 1 S. 



Much larger than rerrnrafus, lateral carina of pnithorax loii^pr, patch of 

 elytra larger, extending to scntelhiin, tnliercle of third interspace before middle. 



T."). Piezocorynus dorsalis spec. uov. 

 ?. Black, s]iii:ht]_v irrorated witli whitish grey ahove, denser grey beneath. 

 A lateral antemedian dot on jironotum and the scntelliim white ; a large patch 

 on elytra ochraceous cla}', expanded between the fifth strij)es of punctures, elongate- 

 elliptical, rounded in front and behind, slightly sinuate laterally in middle, not 

 reaching base, extending to apical declivity, faintly dotted with ochraceous in first 

 and third interspaces ; tibiae grey, with two large IJack patches on npperside, 

 first tarsal segment grey in basal half or two-thirds. 



Antenna slender, brown, segments 1 to 8 rafesceut at tip, 8 sleuder, slightly 

 dilated, obtuse at end, club loose, 9 one-fourth longer than broad, triangular, 

 truncate, 19 also triangnlar and truncate, about as broad as long, 11 pale, ovate, 

 distinctly longer than broad, truncate at tip. Pronotum very slightly uneven, 

 carina nearly basal in middle, angle acute, lateral carina not extending beyond 

 middle, gradually fading away. Scutellnm longer than l)road. Elytra somewhat 

 flattened from suture to fourth interspace, transversely depressed before middle, 

 subbasal convexity broad, even. 



Length, 3 J mm.

TO. Piezocorynus homoeus spec. nov. 



c?. In colour almost exactly the same as P. alternavs, in structure agreeing 

 closely with /daqifer, differing from alteriians in the much broader and apically 

 sinnate antennal segment 8, in the shorter and basally broader segment 8, in 

 tlie rectangular (slightly obtuse) bent of the pronotal carina, the rufescent elytra, 

 on which the black spots of altcrnans are replaced by brown ones and the darker 

 third and fourth tarsal segments. From plagifer the present species is distin- 

 guished, besides the pattern of the elytra, by the thinner antenna, of which the 

 last segment is luteous, the eveuly convex disc of the pronotum, the more straight 

 dorsal carina and shorter lateral one, and the less prominent subbasal callosity 

 of the elytrnm.

The second carina of the pronotum is not parallel with the first (anterior) 

 one, but is fused with it close to the lateral angle, forming with the short lateral 

 basal longitudinal carina and the anterior carina a small triangle. 



77. Piezocorynus alternans spec. nov. 

 c? ? . In colour similar to gracilicornis. Some spots between the eyes and 

 some on pronotum clayish ochraceous ; alternate interspaces of elytra tesselated 

 with black and clayish ochraceous ; pronotum indistinctly marmorated with black ; 

 antenna (except segments 9 and 10, which are brown), apex of femora, base and 

 apex of tibiae, base of first and second tarsal segments and the whole third and 

 fourth rnfous.
