362 Mr.F.P. Pascoe on some new Australian Longicornia. 
between the tubers; prothorax broadly ovate, the disk somewhat 
flattened, with small scattered punctures, the sides very rugose; scu- 
tellum very transverse, slightly emarginate behind, its edges consider- 
ably elevated above the elytra; elytra oblong ovate, the discoidal 
carina smooth and nearly entire, the outer carina strongly marked, 
having a somewhat serrated edge, the apex of each elytron rounded ; 
body beneath and legs closely covered with flattish yellowish-grey 
hairs. Length 10 lines. 
Allied to M. Waterhouset (ante, p. 229), but with a broader pro- 
thorax and longer elytra; and at once distinguished by the apices of 
the latter rounded, and the discoidal carina smooth and nearly un- 
interrupted, not broken up into tubercles, as in that species. The 
scutella of the two are, as will be seen, widely different. ; 
Microtragus eremita. 
M. dense griseo squamulosus ; prothorace breviter ovato, fortiter punctato- 
impresso; elytris carina discoidali interrupte piloso cristata, apice sin- 
gulatim rotundatis. 
Hab. The Murray River, South Australia (Mr. Odewahn). 
Closely covered with minute greyish scales; head with the mesial 
line nearly obsolete, except between the tubers; prothorax shortly 
ovate, the disk not depressed, but marked, as well as at the sides, with 
coarsely punctate impressions; scutellum triangular, fitting the elytra 
so closely as to be scarcely distinguishable; elytra rather narrowly 
ovate, the sides with very coarse punctured impressions, the discoidal 
carina with five or six longitudinal tufts of dark short hairs, the outer 
carina not very marked, the apex of each elytron rounded ; body be- 
neath and legs covered with short greyish hairs, with numerous short 
black sets: interspersed. Length 7 lines. 
Resembles the last ; but, inter alia, the disk of the prothorax is not 
flattened, and the discoidal carina is crowned with pilose tufts. The 
scutellum is only to be distinguished by the aid of a good lens*. 
* T have three more species in my collection, all from the Murray River, and 
for which I am also indebted to Mr. Odewahn ; but they are very imperfect. I 
have, however, thought it would be desirable to give their diagnoses for the pur- 
pose of comparison with the above, simply attaching to them the initial only of 
the specific name under which they respectively stand in my cabinet, reserving 
their publication for more perfect examples.
