350 On new Species of Ilisteridro. 



wliicli is complete and on the dorsal disk geminate ; the pro- 

 pygidium is finely not closely punctured ; the pygidium is 

 triangularly excavated at the base ; the prosternum, the keel 

 is rather wide (twice the width of tliat of remex, Lew.), and 

 the strifB are feebly sinuous between the coxie and are widely 

 separate at both ends ; the mesosternum is very deeply 

 incised on either side of the projection, which is somewliat 

 large and obtuse, the marginal stria is fine and complete, but 

 does not follow the anterior edge closely. 



In outline the above is similar to //. remex, Lew., but the 

 thoracic and dorsal stria3 are very different, and the excavated 

 pygidium and the width of the prosternal keel also distinguish 

 it from remex. 



Hah. Jatahy, Province of Goyaz, Brazil. 



MuREXUS, gen. nov. 



Body oblong and with the legs densely muricate, forehead 

 convex ; thorax explanate laterally and anteriorly cut out in 

 semicircular outline; elytra costate; prosternum roughly 

 carinate, anterior lobe tuberculate ; mesosternum bisinuous ; 

 legs elongate, tibiae angulate on the outer edge. 1\ype 

 Terapus inuricatus, Lew. Ann. & Mag. Nat. Hist. vi. p. 28<), 

 pi. 10. fig. 2 (1900). 



The above cliaracters are selected from those drawn for a 

 single species; at present only Terapus il/?«'scec'^e, Mars., and 

 hicarinatus, Lew., are properly referable to Terapus. T. Mar- 

 seulij Westw., more nearly resembles a species of Tylois, but it 

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

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