64 Mr. G. Lewis on Erotylidge yro?n Japan. 



The prosternal striae are turned inwards anteriorly, but are 

 not hamate, and are widely separate. 

 Taken in Higo. 



Cyrtotriplax nigrojpunctata. 



Ovata, nigra, nitida, punctata ; ore, antennarum funiculo tarsisque 

 piceis; elytris rufis, apice, punctis regioneque scutellari nigris. 

 L. ^ mill. 



Black ; head rather more coarsely punctured than thorax ; 

 elytra red, with a large semicircular spot round the scutellum 

 and two small spots transversely placed to each other before 

 the middle of each elytron, one on the elytral edge, the other 

 on the fifth and sixth strife, black ; the apices of the elytra 

 for about one third of their length are also black, the pattern 

 ending in two semicircular edges, divided into two parts at 

 the fifth stria. The prosternal striee curve inwards anteriorly, 

 but are widely separate from each other. 



I took this at Miyanoshita in May 1880. 



Cyrtotriplax pallidiventris. 

 Ovata, nigra, nitida, ore abdomiueque rufo-testaceis. L. 4 mill. 



Ovate, black and shining ; head and thorax rather thickly 

 punctured, and seen under the microscope to be minutely 

 strigose ; base of the head obscurely pitchy red ; the elytra 

 very distinctly punctate-striate, with the interstices nearly 

 smooth ; the legs are rather robust. Beneath, the pro- and 

 mesosternum are rugosely punctate, the fourth posterior seg- 

 ment of the abdomen reddish yellow ; the prosternal lines 

 continue narrowly round the base, and gradually approach 

 each other anteriorly, but owing to the rugose surface it is 

 difficult to see whether they meet or not. 



I ca])tured three examples near the waterfall at Chiuzenji, 

 Aug. 22, 1881. 



Cyrtotriplax cenchris. 



Late ovata, rufa ; elytris apice infuscatis, antice nigro 4-maculatis. 

 L. 2|-3 mill. 



' Bather broadly ovate, red ; head punctate, thoracic punc- 

 tures finer and more scattered ; elytra wholly punctate, the 

 striae being indistinct owing to a similar sculpture of the 

 interstices ; each elytron has two black spots (smaller and 

 larger in different specimens), one below the humeral angle, 

 with the second posterior to it, the apex being infuscate, as 

 though a third spot were obsolete ; round the two black spots 

 the colour is sometimes yellowish, giving a tricolour appear-
