Famity—PAUSSID. 79 
ARTHROPTERUS ELONGATULUS. 
‘Long, narrow, of a reddish colour, subnitid, and punctate. Antenne rather short, the first joint nearly 
square and with the angles obtuse, the second to the ninth inclusive three times broader than the length, and 
the last more than twice the length of the preceding one. Head not depressed in front, and with the posterior 
angles rounded. Thorax much longer than the width, very little narrowed behind, and not rounded on the 
sides, with the median line obsoletely carinated, and broadly depressed near the base. Elytra a little wider 
than the thorax, and with the apex tri-emarginate in nearly equal lengths, and produced into acute points 
between the emarginations. Apex of the abdomen nearly black. The external apical angle of the fore tibiz is 
acute, that of the intermediate and posterior tibiz is rather obtuse with the apex subtruncate. 
‘Length, 4 lines.’ 
I have obtained a specimen of this distinct species during the progress of this sheet through the press.

Oxss.—On a careful comparison I can detect no other characters to separate the somewhat larger Port 
Natal specimens from the typical specimen of P. Paussoides, formerly in my Collection, and now in the Hopeian 
Museum. 
From the observations also of Herr Dohrn (Proc. Ent. Soc. Lond. Sept. 1, 1851), it is evident that the 
Pentaplatarthrus Natalensis of the Berlin Museum, and P. 4-maculatus Buquet MS, are mere varieties of Pent. 
Paussoides Westw., more or less distinctly banded with black on the elytra.
