Suarp—On New Zealand Coleoptera. 403 
I have seen no other examples agreeing with the unique types of G. fulyus and 
G. similis. 
PROTELATER. 
Protelater elongatus, Shp.—I have received also a nice series of this insect 
from Mr. Helms; amongst them is a well-marked variety, represented by a small 
number of examples, in which the black marks of the elytra are not present, 
or rather are indefinite and diffused over nearly the whole surface of the wing- 
cases, so that these become of a dark-brown colour, with one or two small paler 
spaces over which the dark colour is not diffused. This variety is not connected. 
with the type by intermediate examples, and may be styled var. d. (Plate xm1., fig. 3); 
it much resembles P. huttoni, but has the wing-cases darker im colour, and with the 
alternate interstices more elevated behind, the sides of the body beneath infuscate, 
and the process of the metasternum between the middle coxze broader. 
Fam. DASCILLIDZ. 
AMPLECTOPUS (noy. gen.). 
Corpus parvum, ovale; caput subtus inflexum ; antennze parvee, undecim arti- 
culate, articulis quatuor basalibus majoribus, laxe articulatis, articulis 5-10 per 
brevibus. Prosternum nullum; mesosternum grande, coxis intermediis sat distan- 
tibus; metasternum sat grande, utrinque anterius ad pedorum intermediorum 
receptionem profunde impressum. Coxz posteriores intus magna, a sutura 
recta arcte conjunctis. 
The minute insect forming this very distinct genus will be readily recognized 
by the peculiar antenne, and the fact that the inflexed and retracted head is 
in contact with the mesosternum, which as thus exposed bears a remarkable 
resemblance in form and position to the prosternum, as seen in many coleoptera. 
I have only a smashed example at my disposal for ascertaining the characters, 
and am unable to see the parts of the mouth; the small anterior part of the head 
is prominent, but the mandibles are apparently covered by the labrum, and 
no palpi are visible; the eyes are of moderate size, and the antenne are inserted 
between the eyes; the space between the eye and the base of the mandible 
forming a deep depression for the reception of the base of the antennz in 
repose. The anterior coxz are transverse, and are attached by the base to 
the infolded side of the pronotum, but I cannot detect any prosternum either 
in front of them or between the tips; the femur is rather widely separated 
from the coxa by the interposed trochanter, and the tibia is dilated externally 
near the tip, the minute tarsus being protected by being folded backwards and
