all with distant, minute serial punctures and transversely 

 rufjosc. 



Scape nmdoratcly elongate, stout, otdy a little thickened 

 apically ; basal joint of funiculus stout, lon;j(.T than l)r<)ad, 

 8ul)trian;^ular, second sli;;litly lon;<er than third ; fourth and 

 fifth transverse ; club obloni;-oval. />''_y.» stout, the tibial 

 hooks well developed ; third tarsal joint sli;^htly expanded 

 and lohate, with distinct slender };rey setae. 



(J. Rostrum thickened and more coarsely sculptured; 

 antennal insertion at, or immediately before, the middle. 

 The specimen mutilated. 



The female of R. pdrvictrni.'i (Dl'i) most nearly resembles 

 this s|)eeics, which latter, however, is lar;^(,*r, more elonnjate, 

 and darker; the eyes are not at all prominent and not easily 

 distinguishable from the punctuation of the head.

Ashburtou. I extracted one pair from the mandibles of 

 a Trichosterniis nntarcticus which was sent to me several 

 years ago by Mr. \V. \V. Smith. 



Rhinanisus subconvexus, sp. n. 



Rufoua, slifihtly tinged with piceous, tarsi and antennae 

 paler, moderately nitid. 



This species is evidently smaller and paler than R. eJon- 

 ffalujt, and though somewhat similar to R. (jracUis as regards 

 sire and colour is less depressed than it is, with the rostrum 

 and antennae shorter, and differently sculptured. From 

 R. parricornis it may be at once separated by an examinatioa 

 of the thoracic sculpture ; this, however, is the nearest 

 species. 



Rostrum distinctly shorter than thorax, xU basal portion 

 evidently narrower than the anterior, distinctly punctate. 

 Head with distinct, not close, and rather shallow punctures. 

 Eyes very slightly convex. Scope short, a good deal in- 

 crassate apically ; second joint of funiculus very little longer 

 than third; club oblong-oval. Thorax hardly at all depressed, 

 finely but not closely punctured on the middle, more dis- 

 tinctly but not clos ly near the sides ; in shape like that of 

 R. parvicurnis. Scutellum small and smooth. Elytra but 

 little depressed, parallel-sided, striate-punctate, the intervals 

 between the punctures nearly as long as the punctures 

 themselves; interstices with fine distant punctures, scarcely 

 at all rugose; apical sculpture a little imlistinct. 



The pale yellowish hairs, though slender, arc quite percep- 

 tible with a good lens.
