X. — On Tivo neio SiJecies of the Genus Enoplotrupes, Lucas. 

 By the Hon. Walter Rothschild and Dr. K. Jordan. 



The species of Enoplotrupes^ Lucas (Bull. Soc. Ent. Fr. (4) 

 ix. 1869, p. xiii, redescribed and figured Ann. Soc. Ent. Fr. 

 (5) ii. 1872, p. 288), a genus of Geotrupidce remarkable for the 

 development of a horn more or less long in the middle of the 

 head and a bifurcate one in the middle of the prothorax in 

 the males, are found, so far as we are aware, only in the 

 south-eastern parts of Asia. E. sinensis, Luc. [1. c), from 

 Szechuen and Mupin, was the first- known species, of which 

 we have specimens from Chang Yang, taken in May at 

 elevations of 4000-6000 feet. The Western Chinese and 

 Eastern Tibetan countries have provided us with three more 

 species — E. Potanrni, Semenow (Hor^ Soc. Ent. Ross. 

 t. xxiii. 1889, p. 401), from Gan-ssu ; E. Largeteaui, Ober- 

 thur (Coleopt. Novit. 1883, p. 58) ; and E. Bieti, Oberth. 

 {ihid. p. 56, described as a Oynophtrupes)^ from Ta-tsin-lu. 

 Besides these forms one has been described from Yunnan 

 [E. yunnanus,Yo\xm. Ann. Soc. Ent. Belg. t. xxxii. 1888, 

 p. 17), two from Kiang-si {E. Cliaslii, Fairm., and E. varii- 

 color, Fairm., Ann. Soc. Ent. Fr. (6) vi. 1886, pp. 320 and 

 321), and one from Upper Burmah (Bhamo) [E. burmanicus, 

 Gestro, Ann. Mus. Civ. Genoy. (2) vi. 1888, p. 111). We 

 are able to add two new species, one from Assam and the 

 other from Siam.
