134. Exeristes tibialis, sp. n. 



$ . A black species, with the central segments badious, and 

 the legs, propleurae and scape mainly flavous. Head nitidulous, 

 very finely and extremely sparsely punctate ; vertex convex and 

 not baccate behind the entire eyes, which extend almost to the 

 base of the piceous and equally strongly bidentate mandibles ; 

 occiput absolutely bordered laterally, and strongly emarginate in 

 the centre ; face nitidulous, obsoletely punctate, with dense long 

 white pilosity ; clypeus strongly discrete and four times as broad 

 as long. Antennif filiform throughout and black, with the scape 

 excised nearly to its base and broadly flavous beneath. Thorax 

 distinctly, evenly and not closely punctate, with the pleurae and 

 sternum subglabrous ; propleurae triangularly above, and an 

 elongate callosity before the radix, stramineous ; notauli distinct, 

 though hardly reaching centre : metathorax with no area, but 

 with long pilosity, lateral carinae entire, spiracles small and 

 circular. Scutellwn normal and somewhat deeply punctate. 

 Abdomen double the length of the thorax, convex, subparallel- 

 sided, with the apices of the evenly and distinctly punctate seg- 

 menrs a little prominent ; basal segment not longer than apically 

 broad, bicarinate to the centre, with the emarginate apex centrally 

 elevated ; second segment quadrate and, with the slightly trans- 

 verse third, conspicuously badious before its apex ; fourth and 

 fifth distinctly tuberculate and subtransverse, with the following 

 smoother and much shorter; venter flavidous and plicate ; terebra 

 five-sixths the length of the body with the spicula ferruginous, 

 the valvulae black and very elongately pilose. Legs fulvous with 

 the anterior coxae, and all the trochanters, stramineous ; hind 

 coxae and tibue stramineous above and blackish throughout 

 beneath ; calcaria pale, slender and very short ; claws curved, 

 small and basally strongly lobate. Wings hyaline, with the radix 

 and tegulae flavous, stigma and costa blackish ; areolet triangular, 

 broader than high, and emitting the distinctly bifenestrate second 

 recurrent nervure from its apical third ; first recurrent of hind 

 wing distinctly postfurcal, emitting nervellus from above its centre. 



Length 13 millim.

Ti/pe in British Museum. 



I have seen a second female of this species of eleven millimetres 

 in length with the abdomen immaculate, the scape only apically 

 testaceous beneath, and the hind coxae not infuscate.
