of the clypeus is not very distinct by itself, but is rendered 

 very distinct by the difference in the density of the punctures 

 before and behind it; there are about ten distinct striae on 

 each elytron, the punctures in each do not form a regular 

 row at the deepest part, but many are on the sloping parts, 

 although they could scarcely be regarded as geminately 

 arranged; each of them, when viewed from behind, appears 

 to have a small basal granule. The nine-jointed antennae 

 associate this species with laticollis and helaeoides, in Black- 

 burn's table, from which it may be distinguished by the longer 

 basal joint of the hind tarsi; the punctures of the head and 

 prothorax approach those of laticollis, but the elytral sculpture 

 is very different; the hind tarsi were not mentioned in the 

 description of laticollis, but two specimens (received from Mr. 

 Carter and taken by Judge Docker at Walgett, as was the 

 type) of that species before me have the basal joint decidedly 

 shorter and thicker than the second. 



Byrrhomorpha rudis, n. sp. 



Black; antennae, palpi, and parts of tarsi reddish. 

 Metasternum with fairly numerous blackish hairs, rest of 

 under-surface and legs sparsely clothed. 



Head with crowded but sharply-defined punctures of 

 moderate size. Clypeus widely excavated in front, sides rather 

 strongly elevated, hind suture in the form of a narrow carina; 

 punctures as between eyes, but becoming smaller on sides. 

 Labrum conspicuously elevated in front, deeply impressed 

 along middle, the impression continued on to mentum, but 

 much shallower there. Antennae nine-, club three-jointed. 

 Prothorax scarcely twice as wide as long, sides decreasing in 

 width from near base to apex, front angles rather strongly 

 produced and acute, hind ones somewhat obtuse; median line 

 rather feeble at base, but rather wide and deep in front; 

 punctures much as on head, but becoming smaller (although 

 not sparser) towards all margins. Scu tell urn with dense 

 punctures, but tip polished and impunctate. Elytra feebly 

 dilated to, beyond the middle, each obliquely truncate at apex; 

 striae deep and wide, with coarse, irregular punctures, the 

 interstices irregular, and with sharply-defined punctures. 

 Pygidium with crowded asperate punctures, and a distinct 

 median line. Front tibiae strongly tridentate. Length, 

 8-115 mm.

A rough-looking species close to verres, but club with 

 only three joints, prothorax with more crowded punctures,
