APPENDIX. 
belongs undoubtedly to tbe genus Coryphocera and not to Diceros, as Mohnike supposed would be found 
to be tbe case when the male was known. 
Xenoloba, nov. gen. 
Genus inter subfam. Gymnetince et Macronotince collocandum. Corpus postice gradatim angustatum, 
supra deplanatum, velutino-opacum. Clypeus antice sensim dilatatus, apice medio anguste 
sinuato angulisque late rotundatis ; fronte medio obtuse carinata. Antennae clava valde elongata. 
Palpi elongati, gracillimi. Thorax trapezoideus, sed ad basin elytris multo angustior margineque 
laterali ante basin breviter sinuato : supra aequalis disco postice vix lineatim impresso, lobo 
basali magno postice vix angustato apiceque late rotundato. Scutellum mediocre, apice acutum. 
Elytra sicut in Macronotis ad humeros dilatata deinde usque ad apicem angustata abdominisque 
latera haud tegentia. Processus sternalis sat elongatus, paullo oblique dependens, subcom- 
pressus, apice superiore paulo acuto. Tibiae anticae acute tridentatae, posticae extus laeves apice 
longe bispinosse. 
The very beautiful Cetonid which constitutes this genus connects in some measure the two large 
groups Gymnetince 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 fulvis plaga magna communi trilobata (utrinque albo trimacu- 
lata) fere nigra : capite antice flavo-metallico glabro grosse punctato, postice viridi-velutino, 
vittis duabus flavo-tomentosis : tliorace 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 2-8 
propinquis, versus apicem. Pygidium longe erecte pilosum, nigrum, opacum, utrinque macula 
magna ochracea. Pedes fulvo-testacei, seneo-tincti. Subtus viridi-velntina, erecte fulvo- 
pilosa, abdomine utrinque fasciis 4, metasterno fasciis 2, episternis anterioribus et maculis variis, 
ochraceis. Long. 18 millim. 
Chalcothea (Plectrone) atjripes, Westw. Tr. Ent. Soc. 1874, p. 474, t. vii. fig. 2 ( ? ); Ritsema, 
Midden-Sumatra, Col. t. ii. figs. 6, 6b', 6c r , 6cl’, 6e' (<j>). 
$. A foemina 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. 
Chalcothea (Plectrone) viridipes. 
P. auripedi quoad formam simillima. Supra cum antennis et palpis saturate viridis submetallica, 
subtus pedibusque subseneo-viridis: clypeo profunde fisso, capite utrinque marginato et punc¬ 
tato : thorace lateribus punctatis et marginatis ante medium perparum angulatis deinde usque 
ad angulos posticos acutis fere rectis, medio cum scutello et elytrorum sutura late depresso : 
elytris prope marginem et apicem punctulatis sub callo apicali strigulosis. Processus meso- 
sternalis sequilatera 1 i-triangu laris. 
G . Tibiae anticae graciles, extus inermes ; posticae intus longe ante medium lobum elongatum tenuem 
apice triangulariter spathulatum emittentes. Yentris segmentum apicale apice medio emargi- 
natum. Pygidium transversim striatulum, apice convexum et medio sulcatum. 
? . Tibiae anticae latae, tridentatae ; postice inermes, calcari interiore elongato apice emarginato. 
Yentris segmentum apicale semicirculare, toto transversim striolatum. Pygidium striatum, 
apice parum convexum, aequale. Long. 84 millim. 
This species is similar in colour to Clerota brama (Gestro), to which I should have been inclined to 
refer it, if the mesosternal process had not been so different in form. In C. brama it is prolonged (as 
figured in ‘ Midden-Sumatra/ iv. 6, pi. ii. fig. 5 b~) into an acute point; in C. viridipes it forms a rather 
short subequilateral triangle. The hind legs and tarsi, judging from the figure, are also much shorter in 
C. brama than in C. viridipes.
