Pitchy black, shining ; mandibles punctured like the 

 head ;* head excavated in front behind the clypeus, very 

 rugose at the sides, smooth in middle, with rather large 

 scattered punctures on the disc. Thorax transverse, 

 more finely punctured than the head, with two shallow 

 foveae on each side. The margin in front is smooth, at 

 the sides narrowly raised, reflexed at the posterior angle, 

 and continued round the base. The interstices of the 

 elytral striae are punctured like the thorax. 



I obtained two examples at Sapporo early in August, 

 1880, and one (dead) under a stone on Niohosan the 

 following year. From the numerous fragments I saw of 

 it amongst stored timber at Sapporo I concluded that it 

 must be common there in early summer. 



JEsalus Asiaticus, n. s. (PI. XIV., fig. 5). 



Ovalis, niger opacus rugose sculpturatus, squamis 

 brunneis plus minusve dense variegatus, niaculisque 

 tomentosis erectis nigris. Long. 2£ — 2f lin. 



Seven males, thirteen females. 



Oval, rather convex, opaque, very roughly sculptured, 

 and more or less clothed with brown scales. Beneath 

 the scales there is a surface with distinct, rather shallow 

 and somewhat irregular, punctures. Forehead depressed. 

 Thorax has a medial line free of scales or setae, and on 

 each side are two clumps of thick black setae, and above 

 the last an ill-defined crescent of the same. The elytra 

 have, including a sutural line, fine lines of black spinose 

 maculations, which give a clear tesselated appearance. 

 The sexual characters are the same as in M. scarabceoides 

 of Europe. 



This species is interesting as being a second species in 

 a remarkable genus. The individuals are considerably 

 smaller than those of scarabceoides, and the black 

 tomentum, forming well-marked separate spots or 

 patches on the elytra, give asiaticus quite a different 

 appearance. Not knowing the genus Msalus when I first 

 took the species, I thought it was one of the Colydiidce. 



This little species occurs in large forests of considerable 

 elevation. I obtained it first in May, 1880, above Miyano- 

 shita. I took off bark from a fallen tree which was 



* Each mandible is as long as the head, reflexed, with two 

 teeth, one basal the other ante-medial, and in this respect is 

 nearer the American striatus than the European tenebrioides.
