thickened. The puucturation of its head is very much closer and more rugulose 
than in planus ; in the sculpture of its prothorax and elytra it scarcely diflers from 
planus except that its elybral sculpture is considerably more obsolete close to the 
apex. Its front tibite are extremely strongly and closely granulate, the inter¬ 
mediate and hind tibiaj inci’easingly less so. The rufous femora and almost 
testaceous tarsi are in strong contrast to the dark piceous tibiie.

S. addendus, sp. nov. (1). Ovalis ; sat opacus; niger, antennis pedibus et 
corpore subtus rufescentibus ; capite prothoraceque subtiliter crebrius punctulatis; 
hoc valde transverso, antice fortiter angustato, lateribus sat late deplanatis hand 
reflexis; elytris bicostatis, inter costas deplanatis vel subconcavis, sutura hand 
convexa, spatio inter costas in medio subhevi latera versus seriatim punctulato, 
spatio utrinque inter costam et marginem lateralem seriatim magis fortiter punctu¬ 
lato, serierum interstitiis seriatim gninulatis, apiceiu versus puncturis obsoletis et 
granulis minutis confuse dispositis. Long. 8 1. Lat. 4i 1. 
This insect belongs to the group of species which Sir W. Macleay in his 
Revision of the Hekeides (Proc. Linn. Soc. N.S.W., 1887, p. 654) calls the 1st 
group of the 1st section of Saragus. It may at once be distinguished by its 
smaller size from all the previously-described species of that group; from 
S. SpinoUe, Hope, which is scarcely described, it also ditiers inter alia by the 
absence of long hairs on the elytra, and from all the others of the group by the 
lateral margins of its prothorax not being rellexed, and by the space on each 
elytron between the flattened subsutural portion and the lateral margin bearing 
about eight rows of well-detined punctures, the intervals between which are 
granulate, or almost subcostate-tuberculate.

NYCTOZOILUS. 
Of this most perplexing genus there are six examples in the Horn collection 
which it seems impossible to refer to less than four species—all undescribed. 
Five of these specimens all resemble each other so much that to a casual glance
