Show 1889.] INSECTS FROM MOUNT KINIBALU. 389 Pygidium apice planum. Ventris segmentum apicale apice obtuse rotundatum, strigosum. Long. 32 millim. CHALCOTHEA AFFINIS, Vollenh. Tijdschr. Nederl. Ent. Ver. i. p. 23, t. ii. fig. 2(3). Mr. Whitehead obtained female examples only, in which the mesosternal process is extremely short and far from semicircular as described hy \rollenhoven. I have, however, seen another example ( $ ) , from Borneo (probably Sarawak), differing in no other respect from these two than in the mesosternal process being nearly semicircular. The sides of the thorax are immaraiuate. -o CHALCOTHEA POMACEA. 2 • C. resplendenti quoad formam similis, paullo robustior, toto pomaceo-viridis subarc/enteo-relucens, subtus medio tantum sub-flavescens, tarsis chalybeis ; supra medio fere a collo usque apicem latius et profundius quam in C. resplendente concava. ; supra et subtus leevissima, capite thoracisque lateribus parce punctatis, elytrisque prope marginem et apicem plagis duabus strigosis, callo humerali valde convexo nigro, callo apicali parum elevato : capite elongato, angusto, antice parum dilatato, apice triangulariterfisso: thorace elongato et angusto, ante medium perparum et haud angu-latim dilatato, postice minus oblique sinuato-dilatato, angulis posticis perparum extus productis, margine laterali integro. Processus mesosternalis brevis, rotundato-subacuminatus vel semi-ovatus. Ventris segmentum apicale apice medio obtuse rotundatum, strigulatum et setifero-punctatum. Tibice posticee 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 Pseudochalcolhea, which appears to be synonymous with Plectrone, all the species of which that I have seen have the thorax similarly margined. CHALCOTHEA PLANIUSCULA. 2 . Dilutius pomaceo-viridis, submetallico-nitens, capite viridi-ceneo, antennis palpisque rufis, tibiis et tarsis fulvis Icete aureo- vel cupreo-metallicis: capite ante oculos sat brevi, quadrato, apice minus angulatim profunde emarginato, passim punctato ; thorace, scutello et elytris medio late et parum profunde depressis, his longe ante apicem fere planis ; thorace anguste trapezoidali, angulis posticis parum productis, lateribus paullulum flexuosis fere rectis, sulco marginali profundo passim minutissime dense punctulato, punctis paullo majoribus consperso, lobo basali minus producto, scutelloque elongato: elytris lateribus et apice sat dense punctatis, disco utrinque convexo leevi. Pygidium dense transversim striatum. Processus mesosternalis brevissimus, antice rotundatus. Subtus medio leevis, lateribus et pedibus disperse punctatis. Ventris PROC. ZOOL.
