Head yellow, raouthparts etc. yellow, antennae reddish 

 at the base, ferrugineous towards the middle and getting 

 a black colour towards the club. Club black. 



Legs red. 



Tandjong Morawa (Serdang : N. E. Sumatra). Collected 

 by Dr. B. Hagen. 



Also a cT from Dr. Everts' collection with the locality 

 »Deli, Sumatra", in my own collection. 



Dr. H. A. Hagen mentions in his » Synopsis Hemero- 

 bidarum Synonyraica", S. E. Z. 27 (1866), an Ascalaphus 

 flavicans i. 1. Mus. Berol. from Sumatra which he refers 

 to the genus Hyhris. 



Though I never saw that species, 1 suggest that ray spe- 

 cies is the same as that of the Berlin Museum and there- 

 fore 1 give it the same name. 



The types are in the collection of the Leyden Museum 

 and a couple in my own collection. 



In the Leyden Museum 3 9? 2 of which are immature, 

 and 1 cf from Tandjong Morawa. 



In my collection 1 9 fi*om Tandjong Morawa and 1 cf 

 from Deli. 



Hyhris borneënsis, n. sp. 



Very similar to flavicans and probably only the Borneo 

 representative of it, but distinct by the following characters. 



The male appendices are more of the form of javana 

 Brm. but larger, gradually curved inwards and clothed with 

 long black hairs. The colour is red. The genital valve also 

 has a tooth but this does not surpass the back. Colour of 

 the abdomen as in javana and the black markings of the 

 tergites are all present and broader than in flavicans but 

 not so broad as in javana. Wings limpid like those of 

 javana, veins black excepted subcosta, radius and the 

 insertion which are ferrugineous. 



Pterostigma pitch brown, with 4 crossveinlets. 



Antennae reaching the tip of the pterostigma, fulvous in 

 the basal half, pitchy towards the tip, the club black.
