Fam. PARNID. 
PROTOPARNUS. 
Protoparnus longulus, n. sp.—Oblongo-oyalis, fusco-niger, nitidus, longius pilo- 
sus, antennis pedibusque rufis; sat crebre et sat fortiter punctatus, elytris obsolete 
striatis, striis internis omnino deletis, externis ad humeros profunde impressis. 
Long. 4} m.m. 
This is closely allied to P. vestitus, but is readily distinguished by the more 
elongate form, and the elongate pilosity of the surface; the punctuation, too, is 
coarser and more distant. 
Picton. Helms, one example. 
Mr. Helms informs me that these insects, as I suspected, are not aquatic in 
their habits, but occur under logs in damp places. P. vestitus apparently is not 
very rare about Greymouth, as Mr. Helms has recently been so kind as to send 
me several other examples, which agree exactly with the type. 
Fam. SILPHIDZ. 
CATOPSOLIUS (noy. gen.). 
Corpus subdepressum, nitidum absque pubescentia. Pedes graciles, tarsi 5-arti- 
culati. Antenne graciles, articulo octavo quam contiguis angustiore, clava gracile, 
triarticulata. Palpi maxillares articulo ultimo acuminato, precedente paulo latiore, 
multo longiore. Prosternum ante coxas sat magnum. 
Although very different in appearance therefrom this genus is undoubtedly 
allied to Catops, but the head is not capable of the great inflexion it possesses in 
that genus, and as a correlative fact the front of the prosternum is comparatively 
large. ‘The proportions of the joints of the maxillary palpi are very different from 
those of Catops. From Camiarus the genus is distinguished by the different maxil- 
lary palpi, and by the fact that the epipleuree—very broad at the base, continue to 
the end of the wing cases, becoming gradually narrower behind. The legs are 
remarkably slender, the tibiz quite straight, extremely feebly spinulose externally ; 
the basal joints on the middle and hind feet are much longer than the seconds. The 
front coxze are rather small, not very prominent, and have but little extension in 
the transverse direction, their cavities closed behind and similar to those of Catops. 
The middle coxe are separated only by an excessively narrow process, and the 
mesosternum is not in the least carimate. ‘The hind coxz are very long in the 
transverse, very short in the longitudinal directions.
