parallel to the margin, a second is somewhat oblique, and 
runs from the shoulder to the apex of the elytron, a third 
costa commences at the base close to the suture, and joins 
the second costa some distance (+) from the apex; in the 
discoidal space between these two cost are two large 
shallow coppery impressions, linked together by a very 
short costa; the space next the suture and that between 
the 1st and 2nd mentioned costz is impressed and very 
finely punctured. The abdomen is very thickly punctured, 
coarsely in the middle, finely at the sides; the apical seg- 
ment with a distinct triangular incision at the apex.

Chalcotenia occidentalis, sp. nov. 
C. australasie, Saund. affinis, at latior. Elytris pos- 
tice abrupte attenuatis; marginibus ad apicem denticulis 
6 vel 7 armatis. 
Long. 12—144 lin.; lat. 43—54 ln. 
This insect differs from C. australasie, Saund., in. being 
rather less convex, rather broader, with the surface of the 
elytra less rough, the spaces between the costz flat, and 
very finely punctulate ; the margins have only six or seven 
small teeth at the extreme apex.

HETEROMERA. 
Atryphodes quadridentatus, sp. nov. 
Ater, depressus. Capite planato, fronte utrinque lined 
brevi curvata fortiter impress4. Thorace longitudine paulo 
angustiori, postice bene angustato, margine antico semi- 
circulariter emarginato ; lateribus late reflexis, antice ar- 
cuatim-rotundatis, ante angulos posticos in dentem parvum 
triangularem ampliatis, angulis posticis acute productis ; 
basi leviter emarginato; disco sub-plano, tricanaliculato. 
Elytris basi thorace haud angustioribus, postice latioribus 
(lateribus arcuatis), sat fortiter striatis, interstitiis alter- 
natis costatis. Abdomine nitido. ‘Tarsis ferrugineis. 
Long. 8 lin. ; lat. 34 lin. 
This species resembles A. egerius, Pascoe, but the curious 
double posterior angles to the thorax separates it from all 
its congeners. The second joint of the antennz is very 
small, the third is longer than the two following taken 
together; the fourth to tenth joints become gradually
