.The two following species have slender tarsi and an inrer- 

 ociilar protuberance in the male : — 



" Pyrochroa japonica^ Heyd., ? . 



^'Pyrochroa japonica, Heyd., 5, Deutsche eut. Zeitschr. xxiii. 1879, 

 Heft ii. p. 354. 



" Depressa, obscure rufo-coccinea, antennis pedibusque nigris, ore, 

 thorace lateribus nigris, fronte nigra ; capita inter oculos fortiter 

 transverse elevato, antice laxe excavato. Thorace minore, parum 

 latiore quam longiore, lateribus post medium angulatis, ante 

 medium transverse late impresso, liuea media canalirailata in 

 foveam antescutellarem effundente. Elytris plus quadruplo 

 thorace longioribus, ante medium dilatatis, transverse densissime 

 rugosis, in utroque linese duse e rugis obliquis plumiforraibus 

 latioribus. Palporum articulis primo minuto rufo et secundo 

 quarto fpqualibus, tertio breviore et angustiore, quarto lateribus 

 parallelis, basi apiceque acuminatis. Antennae partim desunt, 

 articulis 1 et 3-6 longitudine sequalibus, primo basi attenuato, 

 3-6 sensim fortiter ramosis, fortius (jam in tertio) quam in P, 

 pectinicorni, cui affinis sed major. L. 11 mill." 



- The male of this species has the pectinate branches of the 

 antennge very long, and in joints six to nine the processes are 

 more than three times the length of the joint that bears them. 

 Between the eyes there is a large vertical protuberance, which 

 is connected with the forehead by a median ridge, which, 

 viewed sideways, is usually seen to come to a raised point 

 immediately behind the antennse ; but in several examples 

 this elevation is obsolete. In two specimens the vertical 

 protuberance examined from above is divided on its upper 

 surface into two lobes. Heyden only knew the female. 



I have a series of about thirty examples from Subashiri, 

 Kiga, and other places lying under Mount Fujisan, and also 

 a few from Nikko. 



Pyrochroa atripennis. 



Atra, opaca ; capite antice palpisque flavis ; thorace rufo. L. 11 

 miU. 



Black ; head between the antennge and the mouth-organs, 

 except the tips of the mandibles^ flavous. In the male there 

 is a broad flattish protuberance on the head, which has its 

 base between the eyes, and, projecting forwards, is somewhat 

 truncate anteriorly and rounded off on each side, with two 

 Impressions on the upper surface, which leave the margins 

 and a median division raised. Thorax red, sometimes a little 

 transverse, with a cinereous pile and two lateral impressions
