240 Mr. H. W. Bates' supplement to the 



angustato, angulis posticis obtusis subrotundatis, fovea 

 utrinque basali oblonga parce punctata, marginibus 

 lateralibus rufescentibus ; elytris apice parum oblique 

 sinuatis, acute subpunctulatim striatis, interstitiis sub- 

 planis, tertio impunctato. Long. 7g- mm., $ , ? . 



Yokohama, on the beach ; common in March at Hon- 

 moku. 



It is with great hesitation I venture to describe this 

 species as new ; it approaches so closely several of the 

 smaller European species, with all of which I have been 

 able to compare it, except with H. flavicornis . The form 

 of the thorax, however, seems to be different from that 

 of all the species alluded to, the sides being arcuated, 

 without trace of straightening towards the hind angles, 

 and the curvature being notably strong from the middle 

 to the anterior angles.
