172. Exetastes tisiphone, sp. n. 



d . A black and somewhat slender species, with the metatarsus 

 and whole legs (except basally) red. Head somewhat broad 

 behind the eyes ; face evenly and distinctly punctate, with the 

 palpi int'uscate and the mandibles equally acutely bidentate ; 

 clypeus glabrous, with a row of distinct punctures before its 

 evenly rounded apex ; cheeks fully as long as the basal width of 

 the mandibles. Antenna black, filiform, and about as long as the 

 body, with the basal flagellar joint half as long again as the 

 second. Thorax not narrower than head, closely and coriaceously 

 punctate throughout and somewhat dull, with no pale radical 

 marks ; metathorax with fine 

 erect pilosity, but no carinse ; 

 spiracles linear. Scvtellum dis- 

 tinctly punctate and black, not 

 very shining, with its basal fovea 

 conspicuously glabrous. Abdo- 

 men linear, impunctate and very 

 strongly nitidulous, entirely 

 black ; basal segment more than 

 twice as long as apically broad, 

 very slightly widened through- 

 out, with the somewhat con- 

 spicuous spiracles before the 

 centre ; spiracles of second and 

 third segments at their basal 

 two-thirds ; ventral valvulse ex- 

 serted and somewhat large. Legs 

 slender and elongate, pale red, 

 with only the finely punctate coxae and trochanters black ; four 

 apical joints of hind tarsi stramineous, their claws red, slender 

 and simple. Wings a little siliceous, with the narrow stigma 

 rufescent ; tegulae black ; areolet subsessile, emitting the broadly 

 fenestrate recurrent nervure from its centre ; internal cubital 

 nervure with elongate nervelet ; radius very slightly curved above 

 areolet. 



Length 14 millim.

 Type in the British Museum. 



This species is closely allied to E. cinctipes, Eetz., in its meta- 

 tarsal colour, though the body is deep shining black, which, 

 together with the raesonotal punctation, more closely allies it 

 to E. fornicutor, Fab. The elongate nervelet is similar to that of 

 E. femorator, Desv. Described from a single specimen.
