ingly clothed with decumbent, pale yellow, and outstanding elongate 

 hairs, these latter chiefly confined to the sides. 



Head coarsely punctured, the forehead rather less so, with dark re- 

 flexed margins, Avhich are obtusely rounded in front. Thorax only half 

 as long as broad, apex widely emarginate; base distinctly margined, 

 rather deeply bisinuate, so as to appear somewhat lobate, or obtusely 

 prominent, in the middle, its angles obtuse, the sides gently curvedly 

 narrowed towards the front; it is very distinctly punctate, but not as 

 coarsely as the head, and is slightly impressed along the middle. Elytra 

 nearly thrice the length of thorax, of the same width as it is at the base, 

 much broader behind, apices subtruncate; the sutural striae moderately 

 impressed, the others more or less indefinite, quite obsolete near the base, 

 their punctation irregular, similar to that of the thorax. 



Antennae short; 2nd joint nearly as stout as the 1st, but shorter; 

 3rd and 4th of about equal length; 5th very short, simple; club tri- 

 articulate. Anterior tibiae tridendate. 



The somewhat glossy surface, pale colour, very distinct thoracic punc- 

 tation, and the rather lobate base distinguish this from all the other species 

 except White's Rhizotrogus zealandicus (474). In one example the elytra 

 are slightly infuscate.

Titahi Bay, Wellington. One from Mr. A. O'Connor. 



3234. Odontria monticola sp. nov. 



Oblong, a little dilated posteriorly, opaque; light yellowish-brown, 

 and, excepting the head, almost immaculate; the decumbent pubescence 

 rather slender, pale greyish-yellow, the erect setae much more elongate 

 and more scanty; head fusco-testaceous, the middle irregularly dark 

 fuscous, as are also the outer edges of the anterior tibiae and all the tarsi. 



Head very sparingly and coarsely punctured, the reflexed margins 

 of the clypeus gradually narrowed anteriorly and subtruncate at apex. 

 Thorax with the breadth double the length, incurved in front, bisinuate 

 at the base, posterior angles obtusely rectangular, its surface finely and 

 rather distantly punctured. Elytra thrice the length of thorax, with 

 slender striae, which are moderately definite behind but less so near the 

 base; the seriate punctures are blackish, distinct, regular, and small, 

 and are separated by intervals of about the same size as themselves; 

 interstices plane, finely but not closely punctate; apices subtruncate; 

 pygidium short, fuscous. 



Male. — -Antennae short, their 1st joint stout, 2nd shorter, both dilated 

 towards the extremity; 3rd elongate; the 4th nearly as much elongated 

 as the 5th, which is just as long as the other leaflets; the club, conse- 

 quently, is 5-articulate. 



Female. — Antennae short, their 5th joint very short and hardly at 

 all produced; the club is therefore composed of three leaflets. Thorax 

 more sparingly pubescent, so that the fine, though not close, punctation 

 can be easily seen. Elytra with less nigrescent, less regular, but slightly 

 coarser punctures, and therefore with less discernible linear sculpture 

 than in the male, and with a few light-fuscous spots on some of the 

 interstices. 



The stature is about the same as that of 0. striata, but in it the dark 

 lines and serial punctures on the elytra are distinct in both sexes, and 

 the interstices have numerous large obvious dark spots 



Length, 16 mm.; breadth, 9 mm.
