Horn] OTIORHYNCHINI. 63 



This genus cannot by the above characters be referred to any other group, 

 established by Lacordaire, than the Otiorhynchides vrais, in which I can 

 find no genus with similarly formed antennal scrobes. The metasternal 

 side pieces although very narrow are distinct and have the suture plainly 

 visible in its entire length. 



This genus represents in our fauna Sciobim of South Africa. 



S. Qbscurus, n. sp. 



Form oval, body densely covered with luteous scales, elytra with darker 

 discal space limited behind by a very sinuous line. Head and rostrum 

 together very little longer than the thorax, the latter with an extremely 

 fine median carina, surface sparsely punctured. Thorax cylindrical, slightly 

 wider than long, sides feebly arcuate, apex and base truncate, surface 

 coarsely but sparsely punctured and with a shallow fovea on each side near 

 the base, scales dense, color luteous, fine median and broader lateral lines 

 paler. Elytra oval, very slightly attenuate behind, not wider at base than 

 thorax, one-third longer than wide, striate, striae punctured, intervals flat, 

 the middle with one, the other with two rows of very short hairs, surface 

 densely covered with luteous scales, with large irregular discal, darker 

 space limited behind by a very irregularly sinuous line. Body beneath 

 sparsely scaly. Legs densely scaly and sparsely hairy. Length .22-. 24 

 inch ; 5.5-6 mm. 



The style of coloration of this species nearly that of Cercopeus. It may 

 however, become entirely unicolorous. 



Occurs in California, Oregon and Vancouver. 



AGRONUS, n. g. 



Rostrum slightly longer than the head, and slightly narrower to tip, 

 cylindrical above, slightly flattened and with fine groove, tip truncate with 

 semicircular naked space. Scrobes superior, very short, cavernous, slightly 

 converging and terminal. Eyes small, round, moderately prominent. 

 Antennae long, sub-terminal, scape passing the anterior margin of thorax, 

 very gradually thicker to tip and feebly arcuate, funicle 7-jointed, first 

 two joints longer, joints 3-7 obconical and gradually shorter; club elongate 

 oval. Thorax cylindrical, base and apex truncate, sides very feebly 

 arcuate. Elytra oblong oval, not wider at base than thorax. Scutellum 

 wanting. Metasternum short, side pieces narrow, suture indistinct. Inter- 

 coxal process of abdomen short, broad, truncate, second segment longer 

 than each of the two following, separated from the first by an arcuate 

 suture. Cotyloid cavities of hind tibiae terminal, the margin simply fim- 

 briate with short spiuules and without terminal spurs. Tibiae not mucro- 

 nate. Claws small, free. 



This genus resembles the preceding in most of its characters, and differs 

 in the absence of spurs to the hind and the mucro to the anterior and mid- 

 dle tibiae ; the less distinct metasternal side pieces and the structure of the 

 second abdominal segment. Allied to Parameira by Seidlitz' table, differs 

 in its shorter scrobe and more slender antennae.
