half way across, the nervures yellow in the light, black in the dark 

 part of the wings, the stigma yellow to shortly bêyond the base of 

 the radius, the rest black; the récurrent nervure is received in L s£ 

 cubital cellule, clearly separated from the transverse cubital. Basai 

 4 abdominal segments closely, strongly striated, the strisè sfronger" 

 on the basai segments; the area on the 2 nd smooth, small, triang- 

 ular, wider at the base than it is long and bordered by a strong 

 striated dépression; the suturiform articulation narrow, deep, 

 crenulated, not cleft laterally; there is a narrower crenulated 

 furrow on the base of the 4 th and 5 th segments. Ç. 



Length 13 mill.; terebra 34 mill. 



Dima, 20 th September (A. Koller). 



Face rugosely punctured, sparsely covered with stiff black hair. 

 Temples broad, rounded behind, sparsely covered with pale hair. 

 The 4 front legs coloured like the thorax, as are also the hind 

 coxas and trochanters, the rest of the hind legs black except the 

 knees and the spurs and apices of the tarsal joints; the tibiae and 

 tarsi are densely pilose. The head is paler than the thorax. Palpi 

 long, testaceous, densely covered with white hair. The parapsidal 

 furrows are obsolète. 



Iphiaulax lukombensis sp. n. — Rufo-testaceous, the head 

 paler, more yellowish in tint, the antennae, apex of mandibles, stem- 

 maticum (the black not extending over the ocelii), the antennse, the 

 3 rd and following segments of the abdomen, the hind tibise and the 

 basai joint of the hind tarsi to near the apex, black. Wings with 

 3 yellow and 3 fuscons clouds, the basai yellow cloud extending 

 to the innerside of the transverse basai nervure and ouler of the 

 transverse médian, the middle from the parastigma to the apex of 

 the l st abscissa of the radius, touching the top of the cubitus and 

 leaving a small triangular yellow part at the base of the radial 

 cellule, and a longer, narrow one outside the l st transverse cubital 

 nervure, the 3 rd is roundly, irregularly narrowed on the outerside, 

 straight and irregular on the inner, roundly, narrowed posteriorily, 

 on either side of the 2 ad transverse cubital nervure in the discoidal 

 cellule where it reaches the apex of the anterior third; the hind 

 wings are yellow to the base of the radius and cubitus and there is 

 an irregular yellow cloud shortly before the middle, the base 

 trilobate, the apex rounded inwardly. Basai 3 segments of the 

 abdomen somewhat closely striated, except the basai area of the 

 2 ad , which is small, almost semicircular, and the area at the sides 

 of the base of the 3 rd . There are narrow, crenulated furrows on the 

 apex of the 3 rd and 4 Ul and a smooth one on the apex of the 5 th . Ç.
