new Species of Blattide. AL 
Subfam. Oxr#4torv 2. 
Genus OxyHaAtoa, Br. 
Oxyhaloa variabilis, sp. n. 
¢. Rufo-castaneous. Vertex of head rufo-castaneous, a 
clear testaceous band between the antenne, gene testaceous ; 
frons, clypeus, labrum, palpi, and antennz shining black. 
Pronotum with two oblique impressions anteriorly, with a 
few minute punctures from which spring short slender hairs. 
Tegmina with the veins fuscous, sparsely pubescent, very 
variable in length, in some examples reaching tip of abdomen, 
in others lanceolate and extending no further than the third 
tergite ; thirteen costals ; discoidal field reticulate. Wings 
as variable in length as the tegmina, flavid at base, the rest 
infuscated ; veins fuscous, ulnar vein with eight to nine rami, 
the basal ones transverse. Abdomen broad, black above, 
the margins of the segments narrowly rufous, beneath rufo- 
castaneous ; supra-anal lamina short with rounded posterior 
angles, not emarginate ; subgenital plate projecting beyond 
the supra-anal lamina, fuscous, ample, its margin sinuated ; 
cerci short, fuscous, tipped with rufous. Legs black, apices 
of coxee and femora rufous, tibial spines rufous. 
Total length from 16 mm. to 13°5 mm.; length of body 
from 16 mm. to 12°5 mm.; length of tegmina from 11 mm. 
to8 mm.; breadth of pronotum from 6°2 mm. to 5 mm. ; 
length of pronotum from 4°5 to 4 mm. 
Interior of Djibouti (Hermann); one example (Paris 
Museum). 
This is the smallest species of the genus, and is remarkable 
on account of the variation in size of the wings and tegmina ; 
apparently this variation bears no relation to the variation 
in size of the individual, for one of the smallest specimens 
has long tegmina and one of the largest has these organs 
much reduced. 
Genus ParapLecta, nom. nov. 
(= Cirphis, Stal.) 
The name Cirphis, created by Stal in 1876 (ify. Vet.- 
Akad. Forh. xxxii. p. 74) for a cockroach (C. pailipes) from 
Damara Land, is preoccupied, having been applied by Walker 
in 1865 to a genus of Noctuid moths.
