AND SPECIES OE G-ALERUCINJE. 
175 
Hab. Assam: a single specimen. 
Antennae filiform ; eyes black. Thorax nearly twice as broad 
as long ; sides nearly straight, diverging from the base to 
beyond the middle, thence obliquely converging towards the 
apex; disk smooth, nearly impunctate, impressed just behind 
the middle with a transverse groove. Elytra rather strongly 
punctured. 
10. Pseudocophora perplexa. Ovata, postice paullo ampliata, 
convexa, pieeo-fulva, nitida, metapectore, abdomine pedibusque 
posticis quatuor nigris, antennis, tibiis tarsisque anticis pallide flavis ; 
thorace sat profunde ti’ansversim sulcato ; elytris tenuiter punctatis. 
Long. 31 lin. 
Fern. Abdominis pygidio apice leviter angulato-emarginato ; segmento 
anali apice obtuso, obsolete sinuato. 
Sab. Philippine Islands. 
Antennae yellowish white. Thorax nearly twice as broad as 
long ; sides slightly diverging and sinuate from the base to 
beyond the middle, thence converging towards the apex, the 
hinder angle acute, the anterior slightly produced, obtuse ; upper 
surface transversely convex, deeply sulcate transversely im- 
mediately behind the middle, the sulcation nearly as deeply 
impressed in its median portion as on its sides ; disk smooth, 
impressed with a few distant punctures on the sides. Elytra 
oblong, slightly dilated posteriorly, convex, finely but distinctly 
punctured. 
The present insect closely resembles the same sex of P. ambusta, 
var. A; but the entirely different form of the pygidium in the 
two species at once separates them. 
Genus Aulacophora, Chevr. 
The first six species here described have simple antennae in 
both sexes ; in the last eight the antennae in the males have the 
third to the sixth joints compressed, and more or less thickened 
and dilated ; the females of this section appear to be much rarer in 
collections than the other sex, and only in a few cases are known 
to me. The following Table gives the differential characters ot 
the males of this latter group : —
