Close to 2\ itiveo-rittatus, but differing in the colour of the 

 clothing; the prothoracic granule^ are also smaller and less con- 

 fluent, and the elytral interstices narrower, more raised and less 

 crenulate. 



Talaurinus posticalis, n. SJ). 



<? Elongate, narrow, size moderately large. Black, with muddy- 

 grey clothing in depressions, giving insect a dingy appearance. 

 Setae few, mostly absent from elytra, of a light l)rownish colour. 

 Beneath with a broad, golden-brown, liirsute vitta, extending the 

 length of abdomen. 



Head and rostrum in the same plane above ; forehead feebly 

 concave. Rostrum moderately long, deeply excavate, external ridges 

 with a light sinuation about middle, slightly thickened at base; 

 internal ridges short, little prominent, convergent but not meeting; 

 median area deeply depressed, sulciform posteriorly, widening out 

 in front; sublateral sulci short, not very dcej), running into depres- 

 sion at base of rostrum, behind the internal ridges. Scrobes simple, 

 ending far from eyes. Eyes ovate. Antennal scape moderately 

 long, rather strongly incrassate, slightly curved backwards. Pro- 

 thorax (4.5 X 4.5 mm.) subcylindrical, little rounded on sides; 

 apical margin lightly sinuate above, more deeply at sides; sub- 

 apical imjiression ill-defined, irregidar; disc with irregular depres- 

 sions and nodulose, irregular, confluent elevations, and more 

 definitely granule.? laterally; sides witli flattened granules. Elytra 

 (11 X 7 mm.) slightly wider at l)ase than prothorax, thence evenly 

 and gently rounded on sides; base lightly emarginate, hum<'ii 

 marked by thickened nodule. Disc with three broad foveolate sulci, 

 foveae extremely irregular and ill-defined, not marked off from each 

 other laterally, but separated at irregular intervals above and below 

 by irregular thickened ridges; the outer sulcus with foveae smaller. 

 more punctiform but still ill-defined. Interstices two, four and six 

 quite obsolete, the others costiform; first not elevated except at 

 bottom of declivity, where it is raised into a strong rounded ridge; 

 third interstice very prominent and costiform, .soniewhat flexuous 

 in outline, extending from base to halfway down declivity; fifth 

 somewhat less elevated, showing a slight tendency to break up into 

 its component granules, extending from humeral angle to edge of 

 declivity; seventh forming lateral boundary, costiform, less \n-o- 

 minent, also showing tendency to break up into granules. Sides 

 foveo-striate, foveae small, punctiform; interstices slightly elevated, 

 hardly costate, and not definitely granulate. Beneath with ventral
