Mr. G. Lewis on Erotylidge/rom Japan. 67 



rior segments of the latter are also red ; the prosternal pro- 

 cess is rather raised in front, and the stri^ resemble those of 

 C. niponensis. 



Three specimens, taken at Miyanoshita, May 1880. 



Cyrtotriplax tripartiaria. 

 Ovata, nigra, nitida, ore anteanisque piceo-rufis ; capite thoraceque 

 parum dense punctatis ; scutello rufo ; elytris antics rufls, 

 post ice nigris. L. 4 mill. 



Black, shining; thorax evenly and somewhat densely 

 punctate ; scutellum smooth and red ; elytra, base wholly 

 red, apex wholly black, each colour occupying about half the 

 elytral area ; behind the scutellum the black encroaches on 

 the red, at the fifth stria and outer edge the red encroaches on 

 the black. Beneath, the sides of the abdomen are broadly red, 

 also the tarsi ; the prosternal lines are anteriorly hamate. 



I possess four specimens from Higo. 



Cyrtotriplax basalts. 

 Breviter ovata, nigra, nitida; antennis pedibusque dilutioribus, capite 



basi rufo thoraceque parum dense punctatis ; scutello nigro ; 



elytris basalibus rufis, punctato-striatis, interstitiis obscure punc- 



ticulatis ; tibiis robustis. L. 3| mill. 



Black and shining ; head and thorax evenly and somewhat 

 densely punctured ; neck reddish ; elytra punctate-striate, 

 punctures rather fine, interstices very finely puncticulate ; the 

 region behind the scutellum is piceous to the breadth of one 

 interstice ; after the first stria a red band begins, which 

 widens out on the interstices on each side of the fifth stria 

 and touches the outer edge. Beneath, the elytral fold is red 

 at the humeral angle, and the anterior edge of the prosternum 

 is transversely obscure yellow ; the prosternum is minutely 

 rugosely strigose, the sculpture assuming the mosaic form on 

 the metasternum ; the prosternal lines are bent inward at their 

 apex. 



I swept one example of this very distinct species on Oyama, 

 May 24, 1880. 



The following species have black or blue black elytra and 

 the thorax wholly red or nearly so, and superficially appear 

 to be like an ordinary Triplax except in being convex : — 



Cyrtotriplax similis. 



Oblongo-ovata, rufa, nitida ; elytris nigris, punctato-striatis ; anten- 

 nis basi pedibusque rufis. L. 5 mill. 

 Red ; head and thorax sparsely and rather evenly punctured, 



the punctures at the base of the head being relatively large ; 



the scutellum is obscurely red, broadly margined at the sides 



with black : the elytra are somewhat finely punctate-striate,
