122 Rev. T. A. Marshall's monograph of 



head and thorax, stout, filiform, 23 — 24-jointed, testaceous, the 

 apical fourth part, or more, fuscous ; 8 ante-apical joints sub- 

 quadrate ; those of the $ setaceous, longer than the body, 28 — 31- 

 jointed, entirely fuscous, or with the extreme base pale. Prothorax 

 above and on the sides sometimes more or less rufescent. Meta- 

 thorax rather short, obliquely subtruncate behind, finely and irre- 

 gularly rugulose, indistinctly divided into 2 discal arese by 3 carina?. 

 First abdominal segment almost as long as the rest taken together; 

 tubercles not salient ; petiole and condylus reticulato-rugulose, the 

 latter towards the apex with some additional lateral curved stria?. 

 Segment 2 sometimes piceous at the base. Valves of the terebra 

 brown, darker at the apex. Hind coxa? sometimes infuscated at 

 the base ; their femora and tibia? at the apex, with the tarsi, 

 slightly infuscated. Recurrent nervure inserted into the extreme 

 apex of the 1st cubital areolet. 



Described from one female, four males. Not un- 

 common. Taken by Bignell in Devonshire ; by me in 

 South Wales and Wiltshire. Wesmael possessed only 

 one ? , and Ruthe two. According to Haliday the ? 

 occurs amongst fungi in autumn ; it probably has the 

 same habits as obfuscatus, Nees (sp. 11). Common at 

 Shiere, near Guildford : "I have taken," says Capron, 

 in lift., " many females of this species by shaking pieces 

 of Polyporus versicolor. They were in a semi-torpid 

 condition, and fell from the fungus with their legs 

 doubled up, and feigned death ; the males were abundant 

 in the autumn by sweeping." 



25. Mcteoras delator, Hal. 



Meteorus delator, Hal., Ent. Mag., iii., 33, ? . 



"Black, shining; mouth, antenna? at the base beneath, and legs, 

 ferruginous, the posterior infuscated ; segment 1 obconic, elongate 

 and attenuated at the base ; stigma fuscous with a pale spot ; 

 terebra as long as the abdomen. $ . Length, Ik ; wings, 2jf lin. 



"Very like filator, but readily distinguished by the form of the 

 petiole, which is shorter than that of cinctellus (sp. 27), and 

 sculptured as in the preceding species ; segment 2 piceous ; pos- 

 terior legs fuscescent, the base of the articulations paler ; antenna? 

 slender, 23-jointed, obscurely ferruginous at the base beneath. 



" Inhabits with the preceding, but is much rarer." 

 Haliday.
