g [June, 



The ground-colour of the abdomen of this species is, especially on 

 the under-side, light sanguineous, this colour is, however, in some 

 degree concealed by the minute pale grannies spread over the surface. 

 The greatest convexity of the venter is between the fifth and sixth 

 segment. The last two articles of the antennae are, at least in the 

 described specimen, compressed. 



Aradus emarginatus, n. sp. 



Elongafo-suhovalis, opacuft, fusco-niger, rostro pedihusque Jlavo- 

 ajinulafis ; pronoto quadricarmato ; angulis posiicis segmentorum ohdo- 

 minalium prominentihus. Long. (^, 6.5 mon. 



Mas: hemelytris abdomine angustioribus, sed parum brevioribus ; segmentis 

 ventralibus quinto et sexto medio cum segmento genitali convexis ; segmento geni- 

 tal! ad dimidium apicalem rimse genitalis anguste luteo, lobis explanatis liujus 

 segmenti admodum reflexis, marginibus interioribus rectis, valde divergentibus, 

 exterioribus sub-angulato-rotundatis, ante apicem denticulis duobus minutissimis 

 armatis ; lobis lateralibus segmenti ultimi abdominis a lobis genitalibus distantibus. 



Femina igiiota. 



A. emarginatus, Rent, in sched. 



Patria: China (Peking). Coll. Fallou. 



Antecedenti abdominis structnra similis, sed cetera optime distinctus. Caput 

 pone oculos angustatum, ad basin denticulo rainuto lineari utrinque armatum, inter 

 oculos impressione U-formi prseditum ; antennis nigris, articulo primo brevi, secundo 

 hoc plus quam duplo longiore, sub-cylindrico, apice perpaullo incrassato, tertio 

 secundo paullo longiore, apicem versus parum attenuate (art. quartus deest) ; 

 processu apicali basin articuli secundi antennarum paullo superante ; spinis later- 

 alibus sat validis, acutiuseulis, divergentibus, medium articuli primi antennarum 

 superantibus, extus basi obsoletissirae unidenticulatis ; dente anteoculari distincto ; 

 rostro coxas anticas aliquantura superante, nigro, articulo penultimo et antepenultimo 

 apice flavido. Pronotum lateribus admodum rotundato-ampliatum et reflexum, 

 marginibus autico-lateralibus subserrato-denticulatis, ante medium angulariter emar- 

 ginatis et deinde sub-rectis, convergentibus, baud ampliato-reflexis, denticulis fere 

 destitutis ; disco quadricarinato, carinis interraediis sub-parallelis, mox ante medium 

 approximatis, carinis externis brevibus, medium pronoti baud superantibus ; angulis 

 posticis retrorsum obtuse productis, deflexis. Scutellum elongatulum, lateribus 

 elevatis, extrorsum levissime rotundatis, basin versus sub-parallelis. Abdomen sub- 

 ovatum, depressum, lateribus ob angulos posticos segmentorum abdominalium 

 prsesertim posteriorum admodum prominentes sub-serrato-emarginatis. Hemelytra 

 basi ultra marginem abdominis paullo ampliata ibique macula parva lutea (subtus 

 quoque distincta) ornata; corio area interna lineolis nonnullis luteis praedito ; mem- 

 brana obsolete sub-cinereo-interstincta. Pedes fusconigri, femoribus basi tibiisque 

 prope basin et apicem flavotestaceo-annulatis (annulo sub-basali tibiarum aegrius 

 distinguendo), geniculis anguste tarsisque flavopiceis. 



The discovery of these two species is of some interest, as no 

 species of the genus Aradus was hitherto known either from Japan or 

 China.
