NEW GENERA AND SPECIES 



points or streaks as in Neuromus testaceus. Meso- and 

 metathorax with a black spot as in sundaicus. Abdomen 

 black. Legs yellow, only the last 3 — 4 articulations of the 

 tarsus brown. Antennae black. 



Wings somewhat narrower and more elongated. The two 

 dark points between media and radialsector are nearly in- 

 visible or absent. The dark spots of the forewing are very 

 indistinct and less numerous than in sundaicus. Nervature 

 of the same colour, but the costalveins of the hindwing 

 yellow. 



Body £ 22 ram., forew. 25—28 mm., hindw. 22—24 mm., ant. 11 mm. 

 Abd. p 12 mm., gr. br. 9 — 11 mm., gr. br. 8^— 9| mm. 

 Cost, forew. 23-25. 

 * hindw. 21—23. 



Habitat : Borneo. 



One female-specimen (the type) from the Mahakkam 

 river, collected by Prof. Dr. A. W. Nieuwenhuis, is in the 

 Leyden Museum. Another defective one from Sandakan, 

 that probably is a male, is in the Paris Museum. 



Neocliauliodes obscurus, nov. spec. 



A very aberrant species, well-characterised by the shining 

 black colour of the body, legs, antennae etc.; only the 

 mouthparts orange, except the tips of mandibles which are 

 black. Antennae serrate in the female. 



Wings broadly oval, black, the humeri orange red, those 

 in the hindwings in lesser extension than in the forewings. 

 Costal-area in the forewing with some hyaline, whitish 

 spots, in the hindwing wholly black. Pterostigma cream- 

 white in both wings, distalwards from it one or two 

 large, hyaline spots in the apicalfield and a somewhat 

 smaller one between media and cubitus in the forewings. 

 In the hindwing this spot reaches more proximalwards 

 and surpasses the radialsector, almost touching the radius. 

 There are in the apicalfield of both wings traces of light 

 streaks in the cells, and in the hindwings are similar
