386 MR. H. W. BATES ON NEW COLEOPTEROUS [June 18, 
profunde concavo, fronte carina lata obtusa antice declive et postice 
verticaliter truncata: thorace punctis umbilicatis annuliformibus 
medio distantibus, lateribus densis et subconfluentibus, linea dor- 
sali areaque basali impunctatis : scutello subtilissime striguloso- 
punetulato: elytris planatis, paullo subtilius quam thorace 
annulato-punctatis, lateribus post medium apiceque dense strigu- 
losis : pygidium strigis concentricis densissime impressum, erecte 
fulvo-pilosum: corpore subtus pedibusque (lateribus densius) 
fulvo-pilosis. Long. 26 millim. 
Although the female only is in the collection and of that a single 
example, the differences in colour and sculpture from the same sex 
in P. vollenhoveni seem to indicate a distinct species and to justify 
its description as such. 
MycrertsteEs (THEODOSIA) TELIFER. 
Elongato-oblongus, aurescenti-viridis, elytris planatis flavescentibus. 
3. Caput et thorax passim densissime confluenter punctulata sub- 
opaca, hoc dorso subnitens punctulis subdiseretis ; scutello et elytris, 
pygidio, corpore subtus et pedibus subtilissime dense punctulatis, 
sericeo-nitentibus : capite cornu sat brevi curvato, apice profunde 
bifido parum dilatato, frontis margine supra antennarum basin 
angulatim producto; thorace dorso oblique valde elevato et in 
cornu porrectum elongatum robustum apice emarginatum (sub- 
bifidum) producto ; cornu dimidio apicali fronteque igneo-cupreis : 
pedibus anticis, precipue tarsis, valde elongatis, tibiis extus 
acute et breviter bidentatis (apicali incluso), tarsis glabris. 
Q. Caput densissime ruguloso-punctatum, clypeo sparsim grosse 
punctato, margine ante oculum indentato deinde antice ficxuoso, 
clypeo angustato apice bidentato: thorace disco sparsim grosse 
umbilicato-punctato inter puncta subtilissime punctulato, late- 
ribus densissime rugoso-punctato: scutello punctis nonnullis 
grossis: elytris punctis umbilicatis, versus basin seriatis, versus 
latera et postice densius vel confusis: pygidio concentricaliter 
dense strigoso : tibiis anticis tridentatis. Long. 20-28 millim. 
According to the practice of recent systematists a new genus should 
be instituted for this species on account of the peculiar shape of the 
horns in the male; but the abrupt modifications in these features 
presented in the known species allied to Mycteristes seem to show 
that they form specifie and not generic characters, just as they do 
in such genera as Onthophagus, Phaneus, and Copris. Of the 
numerous genera proposed, the present species approaches nearest to 
Theodosia, Thoms. 
CoRYPHOCERA BORNEENSIS, Wall. Tr. Ent. Soc. (3) iv. p. 528, 
t. x1. f 22 
One (male) example, which I refer to this species on account of its 
perfect agreement, in form and colour, with Wallace’s description and 
figure. From the armature of the head of the male the species belongs 
undoubtedly to the genus Coryphocera and not to Diceros, as Mohnike 
supposed would be found to be the case when the male was known.
