the sides evenly rounded and the hind angles obtuse. The 

 elytra are finely striate, with the intervals flat and closely 

 longitudinally rugose. The shoulders are sharp and the sides 

 rounded. The mentum is very coarsely rugosely punctured. 

 The lower surface of the body is shmmg but strongly punctured, 

 the last abdominal sternite very coarsely and closely. 



(J. The l)ody is depressed and rather parallel-sided, the head 

 more or less hollowed in front, with the hinder edge of the 

 excavation a little produced, except in very small specimens. 

 The clypeal process is bilobed. The sides of the head, except 

 in very small specimens, are promment behmd the ej^es. The 

 sides of the jn-onotum are rather straight and parallel, with the 

 front angles obliqueh^ truncate or bluntly j^roduced, the hind 

 angles distinct but obtuse. The elijtra are flneh' and deeply 

 striate, except at the sides, where they are tuiely and closely 

 punctured and rather dilated. The shoulders are sliarply 

 ungulate and the sides rounded. The metasternum is strongly 

 punctured, the abdomen almost smooth, except upon the last 

 sternite, which is very closely punctured and setose. 



Variation of the male. As in jEgus chelifer, but in large males 

 the anterior process of the head is rather more produced and 

 the mandibles are rather broader, flatter and less slender.
