36 Mr. J. Wood-Mason on Mantis metallica. 
parts of the thoracic sterna, and a short streak on the extre- 
mity of the dorsal crest of the four posterior femora pale 
turquoise-blue; head between juxtocular bosses from vertex- 
line to ocelli, and the disk of both lobes of the pronotum yellow, 
of the shade of autumn leaves; tegmina yellow-green, clouded 
with reddish fuscous, and narrowly edged in front with jet- 
black, their anal area red at the very base, beyond which the 
veins are red and the meshes smoky ; wings with base and an- 
terior area rather opaque, red, passing into yellow at extremity, 
as to the rest black-smoky with purple reflections ; abdomen 
above dark steel-blue, tipped with yellow. 
Head thicker than in A. pulchra; forehead marked by five 
longitudinal grooves ; facial shield a little longer, its obtuse- 
angled basal margin projecting very slightly in the middle 
line, its disk furnished on each side with a transversely elon- 
gated tubercle, representing the ridges present in A. pulchra ; 
clypeus transversely elevated into a prominent angulated 
ridge, from the middle of which a strong longitudinal ridge 
runs. forward to the anterior margin of the part; labrum 
convex. ; 
Pronotum robust, only about twice as long as broad, tra- 
versed along the middle from about the commencement of the 
posterior fourth of the anterior up to the pair of smooth eleva- 
tions near the hinder end of the posterior lobe by a coarse 
ridge; strongly constricted posteriorly; the portion of it 
lying in front of the constriction having an oval outline, which 
is slightly broken on each side antero-laterally by a faint 
flattening or oblique truncation of the edge; the prominent 
heart-shaped disk of its anterior lobe having two conspicuous 
oval wrinkled elevations, placed obliquely on each side of the 
posterior end; its posterior lobe having the muscular impres- 
sions at the anterior end large and deep, and the part of the 
disk between these impressions and the constriction somewhat 
inflated on each side, so that the groove in which, in the 
allied species, the ridge is throughout lodged is, in this part 
of its length, effaced ; its finely-denticulate lateral margins a 
little lamellar. 
Organs of flight extending by about one sixth of their 
length beyond the apex of the abdomen, of the same structure 
and texture as in A. pulchra; the discoidal vein of the wings 
3-branched, with one of the branches on one side bifurcate. 
Legs longer and slenderer. 
Abdomen oval, about 1} times as long as broad. 
Total length of body 28 millim.; length of pronotum 8, 
breadth of pronotum at dilatation 4°5; length of abdomen 12,
