NALATA. 191 
Two of the species originally referred to it were subsequently transferred by Stal 
to his genus Microlestria. The Nalate differ inter se in the size and arrangement 
of the tubercles on the anterior lobe of the pronotum, as well as in the relative length 
of the basal joint of the antenne and the form of the scutellar process. The colour is 
more or less variable. The head has three prominent, conical, setiferous tubercles on 
each side beneath. The femora are asperate and setose; the anterior pair are strongly 
incrassate and armed beneath with two rows of short spines, amongst which are a few 
longer and stouter ones. The anterior tibiz are armed with a row of short fine spines, 
sometimes (XV. nigrescens) with stouter and longer spines intermixed. ‘The anterior 
trochanters are armed with a stout spine. 
Anterior lobe of the pronotum with two larger prominences or tubercles, 
separated by an oblique groove, on each side of the median sulcus; 
the head with moderately prominent tubercles above. 
Antenne with the basal joint infuscate: species larger and of dark 
coloration. | 
Pronotal tubercles very prominent; scutellar process cristate . . guadrituberculata, n. sp. 
Pronotal tubercles not prominent; scutellar process not cristate. . nigrescens, n. sp. 
Antenne with the basal joint pale and relatively very short: species 
smaller and paler, with the membrane and corium more or less 
variegate . . . 7 soe ee

Anterior lobe of the pronotum with small scattered conical tubercles, 
those on the disc more or less arranged in two series on each side of 
the median sulcus, these series each continued as an oblique ridge 
on to the posterior lobe.

1. Nalata quadrituberculata, n. sp. (Tab. XI. figg. 23, 23a, 3.) 
Moderately elongate, rather broad, fuscous or nigro-fuscous, the under surface slightly mottled with ochreous, 
the connexivum with the apex of each segment ochreous; the elytra with a large common patch adjoining 
the apex of the scutellum, and a spot at the base of each of the two inner cells of the membrane, nigro- 
fuscous ; the femora, tibic, and rostrum more or less distinctly annulated with ochreous; the antenne, 
rostrum, legs, and body set with long, scattered, bristly hairs, the body and corium also sparsely clothed 
with short, stout, curled, decumbent, ochreous or rusty-brown hairs. Head with moderately prominent 
tubercles above, the ocelli prominent, the eyes large and prominent; antenne elongate, joint 2 nearly 
twice as long as 1, 3 longer than 2, 4 about half the length of 3. Pronotum with the anterior lobe 
gibbous and strongly bituberculate on each side of the median groove, the scattered tubercles small and
