Oliloii;:,, ashy black, body an<l legs densely miiricafe, 

 antenn.T obscurely red ; the head, toiehead concave, concavity 

 somewhat smooth, with a lateral stria on either side which 

 becomes carinate anteriorly and terminates in a tubercle, the 

 niandildes arc microscopically sfriat.; ; the thorax is cut out 

 behind the head in a semicircular form, and the anterior anicles 

 are exjilanate, the marj^inate stria is visibli on the anterior 

 edges ot the angles, but it is obliterated laterally by the 

 inuricate sculpture; the elytra are costate, the first costa 

 represents the imier humeral stria, the throe next the 1-3 

 dorsal, the fourth is taint, the fifth and sutural are almost 

 obliterated; the propygidium is sculptured like tlie thorax 

 and the pygidium also, except in the middle where there is 

 a bunch of longer sharp- j)ointed cones and behind them two 

 lines of small tubercles ; the prosternum, the keel is bordered 

 laterally by two rough ridges, which widen out a little from 

 the coxte to the base, on either side of the keel there is a 

 scooped-out lobe-shaped space which is free of tubercles or 

 muricate sculpture and it is bordered outwardly by a carina, 

 the anterior lobe is rough and tuberculate, the keel has an 

 arch-like incision extending across its base ; the mesosternum 

 is bisinuous and bordered by a rough muricate ridge ; the 

 legs, anterior tibite are straight on the inner edge, somewhat 

 sinuous on the outer, which is armed with 6 or 7 irregular 

 denticulations ; the intermediate tibiaj are angulate in the 

 middle of the outer edge, to which point the tarsal grooves 

 extend, outer edge with 11 or 12 irregular teeth, inner edge 

 with small, evenly sot, denticulations, posterior tibitB also 

 ansrular in the middle and denticulated, the thighs on their 

 ui»per surface are conspicuously muricate. 



This curious species ditfers mucli from Terapus Maiizec/ii, 

 Mars., but I do not think it necessary to establish another 

 g<Mius for it. The chief important ditrerences are in the 

 sculpture, in the thorax having explanateangles and not being 

 bisinuous behind the head, in the intermediate and posterior 

 legs being angulate in the middle, and as these angulations 

 are at a point where the tarsal grooves end, the tarsi are 

 relatively longer than in Marscul's species, where the angles 

 are nearer to the tarsal end. In T. bicarinutua, Liw., the 

 thorax is not bisinuous and the tarsal grooves are much 

 shorter than those of T. Mniszechi, but there is no doubt these 

 last two species are congeneric.
