As Thomson, in the description of the species just given, makes 

 Pteromahts viaculipennis Walker a possible synonym, the original descrip- 

 tion of that species is appended to the foregoing, for the sake of 

 convenience. It is impossible to decide this from the descriptions. A. 

 piindaius was designated by Ashmead in 1894 as the type of the genus, 

 and again as such, by the same author, in 1904. Further than in the 

 places already cited, the species has not been mentioned again in the 

 literature. The original description of Fierojnalus niaculipe7inis Walker 

 fellows : 



" Pteromalus maculipennis Walker. 



"Corpus mediocre; caput thorace paullo latius : antennae clavatae, 

 crassse, corporis dimidio lengiores ; articuli 50 ad 10 mm. longitudine 

 decrescentes latitudine increscentes ; clava articulo 100, paullo latier vix 

 duplo longior ; thorax ovatus ; prothorax brevis : mesethoracis par- 

 apsidum suturje vix conspicuas : metathorax brevis : abdomen ovatum, 

 subtus angulatum, apice elevatum acuminatum, non compressum, thorace 

 paullo longius et latius : segmentum i mm. magnum : sequeiitia breviora; 

 oviductus occultus ; alee mediocres : nervus cubitalis radiali vix brevier. 



a. Rarely, but probably scattered (utbredd) from Servia to Lapland.
