timber, about 12iu., aiul. say. 12ft. lon^’, was perforated 
as in that herewith exhi])ited, and which was cut from it. 
The main i)art of the tree on the ground was in a similar 
state. exce])t that this, being covered by the bark, the 
beetles had found it more difficult to get at, and there- 
fore had pierced it through cracks and crannies, and the 
larvae had committed their depredations therefrom as 
a nucleus or base, ihus leaving i>arts free of attack. 
Like most other Prionidae, Parandra frenchi has a 
much larger head and prothoimx in the male sex than is 
the case with the female. The mandibles of the male are 
evidently cutting instriiments, and their use as such very 
obscure. The antennae are very short, and any ouq not 
knowing larva and pupa might well doubt their classih- 
catioii amongst the Loiigicorns. 
(d) Noteworthy Celeoptera Bred from Ultimate Larval 
Instars. — Collected in the Queensland National Park, 
Macpherson Range. 
Rhipidocerus australasiae. — Hoop-pine and other soft 
woods; also Antarctic Beech (Fagus Moorei) ; pupal 
stadium lasts ten (10) to 12 days. 
Parandra frenchi. Hoop-pine: piqjal stadium about 
15 days- 
Ceratognathus frenchi (?) . — Soft wood, fallen in 
scrub; ])upal stadium 17 days, for 2 specimens only. 
Syndesus cornutus. — Soft wood, fallen in scrub; nu- 
pal stadium about 3 weeks. 
Rhyssonotus nebulosus. — Various fallen timber, pu- 
pal stadium not recorded; ouly one specimen survived; 
beetle common, however. 
Eurhamphus fasciculatus. — ^Hoop-pine ; pupal sta- 
dium, 20 days; only one specimen emerged perfect, but 
several others more or less in a mutilated state; no speei- 
mens were obtained more than half the size of those 
from the pine forests of the Gympie district. 
Alans prosectus. — Predaceous on the larvae of other 
beetles, especially Eurhara]>hus; last larval and pupa! in- 
stars have very variable stadia, sometimes of many 
months’ duration, all through the winter months es- 
I)eeially.
