Shorter and stouter than the two preceding. Black ; palpi pale, 

 mandibles and legs feriiiginous, tibiae at the base obsoletely whitish ; 

 head very shghtly narrowed behind the eyes, vertex smooth ; sides 

 of the mesothorax smooth, with a round foveola, continued foi-wards 

 by a hnear impression ; 1st abdominal segment, and most of the 

 2d, limulose ; prothorax beneath, and segments 1 — 3, more or less 

 piceous or rufous ; wings hyahne, stigma and uerviu-es fuscous ; 

 terebra 5 as long as the abdomen. Length, J I4 — 1^ ; ? 2^ ; 

 wings, 4J lines. 



Var. 1, ? . Thorax and abdomen entirely black, 



Var. 2, 2 . Pro- and metathorax rufous ; abdommal segments 

 1 — 2 rufo-testaceous. 



Head smooth and shining; antennas $ 33 — 40-jointed, as long as 

 the body, black, the first two joints piceous; mesothoracic sutm-es 

 rugulose, converging in a rugulose obscure space before the scu- 

 tellum ; metathorax nigulose, very distinctly areated in one sf)eci- 

 men, the two dorsal areas oblong, rounded at the apex, smooth at 

 the base ; abdomen oblong-lanceolate, flattened above ; segment 1 

 hardly narrower at the base, a little longer than its apical width, 

 with two inchoate basal carinsE ; suturiform articulation invisible, 

 or only slightly ai)parent at the sides ; legs stout, fore tarsi nearly 

 twice as long as their tibiae ; recurrent nervui'e rejected ; 2d inter- 

 cubital nervure decolorous. 



Antennae <? 33 — 42-joiuted, longer than the body ; abdomen 

 wholly piceoixs-black ; four posterior femora with a black line 

 above ; tibiae at the base less distinctly pallid. In the Ent. Mag., 

 iv., 47, the number of joints in the antennae is printed 29, which is 

 probably a misprint for 39. Bridgman's specimen has the antennae 

 83-jomted, which agrees with Wesmael's description. 



Parasitism not known. Halitlaj' saj's he had seen 

 one $ ; and his 3 [tahidus] was taken near London by 

 Walker. The 3' has been found recently near Norwich 

 by Bridgman ; the $ in a house at Worcester by Fletcher, 

 and another by me at Lastingham, Yorkshire. Bonelli
