spine, as it is very nearly in tlie two other species. The inequalities of the surface are the same in all— 
the common basal elevation being quadrate and plane above, tuberculated on its margin, and the disk 
having a rounded tubercle before and an oblique elongated callus behind the middle. 
Mr. Whitehead obtained also examples of the following species of Cicindelidae :— Cicindela crespignyi 
(Bates, since redescribed as C. borneeana, Dokhtouroff) in a distinct colour variety, the broad orange- 
coloured belt and stripe of the type-form (from near Labuan) being replaced by white ; the rare Hepta- 
donta tricond.yloides (Gestro) ; Therates punctipennis (Bates), many examples, all alike in the uniform 
pale colour of the elytra, but still little more than a colour variety of T. schaumi (Chaud.) ; and Tncondyla 
beccarii (Gestro). 
Family Cakabid.e. 
OODES (SlMOUS) BOKNEENSIS. 
0 . ceneo (Laferte) proxime affinis, sed differt corpore angustiore supra inulto minus polito, prseterea 
colore violaceo vel viridi-cyaneo etc. Auguste elongato-oblongus ; palpis, antennis tarsisque 
(vel pedibus totis) picescenti-rufis : thorace post medium latiore, antice valde angustato, supra 
Isevi, puncto setifero ad angulum posticum : elytris tenuiter sed acute orenulato-striatis, margine 
ante apicem sat fortiter sinuato, interstitiis planis, 3 io longe post medium unipunctato : subtus 
niger, nitidus. Long. 15-1(3 millim. $ $ . 
Two examples. Found also in South-eastern Borneo. The genus Simons was separated from Oodes 
by Chaudoir chiefly on account of the extremely short six-punctate labrum and the setiferous puncture 
close to the hind angles of the thorax. It forms a perfectly natural group, of which five species are now 
known, peculiar to Indo-China and the neighbouring islands. 
CoLPODES EEYI. 
Species magna elongataque C. paralleio (Chaud.) affinis. Valde elongatus relative angustus, elytris 
lateribus parum rotundatis ; nigro-seneus, elytris Ice tins cuprascenti-aeneis : capite pone oculos 
gradatim recte angustato, collo supra transversim depresso : thorace subquadrato, capite paullo 
angustiore, lateribus paullo ante medium leviter rotundatis versus basin sinuatis, angulis posticis 
obtusis, margine anguste explanato-reflexo : elytris simpliciter acute striatis, interstitiis usque 
ad apicem planis, 3 10 punctis magnis tribus, versus apicem oblique sinuatis, juxta suturam 
breviter sinuato-truncatis et utrinque bidentatis : tarsis robustis, subtus dense pilosis, 4 posteri- 
oribus supra valde bisulcatis medioque carinatis, articulo 4 t0 extus lobato. Palpi, antennae et 
pedes rufescenti-picei. Long. 17 millim. $ . 
One (female) example. The species belongs to the numerous group of the genus distributed through 
South-eastern Asia and its islands, in which the metathoracic epimera are long and narrow, the fourth 
joint of the hinder tarsi strongly unilobular, and the sutural apex of the elytra briefly truncated and more 
or less spined or toothed. 
Euplynes auko-cinctus. 
Breviter oblongus, subdepressus, piceo-niger, politus ; elytris splendide viridi-feneis, lateribus late 
auratis ; antennis (scapo obscuriore), mandibulis et palpis apice tarsisque rufescentibus : capite 
brevi mox pone oculos magnos subito angustato, supra planato laevi, sulcis frontalibus dexuosis 
postice versus oculos curvatis : thorace lato et brevi, angulis anticis rotundatis, posticis fere rectis, 
lateribus medio rotundatis postice usque ad angulum leviter sinuatis, margine basali utrinque 
ad angulum ascendenti, foveis basalibus latis sat profundis punctulatis : elytris humeris valde 
rotundatis, apice sinuatis, versus suturam conjunctim obtuse rotundatis, acute punctulato-striatis, 
interstitiis planis, striis 3 a -7 m versus basin valde curvatis, ibique interstitio 5° fovea magna 
oblonga. Tarsi subtus dense pilosi, articulo 4° (sicut in Enplyni) longe bilobato. Long. 8 millim. 
This interesting species has also been met with in Sumatra by Dr. Beccari. 
Dixopelma, nov. gen. 
Genus anomalum, facie Platyni vel Colpodis sed tarsis sicut in Hexagonia ; subfam. Ctenodactybinai 
referendum. Caput subovatum, post oculos rectilineatim oblique angustatum, foveis frontalibus 
maximis fundo inaequalibus, collo sat angusto supra transverse depresso ; mandibula elongata sat 
recta robusta; maxillae (?) ; mentum medio late obtuse dentatum, lobis latis extus et apice 
rotundatis; ligula cornea, antice lata integra bisetosa, paraglossis tenuibus liberis; palpi (desunt); 
labrum recte truncatum. Antennae mediocres, articulis 3°-10 m subaequalibus, 1°-3 U1 et 4 U basi
