fortiter punctato, metasterno minus fortiter; tibiis haud latis, 
antennis parum gracilibus, clava sat laxe articulata.

Laos: between Luang Prabang and Vientiane. 
A single specimen. . 
Although a little smaller, this has the same rather 
narrow form as 7. alternata, to which it is closely related, 
but the lower surface, including the legs, is entirely pale 
in colour, and the elytra are entirely black. The antennae 
are rather shorter than in that species, and the club is a 
little more compact and abrupt. The head and pronotum 
are a trifle less strongly punctured than in 7. alternata, 
and the interstitial punctures of the elytra are less evident. 
The clypeus is narrow and not emarginate in front. 
48. Tritoma ornata, sp. n. 
Laete fulva, capitis vitta mediana, prothoracis macula antica 
geminata vel bilobata, elytrisque nigris, his fascia antemediana 
multidentata transversa maculaque utrinque apicali triangulari 
fulvis ornatis, clava antennali (apice excepto) nigra; ovalis, con- 
vexissima, nitida, corpore supra ubique sat crebre punctato, clypeo 
parum brevi, fortiter emarginato, oculis modice prominentibus, 
pronoti marginibus lateralibus vix arcuatis, angulis omnibus fere 
rectis, basi anguste lobato; elytris fortiter punctato-striatis ; 
corpore subtus subtiliter, lateribus fortius, punctatis; antennarum 
articulo tertio quam quarto plus duplo longiori, clava ovali, modice 
compacta, articulo 9 lato, 11 minuto, 
Long. 4—5 mm.; lat. max. 2-5—3 mm.

This is intermediate between the rather depressed pre- 
ceding insects and the short and convex species repre- 
sented by 7. bipustulata F. It is more elongate than the 
last, more closely punctured, with more strongly marked 
elytral striae, and has longer antennae and tibiae, the 
antennal club being of the same general form but less 
compact. The last joint of the labial palpus is only a 
little wider than it is long. The coloration 1s like that of 
no other described species. The legs and lower surface 
are yellow, the head is yellow with a longitudinal median 
black line, the pronotum is yellow with two oval black 
spots more or less united occupying the middle of the 
front margin and extending backwards beyond the middle
