POLYCLISTUS. 299 



It appears to me that Holmgren, Fbrster, and Thomson all 

 described different genera; and Polyclistus were, perhaps, better 

 merged in Exochus if the name had not already been frequently 

 cited, especially by systematists.

$ . A small, shining black, flavous-marked species. Head 

 as broad as thorax, broadly narrowed behind the internally 

 slightly emarginate eyes ; occiput glabrous, abruptly declivous and 

 deplanate ; frons finely punctulate, evenly convex and pilose 

 throughout, with scrobes distinct but cristulae wanting ; face 

 strongly protuberant, evenly convex and coarsely punctate, not 

 discrete from the apically margined and truncate clypeus ; face, 

 mouth (except base and apex of mandibles), cheeks, frontal orbits 

 and a large triangular dot at vertical orbits, flavous. Antennce 

 tiiliform, some\vhat shorter than body, obsoletely pilose, the scape 

 with a flavous mark beneath. Thorax subcylindrical and black, 

 with an elongate flavous callosity before radices ; mesonotum 

 pilose and coarsely, thougli not very closely, punctulate ; notauli 

 punctiform ; metanotum glabrous and discally deplanate, with 

 complete areas ; basal area quadrate ; areola hexagonal and a little 

 longer than broad, emitting costulse near its base ; petiolar area 

 not vertical, short, entire and basally strong. Scutellum at sides 

 and apex, its frenum and whole of postscutellum, flavous. 

 Abdomen nitidulous, punctate and pilose throughout ; two basal 

 segments laterally margined, the first laterally a little explanate 

 throughout, with the disc bicarinate only on its basal third ; 

 venter and the basally concealed terebra piceous. Legs strami- 

 neous ; anterior pairs with pulvilli and extreme base of coxa? 

 infuscate : hind ones with coxae, trochanters and extreme base of 

 femora black ; posterior calcaria very unequal in length, the outer 

 intermediate being particularly short. Wings hyaline and not 

 broad ; areolet wanting : radix and tegulre flavous, stigma narrow 

 and piceous ; basal nervure subcontinuous ; nervellus nearly 

 antefurcal and intercepted near its lower angle. 



Length 5 millim.
