1889.] INSECTS FROM MOUNT KINIBALU. 387 



Xenoloba, nov. gen. 

 Genus inter subfam. Gymnetinse et Macronotinse coUocandum. 

 Corpus postice gradatim cmgustatitm, supra deplanatum, velutino- 

 opacum. C'lypeus antice sensim dilatatus, apice medio anguste 

 sinuato angulisque late rotundatis ; f route medio obtuse carinata. 

 Antennce clava valde elongata. Palpi elongati, gracillimi. 

 Thorax trapezoideus, sed ad basin elytris nntlto angustior mar- 

 gineque laterali ante basin breviter sinuato : supra eequalis 

 disco postice vix lineatim impresso, lobe basali magno postice 

 vix angustato apiceque late rotundato. Scitte'lum mediocre, apice 

 acutum. Elytra sicut in jNIacrouotis ad humeros dilatata deinde 

 usque ad apicem angustata abdominisque latera hand tegentia. 

 Processus sternalis sat elongalus, paullo oblique dependens, sub- 

 compressus, apice superiore paulo acuta. Tibice anticce acute 

 tridentatte, posticee extus laves apice longe bispinosce. 

 The very beautiful Cetonid which constitutes this genus connects 



in some measure the two large groups GymnetincB and Macronotince. 



The thorax is nearly evenly convex, and its posterior lobe and its 



relations to the scutellum are not widely different from the same in 



the genus Desicasta. 



Xenoloba speciosa. 



Saturate viridis, sericeo-opaca, elytris fuTvis plaga magna communi 

 trilobuta {utrinque albo trimaculata) fere nigra: capite antice 



fiavo-metallico glubro grosse punctata, postice viridi-velutino, 

 vittis duabus Jiavo-iomentosis : thorace sparse setifero-punctato 

 immarginato, sed lateribus antice intra marginem depressiuscuUs 

 et flava-tomentosis : elytris utrinque haud profunde bisulcatis, 

 sulcis interiare tri- exteriore subtiliter bi-striatis striaque simili 

 suturali, alteris 2-3 propinquis, versus apicem. Pygidium lange 

 erecte pilosum, nigrum, opacum, utrinque macula magna ochracea. 

 Pedes fulvo-testacei, aneo-tincti. Subtus viridi-velutina, erecte 



fulvo-pilosa, abdomine utrinque fasciis 4, metasterno fasciis 2, 

 episternis anteriuribus et maculis variis, ochraceis. Long. 18 

 mil Urn. 

 Two examples. 



Chalcothea (Plectrone) auripes, Westw. Tr. Ent. Soc. 1 8/4, 

 p. 474, t. vii. fig. 2 ( 2 ); Ritsema, Midden-Sumatra, Col. t. ii. figs. 6, 

 Gb', 6c', Gd', 6/($). 



cJ . Afcemina differt solum tibiis anticis angustis extus inermibus, 



intermediis intus media incurvatis, posticis hitus usque post 



medium dilatatis, ibique subito angustatis et lobo acutissimo 



unciformi armatis ; ventra medio depresso, apice impunctato. 



The female only was known to Westwood and Ritsema. Our 



examples agree exactly with the characters given by the latter to 



distinguish the species' from C. virens, which was also apparently 



known only in the female. I find the inner spur of the hind tibia 



in the male only a little obtuse at the apex, not obtusely truncated as 



figured by Ritsema.
