Two specimens found by M, Vitalis de Salvaza arc all 

 that are yet known of this species. 



It is the largest of the genus known to me and is rather 

 less hemispherical in shape, with shorter antenna;, than its 

 congeners. It is, however, allied to JJ. loiv/icoruis, and has 

 closely similar markings. The pale fasciie are more dis- 

 tinctly interrupted at the suture and the inner black basal 

 spot is nearer to the shoulder than to the scutellum. The 

 ]iroaotum is relatively longer, more contracted in front, less 

 distinctly margined at tiie sides, with feebler basal fuveae. 

 The elytra arc less strongly and regularly punctured, and the 

 punctures are large and small intermixed. The last three 

 joints of the antenna form more than a third of its total 

 length and the two preceding joints are distinctly larger 

 than the three immediately before them.

This has a ratlier close resemblance to the Japanese 

 Ph(Eomychus rvfipennis, Mots., with which it is identical m size 

 and coloration, but differs in the absence of a stridulating 

 apparatus upon the head and of sexual difference in the 

 front tibiae. In actual relationship it appears to be nearest 

 to E. {Coenomychus) playiatus, Gorb., but it is a more stontly- 

 formed insect, with less slender legs and antennoc and 

 broader prothorax. The pronotum is exceedingly finely 

 and scantily punctured, distinctly margined at the sides, 

 with the front angles rounded and broadly hollowed out, 

 the hind angles acutely produced and the basal impressions 

 broad and deep. The elytra arc distinctly |)uncturc(l, a 

 little broader at the slioulders than the pronotum, and only 

 very little wider behind the middle.
