with a dark fuscous spot at inner angle; membrane pale brownish, the basal angle and apical third 
dark fuscous ; legs ochraceous, femora and tibie annulated with brownish. 
Long. 4 millim. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
This species not only differs from MZ. granulata by the above described colour- 
differences, but has the posterior margin of the pronotum much more prominently 
convex and the lateral pronotal angles more distinctly subnodulose ; the pronotum and 
scutellum are also less rugulose than in the preceding species. 
CARNUS, gen. nov. 
Body convex, glabrous, shining. Head moderately convex, smooth. Antenne with the basal joint not quite as 
long as the head; second joint about twice as long as the first, its apical half incrassated ; third and 
fourth slender, and together either almost equal to or more or less shorter than the second. Pronotum 
coarsely punctate, elongate, with a broad distinct anterior collar preceded by a transverse impression ; 
the anterior margin about one third the width of posterior margin, which is either convexly rounded or 
truncate. Scutellum somewhat tumid, shining, and glabrous. Corium somewhat convexly dilated. 
Rostrum reaching the intermediate coxe. Tibie indistinctly setose. 
a. Posterior margin of the pronotum convex. 
1, Carnus lunatus, n. sp. (Tab. XXVIII. fig. 6.) 
Ochraceous; posterior margin of pronotum, clavus, a transverse fascia to corium near claval apex, posterior 
portion of outer margin to corium and outer margin and apex of cuneus sanguineous; apical half of the 
second joint of antenne, anterior collar and a central basal spot to pronotum, central base of scutellum, a 
broad central spot to clavus, and basal half of membrane black; scutellum pale luteous, the extreme apex 
black, and the black central base giving it a lunate appearance ; body beneath and legs ochraceous. 
Var. a. Eyes black; scutellum without the black basal spot. 
Var. 6. Resembling var. a, but pronotum without the black basal spot. 
Long. 4 millim. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet, Bugaba (Champion). 
2. Carnus formosus, n. sp. 
Allied to the preceding species, but differing by the more elongate body. Eyes black; anterior collar to pro- 
notum reddish ochraceous ; posterior margin of pronotum pale luteous, with a small central black spot ; 
scutellum with a smaller black central base and the apex concolorous; clavus with the apex only 
sanguineous; corium without the transverse sanguineous fascia; sternum with a black spot between 
anterior and intermediate coxe. 
Var. a. Pronotum with a small black spot on each lateral margin, these spots linearly connected with the basal 
spot. 
Long. 33-4 millim. 
Hab. Panama, Volcan de Aittlan 2500 to 3000 feet (Champion). 
3. Carnus parvus, n. sp. (Tab. XXVIII. fig. 7.) 
Pale ochraceous ; central longitudinal fascia to and base of head, broad subbasal and sublateral fascise, and narrow 
anterior marginal fascia with connecting central fascia to pronotum reddish ochraceous ; clavus and corium
