62 Mr. G. Lewis on Erotylidge/row Japan. 



broad posteriorly, narrowed at the coxse, the strise turn out- 

 wards at the coxge, nearly touching the sides of the thorax ; 

 the anterior edge of the prosternum is marginate. The antenna 

 have the two basal joints rather large, the third to eighth 

 small, and the club is compressed and oblong-ovate. 



I took an example at Miyanoshita and a second on Oyama 

 in May 1880, and both appear from the tarsi to be females. 



Neoiriplax palUdicincta. 



Ovata, obscure nigra, nitida ; elytris pallidicinctis ; antennis pedi- 

 busque infuscatis. L. &i mill. 



Head rather sparsely, evenly punctured, thorax with fine 

 punctures on the disk and before the scutellura, more coarsely 

 punctate on each side of base ; elytra punctate-striate, inter- 

 stices irregularly puncticulate, the outer edge rather broadly 

 yellow, the band being double the breadth at the humeral 

 angle^ where it includes the fifth stria, and the band widens 

 again before the apex ; the abdomen is pitchy brown. 



This and the preceding species, if the males are known to 

 me, are without the conspicuously dilated tarsi seen in N. atrata 

 and Lewisii\ but I do not consider the material at hand 

 sufficient to decide the question. The prosternum is formed 

 on the same plan in the four species. 



Fukushima, two specimens, July 1881, also probably 

 females. 



Cyrtotriplax sohrina. 



C consohrince proxime affinis, sed paulo major ; nigra, nitida ; 

 antennis pedibusque nigris; elytrorum macula sanguinea tripartita. 

 L. 4|-5 miU. 



This is the Japanese representative of G. consohrina and bi- 

 j)ustulata. The punctuation is the same, but the red elytral 

 fascia is divided into three parts; a broad sinuate band, 

 touching the outer edge, extends inwards to the second stria, 

 leaving the suture black, and then passes upwards to the base 

 of each elytron, occupying the space of the interstices between 

 the third and fifth striaj. The legs and tarsi are longer, and 

 the tibiaj, especially the middle pair, more dilated. The 

 prosternal strige are hamate anteriorly, and terminate at a 

 point distant from one another. In C. consohrina the pro- 

 sternal strige tend throughout their length to converge, and do 

 nearly meet in front. 



Cyrtotriplax centralis. 

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