36 Hon. W. Rothschild and Dr. K. Jordan on 
X.—On Two new Species of the Genus Enoplotrupes, Lucas. 
By the Hon. WALTER RoruscuHILp and Dr. K. JORDAN. 
THE species of Hnoplotrupes, Lucas (Bull. Soc. Ent. Fr. (4) 
ix. 1869, p. xiii, redescribed and figured Ann. Soc. Ent. Fr. 
(5) li. 1872, p. 288), a genus of Geotrupide 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. . sinensis, Luc. (/. ¢.), 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—. Potanint, Semenow (Hore Soc. Ent. Ross. 
t. xxill. 1889, p. 401), from Gan-ssu; L. Largeteaut, Ober- 
thiir (Coleopt. Novit. 1883, p. 58); and #. Biet?, Oberth. 
(cbid. p. 56, described as a Gynoplotrupes), from Ta-tsin-lu. 
Besides these forms one has been described from Yunnan 
(E. yunnanus, Farm. Ann. Soc. Ent. Belg. t. xxxii. 1888, 
p. 17), two from Kiang-si (#. Chaslit, Fairm., and E. varii- 
color, Fairm., Ann. Soc. Ent. Fr. (6) vi. 1886, pp. 320 and 
321), and one from Upper Burmah (Bhamo) (. burmanicus, 
Gestro, Ann. Mus. Civ. Genov. (2) vi. 1888, p. 111). We 
are able to add two new species, one from Assam and the 
other from Siam.
