l68 Mr. G. Lewis on the Pyrochroidaj of Japan. 



the Asian continent. Motschulsky's knowledge of Japan at 

 the time when the country had been opened to Europeans 

 but two years was necessarily small, and it is reasonable to 

 doubt whether he thought it a matter of much importance to 

 keep the Japanese species separate from those of Dauria. In 

 the map, Schrenck, Reisen &c. ii. 1860, Hakodate is spelt 

 " Khokodady " and placed in the north of Yezo, whereas it is 

 in the extreme south, close to Matzumai, which is inserted 

 in the chart correctly. 



The following is a list of the species referred to in this 

 paper : — 



Ischalia patagiata, Lewis. Schizotus rubricollis. 



Pyrocliroa vestiflua. auritus. 



— — laticollis. gibbifrons. 



brevitarsis. Dendroid.es niponensii. 



peculiaris. ocularis. 



•japonica, Heyden. 



atripennis. Pyrochroa rufula, Motsch. 



Ischalia patagiata.^ Lewis. 



Ischalia patagiata, Lewis, Ann. & Mag. Nat. Hist. 1879, iv. p. 463. 



Oblonga, depressa, nigra, parce albo-hirta; antennis pedibusque 

 obscure nigris ; elytris externe late luteo marginatis. L. 5-5^ 

 miU. 



Oblong, depressed^ black, with the elytra broadly margined 

 with yellow, the yellow band occupies half the width of 

 each elytron until just before the apex, when it is confined to 

 the dilated rim of the elytron. The head projects on each 

 side to receive the antennaj ; the eyes are rather coarsely 

 granulate, with the space behind rather shining, convex, and 

 sparsely punctured. The thorax is rather elevated behind 

 the neck, with distinct lateral margins, and there is a longi- 

 tudinal carina before the scutellum which occupies about one 

 third of the length of the thorax, on each side of the carina is 

 a transverse depression. The suture of the elytron is raised 

 and the humeral angle dilated, its outer ridge forming the 

 commencement of the elytral carina, which terminates just 

 before the apex, just beyond the point where the yellow 

 margin narrows. I do not see any sexual characters. 



In 1881 I obtained four specimens in Hiogo and two at the 

 foot of Miyasan, one of the original localities. 



The American species of this genus was described as 

 Eupleurida costata by Leconte in 1866 ; but Pascoe's Ischalia 

 indigacea from Borneo was published in 1860, and his generic 

 name has priority. Crotch first included Ischalia in the 

 Pyrochroidse.
