514 ME. GUT A. K. MARSHALL ON COLEOPTEEA 



of Avhich are blackish, enclosing a much smaller concentric blackish semicircular line; 

 the under surface with uniform brownish grey scaling, except on the 3rd and 4th 

 ventral segments which are bare and shiny, with small triangular lateral patches of 

 scaling. 



Bead finely shagreened and with shallow punctation Avhich is hidden by the 

 dense scaling, the forehead a trifle broader than the space between the antennse 

 and with a central fovea. Eostrum very long and slender, only a little shorter 

 than the front femur, cylindrical, and slightly wider at the base and apex; the 

 upper surface with irregular rows of very shallow large confluent punctures, the 

 intervals with numerous similar small punctures ; the under surface with deep 

 separated punctures, leaving two broad impunctate stripes. Antennas elongate, with 

 joints 3 to 5 about as long as broad, 6 longer than broad. Prothorax broader than 

 lono-, the sides slightly and roundly narrowed from the base to near the apex, and 

 there rather abruptly constricted and parallel-sided, the base shallowly bisinuate, 

 the median projection subemarginate, the dorsal apical margin truncate, the ocular 

 lobes moderately prominent ; the upper surface slightly rugose, fairly closely and 

 evenly set with small low shiny granules, except along an ill-defined central line, 

 the sculpture of the intervening spaces hidden by the scaling. Scutellum trapezoidal, 

 broadest behind, densely squamose. Elytra distinctly broader than the prothorax 

 at the shoulders, which are roundly rectangular, the sides parallel to beyond the 

 middle, thence roundly narrowed and constricted before the apex, which is jointly 

 rounded, the dorsal outline moderately convex, deepest before the middle, the 

 posterior declivity long and gradual; the sulci rather shallow, the contained punctures 

 hidden by the scaling, the intervals costate, the alternate ones slightly higher and 

 all bearing a row of shiny granules, except in the subapical patch, in which the 

 intervals are flattened and without granules, save for an inconspicuous xow on the 

 first interval ; the granules are more sparse at the base of interval 4, and they are 

 absent at the base of interval 2 and at the apex of 10 and 11 ; interval 9 more 

 strongly elevated near the apex; the scaling is recumbent and somewhat amorphous, 

 except on the posterior patch where the scales are distinct and more or less erect. 

 Legs long and slender, with dense brown and grey scaling and with scattered small 

 flattened granules, the front tibiae scarcely compressed, the tooth on the hind femorp 

 much larger than the others. Metasterimm sparsely granulate. 

 Length 12-13, width 4|-5, rostrum 5|— 5| mm.
