22 HEMIPTERA-HETEROPTERA. 
MACROTINGIS, n. gen. 
Rostrum extending to the meso-metasternal suture. Rostral groove slightly narrowing to the base of the 
mesosternum, and then widened out into an oval space on the metasternum, uninterrupted, closed in 
front, the sternal lamine moderately prominent. Antenne distant at the base, exceedingly elongate, 
extending to far beyond the apex of the elytra, slender, joint 1 very long, about twice as long as 4, 
equalling the femora in length, 2 very short, 3 nearly two and a half times the length of 1, 4 lanceolate, 
pilose, and stouter than the others. Head with a single long erect frontal spine. Pronotum with 
moderately wide membranous margins, a rather small oval hood, and a median and two lateral carine, 
the latter short, the posterior portion elongate-triangular. Elytra narrow, elongate, extending to far 
beyond the abdomen, hyaline; costal area bi- or uniseriate; discoidal area not nearly reaching the 
middle, the subcostal area very long and narrow; median nervure feebly sinuate. Legs very elongate 
and slender. Orifice not visible. 
Two closely allied species belong to this genus. The extremely elongate antenne 
with relatively very long basal joint (this being about twice as long as the apical one, 
and equalling the femora in length), long legs, prominent frontal spine, &c., distinguish 
it from Leptostyla, to which it is perhaps most nearly allied. 
1. Macrotingis biseriata, n. sp. (Tab. II. figg. 8; 8a, profile; 8 4, part of 
the body beneath.) 
Elongate, narrow ; ferruginous or testaceous, the head rufous, the disc of the pronotum in front and the body 
beneath black, the last two segments of the abdomen excepted, the elytra with a spot at the end of the 
discoidal area, and a faint oblique fascia towards the apex, sometimes extending forwards along the 
sutural area, fuscous ; the antenne testaceous, with the apical joint black; the legs testaceous, with the 
tarsi black ; the pronotal margins and hood, and the costal margin and median nervure of the elytra to 
about the middle, set with very fine scattered hairs. Pronotum with the disc closely punctured and 
shining; the carine parallel, the outer ones abbreviated in front and not extending on to the convex 
portion of the disc; the hood small, projecting over the base of the head; the membranous margins 
rounded and recurved, converging a little in front and rounded behind, with two rows of areole, the 
areolz of the outer row large and transversely tetragonal, those of the inner row small. Elytra very 
little wider than the pronotum, narrowing a little at the base and rounded at the apex; discoidal and 
subcostal areas, and the outer half of the sutural area to beyond the middle, closely reticulated, the rest 
of the reticulation wide and subequal; costal area with two rows of mostly tetragonal cells, diminishing 
to one at the apex; discoidal area limited within and without by a sharply raised nervure. 
extending to a little beyond the apex of the abdomen. 
Length 5, breadth 13 millim, 
Hab. Panama, Bugaba, Volcan de Chiriqui 3000 feet (Champion). 
Found in abundance on the slopes of the Volcan de Chiriqui, in the vicinity of the 
coffee-plantations. The hairs on the costa of the elytra are usually missing, but the 
minute denticules from which they arise are always to be seen. 
Wings long, 
2. Macrotingis uniseriata, n. sp. (Tab. II. figg. 9*; 9 a, profile.) 
Very like M. biseriata, and similarly coloured, but a little smaller and narrower; the pronotal margins less 
dilated, with the outer row of areole much smaller; the costal area of the elytra narrower, with a single 
series of tetragonal areole throughout. 
Length 43, breadth 17 millim. 
Hab. Guatemaua, Capetillo (Champion).
