Perilanguria Fowler. 



Wytsman. Genera Insectorum, Coleoptera, Languriinae (1908) p. 19. 

 Iproposedthis genus with somehesitation, to includecertain African 

 species with no distinet coxal lines and with the eyes moderately 

 or finely facetted or granulate: it must however, be extended so as 

 to embrace at all events the Old World species that fall under this 

 category. 



We may define the four genera Coenolanguria, Perilanguria, 

 Anadastus and Stenodastus as follows: 



Eyes strongly granulate: coxal lines usually absent or if present, raised, 

 divaricate and not distinet. Coenolanguria Gorhara. 



Eyes finely or moderately granulate: coxal lines absent or nearly so. 



Perilanguria Fowler. 



Eyes very finely granulate : coxal lines distinet long, parallel and more 

 or less approximate. Anadastus Gorham. 



Eyes not strongly, but moderately or even rather finely granulate: 

 coxal lines distinet, short, widely diverging. Stenodastus Gorham. 



I prefer to keep the American species by themselves under the 

 typical narae of Languria Latreille, of which genus the common 

 species L. mozardi Latr. is the type : strictly speaking they belong to 

 Perilanguria, as the eyes are finely facetted or granulate and there 

 are no coxal lines : it is open therefore to anyone to sink the last named 

 genus, but in the face of the very large number of species that are 

 perpetually being discovered it is far more convenient to keep the Old 

 and New World species apart. 



Perilanguria sauterana sp. n. 



Subcuneiformis, nitida, capite prothoraceque obscure rufis, elytris 

 obscure aenescentibus vel nigro-eyaneis : capite triangulari, oculis 

 prominulis, leviter granulatis, antennis pieeis, clava 4-articulata : 

 prothorace magno convexo, lateribus rotundatis, marginatis, latitudine 

 paullo longiori, fere'laevi; elytris enneatis, a basi usque ad apicem 

 sensim contractis, leviter punetato-striatis, apieibus conjunetim 

 rotundatis: pedibus pieeis; lineis coxalibus nullis. 



A small shining cuneiform species, with the head and prothorax 

 of a dark rufescent colour and the elytra obscurely aeneous or dark 

 eyaneous: eyes finely granulate, antennae dark with a four jointed 

 club and the seventh joint slightly thickened; prothorax large and 

 convex, a little longer than broad, almost smooth,with the sides evenly 

 rounded and rather strongly margined, the front part of the margins, 

 if viewed from above, being hidden by the convexity of the prothorax: 

 elytra wedge-shaped, contracted from base to apex, distinctly raised 

 just before base, with fine rows of punetures; legs dark; under side 

 finely and diffusely punetured; coxal lines absent. 



Length 4% — 7 1 / 2 mm.
