[Vol.. Ill, 



dentatus, in the following characters only. Upper tooth of mandibles, usually weaker, 

 anterior lower tooth simple. Inner tubercles of Ä6'a(i perhaps a little more widely 

 separated ^ ; frontal area almost always about as long as broad, semilunar or almost 

 quadrangular in shape ; the two frontal ridges more or less evenly continuous with 

 one another and joined to central tubercle by a single sharply keeled ridge — not 

 curving round to meet in an acute angle close to apex of central tubercle as is usually 

 the case in L. dentatus. Scars of mesosternum dull, their surface evenly continuous 

 with a dull band extending along whole remaining length of outer margin. Lateral 

 areas of metasternum much broader behind than in front, about equal in their widest 

 part to minimum width of intermediate areas. Abdomen bordered beneath by a com- 

 plete broad band of fine but dense puncturing which includes the whole of the 

 terminal segment with the exception, in some specimens, of a small smooth spot near 

 the posterior margin. Depressed surface of two or three outermost grooves of elytra 

 dull, the sculpturing somewhat indistinct and worn-looking, especially at the ends; 

 the ninth and tenth ribs narrow throughout.
