Uganda: Entebbe (C C. Goivdey, May). 



There are two specimens in the British Museum. 



T. flaviventris is closely similar to T. tibialis, but the 

 lower surface, as well as the legs and antennae, is pale, 

 and the pale basal patches of the elytra unite at the suture 

 and do not extend to the shoulders. It is rather larger, 

 relatively broader, with the pronotum more strongly punc- 

 tured, the tibise mncii less dilated at the ends, the antennal 

 club more loosely jointed and less short and broad, and the 

 eyes not very small or very finely facetted.

Old Calabar {A. Murray^. 



The two specimens from which this is described formerly 

 belonged to tlie late Alexander Fry, who obtained them from 

 Murray^s collection, from which also P. andrecB and hume~ 

 ralis were described by Crotch. Whether all were actually 

 collected in Old Calabar is perhaps a little doubtful, for 

 P. coccinelloides, Crotch, and P. dorsalis, Gorh., were also 

 attributed by ^Murray to the same locality, and the former 

 at least certainly does not occur there, belonging to South- 

 Eastern Africa (Nyasaland, Portuguese East Africa, Trans- 

 vaal, Natal, etc.). Specimens in the British Museum which 

 I have identified as P. andrece are from the French Congo, 

 The male has in that species a conspicuous round area of an 

 opaque texture upon the posterior half of the elytra. The 

 two specimens of P. nigrocinctus are both males, and the 

 hinder part of the elytra is less shining than the remaining 

 surface, but the area is not definitely circumscribed nor con- 

 spicuous. The red colour is much brighter than in the other 

 species, and the black band is much wider, occupying more 

 than a third of their length.
