Bla¢gkae trike Soc.) S:A., XL, p. 209: 
S. maculigerum, sp. nov. Late ovale; convexum ; nitidum ; 
capillis erectis sparsim vestitum ; nigrum, antennis palpis 
corpore subtus pedibusque plus minus dilutioribus, elytris 
utrinque macula magna discoidali rufa ornatis ; supra sub- 
levigatum ; subtus punctulatum. Long., 4 1.; lat., $1 
The red spot on each elytron is at about half the length, but is 
nearer to the suture than to the external margin. Notwith- 
standing its great difference in size, I cannot find any reason to 
separate this species generically from S. mysticum. 
Queensland ; taken near Toowoomba by Mr. Koebele. 
S. hirtuosum, sp. nov. Sat late ovale; convexum ; nitidum 3; 
capillis albidis sat elongatis erectis sat dense vestitum ; 
obscure rufum hic illic plus minusve distincte infuscatum, 
elytrorum sutura anguste nigra ; supra leviter vix perspicue, 
subtus sat manifeste, punctulatum. Long., 1 1. (vix); lat., 
=a. 
This species is much like S. mysticwm, Blackb., in miniature, 
but of a brighter red color, the head and prothorax scarcely in- 
fuscate, the pilosity more conspicuous, and some puncturation 
traceable on the upper surface.

TRICHORCUS (gen. nov. Coccinellidarum). 
Ab Orco- differt corpore haud wmetallico, subopaco, dense 
pubescenti. 
I can find no structural character to distinguish the genus from 
Orcus, but it seems scarcely possible to place in that genus a non- 
metallic subopaque species densely clothed with pubescence. 
T. cinctus, sp. nov. Hemisphericus; dense fulvo-pubescens ; 
subopacus; supra brunneus, prothorace nigricanti (basi 
excepta) albido-marginato, elytris externe testaceo-marginatis 
(margine a basi retrorsum gradatim dilatato); subtus nigri- 
cans, abdomine testaceo ; confertim subfortiter punctulatus ; 
clypeo antice late sat fortiter emarginato et ad latera ante 
oculos dilatato; prothorace antice profunde bisinuatim 
emarginato, ante basin linea transversa minus distincte 
impresso ; antennis palpisque labialibus flavis, illis apicem 
versus infuscatis. Long., 14 1.; lat., 2 1. 
This remarkable insect is actually a trifle wider than long. I 
have seen nothing at all near it. 
N. 8. Wales; taken near Sydney by Mr. Koebele.
