116 BRITISH ICHNEUMONS. [Z 



utincrtum 



Dfpressaria hcracUana b)' EHsha {I.e. 1884, p. 67). It is apparently rare 

 with us; Elliott captured a inale at Dover on 2nd September, iqoi, and 

 Bankes bred two more on "May 13th and 17th, 1904, from pupae of 

 Clepsis nistkana, Tr., collected in Isle of Purbeck, Dorset, on loth May, 

 IQ04"; the latter are probably co-specific \\ith the last species in sjiite of 

 their distinctly black knees. 



3. annulator, Zcit. 



Porizon annulator, Zett. Ins. Lap. 1838, 394, excl. ? . Linineria genicitlata, 

 Holmgr. Sv. Ak. Handl. 1858, p. 54, <? ? {nee Grav). L. planiscapus, Thorns. 

 O.K. xi. 1105, c? ? . 



A black species with the femora and tibiae fulvous, the hind femora and 

 tibiae apically black, their tibiae centrally not white but nigrescent before 

 the base. Length, 6 mm. 



Very like L. geiiiatJalum in colour, size and conformation, but with the 

 hind tibiae centrally red, the petiole shorter and broader, postpetiole sub- 

 deplanate, w^ith the petiolar sulci deeply impressed from the base nearly 

 to the spiracles, and the lateral postpetiolar lines entire, the vertex angu- 

 larly emarginate and the second 9 segment subtransverse. 



Not uncommon, especially in marshy meadows, in Lapland and 

 Sweden, extending to central Europe ; France, and during July and 

 August in Belgium. It has hitherto been mixed with the last species in 

 Britain too inextricably to allow of division, though many of the records 

 there given doubtless refei- to Holmgren's and not Gravenhorst's genicu- 

 latus. I possess a female from Capron's collection under Holmgren's 

 name, another bred from " Tortrix" by Barrett and a single male, which 

 I swept while collecting with the late Arthur Chitty on 5th May, 1Q07, at 

 L^klingham in Suffolk. 



4. rufifemur, Tlioms. 

 Linineria rufifemur, Thorns. O.E. xi. 1106, i ? . 



A black species with the femora and tibiae fulvous, and the hind tibiae 

 black at their apices and before base. Length, 6-7 mm. 



To Z. annulator, Zett., this species is allied in having the metanotal 

 areola shining and somewhat smooth above, but the hind femora are not 

 apically black and are proportionately less stout with the genal costa sub- 

 inflexed, the basal segment less deplanate and the second a little longer. 



It was described from Sweden and Thomson adds that Dr. Kriech- 

 baumer bred it from Botys scricealis, presumably in Germany. With us I 

 find it by no means rare; Felden in Herts (Piftard) ; Lyndhurst in the 

 New Forest, in August (Adams); Shere in Surrey (Capron). It has 

 several times occurred to me on my house-windows, and on flowers of 

 Angelica syhestris at Monk Soham, in June and August; and on 4th July, 

 1900, I swept a male at Dunwich on the Suffolk coast. 



5. xanthotetoma, Grav. 



Campoplcx[xanthostonius, Gr. I.E. iii. 460, j. Linineria xanthostonia, 

 Thorns. O.E. xi. 1107, c? ? . 



Black, with the femora and tibiae red ; the metathoracic carinae strong 

 and the lateral ones complete ; the mandibles flavous and tegulae white ; 

 and the i^' anterior coxae pale beneath. Length, 7-8 mm.
