than thorax, oblong, subparallel, apices sHghtly curved, more 

 strongl)' at the outer angles ; they are feebly impressed behind the 

 base, their sculpture similar to that of the thorax, and, like it, 

 clothed with minute greyish hairs. Hind-body rather longer but 

 hardly broader than the elytra, finely sculptured, clothed with 

 distinct yellowish hairs. Legs rather short and stout, front tibiae 

 gradually expanded, apices oblique, spinulose ; the two hind pairs 

 with fine yellow setcE, the posterior rather slender.

Tyrus. 



1866. T. armatus, «-s- Convex, somewhat narrowed an- 

 teriorly, nitid ; head, thorax, hind-body, and antennge jdark-rufous, 

 legs and elytra paler, palpi and tarsi yellow : sparingly clothed with 

 elongate, ei'ect, yellowish hairs. 



Head about as broad as thorax, with interocular foveas and a 

 distinct interantennal furrow ; eyes prominent. Antennce longer 

 than head and thorax, stout ; basal joint large ; second scarcely 

 longer but thicker than third ; fifth rather larger than contiguous 

 ones; ninth and tenth much larger than eighth, obconical ; eleventh 

 largest, suboblong, not acuminate. Prothorax longer than broad, 

 convex, widest near the middle ; smooth, but with a curved im- 

 pression near the base, terminating at each side in a fovea. Elytra 

 rather longer than thorax, twice its breadth, rather broader behind 

 than in front ; each w"ith a sutural stria, deepest at the base, and a 

 short, deep intrahumeral impression ; they are impunctate. Hind- 

 body rather short, convex, much deflexed behind, without sculptiire. 

 Legs long and stout, two front pairs of tibiae flexuous ; posterior 

 slightly bent and thickened, and on the inside, near the apex, armed 

 with a large a,ngular protuberance; tarsal claws small. 



The armature of the hind tibiae at once differentiates this species. 

 The head is decidedly broader than in T. mutandus, the thorax is 

 more convex and hardly contracted at all in front ; the legs are 

 more robust, and the antennae are longer and stouter, the three last 

 joints forming a long, laxly-articulated club.

1867. P. citimus, "••'>■• Elongate, narrowed anteriorly, 

 shining, scantily clothed with minute pallid hairs ; red, palpi and 

 tarsi yellow. 



Head elongate, oviform, the channel between the frontal pro- 

 cesses expanded into a broad interocular cavity, having a linear 

 prolongation on the vertex ; eyes moderate, coarsely granulated. 

 Antenna longer than the head and thorax, the two basal joints stout, 

 cylindric, second half the length of the first, joints 3-8 diffei' but
