108 Notes on Australian Coleoptera. 
parts glossy ; tarsi brown. This is the only sort of the genus 
entirely black. 
Sent to me from Rockhampton (Queensland), by Mr. 
Thouzet. 
Helluosoma Resplendens : length 6’ ; strongly punctured ; 
of a beautiful metallic blue; pubescent ; parts of the mouth 
and autenne black ; thorax short; abdomen glossy; elytra 
long and parallel. | 
This beautiful little insect was found near Port Denison 
by my collector, Mr. Girardin. 
Helluosoma Cyanrvpenne, Hope (dinigma), “ Transact 
Ent. Soc. of London ;” length 8°-10’ ; black, brilliant; strongly 
punctured ; thorax impressed; elytra depressed, rather 
broad, of a beautiful blue, densely puncturated and striated. 
Port Denison and Rockhampton. 
Note.—This insect was placed by Hope in the genus 
Ainigma, probably on account of its colouration, but it has 
a tooth to the mentum. | 
Helluosoma Cyanea: length 94’; of a dull, dark blue, 
almost black; general form elongate ; pubescent ; strongly 
punctured ; thorax impressed; elytra long, parallel, of a 
dark blue, strongly punctured and striated.

Wilcox. 
Ainigmaiseasily distinguished by its broad compressed form, 
which makes it very different from the other genera of the 
family. It was established by Mr. Newman ona very beautiful 
insect from Queensland, that he called J7is. Since, Mr. Hope, 
“Trans. Ent. Soc.,” has described two other sorts under the 
same generic name, but one is certainly a Helluosoma, and 
the other evidently does not belong to the genus. 
The Anigma Iris is an insect of the most magnificent 
purple, with the head, thorax, and posterior margin tinged 
with metallic green; its thorax is very broad, transversal, 
very little narrower behind than at its front part. | 
Tt is found not only in Queensland, but also in New South 
Wales, but is very rare in all parts. | 
[ describe as new the two following sorts. 
Anigma Newmanni: length 8’-10'; which is only dis- 
tinguished from the former by the form of the thorax, which 
is less transverse, more cordiform, and much narrower 
behind. It may be a variety of the precedent. 
I have in my collection a specimen from Cook’s River, near 
Sydney.
