whole surface : metanotum narrower than the mesonotum, 

 distinctly produced at the lateral angles, and with slightly 

 carinated lateral margins ; castaneous, with a black posterior 

 border formed of three confluent triangular patches ; a fairly 

 well-marked central impressed line, and a few fine punctures 

 scattered over the surface. Abdominal segments black, the 

 first four with castaneous anterior borders^ the second seg- 

 ment concave in front and slightly sinuated behind near to 

 the lateral angles, which are consequently prominent ; re- 

 maining segments rectangular at the sides ; all the segments 

 finely and sparsely punctured, and with slightly carinated 

 lateral margins ; the second and third granulate at the sides 

 behind, fourth segment with a series of small denticulate 

 granules along the posterior margin ; remaining segments 

 covered with small granules ; the supraanal plate is narrow 

 and rounded at the sides ,• cerci broken in the type. Head 

 longer than broad, blackish piceous, with the eyes, antennse, 

 and mouth castaneous ; frons smooth, rather finely and sparsely 

 punctured ; a strongly embossed, transverse, slightly arclied 

 carina in the centre of the face, just in front of the antennas. 

 Femora above piceous, the tibiae and tarsi black ; femora below 

 mahogany-red, flattened, finely and sparsely punctured ; tibiae 

 blackish, coarsely spined at the sides and distal extremities ; 

 flat, and with a few fine punctures below ; tarsi with soft pale 

 stramineous pads ; coxal plates mahogany-red internally, 

 piceous with broad stramineous borders at the sides, from the 

 keeled edge to the outer margin. First two ventral segments 

 with deeply concave anterior margins ; the first segment con- 

 vex behind and subangulated at the lateral angles, remaining 

 segments with concave posterior margins, and the lateral 

 angles rounded off; the whole surface convex, smooth, but 

 covered with fine punctures, the sides also with a few irregular 

 impressed lines ; the last ventral segment is deeply excavated 

 behind in the form of an open /^, but without the acute apex ; 

 the whole of the ventral segments are blackish, the last one 

 with castaneous posterior margin ; subanal plate almost square, 

 but broader in front than behind, and with shelving rugose 

 sides, black with the lateral borders ochreous. Length of 

 body 42 millim., of pronotum 12 millim. ; width of pronotum 

 at the back 15 millim., of mesonotum 18 millim., of metano- 

 tum 19 millim.

^LUROPODA, n. gen. [alXovpo'i^ 7rov<;). 

 Allied to the preceding genus, but differing totally in the 

 form of the thorax, the pronotum of the male being trans- 

 versely trapezoidal, with the anterior margin deeply excavated
