glabris. Thorax capite multo latior, quadratus, angulis anticis obtusissimis posticis rectis, 
lateribus explanato-reflexis, ante medium perparum rotundatis et postice leviter sinuatis. Elytra 
tborace plusquam duplo latiora, oblongo-ovata, basi utrinque emarginata, bumeris acutis et mox 
pone bumeros rotundato-dilatatis deinde margine sat explanato, prope apicem valde emarginato, 
ibiqne epipleuris margine inferiore sicut in Pterostichince, Ctenodactylince et Ilexagoniince inter- 
rupto. Tibine pluricarinate. Tarsi breves, maxime dilatati, subtus dense breviter pilosi, 
articulo l mo magno triangulari angulis rotundatis, 2 ndo breviore, paullo latiore angulis acutis, 
3 io multo angustiore, brevissimo, 4 fco iterum latiore, triangulari baud bilobato. Ungues sim- 
plices. Metatboracis episterna elongata, angusta. 
Dinopelma plantigradum. 
Nigrum politissimum, elytris vix asnescentibus ; capite laevi, epistomate 4-foveato ; thorace impunc- 
tato, foveis basalibus prope angulos posticos latis sat profundis, sulculo abbreviato intra marginem 
lateralem ; elytris paullo convexis, striis acutis et crenulatis utrinque novem aequaliter distantibus 
et impressis, interstitiis planis, 3 10 tripunctato, striola scutellari mediocriter elongata. Long. 
12 mi Him. 
One example, apparently a female. The form of the tarsi, and especially the dilated and entire 
fourth joint, resembles still more closely that of the genus Calophcena ; and in spite of the latter belonging 
to the Truncatipennes division of the Carabidse, there may be a real affinity between the two genera. 
Family Cetoniida£. 
Prigestia viridiaurata. 
$ . Quoad formam P. vollenhoveni (Mohn.) simillima, differt colore supra et subtus viridi-aurato, 
tibiis tarsisque igneo-cupreis : sat nitida, supra glabra, capite grossissime crebre punctato, vertice 
profunde concavo, fronte carina lata obtusa antice declive et postice verticaliter truncata : 
thorace punctis umbilicatis annuliformibus medio distantibus, lateribus densiset subconfluentibus, 
linea dorsali areaque basali impunctatis : scutello subtilissime striguloso-punctulato : elytris 
planatis, paullo subtilius quam thorace annulato-punctatis, lateribus post medium apiceque dense 
strigulosis : 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. 
Mycteristes (Theodosia) telifer. 
Elongato-oblongus, aurescenti-viridis, elytris planatis flavescentibus. 
d . Caput et thorax passim densissime confluenter punctulata subopaca, hoc dorso subnitens punctulis 
subdiscretis ; scutello et elytris, pygidio, corpore subtus et pedibus subtilissime dense punctu- 
latis, sericeo-nitentibus : capite cornu sat brevi curvato, apice profunde bilido parum dilatato, 
frontis margine supra antennarum basin angulatim producto ; tborace dorso oblique valde elevato 
et in cornu porrectum elongatum robustum apice emarginatum (sub-bifidum) producto ; cornu 
dimidio apicali fronteque igneo-cupreis : pedibus anticis, praecipue tarsis, t r alde elongatis, tibiis 
extus acute et breviter bidentatis (apicali incluso), tarsis glabris. 
? . Caput densissime ruguloso-punctatum, clypeo sparsim grosse punctato, margine ante oculum 
indentato deinde antice flexuoso, clypeo angustato apice bidentato : tborace disco sparsim grosse 
umbilicato-punctato inter puncta subtilissime punctulato, lateribus 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 specific and not generic 
characters, just as they do in such genera as Onthophagus, Plianceus, and Copris. Of the numerous 
genera proposed, the present species approaches nearest to Theodosia , Thoms.

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 bead of the male the species
