4. Thorax black, with narrow pair lines 5 



Thorax pale, with a median black stripe over meso and metathorax; the spot 



on hind margin of hind wings is connected along the margin to the apical 

 spot delicatus 



5. Antennae pale, except basal joint and the tip dulcis 



Antennae dark for one-third way out (i 



6. Continental specimens mirabilis 



Madagascar specimens bouvieri 



Cymothales liberiensis Weele, 



From Longji and Victoria, Kamerun; I have one from 

 Sierra Leone. 



Cymothales mirabilis Gerst. 



From Bismarekburg, Togo, and Abyssinia (Petersen coll.) 

 Known from several other localities in Africa. 



Cymothales speciosus Gerst. 



One from Amani, D. O. Afrika. 



Cymothales sp. 



A broken specimen from Kongo, appears to be a new species 

 related to C. delicatus. 



Cymothales delicatus n. sp. 



Face pale, a curved brown mark on each side, a band below antenna-, 

 above brown and on the front part of the elevated portion, vertex with 

 six brown spots in a transverse row in front, and three larger spots in a 

 row behind, each of the latter are nearly double; antenna? with dark 

 mark on basal joint, and a dot each side on the second joint, beyond 

 black for about five or six joints, and then white for three joints, then 

 brown to the tip; pronotum pale with a median stripe brown, and a 

 brown curved line each side in front; rest of thorax dark brown, with a 

 white stripe each side; abdomen pale brown; legs pale, femora mostlj 

 brown, especially above, tibia- with brown dots. Wings hyaline, vena- 

 tion mostly pale, but the veins in dark spots are dark; forewings with 

 a basal spot, with an outer extension behind; a median spot from 

 radius to the median vein nearly square, and narrowly connected to a 

 brown V-mark behind it; a long brown stigmal mark, extending obliquely 

 inward, not so well defined, to near the median vein; slightly behind it 

 begins an oblique, brown streak which extends to the hind margin and 

 in front points toward the tip of the wing; around the tip are several 

 dark spots, but not very distinct, the whole apical area is slightly fumose; 

 the costal area has several of the crossveins marked with brown. Hind 

 wings with a basal brown spot over origin of the radial sector, one on a 

 crossvein from radius to radial sector, about seven crossveins beyond the 

 basal one, another toward the stigma, and one under stigma, the apical 

 part above radius mostly dark, but a narrow apical pale streak, hind 

 margin toward tip has two well separated brown spots, the outer one is 

 connected by brown along the hind margin to the brown at tip, the
