humeral angle, and the bands are not interrupted at the suture, 

 the elytral striai are less distinct, and the hind tibise of the male 

 are straight and not swollen externally. In N. A-punctatus the 

 trochanter is simply bifid, but in iV. latifasciatus the internal 

 spine is obtuse and hamate. I have tour examples of this 

 species, and in all the mesosternum is thickly clothed with a 

 golden pubescence. Three of them are males, and one, which 

 1 think is of the other sex, has the trochanter simply bifid ; but 

 1 am not sure about this, as the head is not enlarged behind 

 the eyes and the clypeus has a small triangular red membra- 

 nous space, which may be a character of an undeveloped 

 male. 



Found at Sapporo and on Mount Niohozan.

Necrophorus mortuorum, Fabr. Ent. Syst. i. p. 248. 



Three examples were taken at Nikko and two at Sapporo. 

 It occurs also in Europe, Asia, and North America.

N. humatori Bimilis, at paulo minor ; pedibus gracilibus ; antenna- 

 rum clava nigra. L. 15-19 mill. 



The sculpture of this species is very similar to that of iY. 

 humatoi', Fabr. ; but the club of the antennee is black and more 

 lax, and the frontal sulci are more arched at the sides and 

 much less widened out before the neck. The legs and anteunse 

 are more slender, but I see no other differences. 



I saw it in plenty on JSIantaizan, August 20th, 1881, but 

 most of the specimens were drowned in a tub containing 

 rotten fish left by pilgrims, and only three good ones were 

 secured.

Found in all the islands.

The synonymy of this species is first given in the '■ Ento- 

 mologist,' Oct. 1887. It is not unfrequent near Pekin, and I 

 have taken it at Kiu Kiang, on the Yangtsze Kiang. I have 

 only one Japanese specimen.
