The female of alternipes closely resembles that of intermedius (Walker) but differs 

 as follows : pronotal collar shorter, its front edge not raised ; funicular segments 

 relatively shorter ; gaster narrower, coppery bronze, with slight greenish reflections 

 only at the base and apex.

Biology. Not definitely ascertained, but probably a parasite of Trypetid flies. 

 Walker (1848a : yy) recorded it as reared from Trypeta parietina [Oxyna parietina 

 L.] but this record cannot now be checked. Imagines June-July.

Type material (all Walker lectotypes bear Waterhouse labels). 



Pteromalus coeruleus Dalman. This species was figured by Dalman but not 

 described (the name merely included in a list). I have not located any specimens 

 so named ; but probably Thomson saw the original material, since he synonymized 

 coeruleus with albipennis (1878 : no) without question. 



Pteromalus cingulipes Walker. Syntypes, 3 $, 2 $. LECTOTYPE, the third 

 specimen, a female ; it is within the range of variation of albipennis although it has 

 an unusually short gaster.
