they are in Coolyardica). Species referable to Polyoptilus by the 
characters indicated above, and not distinguishable by any well- 
marked and obviously generic character from the species already 
attributed to that genus, seem to me best placed for the present 
in Polyoptilus. I make the above remarks with a view to des- 
cribing two new species of Sagrides, which were taken in 
Tropical Queensland by Mr. Koebele, and which certainly do not 
seem to a casual glance congeneric, inter se, and yet one of them 
is evidently closely allied structurally to P. Lacordairei, Germ., 
and the other to P. Hricksoni, Germ. They differ from all the 
known Australian Sagrid genera, except Polyoptilus, as I have 
noted above that Polyoptilus does, and I fail to discover in them 
any well-marked structural character that would decidedly 
separate them from both the species of Polyoptilws named above. 
I may perhaps remark in passing that the description of 
Polyoptilus pachytoides, Baly, reads in some respects as if it 
might have been founded on a female example of the genus 
described above as Neodiaphanops, although I find it difficult to 
believe that if that had been the case Mr. Baly would have 
referred the insect to Polyoptilus. 
P. costatus, sp. uov. Sat parallelus, modice elongatus; fer- 
rugineus, elytris (margine angusto ad suturam et ad latus 
excepto) dilutioribus; capite crebre fortius punctulato ; 
antennis quam corpus vix brevioribus, articulis 2° perbrevi 
3° quam 2™ duplo longiori (his conjunctis 1° equalibus) 4° 
quam 1” vix longiori 5° quam 4" vix longiori 5°—11° 
gradatim longioribus; oculis prominentibus grosse granu- 
latis (ut P. Lacordairei) ; prothorace cordato, leviter trans- 
verso, sat crebre (quam P. Lacordaire: magis crebre) sub- 
fortiter punctulato, mox ante basin constricto, lateribus 
ante medium fortiter rotundatis; elytris costis 4 (his bene 
definitis et ante apicem obsoletis) instructis, interspatiis et 
parte apicali sat crebre subfortiter punctulatis ; tarsis quam 
P. Lacordairei paullo minus elongatis; corpore subtus 
pubescenti ; femoribus posticis subtus (sicut P. Lacordaire?) 
armatis. Long., 44 1.; lat., 131. 
The prothorax is notably longer than wide in all the previously 
described species except Hricksoni, Germ., and Waterhousei, 
Baly, the former of whicu however has antennz not much more 
than half the length of the body their third joint being very 
little shorter than the fourth, while the latter has punctulate- 
striate non-costate elytra. Its strongly prominent eyes (with 
their hind outline, viewed from above, forming a right angle 
with the lateral outline of the head), elongate antennz, pubescent 
under surface, and comparatively slender build connect this 
species much more closely with P. Lacordairet than with 
G
