Two specimens, males. Separable from the Japanese E. macr- 

 oplifhalmus by the very finely striato-pimctate elytra, with flat interstices, 

 the minutely punctate prothorax, and the wholly black body. The 

 reddish-brown vestiture of the prothorax modifies its dark ground- 

 colour. 



HOLOSTROPHUS Hom. 



The species of this genus have the epimera and episterna of the 

 prothorax connate, the elytra confusedly punctate, the eyes small and 

 distant, the prosternal process long, and the posterior tibiae narrow 

 and unnotched on the upper edge. HolostropJms is represented in 

 North America, Japan {H. dux, orientalis, uiiicoJor, and 4!-ma.cnlaiiis 

 Lewis), Formosa {H. multinotatui^ Pic), Java (H. fruhstorferi Pic), 

 Borneo, etc.
