Mr. Whitehead obtained female examples only, ia which the 

 mesfisternal process is extremely short and far from semicircular as 

 desiTibed hy Vollenhoveii. I have, however, seen another example 

 ( $ ), from Bornt-o (probably Sariuvak), differing in no other respect 

 from these two than in the mesosternal process being nearly seini- 

 circula:-. The sides of the thorax are immarjinate.

Chalcothea pomacea. 



$ . C. respleudenti quonrl formam shnilis, paullo rohustior, toto 

 pomnceo-viridis suhargenteo-relucens, subtus medio tantum sub- 

 flacescens, t arsis clutlybeis ; supra medio fere a col to usque apicem, 

 tatius et profundius quam in C. respleiidente concava ; supra et 

 subtus /fevissima, capite ihomcisque laterihus parce punctatis, 

 elytrisque prope m'irginem et apicem plagis duabus strigosis.eallo 

 humerali valde conveoco nigra, callo apieali parnm elevato : capite 

 elongato, angusto, autice parum dilatato, apice triangular iter fisso : 

 thorace elongato et angusto, ante medium perparum et hand angu- 

 latim dilatato, postice minus oblique sinuato-dilatato, angulis 

 posticis perparum. extus productis, margine laterali integro . 

 Processus mesosternalis brevis, rotundato-subacuminatus vet semi- 

 ovatus. Fentris segmentum apicale apice medio obtuse rotund- 

 atum, stricjulatum et setif'ero-punctaium. Tibia posticcB calcari 

 interiore apice oblique truncato. Long. 30 millim. 

 A single female example. May possibly be found to belong to 

 the section Plectrone when the male is known. The margined sides 

 of the thorax would bring it, like the following, within the definition 

 of Ritsema's genus Pseudoclialcothea, which appears to be synonymous 

 with Plectrone, all the species of which that I have seen have the 

 thorax similarly margined. 



Chalcothea planiuscula. 



$ . Dilutius pomaceo-viridis, submetallico-nitens, capite viridi-ceneo, 

 antennis palpisque riijis, tibiis et tarsis fulvis Icete aureo- vel 

 cupreo-metallicis : capite ante oculos sat brevi, quadrato, apice 

 minus angulatim profunde emarginato, passim punctata ; thorace, 

 scutello et elytris medio lute et parum profunde depressis, his 

 longe ante apicem fere planis ; thorace anguste trapezoidali, angulis 

 posticis parum productis, lateribus paullulum flexuosis fere rectis, 

 sulco margintili profunda passim minutissime dense punctulato, 

 punctis paullo mnjoribus consperso, lobo basali minus praducto, 

 scutelloque elongato : elytris lateribus et apice sat dense punctatis, 

 disco utrinque canvexo Itsvi. Pygidium dense transversim striatum.
