Body c/' 30 mm., forew. 48 — 52 mm., hindw. 42—46 mm., ant. 14 mm. 

 Abd. c/" 15 mm., gr. br. 16 — 18 mm., gr. br. 16 — 18 mm. 

 App. sup. 3 mm. 



Habitat'. Chiua. 



Two males, collected in Mou-Pin by A. David in 1870, 

 are the only specimens known as yet. The types are in 

 the Paris- and in the Leyden Museum. 



Hermes sumatrensis^ nov. spec. 



Nearly related to maculipenms Gray and probably a sub- 

 species of it, but differing by the apical spots of the wings, 

 which are about twice larger than in that species and about 

 one half of those of maculifera Wlk. The creamwhite spots 

 of the forewings are all isolated, more numerous and some- 

 what larger than in macuUpennis. There is no basal cream- 

 coloured spot at the hindborder of the forewings, only two 

 isolated round spots represent the reminiscences of it. In 

 the hind wings this spot is much larger, about as large as 

 in maculifera, and it reaches the anal angle, so that it 

 is about one and a half larger than in macuUpennis. In 

 the middle it has a long apical prominence and it occu- 

 pies about the basal half of the wing. 



As the cf is still unknown, it may be that there are no 

 differences in the gonopoda with macuUpennis or macuUjera^ 

 which both species it seems to connect. 



Body ^ 25 mm., forewing 34 mm., hindw. 30 mm, 

 Abd. 9 12 mm., gr. br. 12 mm., gr. br. 12 mm. 



Habitat \ Sumatra. 



I examined a female from Pajakombo, East Sumatra, 

 collected by the late french naturalist H. Kouyer. The 

 type is in the Leyden Museum. 



Hermes macuUfera tonkinensis, nov. subsp. 



Very similar to macuUfera, but the wings are relatively 

 broader, the white spots less numerous, but larger.
