Head not posteriorly constricted, with vertex broad and not transversely 

 convex; eves apically divergent and very large, as also are the ocelli, 

 especiallv in (J ; temples and cheeks buccate, finely rugose and some- 

 what dull ; mouth rufescent. Antennae basally rufescent ; flagellum not 

 stout, ai)ically slightly attenuate, of 9 ^^'ith eighteen or nineteen and of 

 (J with twenty-two joints ; the first half as long again as the cylindrical 

 second. Thorax with deeply impressed notauli; metathorax not rugose, 

 with basal area elongate-quadrate and costae weak ; pleurae finely and 

 rugosel}- punctate or in i^ almost smooth ; sternauli deep, curved and 

 slightlv crenulate. Abdomen elongate fusiform, laterally compressed ; 

 castaneous with first segment black and the remainder laterally rufescent 

 and apically rufescent flavidous ; basal segment somewhat stout, sulcate ; 

 terebra as long or nearly as long as abdomen. Legs somewhat stout and 

 usuallv entirely testaceous, rarely with the hind coxae basally or entirely 

 piceous. Wings hyaline with the nervures and broad stigma rufescent ; 

 tegulae flavidous or piceous; radial branch extending nearly to apex of 

 wing; recurrent nervure subcontinuous. Length, 6-7 mm. 



This is distinguished from all other species of this genus by the apic- 

 ally explanate face and by the peculiarly large eyes and ocelli. 



Freiburg, northern Germany and Denmark ; bred from a species of 

 Hallomaius (Thomson). It was introduced as British by INLarshall in his 

 1870 Catalogus, but no one has recorded it and I do not know it. 



6. rufipes, Hohngr. 



Thersilochiis rufipes, Holmgr. Sv. Ak. Handl. 1858, p. 145, i ? . Diaparsus 

 rufipes, Thorns. O.K. xiii. 1377, i 9 . 



Head transverse, little nitidulous and somewhat constricted posteriorly; 

 mouth and clvpeus testaceous with the latter smooth and ai)ically broadly 

 rounded. Antennae somewhat stout ; flagellum 24-joinled in S 'i" J 

 22-jointed in 9 . whose antennae are basally testaceous beneath. Thorax 

 stout and somewhat shining with basal area often incomplete ; pleurae 

 centrally smooth, with deeply impressed and slightly crenulate sulci. 

 Abdomen laterally compressed and entirely black with only the second 

 segment partly badious, though Thomson gives the abdomen as piceous 

 with basal segment black and the third apically red ; basal .segment 

 slightly curved and longer than hind coxae and trochanters, second 

 hardly longer than broad, and terebra distinctly shorter than abdomen. 

 Legs testaceous with the hind coxae black and base of front ones rarely 

 piceous. Wings hyaline with stigma infuscate, tegulae dull flavidous and 

 radius apically straight. Length, 5-6 nnn. 



Holmgren's variety with terebra as long as abdomen and only basally 

 infuscate hind coxae will probably prove to be a good species. 



France ((laulle), Belgium in July and August (Tos(.]uinet), Sweden 

 (Thomson) and southern Lapland (Holmgren). It appears somewhat 

 sj)asmodic in its appearance with us for Bridgman .says "At the end of
