PI. xiii., fig. 6. 



Dark piceous-brown, elytra sometimes dark castaneous. 

 Some long straggling hairs on sides of protliorax and of 

 elytra, and some shorter ones on under-surface and legs. 



Head smooth, convex, and with sparse and minute punc- 

 tures. Rostrum about twice as long as its apical width; 

 with rather sparse and small but distinct punctures, becoming 

 more numerous about apex. Prothorax with sides evenly 

 rounded and gently increasing in width from apex to about 

 basal fourth, and then decreasing to base; with sharply 

 defined, fairly large and numerous but not crowded punctures 

 on upper-surface, denser and larger on sides. Elytra at base 

 wider than base of prothorax, shoulders strongly rounded, 

 sides gently rounded and widest at about middle; with rows 

 of large, regular punctures, in rather deep striae; interstices 

 evenly convex, and each with a row of minute punctures. 

 Sterna and two basal segments of abdomen with coarse punc- 

 tures, smaller and more crowded on apical segment, and 

 absent from the third and fourth. Length (excluding 

 rostrum), 2'75-3'25 mm.

 Type, I. 15304. 



Some specimens are almost uniformly coloured through- 

 out, but on others the- elytra, club, and sometimes parts of 

 the legs are slightly paler. On the male there is a wide 

 shallow depression on the two basal segments of abdomen, 

 on the female those segments are flat in the middle. All 

 the specimens were obtained at the roots of beach-growing 

 plants.
