118 J. Wood-Mason—On a new Genus of Phasmide, 
Colour—deep black-brown, almost black, blotched with yellow, sparingly 
so on the undersurface and legs, but more profusely on the pronotum and 
on the terga of the abdominal somites, on which parts the colour assumes 
an orange tinge and extends to the points of the spines; the antenne 
are ringed at the joints with the same colour; organs of flight, greenish 
yellow, with their bases and principal nervures black. 
g. Length of body 61 millims., of head 7, pronotum 5, mesonotum 
14, metanotum 7, abdomen 25 + 7 = 82, tegmina 2°5, wings 8, fore femur 
17, tibia 17:25, intermediate femur 13°5, tibia 15°5, posterior femur 17, 
tibia 21, antennz 53. 
Q. Length of body 86 millims., of head 10, pronotum 7, mesonotum 
18, metanotum 10, abdomen 31°5, + 12°5 = 44, tegmina 4°5, wings 105, 
fore femur 19, tibia 20, intermediate femur 16, tibia 18, posterior femur 
21, tibia 25, antennz imperfect. 
Hab.—3 ¢ and8 92 from Fianarantsoa ; and 1 ? from Antananarivo, 
Madagascar, differing from the rest only in he much more variegated. 
2. Parectatosoma echinus, n. sp. 
32. Slenderer, and less numerously and less strongly spined than 
the preceding. Head armed: ? with 10 spines besides spinules, the cepha- 
lic horns more foliaceous and more sharply spined, with only one pair of 
spines in front of them instead of two and that simple: ¢ with 8 only, 
one of the lateral pairs not being developed. Postantennary spines reduced 
to minute tubercles. Vestiges of wings and tegmina larger, those of the 
latter overlapping one another, and those of the former so as to conceal from 
view all but about one square millimetre of the unarmed metanotum. The 
tergum of the Ist abdominal somite with but one row of spines at its 
hinder end; that of the terminal somite ? divided at its posterior margin 
into four spinous processes. 
Colour—body brown like rotten leaves, with the legs, antennz, organs 
of flight (which have their principal nervures darker), and spines lighter. 
$. Length of body 64 millims., head 4°5, pronotum 45, mesonotum 
14, metanotum 6, abdomen 27°25 + 8:5 = 35°75, tegmina 3°75, wings 7°3, 
fore femur 17, tibia 17, intermediate femur 12°5, tibia 13°5, posterior 
femur 17°5, tibia 19°5, antennz 47. 
2. Length of body 80 millims., head 7, pronotum 6°5, mesonotum 
16:5, metanotum 8, abdomen 31 + 12 = 43, tegmina 6, wings 11, fore 
femur 16:6, tibia 17, intermediate femur 12°5, tibia 13'6, posterior femur 
18, tibia 21, antenne 43°5. 
The fore legs and all the tibie in the male of this species are nearly 
quite simple. 
Hab.—1 ¢ and 2 ? from Fianarantsoa.
