Head posteriorly constricted ; mandibles and palpi flavidous ; frons 

 somewhat deplanate, with its central carina subobsolete. Thorax with 

 the central metathoracic impression very superficial; basal area complete, 

 dentiparal internally indicated. Abdomen very slender and longer than 

 head and thorax, black with the third and fourth segments entirely, base 

 of fifth and apex of second red ; third segment laterally black-lined nearly 

 to its apex ; basal segment linear and nearly straight ; terebra shortly 

 exserted. Legs flavidous fulvous with the coxae and posterior femora, 

 except apices of the intermediate, black ; the castaneous hind tibiae 

 nigrescent at both extremities; ^ with the front legs flavous and only the 

 coxae basally black. Wings with stigma and tegulae piceous; areolet 

 small, irregular and shortly petiolate, emitting recurrent nervure distinctly 

 beyond its centre; basal nervure subcontinuous through the median. 

 Length, 9 mm. 



Known bv its peculiarly slender form, entirely red fourth segment, 

 complete discal metanotal area, irregular areolet, continuous basal nervures 

 and discally stramineous base of anterior tibiae. 



Originally found by Boheman at Bleking (Holmgr.); north and central 

 Europe (Thoms.), and bred by Brischke from larvae of Cabej-a pusaria in 

 Prussia (Schr. Nat. Danz. 1880, p. 144). Found to be British by 

 Bridgman at Eaton near Norwich in May (Trans. Norfolk Nat. Soc. 1894, 

 p. 619). I possess a series, comprising both sexes, found about Shere in 

 Surrey by Dr. Capron, together with a remarkable male variety, agreeing 

 in every way with the typical form except that the hind trochanters, 

 femora, tibiae and tarsi are totally fulvous. It does not seem by any 

 means common with us, though Lyle has bred it from so ubiquitous a 

 host as Hybernia riipkapraria in the New Forest and tells me it spends 

 nine months of the year in its cocoon. 



24. incompletus, Bridg. 



Campoplex incompletus, Bridg. Trans. Ent. Soc. 1889, p. 420 ; Schm. Opusc 

 Ichn. no. 56, ,i . 



A black species, with only the front legs and centre of abdomen rufes- 

 cent. Head transverse and laterally subparallel ; palpi infuscate, frons 

 with no carina. I'horax dull, with mesonotum closely punctate and the 

 interstices reticulate; mesopleurae dull and densely punctate; metathorax 

 dull and finely rugose with no trace of areae, its central impression not 

 deep and sides white-pubescent. Scutellum sparsely and not finely 

 punctate, laterally margined to its centre. Abdomen black with the 

 third and fourth segments entirely, and apex of second, red ; postpetiole 

 laterally a little rounded and about double length of the apically sub- 

 explanate petiole, spiracles not prominent ; third segment convex below 

 and about three-quarters length of second. Legs black with the front 

 ones except basally, and intermediate tibiae with apices of their femora, 

 flavidous red. Wings with tegulae black and stigma nigrescent ; areolet
