which divides the smooth space from the punctate portion ; 

 the elytra are red, with a black spot, not well defined, at the 

 humeral angle, a second larger and formed as a band near the 

 middle, commencing in the interstice of the second and third 

 strias and touching the outer edge, a third, the size of the 

 humeral one, on the disk before the apex, covering the space 

 from the second to the fifth stria, the interstices are incon- 

 spicuously punctured and the scutellum is semicircular and 

 smooth. 



The smooth space before the scutellum has been given 

 as a generic character, and in the present insect the punc- 

 tures bordering it are obliterated posteriorly, which gives 

 an appearance as of a crenulate arch ; the sides of the thorax 

 are more deeply sulcate than in Microsternus Ulhei, Crotch. 



This very peculiar insect is unfortunately unique. It was 

 taken at Yuyama, in Higo, June 1881.
