Mr. C. O. Waterhouse on 
front of the thorax 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 the 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 Nyassa above referred to as 
the probable female of P. Taylori has the punctuation of the 
thorax very similar to that of the male. 1 propose to name 
this specimen provisionally P, Jacksoni. The following is a 
full description: — 
Peclaria Jacksoni \ sp. n. 
Elongato-oblonga, convexa, nigro-fusca, subpurpurascens, sat nitida ; 
thorace creberrime fortiter punctato, antice medio leviter gibboso 
subtilius punctulato ; elytris fortiter striatis, interstitiis planis, 
nitidis, fortiter biseriatim punctatis, interstitio suturali solum 
crebre punctato.

Hah . Arusha (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 emargination 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 punctuation is strong, but the punctures are not 
quite so large as in the foregoing species, crowded at the sides, 
distinctly separated from each other on the disk, fine on the 
anterior swelling, which is very slight ; halfway towards the 
side about nineteen punctures may be counted in a line from 
the front to the posterior margin, the punctures being separated 
from each other at this part by about one half the diameter of 
a puncture. The elytra have the striae strongly marked ; the 
interstices shining, each with a regular line of strong punc- 
tures on each side; the sutural interstice, however, has three 
rather irregular lines of punctures ; in the second interstice 
there are a very few stray punctures.
