1889. ] INSECTS FROM MOUNT KINIBALU. 387 
XENOLOBA, nov. gen. 
Genus inter subfam. Gymnetinee ef Macronotinze collocandum. 
Corpus postice gradatim angustatum, supra deplanatum, velutino- 
opacum. Clypeus antice sensim dilatatus, apice medio anguste 
sinuato angulisque late rotundatis ; fronte medio obtuse earinata. 
Antenne clava valde elongata. Palpi elongati, gracillimi. 
Thorax trapezoideus, sed ad basin elytris multo angustior mar- 
gineque laterali ante basin breviter sinuato: supra equalis 
disco postice vix lineatim impresso, lobo basali magno postice 
vie angustato apiceque late rotundato. Scutellum mediocre, apice 
acutum. Flytra sicut in Macronotis ad humeros dilatata deinde 
usque ad apicem angustata abdominisque latera haud tegentia. 
Processus sternalis sat elongaius, paullo oblique dependens, sub- 
compressus, apice superiore paulo acuto. Tibie antice acute 
tridentate, postice extus leves apice longe bispinose. 
The very beautiful Cetonid which constitutes this genus connects 
in some measure the two large groups Gymnetine and Macronotine. 
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 fulvis plaga magna communi 
trilobata (utrinque albo trimaculata) fere nigra: capite antice 
flavo-metallico glabro grosse punctato, postice viridi-velutino, 
vittis duabus flavo-tomentosis : thorace sparse setifero-punctato 
immarginato, sed lateribus antice intra marginem depressiusculis 
et flavo-tomentosis : elytris utrinque haud profunde bisulcatis, 
sulcis interiore tri- exteriore subtiliter bi-striatis striaque simili 
suturali, alteris 2-3 propinquis, versus apicem. Pygidium longe 
erecte pilosum, nigrum, opacum, utrinque macula magna ochracea. 
Pedes fulvo-testacei, eneo-tincti. Subtus viridi-velutina, erecte 
Sulvo-pilosa, abdomine utrinque fasciis 4, metasterno fasciis 2, 
episternis anterivribus et maculis variis, ochraceis. Long. 18 
millim. 
Two examples. 
CHALCOTHEA (PLECTRONE) AURIPES, Westw. Tr. Ent. Soc. 1874, 
p- 474, t. vil. fig. 2 (2 ); Ritsema, Midden-Sumatra, Col. t. ii. figs. 6, 
64', 6c, 6a’, Ge’ (2). 
3. A femina differt solum tibiis anticis angustis extus inermibus, 
intermediis intus medio incurvatis, posticis intus usque post 
medium dilatatis, ibique subito angustatis et lobo acutissimo 
unciformi armatis ; ventro 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.
