of 30 "-40°, the length of these hairs slightly less than the breadth of the segments that bear 

 them ; sensilla sparse. 



Propodeum rather longer, its median area hardly broader than long. Upper surface of basal 

 cell of fore wing with a few scattered hairs. 



Gaster subcircular, much shorter than the thorax ; basal tergite occupying more than half 

 the total length. 



Holotype $. Sweden : Dalarne, in coll. Thomson under the name submarginatus, 

 in Universitetets Zoologiska Institutionen, Lund. The holotype is pinned and is 

 labelled " Die " [Dalecarlia= Dalarne] and " Bhn " [Boheman].

$. Head and thorax deep blue-green or dark blue, sometimes with weak bronze reflections 

 on dorsum of thorax ; gaster with a blue or green tinge, its disc sometimes bronze. Antennal 

 scape either wholly testaceous, or infuscate distally ; pedicellus usually pale beneath ; rest of 

 antenna fuscous. Coxae concolorous with the thorax ; femora usually more or less infuscate, 

 sometimes only at their base, sometimes mainly ; tibiae sometimes more or less infuscate 

 medially. Wings hyaline, venation testaceous. Length 1-8-2-7 mm. 



Structurally most resembles acuminatus sp. n. and differs only as follows : 



Head (Text-fig. 626) only 1-07-1 -15 times as broad as the mesoscutum. POL 1-3-1-55 OOL. 

 Malar space 0-47-0-5 the length of an eye. Antenna with scape 0-85-0-86 the length of an eye, 

 hardly reaching the level of the median ocellus ; proximal segments of funicle subquadrate, the 

 distal segments slightly transverse ; in small specimens the first segment is a little shorter than 

 the second, in larger specimens it is as long as or even very slightly longer than the second. 

 Median area of propodeum 1-13-1-25 times as broad as long ; median carina usually strong but 

 occasionally weak. Fore wing with marginal vein only 1-18-1-45 times as long as the stigmal 

 vein ; postmarginal vein slightly longer than the marginal. Gaster somewhat longer than the 

 thorax but not quite as long as head plus thorax, 1-7-2 times as long as broad, acute but not 

 acuminate apically ; basal tergite and the two or three following tergites entirely smooth ; 

 last tergite slightly shorter than its basal breadth. 



The female differs from that of exiguus (Walker) mainly in its straighter temples, as seen in 

 dorsal view, relatively larger first funicular segment, and greater average size. From that of 

 maurus sp. n. it differs in its straighter temples, shorter marginal vein, relatively longer gaster 

 and greater average size, and in having 3 teeth in the left mandible. From that of hemipterus 

 (Walker) it differs in its straighter temples, shorter marginal vein and longer postmarginal,
