5 14 ]Mr. D. Sharp's descriptions of 7iew genera 



femoribus summo basi spina elongata armatis ; metasterno 

 apice depresso ; abdomine segmentis ventralibus medio 

 deplanatis. 



Fern, incog. 



Antennae longer than head and thorax, slender till near 

 the extremity, then thickened and as it were twisted. 

 Head only moderately long, densely punctured, opaque, 

 the eyes small and placed at a distance from the hind part. 

 Thorax rather strongly transverse, the disc impressed, and 

 in tbe middle of the impression with an indistinct shining 

 fovea-like space. Elytra indistinctly punctured, clothed 

 with very fine and very short depressed setae, Avhich are 

 not more numerous at the apex than elsewhere. Hind 

 body with the basal depression deep, at its bottom are two 

 large patches of glandular pubescence; posterior part of 

 hind body with numerous elongate erect seta?. 



N. W. Australia. A single individual of this very 

 distinct species (collected by Du Boulay) is all I have seen. 

 The structure of its antennae approaches that of A, Duhou- 

 layi, from which species however its elongate, slender, and 

 uncompressed tibige abundantly distinguish it. 



Articerus Deyrollei, n. sp. Ferrugineus, dense sub- 

 tiliter punctatus, opacus ; antennis capitis thoracisque fere 

 longitudine, extus fere rectis, apice intus incrassatis ; pro- 

 thorace oblongo quadrato, basi leviter impresso ; abdomine 

 crebre punctulato, setis elongatis, erectis, tenuissimis parce 

 adsperso. Long. corp. \^ mm. 



Mas, tibiis anterioribus intus infra medium spina minuta, 

 intermediis intus paulo ante apicem dente acuto ; abdomine 

 apice deflexo. 



Head rather long, the eyes not prominent, placed at 

 a distance from the back. Thorax rather longer than 

 broad, quite straight at the sides, densely and rather finely 

 punctured, in front of the base with a longitudinal de- 

 pression which is not very well defined. Elytra finely 

 and rather closely punctured, their pubescence very fine, 

 short and depressed. Hind body elongate, with a rather 

 elongate basal impression, which is without patches of 

 pubescence ; it is very finely punctured, so that is it not at 

 all shining. The tibise are compressed in both sexes. 



The species is allied to A. Duboulayi, but it is much 

 smaller ; the basal portion of the antenna is not so slender, 

 the thickening at the extremity therefore not so abrupt. 

 The elongate abdominal setse of A. Deyrollei afford a
