86 MANDIBULATA. HYMENOPTERA. 



basal one longest^ the 2nd nearly triangular^ and 3 submarginal areolets^ 

 the 1st small and rounded^ 2nd very long, curved and receiving 2 recurrent 

 nervures ; 3rd extending to the apex : abdomen rather stout, never fasciated 

 with bright colours, elongate in the males, and somewhat cylindric; more 

 robust, and acute at the apex in the females : legs shortish, with 2 short, 

 acute, spurs at the apex of the tibise only. Larva with 16 prolegs. 

 As before alluded to, the insects of this genus may be known from 

 the Dosythei by the abdomen being always black, or having tints of 

 that colour, and never fasciated with red or yellow in the middle, a 

 character invariably present in the Dosythei, which, although the 

 structure of the antennae may not in all cases be sufficient to distin- 

 guish the two genera, will at once enable the reader to discriminate 

 them from each other: and from Emphytus the small, rounded, 1st 

 submarginal areolet, is a conspicuous mark of distinction.

 sionally whitish ; collar bright red ; wings hyaline, with black nervures and 

 stigma. 

 Not uncommon towards the middle of June at Darenth wood, and 



found also in Norfolk. 



Sp. 2. Anthracinus. Antennis abdomine breviorihus, capite thoraceque punctatis ; 

 ovatus, aterrimus. (Long. corp. 4 lin.; Exp. Alar. 9 lin.) 



Te. (Dol.) Anthracinus. King.— Steph. Catal. 338. No. 3938. 



Ovate : body black, clothed with a delicate ashy pubescence ; head and 

 thorax strongly punctured, deep black ; antennae shorter than the abdomen i 

 mandibles black ; abdomen and legs also black ; wings hyaline, the nervures, 

 costa, and stigma black ; tubercles of the metathorax pale. 

 Apparently very rare, taken in June at Darenth wood. 



Sp. 3. niger. Antennis longitudine abdominis, capite thoraceque punctatis, niger 

 lateribus apiceque cano-subpuhescens, abdomine segmentis margine subpellucidis. 

 (Long. corp. 4—5 lin. ; Exp. Alar. 8 — 11 lin.) 



Te. nigra. ira?ie.— Dol. niger. Steph. Catal. 338. No. 3939. 



Deep black, with a fine hoary pubescence, especially on the sides and apex of 

 the abdomen, the segments of which are slightly pellucid on their extreme 

 edges ; head and thorax punctate ; mandibles brown at the tip ; antennaj
