This species was described from a single female from Kucking, Sarawak. Since the 

 description appeared in print, additional specimens representing both sexes have been 

 received from the same place ; these were probably collected by Mr. J. Hewitt, and 

 bear the following label : " bred from curious yellow long-lived larvae of about 

 I in. long. Pupa lasted 7-| days. Aug. 1905." 



The following structural characters of the male may be noted : — Palpi of the usual 

 form, long, thin and upturned, considerably longer than the proboscis. Front and 

 middle claws very unequal, the larger simple, the smaller in two specimens with a 

 small tooth near the base, in a third simple. Genitalia : claspers long, thin, slightly 

 swollen towards the tip, with a single short thick terminal spine ; basal lobes of side- 

 pieces hairy, but without differentiated spines or bristles ; lobes of ninth sternite 

 rather prominent and densely hairy ; harpes and unci as in the other species. Under 

 side of abdomen almost entirely dark. 



The structure of the male claspers shows that this species is not at all closely related 

 to any others in the subgenus ; in fact, it is only included here, rather than in 

 Stegomym, owing to its general similarity in colouring to A. obturbans.
