Suarp—On New Zealand Coleoptera. 397 
Triphyllus confertus, n. sp.—Oblongo-ovalis, convexus, fusco-ferrugineus, 
prothorace omnium densissime punctato; elytris sparse punctatis, ad basin punctis 
seriatis magnis impressis, ferrugineis irregulariter nigro-tinctis, pubescentia flava 
maculatim vestitis. Long. 2+ m.m. 
Readily distinguished from the other species by the dense punctuation, this on 
the head and thorax is coarse and rugose, there is no basal fovea on the latter, 
The yellow pubescence on the elytra appears to be confined to the red marks, these 
form no definite pattern, but are mixed with the black colour in a very irregular 
and indefinite manner. 
Auckland, Lawson; Picton, Helms. One example from each locality. 
Triphyllus concolor, n. sp.—Ovalis, testaceo-ferrugineus, antennarum clava 
fusca, prothorace sat crebre et fortiter punctato, basi utrinque foveola rotundata 
parvula; elytris parce subtiliter punctatis, ad basin punctis impressis majoribus 
parum conspicuis. Long. 17-24 m.m. 
In this species the serial punctures at the base of the elytra, though present, are 
sub-obsolete. It is remarkable from its resemblance to the European T. suturalis, 
Auct., but it is less convex, much more finely punctate, and the thoracic lateral 
margin is entire, or rather the few serrations present on it are so minute that they 
can only be distinguished with a strong magnifier. 
Auckland, Lawson; Tairua, Broun; Picton and Greymouth, Helms. 
Triphyllus rubicundus, n. sp.—Breviter ovalis, convexus, ferrugineus, nitidus ; 
prothorace crebrius fortiter profundeque punctato; basi utrinque foveola parvula ; 
elytris parce subtiliter punctatis, ad basin punctis majoribus impressis seriatis ; 
metasterno fortiter punctato. Long. 13 m.m. 
Although similar to the smaller examples of T. concolor this is readily 
distinguished by the much less elongate form, and the coarse punctuation of the 
thorax, and still more emphatically by that of the metasternum. 
Nore.—The genus Triphyllus has not yet been noted as occurring in New Zealand; Broun’s 
Handbook gives a description of two species of the neighbouring genus, Typha, which, however, probably 
do not belong to Typha, though I doubt whether they will prove to be Triphylli. The New Zealand 
species of the genushave perfectly the facies of the European T. suturalis, Auct., for which Reitter has 
recently proposed a separate generic name, Pseudotriphyllus (Verh. Ver. Brunn, 1879, p. 89). Reitter’s 
paper is, however, merely a systematic analytical table of the European species, and can scarcely be 
considered a serious attempt to set on a satisfactory basis the genera of these small and neglected 
insects, and the characters he gives to distinguish Triphyllus and Pseudotriphyllus can scarcely prove 
to have generic importance, and I therefore treat the New Zealand species as members of the old genus 
Triphyllus. The neighbouring genus, Typha, likewise occurs in New Zealand, T. fumata, introduced 
no doubt by commerce, haying been sent from Auckland by Lawson. 
Auckland, Lawson.
