188 I August, 



those of the pygidium, the last has a small fovea on each side of the base ; the 

 prosternum, keel densely punctate like the pygidium, lateral stria gradually con- 

 verging from the base ; the mesosternum transverse and narrow, nearly straight 

 anteriorly, with a slightly bent, deep, punctate, transverse stria, metasternal suture 

 marked with a line of punctures ; the legs, anterior femora on the under-side densely 

 and coarsely punctate, the others smooth, anterior tibise 6-dentate, teeth near the 

 base small. 



The trivial name will call attention to the epipleural stria?. 



Sab. Nossibe Island, Madagascar.

 Hister succicola, Thorns., Skand. Col., iv, p. 22 i, 18G2. 

 Hah. This species is apparently commoner in Siberia than else- 

 where, but it is not considered a rare species in Western Europe. In 

 Japan I found it only at low elevations. 



Hister niponicus, sp. n. 



Suborhicularis, convexiusculus, 7iiger, nitidus ; stria frontali vix semi- 



circulari ; j)^''jnoto stria laterali itnica integra ; elytris striis suhcrenulatis 



1 — 3 integris, 4 ahhreviata rudimento aucta, 5 — 6 in medio ahhreviatis ; pro- 



irygidio pygidioque pariun dense punctatis ; prosterno distincte histriato. 



Long., 3 2 — 4j mm. 



This species is distinct from H. navus, Mars , 1854, in being 



broader, the breadth being especially noticeable in the width of the 



elytra below the shoulder, in the head being narrower, and the elytral 



stria; being distinctly crenulate. The prosternal stride are also much 



longer and more distinct. 



Sab. Japan. Found in all the islands ; it is equally common in 

 Tezo as in Kiushiu. Herr Eeitter has an example from the Amur 

 region. Sister navus, so far as I know, has only been taken in Syria.

 Sister I'^-striatus, Mars., Ann. France, 1873. 



After comparing a large number of specimens of Motschulsky's 

 species from Siberia and Japan with Sister 12-striafus, Schr. (14- 

 striatus, Gyll.), from Europe, I have come to the conclusion his species 

 is distinct. The lateral elytral fossa (subhumeral) in S. 5-striafus, 

 Motsch., is always deep and long ; in twelve examples before me from 

 Europe and North Africa the fossa is absent. The species is larger 

 and the sterna are perceptibly narrower, but above S. 5-sfriatus appears 

 in general outline to be broader than S. \i<-striatus, as Motschulsky 

 states. 



Sab. I found it commonly in all the parts of Japan I visited.
