376 Mr. C. O. Waterhouse on 



front of the tliorax smaller and more shining, but not less 

 elevated. The elytra have the interstices more regularly 

 punctured in double lines, the second and fifth interstices 

 having one or two additional punctures between the lines near 

 the base. 



Another specimen received with the above from Arusha, 

 and agreeing with it in having the interstices of tlie elytra 

 punctured in lines, differs very much in the form and punctu- 

 ation of the thorax and in the almost entire absence of the 

 anterior swelling. It seems unlikely that this should be the 

 female of the specimen with the tubercle with which it was 

 received, as the specimen from Xyassa above referred to as 

 the probable female of P. Taylori has the punctuation of the 

 thorax very similar to tliat of tlie male. 1 propose to name 

 this specimen provisionally P. Jacksoni. The following is a 

 full description : — 



Pedaria Jacksoni, sp. n. 



Elongato-obionga, convexa, nigro-fusea, subpurpurascens, sat nitida : 

 thorace crcberrime fortiter pimctato, antice medio Icvitcr gibboso 

 subtilius puDctulato ; clytris fortiter striatis, interstitiis plauis, 

 nitidis, fortiter biseriatim punctatis, iuterstitio suturali solum 

 crebre punctato. 



Long. 7j millim. 



IJoh. Avusha {F. J. Jackson^ Esq.). 



The head is closely and rather strongly punctured, the 

 punctures very near together, but not confluent ; at the 

 division between the forehead and clypeus the punctures are 

 very feeble, but are stronger again on the clypeus itself; the 

 angles of the anterior enuirgination are slightly dentiform. 

 The thorax has the sides gently arcuate, so that there is not 

 such a suddenly oblique inflexion at the anterior angles as in 

 the above-described species; the sinuosity at the middle is very 

 slight. The ])unctuation is strong, but the punctures are not 

 quite so large as in the foregoing species, crowded at the sides, 

 distinctly scjiaratcd from each other on the disk, fine on the 

 anterior swelling, which is ver}' slight ; halfway towards the 

 side about nineteen ]nincturcs may be counted in a line from 

 the front to the posterior margin, the } unctures being separated 

 from each other at this part by about one half the diameter of 

 a ])UHcturc. The elytra have the stria' strongly marked ; the 

 interstices shining, each with a regular line of strong punc- 

 tures on each side; the sutural intorstiee, however, has three 

 rather irregular lines of junctures; in the second interstice 

 there are a very few t^tray punctures.
