340 HEMIPTERA-HETEROPTERA. 
Three specimens. Very like S. sulcicollis, but. darker and a little more elongate, the 
elytra shining throughout and more sparsely pilose, the head smooth behind, the anterior 
lobe of the pronotum not so deeply sulcate down the middle, the antennz not so stout. 
8. Salda sulcicollis, n. sp. (Tab. XX. fig. 4.) 
Ovate, very shining, the clavus (except along the suture) opaque; the upper surface thickly clothed with 
long, erect, blackish hairs, between which a very short, fine, decumbent golden pubescence is visible ; 
black, the elytra with two distinct yellowish or whitish lateral spots, one before the apex of the corium 
and the other on the membrane, and indications of smaller scattered spots, the membrane fuscous, with 
pale spots; the antenne testaceous, with the third and fourth joints, and the apex of the second, more or 
less infuscate, the fourth sometimes pale at the tip; the rostrum, coxe, and legs testaceous, the tibia and 
tarsi annulated with fuscous. Head rugulose behind the ocelli, the latter narrowly separated ; antenne 
long and rather stout, about reaching the apex of the clavus, joint 2 one-half longer than 3, 3 and4 
subequal in length, all the joints shortly pubescent and also clothed with long, fine, projecting hairs. 
Pronotum very narrow in front, narrowly explanate at the sides, the latter rapidly and obliquely converging 
from the base forwards; anterior lobe deeply suleate down the middle, the two callosities thus formed 
being limited before and behind by a deep transverse groove, which is impressed with a row of punctures. 
Scutellum and elytra almost smooth, the membrane with four areole. Legs shortly pilose, the tibie with 
scattered sete. 
Length 33-43, breadth 12-23 millim. (¢ 9.) 
Hab. Mexico, Omilteme in Guerrero (H. H. Smith); GuateMaa, Coban, San Joaquin, 
and San Geronimo in Vera Paz, Guatemala city, Capetillo, Panajachel (Champzon) ; 
Panama, Volcan de Chiriqui 4000 feet (Champion). | 
Apparently the commonest species of the genus within our limits, and easily recog- 
nizable by the almost smooth, shining, hairy upper surface, the clavus only being opaque, 
and the comparatively stout, elongate antenne. SS. ductwosa, Stal, from California, the 
type of which is before me, has the pronotum much less narrowed in front, the antenne 
shorter and more slender, the corium entirely black, &c. S&S. andinus, Dist., from 
Kcuador, is less elongate, and has the clavus shining, the elytra differently marked, &c. 
4, Salda opacipennis, n. sp. (Tab. XX. fig. 5.) 
Broad ovate, short, very shining, the elytra entirely opaque; the upper surface thickly clothed with long, erect, 
blackish hairs, between which a very short, scattered, decumbent, golden pubescence is visible ; black, the 
elytra with an elongate testaceous patch at the middle of the corium externally, a transverse pallid mark 
towards the apex of the latter, and indications of some scattered whitish spots, the membrane fuscous, 
with pale spots; the antenne blackish, with the basal joint obscure testaceous ; the rostrum, coxe, and 
legs testaceous, the tibia and tarsi annulated with fuscous. Head smooth behind the ocelli, the latter 
narrowly separated ; antenne comparatively short, extending very little beyond the hind angles of the 
pronotum, slender, joint 2 one-half longer than 3, 3 and 4 equal in length. Pronotum almost smooth, 
very short and broad, broadly explanate at the sides, rapidly narrowing forwards, the margins a little 
rounded; anterior lobe deeply foveate in the middle and limited behind by a very deep transverse groove. 
Scutellum and elytra almost smooth, the membrane with four areole. Legs pilose, the tibia with 
scattered sete. 
Length 33, breadth 14 millim. (<¢.) 
Hab. Mexico, Omilteme in Guerrero 8000 feet (Hl. H. Smith).
