P. Erickson. From P. Lacordaire: it is abundantly distinct 
(apart from its very different colouring) by, inter alia, its short 
prothorax, and elytra with strongly defined (quite costiform) 
elevated lines.

P. torridus, sp. nov. Robustus, sat latus; piceus, antennis 
palpis tarsisqae dilutioribus ; capite et prothorace confertim 
fortiter subrugulose punctulatis; antennis quam corporis 
dimidium vix longioribus, articulis 2°brevi, 3° quam 2"* duplo 
longiori, 4° quam 3" longiori (1° longitudine sat squali), 
5° 4° sat equali, 6°—10° brevioribus inter se sat ezqualibus, 
11° 4° longitudine sat equali; oculis sat parvis sat pro- 
minulis, grosse granulatis; prothorace quam longiori vix 
latiori, cordato, lateribus ante medium fortiter rotundatis, 
margine antico nonnihil elevato ad latera subangulato ; 
elytris lineis subelevatis 4 (his postice abbreviatis) instructis, 
interspatiis et parte apicali crebrius subfortiter punctulatis ; 
femoribus posticis subtus (sicut P. Lacordairer) armatis, 
tarsis sat brevibus (quam P. Hricksoni paullo brevioribus) ; 
corpore fere glabro. Long., 61.; lat., 241. 
This species is of very robust build, even more so than P. 
Ericksoni, Germ.; its antenne and tarsi, moreover, are distinctly 
shorter than in that species When both sexes of the species now 
attributed to Polyoptilus are known I cannot but think it probable 
that Lacordairet and Ericksoni will be found to be generically dis- 
tinct from each other, and if so I suspect that the present species 
will have to be placed in a third genus. It has the nitid glabrous 
undersurface as well as the robust build and short antenne and 
tarsi of the Ericksoni type, but its eyes are of the Lacordairet 
type. Ifit should be found that the female of Hricksoni has 
short elytra and unarmed hind femora (as in Lacordairer) no 
doubt the two might stand as extreme forms of a single genus, 
but I am of opinion that I have both sexes of Lricksoni and that 
the female differs very little from the male externally, being 
however] somewhat larger and having the front tarsi more 
slender. I can, however, find no satisfactory character to 
separate the present insect from Polyoptilus regarded as including 
both Lacordaire: and Erickson.

EDUSA. 
E. puberula, Bohem. In Tr. Roy. Soc., S.A., 1891, 1 furnished 
a paper on Hdusa containing a tabulation of the species known 
tome. In that paper I mentioned Z. puberula as one that I 
had not been able to identify. Since that time I have collected 
in the Blue Mountains, and also received from Mr. Froggatt, an 
Edusa which I have no doubt is that insect. In my tabulation
