Catypnes Macleayt. 
C. castaneus, nitidus ; prothorace transverso, irregulariter punctato, utrin- 
que trispinoso; elytris subremote punctatis. 
Hab. Richmond River. 
Dark glossy chestnut, lighter on the elytra; head very large in the 
male, and nearly as broad as the prothorax in both sexes, erosely and 
roughly punctured; mandibles concave above ; eye narrow, nearly en- 
tire ; antenne about half the length of the body, the scape very short 
and subcylindrical ; prothorax transverse, covered with numerous punc- 
tures of various sizes, but generally smaller and more dispersed in the 
middle, the sides with three equidistant spines or teeth; scutellum 
transverse, slightly emarginate behind; elytra scarcely broader than 
the prothorax in the male, considerably broader in the female, covered 
with small and somewhat distant punctures ; body beneath pale chest- 
nut, shining, the postpectus covered with sparse yellowish hairs; legs 
rather short, the tibize unarmed. Length 25 lines. 
Macrotoma papyria. 
M. rufo-testacea; prothorace eroso-punctato, marginibus denticulato, 
disco spatiis duabus triangularibus nitidis ; antennis pedibusque tenu- 
atis, tibiis anticis et intermediis extus denticulatis. 
Hab. South? Australia. 
Rufous testaceous; head shorter and broader than usual, especially 
below the eyes, with confluent impressed points; eyes large, black, and 
less approximate in front; mandibles small ; antennz scarcely half the 
length of the body, nearly filiform, and remotely punctured, the scape 
short, triquetrous, the third joint very little longer than the scape ; pro-

with two large, shining, triangular, and nearly smooth elevated patches 
on the disk, the lateral margins armed with long slender teeth, about a 
dozen on each side, the eighth or ninth longest and recurved ; scutellum 
subtriangular, the sides slightly rounded; elytra narrow, thin, and 
nearly transparent, covered with crowded punctures ; abdomen reddish 
brown, glossy, nearly glabrous, the breast clothed with yellowish hairs ; 
legs rather short, slender; femora nearly smooth beneath ; anterior and 
intermediate tibiee denticulate, but on the outer margin only; tarsi 
slender. Length 17 lines. 
A slight-looking species, with elytra of very thin texture, no arma- 
ture beneath the femora, and the anterior and intermediate tibizw with 
the outer margin only denticulate. 
Three species, which it was my intention to describe in this paper, 
I have been compelled, on a minuter examination, to consider as re- 
presentatives of new forms, and therefore to defer the descriptions 
until they can be figured. One of these has been already alluded to
