840 MR. NELSON ANNANDALE ON THE [ Dee. 45 
expansions of the femur of the posterior limbs had that semi- 
opalescent, semi-crystalline appearance that is caused in flower- 
petals by a purely struetural arrangement of liquid globules or of 
empty cells. On the grasping-linbs and on the extremities of the 
other pairs the absence of this pectliar sheen was compensated for 
by the translucency of the integument and the tissues—a trans- 
lucency more proper to Celenterates than to an air-breathing 
insect. The petals of Melustoma polyanthum, the flower with which 
the Mantis was found associated, are of mauve-pink on the upper 
surface, slightly darker in tone than that of the limbs of the imsect. 
Their lower surface, and consequently the visible surface of the 
older flower-buds, is considerably darker than the upper, more like 
that of the Mantis’s abdomen. The leaves are of the same shade 
of green as the bar across its thorax. The flower was in bloom in 
Pupa of Hymenopus bicornis on infloreseence of Melastoma polyanthum. 
(Photographed from life.) 
The Mantis is seated in an upright position, with the abdomen flexed back- 
wards. ‘The photograph represents it «s it is seen on a level with the eye, and 
shows the horn-like eyes of the insect (at the apex of figure), the V-shaped bar on 
the thorax, the predatory limbs folded in fromt of the body, the petal-like 
expansions of the femora of the 2nd and 3rd pairs of legs arranged on the 
flowers, and the ventral surface and dark tip of the abdomen. The tarsus of 
the left leg of the 3rd pair is seen stretching out from beneath the expansion 
of the femur to a seed-yessel of the plant.
