joints of Xylolemus, yet it is probable that it may be ultimately considered 
to be as much allied to Xylolemus as to Bitoma crenata. 
Bitoma nana, n. sp. 
B. fusco-testacea, supra testacea, elytris (prisertim in lateribus) fusco- 
maculatis; prothoraee basin versus angustato, lateribus serratis; 
elytris qualiter seabrosis. Long. corp. 13 m.m. 
Antenne with joints 3-9 small, tenth and eleventh large. Head short, 
yellowish, quite rough and dull. Thorax much narrower than the elytra, 
a good deal narrowed towards the base, the sides coarsely serrate, the 
front angles not acute; it is yellowish in colour, rough and dull, and with 
very indistinct large impressions. Elytra yellowish, with some indistinct 
dark marks on the middle, and a large one covering most of the side; 
their sculpture is very indefinite, but consists apparently of regular rows ot 
coarse punctures, the interstices between which are narrow and interrupted ; 
and they are hispid with short erect sete. The legs are yellowish, short 
and stout ; the femora somewhat infuscate. 
A single specimen, sent from Tairua by Captain Broun. 
This minute species in size and form much suggests a Latridius. It 
appears, however, to be closely allied to B. rugosa, but is very readily 
distinguished by the pale colour and the more ragged sides of the thorax. 
Philothermus nitidus, n. sp. 
P. piceo-castaneus, angustulus, subdepressus, nitidus, fere nudus ; pro- 
thorace parcius fortiter punetato; elytris punetato-striatis, striis 
apicem versus obsolescentibus. Long. corp. 2 m.m. 
Antenne about as long as the thorax, yellowish; the basal joint stout, 
second joint rather slender, but distinctly thieker than the following ones; 
3-9 similar to one another in thickness, the ninth being only slightly 
broader than the eighth; tenth and eleventh joints large, very distinctly 
separated from one another. Head small, immersed in the thorax up to 
the convex eyes. Thorax about as long as broad, straight at the sides, 
which are a little rounded at the front, the hind angles rectangular ; the 
surface bearing rather large but sparing punctures, and with a small and 
indistinct impression at the base on each side. Elytra with rows of dis- 
tinct punctures, which become obsolete at the extremity. Legs reddish ; 
front tibi: rather strongly dilated towards the extremity, 
Tairua : a single individual found by Captain Broun. 
Obs. This species has exactly the appearance of our European species 
of Cerylon ; but the two large and very distinct apical joints of the antenne 
induce me to call it a Philothermus.
