Catalogue of British Ichneumonida. 371 



apex fuscous ; apical joint of front and middle tarsi fuscous ; hind 

 tarsi fuscous, base of joints palish. Stigma pale fuscous ; tubercles 

 and tegulae whitish. Male and female. Length, 5 mm. 



Taken by Dr. Capron in the neighbourhood of Shiere. 

 This species appears to come very near P. nigricollis, 

 Thorn., but the description is far too short to be certain : 

 he makes no mention of the pale scape, partly black 

 coxa3, or the reddish mark behind the eyes of the female. 



Mesoleius attenuatus, n. s. 



Niger, abdominis medio rufo, pedibus maxima ex parte runs. 

 Head transverse, behind the eyes slightly oblique; antennae 

 filiform, longer than the body; apex of clypeus subtruncate. 

 Thorax about one-third longer than high ; mesonotum distinctly 

 trilobed ; metathorax without areae ; mesopleura scabriculous and 

 dull, disc smooth and shining. Abdomen elongate, slender, longer 

 than the head and thorax ; apex of 4th segment the widest, nearly 

 as wide as the thorax ; 1st segment rather longer than the hind 

 coxa;, petiole slender, sides parallel, about twice as long as wide; 

 post-petiole rather longer than the petiole, apex very little wider 

 than the petiole, finely scabriculous, apex shining, without canali- 

 cula, spiracles placed before the middle ; 2nd segment very finely 

 scabriculous, about one-third longer than wide ; 3rd, sculpture the 

 same, longer than wide, about the same length as the 2nd; 

 remainder transverse. Legs slender ; last two joints of hind tarsi 

 of almost equal length. Wings with an areolet ; transverse anal 

 nervure divided in the middle. 



Black; face, mandibles, clypeus, and scape beneath yellow; 

 segments 2 — 4 of abdomen red ; tubercles and tegulae yellow ; 

 stigma pale testaceous. Legs red ; coxae black, extreme apex of 

 front and middle ones yellow ; trochanters yellow, base of hind 

 pair black; extreme apex of hind femora dark; hind tarsi and 

 apical one-third of hind tibiae nigro-fuscous. Ventral fold pale. 



Male. Length, 8 mm. 



One male taken by Mr. E. Brunetti, who very kindly 



gave me the insect ; it belongs to Sect. A of Mesoleptus 



of Holmgren's Mon. Tryph. Suec, which division he 



afterwards placed in the genus Mesoleius (Disp. Syn. 



Mesol. Scand.), and is very distinct from any of the 



group.
