towards the sides of the fourth segment, the impression shallower 

 and different at apex, the spurs of the trochanters shorter, and 

 the hind tibia? very different. The spurs of the hind tibite are 

 readily seen from most directions, but they are much smaller 

 than in the other described species, and appear to consist of a 

 few setee forming a small fascicle. The females are rather shorter 

 and more compact, but otherwise much as in P. Victori(^. From 

 the male of P. mirandus (to which it is closer) it differs in the 

 abdomen being wider, with its impression more pronounced and 

 apex different, the metasternum not bifoveate in front, and the 

 hind tibiae feebly spurred. 



Palimbolus femoralis, n.sp. 



(J. Pale castaneous. Rather densely pubescent. 



Head with a large shallow fovea close to each eye, with an 

 impression from base to apex, deep at apex, fairly distinct at 

 base, but scarcely traceable on middle. Antennae not very stout^ 

 first joint slightly curved, slightly longer than second and third 

 combined, fourth to eighth of about even size and each feebly 

 transverse, ninth larger and moderately transverse, tenth slightly 

 larger than ninth, eleventh ovate, as long as ninth and tenth 

 combined. Prothorax and elytra much as in the preceding species. 

 Metasternuvi with a large semicircular fovea behind each median 

 coxa, each fovea aboixt two-thirds the length of the metasternum 

 itself. Undersurface of abdomen with a wide shallow depression 

 common to .several segments. Four hind trochanters strongly 

 dentate; front femora somewhat curved and each with a strong 

 obtuse tooth, which is provided at apex with a thin elongate 

 fascicle; hind tibise with a strong acute spur at about one-fourth 

 from apex. Length 2| mm.

A single male, without locality, given to me years ago by the 

 Rev. T. Blackburn as Tyrus mirandus Sharp; but evidently not 

 that species, although with similar hind tibiae, 'I'he front femora, 

 however, are very remarkable, and as a species before me (see 

 below) agrees perfectly with Sharp's description of T. mirandus,
