nearly as long as the cerci. Underside blackish; legs dark 
red. Tegmina hardly as long as the abdomen, almost equally 
broad throughout ; hind margin obtusely rounded, dark rufo- 
castaneous, covered part of the right tegmen yellowish, more 
or less conspicuously bordered with rich purple. Wings with 
the costal area brown; nervures yellow in the basal half of 
the costal area and also the longitudinal nervures towards the 
base ; the rest of the wing hyaline. 
Hab. New South Wales. 
Allied to M. convera, Walk. (Cat. Blatt. B. M., Suppl. 
p- 152, 1869), from Moreton Bay, but in I. convexa the head 
is black. Paraphoraspis (?) castanea, Tepp. Trans. Roy. Soc. 
S. Australia, xviii. p. 173 (1894), appears to be another 
allied species.

Hab. Australia. 
De Haan’s description of his Blatta ( Periplaneta) concinna 
(Orth. p. 50), from Java, appears to apply to P. Borret, 
Sauss., which is in the British Museum, from Java and Hong 
Kong. Itisa species of Methana allied to M. pallipalpis, 
Serv. Brunner’s species thus falls under a different genus, 
and when a second species is described as the same as another, 
and they prove to be distinct, it seems to me that we have no 
alternative but to change the name of the later one, even 
though it may fall under another genus in which the name 
has not previously been used. 
Genus PELMATOSILPHA, Dohrn. 
This is a small genus, but its contents do not seem to be 
very homogeneous; still I cannot venture to subdivide it, as 
I am unacquainted with the types, P. alaris, Sauss., and 
P. prestans, Dohrn. P. marginalis, Brunn., and the two 
other West-Indian species described below form a very 
natural group with short tegmina, while the Australian 
species will probably form another genus. 
Pelmatosilpha purpurascens, sp. n. 
Long. corp. 25-30 millim. 
Head pale yellow above, brown below, with the sides and 
lower part sometimes varied with tawny. Antenne ferru-
