Holotype. — Female, in collection of USNM, no. 69558, Bogor, 

 Java, August 1964, ex scolytid-infested wood, N. L. H. Krauss. 



Allotype. — Male, same data. 



Paratypes. — Six specimens (3 9 and 3 cf ) in collections of USNM 

 and author. All paratypes from same locality as holotype. 



Remarks. — Macromesus javensis is related to M. amphiretus 

 Walker but differs by having a shorter propodeum and different 

 wing veins; the color of the two species also is quite different. 



Figure 6. — Macromesus javensis, new species: a, forewing; b, head in lateral view. 



The genus Macromesus now comprises five species distributed as 

 follows: M. amphiretus Walker (Europe), M. africanus Ghesquiere 

 (Africa), M.filicornis (Delucchi) (Africa), and M. americanus Hedqvist 

 (USA). Macromesus javensis, new species, is the first representative 

 from the Indo-Malayan region. All species are known as parasites of 

 woodboring beetles, especially of the family Scolytidae. The position 

 of Macromesus in the Chalcidoidea is difficult to assess. I think it is 

 best to place it provisionally in the Pteromalidae tribe Macromesini 

 (see Graham, 1959; Ghesquiere, 1963; and Szczepanski, 1959) and 

 await the discovery of more species.
