436 Saarp—On New Zealand Coleoptera. 
The prevalent colour is a pallid fuscous, passing in places to a greenish tinge, 
and in other spots to areddish. The front of the head, and also the basal joint of 
the antenna, presents a vertical face, covered with a white pubescence, which is 
denser and more patchy on the middle of the head; in front of the insertion of each 
antenna there is a small pointed projection or tuft. The thorax is without 
punctuation, and has a fine white pubescence on the middle; the transverse line in 
front of the base strongly angulated on either side. The clytra have a very large 
prominence on either side of the suture behind the scutellum, and the third inter- 
stice from the suture projects at the hinder part so as to form a sort of bulla, the 
fifth interstice projecting in a similar though slighter manner ; the strize are rather 
deep, but irregular, and consist of series of rather coarse punctures ; the interstices 
bear a few small fuscous spots or tufts. 
A specimen of this species was sent by Mr. Helms as No. 889, and was found on the racecourse, 
12th Nov., 1880. The female is, I believe, unknown. Anthribus meinertzhageni, Broun, is no doubt 
a Proscoporhinus. This genus was founded on a rare New Caledonian insect, and its discovery in New 
Zealand is of some interest on this account. The entomology of New Caledonia is only very imperfectly 
known, and we may anticipate that a greater affinity will be found to exist between it and that of New 
Zealand than is at present suspected. 
Fam. CERAMBYCIDZ. 
(Emona, Newman. 
Though this is one of the oldest and best known of the New Zealand Longi- 
corns, until recently only one species was recognised. I have for some years been 
aware that there are several species, though I have not previously been able to 
understand them ; but as I have now recognised that the peculiar sexual differences 
in the sculpture of the thorax seen in other genera of the sub-family Cerambycides 
exist in a marked form in this genus, I am able to arrange satisfactorily the 
specimens at my disposal. According to this character there are two groups, 
distinguished by the prosternal sculpture in the male sex ; and I may mention that 
it appears that this is correlative with a well-marked difference in the concealed 
internal supplementary abdominal segment of this sex. In all the species yet 
discovered the femules have the flanks of the prothorax impunctate, while in the 
other sex they are punctate. 
Sect. 1. Prosternum without true punctuation in the male and female. 
(Emona humilis, Newm.—This species is of slender form, with the elytra a little 
attenuate behind, the thorax deeply furrowed by transverse rugee, and, when the 
pubescence is removed, quite shining; the femora and the scape of the antennz are 
infuscate externally. The two sexes are extremely similar, but the male has the
