Mr. R. Shelford’s Studies of the Blattide. Zak 
the lists of Blattidse described by earlier authors ; neither 
Brunner nor Kirby mention it. The type specimen from 
the Marchal collection is in the Hope Museum, Oxford, 
and from an examination of it Iam able to place it with- 
out a doubt in the genus Homalosilpha. An identical 
example from Mt. Penrissen, Sarawak [No. 28] gives the 
habitat of this species that has for so long been unrecog- 
nized. It may be mentioned that another of Serville’s 
types of Blattide, viz. Blatta alcarazzas, is also in the 
Oxford Museum. 
Genus MIROBLATTA, Nov. 
Head covered by the pronotum, eyes closer together than the 
antennal sockets ; antennee very long, third joint twice as long as 
second. Pronotum longer than broad, anterior border arcuate, 
posterior border truncate, exposing the scutellum ; markedly cucul- 
late and narrowed anteriorly, anterior and lateral margins reflected, 
dise with symmetrically disposed elevated ridges. Tegmina broad, 
oval, barely reaching extremity of abdomen, overlapping consider- 
ably, apex obtusely rounded ; corneous, densely reticulated, vena- 
tion obscured, no anal vein or anal field, radial vein strongly 
elevated at base, mediastinal field on under surface elevated, keeled, 
space between mediastinal and radial veins broad, inflexed, forming 
with mediastinal field an epipleuron, the outer margin of which is 
the anterior margin of the tegmen, the inner margin formed by the 
mediastinal vein. Wings broadly ovate, of same length as tegmina, 
coriaceous, anterior part nearly twice as broad as posterior part, the 
outer margin deeply indented at the point of division between the 
two parts, the wing appearing bilobate ; mediastinal and radial 
veins fused, their base elevated forming a prominent ridge, six 
ramose branches given off to apex and outer margin, ulnar vein 
reduced with three ramose branches only, numerous transverse 
venules between all the veins; posterior part of wing not folding 
in fan-like manner but merely doubling under anterior part. Supra- 
anal lamina of male broadly transverse, slightly emarginate. Sub- 
genital lamina of male subquadrate, styles minute. Cerci long, very 
sharply pointed. Legs long, slender ; femora unarmed beneath ; 
spines on posterior tibiee in two rows. Posterior tarsi with meta- 
tarsus longer than remaining joints, no spines beneath, pulvilli large, 
the second occupying whole length of joint. Female not known, 
probably apterous. 
The affinities of this highly remarkable genus appear to
