Mr. B. Shelford’s Studies of the Blattida. 2t0 
On referring to the Banksian cabinet I found two specimens 
belonging to distinct species under the name Llatta brasi- 
licnsis; one measured in total length 18 mm., and had the 
abdomen fuscous beneath, the other measured 25:1 mm., 
and had the abdomen beneath rufous with pale disc. The 
former specimen corresponds the more closely to the diag- 
nosis of Fabricius and may be selected as the type of the 
species; the following is a description of it :— 
g. Dulltestaceous. Head with afew small brown macule on the 
front and face, palpi pallid ; (antennes broken). Pronctum broadly 
transverse not covering the vertex, lateral margins broadly hyaline, 
dise testaceous, unspotted. Tegmina testaceous hyaline, un- 
spotted ; mediastinal vein unbranched, radial vein with eight 
costal branches, the two last bifurcate, apex of radial vein ramose 
and not reaching end of tegmina, anterior ulnar vein bifurcate, 
the branches becoming ramose, posterior ulnar vein simple, anal 
sulcus strongly marked, four axillary veins. Wings hyaline, veins 
testaceous. Abdomen fuscous above and beneath becoming rather 
paler towards the extremity ; supra-anal lamina produced subquad- 
rately, testaceous, posterior border slightly emarginate ; sub-genital 
lamina semi-orbicular, ample, with large acuminate styles (cerci 
mutilated, fuscous). Legs testaceous, cox with fuscous line on 
outer border ; front femora with ten spines on the anterior margin 
beneath, extending from the middle to the apex, the middle ones 
longest, four spines on posterior margin, mid-femora with six spines 
on anterior margin, three on posterior margin, hind femora with six 
spines on anterior margin, four on posterior margin, formula of 
apical spines j, +, 4, of genicular spines 0, 1, 1. 
Total length, 18 mm. ; length of body, 12-2 mm.; length of 
tegmina, 15 mm.; breadth of pronotum, 6°5 mim. 
The other specimen is slightly darker in colour. ¢. Eyes whitish- 
grey, face testaceous, a rufo-fuscous stripe on the frons extending 
down to the base of the clypeus, thinning out to a line on the vertex. 
Pronotum more trapezoidal, lateral margins hyaline. Tegmina with 
two-branched mediastinal vein, radial vein giving off eleven costals, 
its end ramose, seven axillary veins. Abdomen rufous beneath with 
the dise paler; supra-anal lamina triangularly produced ;_ sub- 
genital lamina narrow, produced, asymmetrical with one acuminate 
style. Front femora with two spines on anterior margin beneath in 
the middle, four on the posterior margin (hind femora lost), formula 
of apical spines, $, +? 
Total length, 25:1 mm.; length of body, 17 mm. ; length of 
tegmina 21 mm. ; (pronotum crushed).
