This interesting beetle is fairly common in the онна of Wel- 
lington. Its larva is found in burrows in the solid timber of various trees, 
the ie actually reared having been discovered in the stem of a dead 
nikau-palm (Rhopalostylus sapida). The length of the full-grown larva is 
about Apes It is very stout, with a horny blackish-brown head ; 
cireular horny plate on the back of the second segment and two smaller 
plates on the dorsum of each of the third and fourth segments. The hind- 
y is very soft and fat, ochreous-grey ; the terminal segment is icm 
and very horny, armed above with two strong projecting processes. 
Plate 32, fig. 9.) The pupa win is spent in the burrow inhabited by the 
larva, and the perfect beetle. remains hidden in this retreat for many days 
after its emergence whilst its integument gradually hardens and acquires 
its natural colours.

This Bin active beetle is often abundant under the loose bark of felled 
hinau-trees (Eleocarpus dentatus), especially when saturated with moisture. 
The deis cdi 32, fig. 6), which is even more active, is found in similar 
dem Its length when full-grown is about $in. The antennae are 
three times the length of the head, the body elongate narrow and 
тегез flattened, dull greenish-brown with a pair of pale spots on segments 
5-11 inclusive and a darker dorsal streak throughout. The armature 
on the te segment consists of a long forked process, rising almost 
vertically from the dorsum, and when seen from above very much fore- 
Pig ил This larva is almost certainly carnivorous. The pupa (Plate 32, 
Т) is secreted in a crevice on the inner side of the bark, its terminal 
wipes remaining enclosed in the old larval skin. The beetles emerged 
in December.
