350 On new Species of Histeridfe. 



wliich is complete and on the dorsal disk g-eminate ; the pvo- 

 pygndium is linely not closely punctured ; the pygidiuin is 

 triangularly excavated at tlie base ; the prosternum, the keel 

 is ratlier wide (twice the width of that of remex, Lew.), and 

 the stride are feebly sinuous between the coxae and are widely 

 separate at both ends ; the niesosternura is very deeply 

 incised on either side of the projection, whicli is somewliat 

 large and obtuse, the marginal stria is fine and com})lete, but 

 does not follow the anterior edge closely. 



In outline the above is similar to H. rem.ex, Lew., but the 

 thoracic \nd dorsal strice are very different, and the excavated 

 pygidium and the width of the prosternal keel also distinguish 

 it from remex.

MUEEXUS, gen. nov. 



Body oblong and with the legs densely murlcate, forehead 

 convex; thorax explanate laterally and anteriorly cut out in 

 semicircular outline; elytra costate ; prosternum roughly 

 carinate, anterior lobe tuberculate; mesosternum bisinuous; 

 legs elongate, tibise angulate on the outer edge. Type 

 Terapus niuricntm, Lew. Ann. & Mag. Nat. Hist. vi. p. 28(5, 

 pi. 10. fig. 2 (1900). 



Tiie above characters are selected from those drawn for a 

 single species; at present only Terapus il/n/s^e('/^^, Mars., and 

 h/carinatuSj Lew., are properly referable to 2'erapus. T. Mar- 

 ^eulij Westw., more nearly resembles a species of TyJois, but it 

 has no mesosternal tubercles : Westwood's figure, ' Thesaurus 

 Ent. Oxon.' p. 67, tab. G7. f. 9 (1874), is of course excellent.
