collected by the late M. Mouhot, Sc. 307 
third scarcely longer than the second, the second and third toge- 
ther about equal in length to the first, the fourth and fifth longer, 
the remainder about equal in length, dilated. Thorax widest 
behind, very short. Scutellum very large, cordiform, slightly 
carinated on each side. Elytra widest at the shoulders, sides 
somewhat sinuate, apex sexspinose. Prosternum flat. ‘Tarsi 
somewhat dilated. 
Differs from Dicercomorpha, H. Deyr., by its large cordiform 
scutellum, its general facies, and especially by the epistome being 
carinated and produced on either side, so as to form the inferior 
margins of the antennary cavities, 
Cardiaspis Mouhotii, n. sp. (Pl. XXI. fig. 9.) 
C. viridis, punctata; thoracis disco elevato; elytrorum apice 
sexspinoso ac ciliato. 
Bright green, punctured. Head deeply punctured on the 
vertex, with a deep ovate fovea between the eyes in front, the 
margins of which are elevated, irregular, quite smooth and bril- 
liant. Thorax much enlarged behind, twice as broad at the base 
as long; the anterior margin only half as wide as the base, 
almost straight, smooth, lined with fine cilia of white hairs; sides 
gradually rounded, elevated and smooth, base largely lobed, disk 
deeply punctured and somewhat rugose, slightly elevated pos- 
teriorly, the posterior angles of the elevation forming two bright 
spaces on the base, each placed midway between the centre and 
the lateral margin ; sides rugose, foveated irregularly along the 
margin, and a slight fovea on each side of the discal elevation. 
Scutellum very large, transversely cordate ; with a depression in 
the centre and a deeply cut straight line on each side of it. Ely- 
tra striate, wider than the thorax ; humeral angles much enlarged, 
sides somewhat converging behind the shoulders, then swelling 
out as far as the centre, whence they gradually converge to the 
apex, which is truncate and armed with six strong spines, the two 
external ones broad and pointing outwards; the apex is also 
finely ciliated ; striae somewhat punctuated, the interstices more 
deeply, punctures increasing in size and depth as they approach 
the sides. Beneath punctured, covered with sparing white hairs; 
apical segment more densely clothed, carinated along the centre, 
and bidentate at the apex. Legs punctured, slightly hairy; tarsi 
bluish-green. 
Length 123 lines; breadth 53. 
Laas.
