of punctures, regular at the middle but crowded at the base 

 and apex. 



The specimen from Old Calabar has the front part of the 

 thorax less parallel, slightly narrowed in front. 



Pedat'ia alternans^ sp. n.

Although the punctuation in this species is very distinct, 

 it is nevertheless considerably finer than in any species with 

 which I am acquainted. The head has the angles of the 

 anterior emargination distinctly dentiform, and the side 

 between this angle and the posterior angle is slightly 

 bisinuate. The thorax is slightly constricted at the base and 

 has a very slight sinuosity at the middle of the side. The 

 punctuation (when compared with other species) is rather fine, 

 nearly the same all over ; halfway towards the side about 

 twenty-five punctures might be counted in a line from the 

 front to the posterior margin, the intervals between the punc- 

 tures being a trifle less than the diameter of a puncture; the 

 punctures, however, often touch each other in a longitudinal 

 direction. There is no swelling or tubercle in front. The 

 elytra have the striae rather fine ; the sutural interstice is 

 more closely and rather more i^trongly punctuied than the 

 others. The fourth and sixth interstices have each two 

 regular lines of punctures, the sixth having other punctures 

 at the base. Below the shoulder there is a slightly elevated 

 costa, marked with five or six distinct shining tubercles ; and 

 on the ninth interstice there is a longer series of similar 

 tubercles.

 tuberculato, creberrime fortiter pimctato ; eljtris striatis, inter- 

 stitiis prime et secundo irregulariter piuictatis, reliquis biseriatim 

 punctatis ; carina brevi subhumerali, altera laterali tuberculis 

 parvis instructis.
