Ashmead's type specimen is from the Palearctic region (from Japan) , 

 and is very closely related to B. ornatus Kriechbaumer, from which it 

 can bo separated principally by color and by the shape and length of 

 the epomiae. In B. naivaii the epomiae reach the dorsal margin of 

 the pronotum and are strongly developed or flanged, but in B. ornatus 

 they do not quite reach the dorsal margin and are less strongly de- 

 veloped or flanged. Additional material m.ay show the length of the 

 epomiae more variable in both species. In color pattern the tw^o 

 species are very close, the pattern differing especially on the head 

 and mesopleuron. B. ornatus has the black spot behind the antennae 

 fused with the black of the occllar triangle while in naivaii the two 

 spots are separated. B. nawaii also has more yellow on the meso- 

 pleuron, including a more or less rectangular yellow spot near the 

 center. B. ornatus has no such spot. 



In addition to the type from Japan, I have seen three specimens 

 from the Philippines. One, in the U. S. National Museum collection, 

 Cushman mentioned as being nawaii in his 1936 paper. A second 

 specimen in the Museum collection, from Babatan Island, and one 

 from the Townes collection, from Gapan, may prove, with additional 

 material to show amount of variation, to be a distinct species. The 

 malar space seems a little shorter and the pale bands of the abdomen 

 wider medially on segments 2 and 3. I can find nothing else to 

 differentiate these specimens, so at present can only consider them as 

 being nawaii. 



The distribution for Brachycyrtus nawaii is Atami, Japan, and 

 Manila, Luzon Island, Babatan Island, and Gapan Island, all in the 

 Philippines. The specimen from Manila Avas reared from cocoon of 

 Chrysojya sp.

I have seen no specimen of this species. The "longitudinal striate 

 puncturation" of the mesoscutum and the "pectinate inner spine" of 

 the middle tibia should immediately identify this species. The
