distant at their base, somewhat approximate in pairs on the 
hinder and outer portions of the disk, and are each impressed 
by a single row of distinct punctures ; deeply impressed im front, 
they become shallower and their puncturmg less distinct below 
the middle, and towards the apex of the elytron are quite obso- 
lete; the 9th and 10th rows are placed at a greater distance 
from the adjoining striz than any of the other pairs ; within the 
outer border is a deep impunctate sulcation, which extends the 
whole length of the margin. Hinder thighs not extending be- 
yond the elytra, their under surface furnished near the apex 
with a short ridge, either extremity of which is armed with a 
short tooth; hinder tibice with the basal half curved, the apical 
half nearly straight, the apex not mucronate; on their inner 
surface at the base is an obtuse tubercle. 
Fam. Megalopide. 
Temnaspis Mouhoti. 
T. elongata, parallela, fulva, nitida, pube suberecta vestita ; antennis, 
mandibularum apice, plaga transversa inter oculos, plaga verticali, 
thoracis maculis duabus disco transversim positis, elytrorum ma- 
culis sex, tibiarum apice tarsisque nigris. 
Var. A. Elytrorum maculis nigris obsoletis.

Head punctured, a flattened triangular space on the forehead, 
impressed on the centre of its basal margin with a deep fovea; 
epistome smooth, impunctate, impressed with a deep longitudinal 
groove; antenne as long as the head and thorax, black; the 
black patch on the face is transverse, and often extends quite 
across between the eyes; the latter prominent, their inner mar- 
gins narrowly and obliquely notched. Thorax rather broader 
than long, sides obtusely angled at their middle, deeply con- 
stricted just behind their apex; above subcylindrical, trans- 
versely grooved near the base and again in front, the anterior 
suleation running into the lateral constriction ; surface shining, 
subremotely punctured. Scutellum triangular, its apex notched. 
Elytra parallel, dehiscent at their apex, subelongate, upper sur- 
face rather more closely punctured than the thorax, longitudi- 
nally depressed along the suture, impressed at the base within 
the shoulders; basilar space obsoletely raised; on each elytron 
are three large black spots—one, oblong, at the base, extending 
over the humeral callus, a second, transverse, placed just before 
the middle, arising just within the lateral border and extending 
across nearly to the suture, and a third, subapical, triangular, 
its anterior border notched. Hinder thighs in the ¢ strongly 
incrassate, armed beneath near the apex with a stout tooth; in
