NALATA. 193 
Hab. Panama, Bugaba (Champion). 
Three specimens. Very like W. setulosa, but broader and more robust, with the 
corium and membrane mottled with paler colour, the basal joint of the antenne shorter, 
and the scutellar process stouter and less compressed; the anterior lobe of the 
pronotum is more gibbous, the two callosities being each divided into two prominences, 
and the posterior lobe is without definite ridges. NV. irrorata is also closely allied to 
the Brazilian WV. aspera, Stal (the type of which is before me) ; but in the latter the 
membrane is uniformly nigro-fuscous, with the base only pale, the anterior lobe of 
the pronotum has two converging rows of conspicuous whitish tubercles in front, and 
the head is not so abruptly constricted behind. 
4. Nalata spinicollis, n. sp. (Tab. XI. figg. 27, 27a, 2.) 
Rather broad, ochreous, the sides of the head behind the eyes, the posterior lobe of the pronotum, the middle 
of the scutellum, and the elytra fuscous, the elytra with a spot at the inner apical angle of the corium 
and one at the base of each of the two cells of the membrane black ; the connexivum broadly banded 
with fuscous; the apical two joints of the antenne blackish; the underside of the body mottled with 
fuscous ; the femora annulated with fuscous at the base; the tibie with the base, apex, and an annulus 
before the middle, fuscous; the antenns, rostrum, legs, and body set with long, scattered, erect or 
semierect, bristly bairs or sete, the body above and beneath, and the corium, also very sparsely clothed 
with short, stout, decumbent, curled, ochreous hairs. Head armed above with numerous stout conical 
setiferous tubercles, the two between the ocelli, the two on cach side near the eyes, and the one in the 
centre in front being very conspicuous, the latter bearing two sete, the ocelli small and widely separated ; 
antenne reaching to a little beyond the hind angles of the pronotum, joints 1 and 2 rather stout, 2 one- 
half longer than 1, 3 and 4 very slender, 3 nearly one-half longer than 4. Pronotum dilated behind ; 
the anterior lobe gibbous on the disc on each side of the broad median sulcus, and armed with numerous 
very prominent, stout, conical, setiferous tubercles—about nine on each side, three of which are marginal ; 
the posterior lobe with indications of two anteriorly converging ridges on the disc, these being limited in 
front and behind by a setiferous tubercle; the hind angles rather sharp. Scutellum with the margins 
raised and tuberculate, the apical process rather stout and also tuberculate above. Femora strongly asperate. 
Length 7-74, breadth 23-24 millim. (2.) 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 
Three specimens. This species is allied to WV. setulosa, Stal, but differs from it, and 
from all others of the genus, in the very prominent, stout, conical tubercles on the head 
and anterior lobe of the pronotum, these being much more conspicuous than in 
N. aspera, Stal. 
5. Nalata rudis. (Tab. XII. figg. 1, La, ¢.) 
Nalata rudis, Stal, Stett. ent. Zeit. 1862, p. 457*; Enum. Hemipt. 11. p. 120’. 
Hab. Mexico? (coll. Signoret}, in Mus. Vind. Ces.). 
The type of this insect is before me. It is very like NW. setulosa, but the pronotum 
is less widened behind, and the conical tubercles on the anterior lobe are more numerous 
and form two well-defined series on each side of the disc and a row (of about eight) 
along the lateral margins, each of the series on the disc being continued on to the
