S2 LORD HOWE ISLAND. 



Sapei>ts gayxdahexsis, Mael. 



Saprinus gai/ndaliensis. Macleay. Trans. Eut. Soc. X.S.TT., II, p. 15S (1S71). 

 Two or three specimens of a Saprinus, which were found in stereo re, agree 

 very well with this species. 



TROGOSIT1TLE. 

 Ostoma prnicrM. sp. nov. 



Plate YI. f . 7. 



Ovate, depressed, black, somewhat shining ; prothorax very coarsely 

 punctured on the disc, densely clothed at the sides with light brown 

 appressed scales ; elytra at the base broader than the prothorax, thickly 

 covered with scales, each with seven eosta? composed of bead-like elevations. 



Head transverse, strongly and closely punctured in front, rather less 

 strongly punctured behind. Antennae eleven-jointed, ferrugioous, the club 

 distinctly three-jointed. Prothorax deeply emarginate in front, the sides 

 rounded anteriorly, abruptly narrowed and indistinctly serrate behind the 

 middle. Scutellum transverse, rounded behind, irregularly punctured. Elytra 

 about twice as long as the head and prothorax together, slightly narrowed 

 behind, with broad margins, the costa? moderately raised, shining, interrupted 

 at short intervals by slightly impressed punctures, the interstices flat, the 

 third, fourth, and fifth, considerably broader than the others ; underside 

 dark ferruginous, shining ; sterna coarsely punctured ; abdomen finely and 

 closely punctured. Legs dark ferruginous. Length S — 11 m.m. 



Summit of Mount Ledgbird (2.500 feet) ; also found on the low-lying land. 



The species described above agrees with Ostoma in form and all essential 

 points of structure ; the presternum, however, is much broader behind the 

 coxa?, the margins of the elytra are more dilated, and the form of the 

 elytral co-ta^ is very different. In spite of these difference*, I think the 

 species must be retained in the genus, unless a new one is established for its 

 reception. A variety occurs in which the disc of the prothorax is tinged 

 with bronze. 



COLYDIID.E. 



Xeotrichus LrciFUGrs. sp. nov. 



Elongate, parallel-sided, dark fuscous, thickly covered with erect fulvous 

 seta? ; prothorax distinctly longer than broad, granulose, sides parallel ; 

 elytra strongly seriate-punctate. 



Head broadly tran> verse, strongly rugulose ; eyes very prominent. Antenna? 

 dark reddish testaceous, with the penultimate joint very broad. Prothorax 

 broader than the head, rather thickly covered with coarse granules and short 

 erect seta? ; anterior angles prominent ; the sides explanate and clothed with 

 a row of outstanding seta?. Elytra slightly narrower in front than behind, 

 with series of coarse punctures ; the interstices narrow and bearing erect 

 seta? ; near the humeral angles, which are somewhat prominent, the elytra 

 have a tuberculate appearance. Underside dull, rather strongly and sparingly 

 punctured. Legs fuscous ; the tibia? with conspicuous seta? on the outer 

 margins. Length 4 — h\ mm. 



There can. I think, be no doubt as to the identity of this species with 

 Xeotrichus, recently characterized by Dr. Sharp. It is nearly allied to his 

 -ratus (Journ. Linn. Soc. XIX. p. 117. pi. 6, fig. 1, 1S85), which it 

 resembles in having the surface granulose, and the sides of the prothorax 

 parallel ; but it may be distinguished by its less coarse seta?. The genus 

 would appear to have a wide distribution, as it is now known from Japan. 

 Cevlon, and Lord Howe Island.
