and third joints short. Mentura very broad, concealing the 

 ligula. Ligula with short widely diverging lobes, the labial 

 palpi loii^, with the basal joint slender, the second short 

 and the third oval. Prosterniun scarcely elevated })(^hind 

 the froiit coxae, not compressed nor produced. Front tibia 

 with terminal fork and fairly numerous lateral teeth, the 

 middle and hind tibi;e usually with two or more small lateral 

 spines. Claws and puhMllus long. Scutelhnn short and trans- 

 verse. Elytra longitudinally striate, the dorsal striae six in 

 number. 



The mandibles of the female are simple, short and broad. 

 Tliose of the male are Umger but never extremely long, sim])ly 

 curved, often toothful but not branched. 



^(jKs is nearly related to Doitks, but is distinguished by the 

 completely divided eyes and usually by the occurrence of 

 several tine lateral s])ines upon each of tlie four posterior tibiae. 

 Another important distinction is found in tiie grooved elytra. 

 In Dorcus grooved el^-tra are rare and the grooves, when present, 

 are more numerous and less regular. 



A species referred to this genus as Mgns interrupt us was 

 described in a few words by Macleay as doubtfully Indian 

 (Macleay, Hone Entom. 1919, p. 113). The type, "if still in 

 existence, is in the Macleay Mu.seum in Sydney, N.S.W., and <as 

 it is impossible to identify the species it is best ignored.
