominent, smooth ; palpi 

 naked, ascending, widely divergent, second segment much swollen, third segment rather short, 

 slender, pointed ; antennae of moderate length, robust, gradually becoming incrassate, the 

 apex slightly curved outwards ; thorax short, robust, smooth, sparsely clothed anteriorly with 

 scales and posteriorly with fine hairs ; legs very robust, smooth, hairless, femur and tibia in 

 all about the same length. 



Trimen considered that among his three specimens there were two males and one 

 female, but in fact all three specimens are females. In consequence he wrongly 

 concluded that the fore tarsus is segmented in both sexes, an error repeated by 

 Bethune Baker (1924 : 202). In 1906 Trimen, when describing D. millari, recog- 

 nized that the segments of the male fore tarsi in Deloneura were fused together, 

 short, and clothed below with fine spines. I have been able to verify this in D. 

 millari dondoensis and D. millari sheppardi. 



Wing venation. Text-fig. 258 is of D. immaculata, after Aurivillius (1898 : 287) ; Text-fig. 

 259 is of D. millari. 



The shape of the wings and their venation in the species of Deloneura have some- 

 times been drawn inaccurately ; in Aurivillius' drawings of D. immaculata the inner 

 margin of the fore wing is shown as straight, whereas Trimen says it is convex 

 basally. Murray (1935 : 58) repeats Trimen's description, but his fig. 6 of D. 

 millari shows only eleven veins on the fore wing, vein 9 having been omitted.
