[Vol. V,No. 1, 
Head large, ocelli elevated, a little nearer the eyes than 
to each other. Antennae, first joint rather thick extending 
about half the length beyond the apex of the head, second 
joint long, slender, longer than third, third enlarging at 
tip, fourth about as long as third, a little thicker. Pro- 
notum deeply constricted, the anterior- lobe but little 
longer than posterior ; a rather broad granulate collar, two 
conspicuous conical tubercles about as far apart as the 
eyes and situated within naked, impunctate areas; a 
median stripe and lateral lines scantily clothed with 
minute golden hair, posterior lobe distinctly punctate, the 
lateral margins orange and two slightly divergent rather 
diffuse orange stripes on the disk. Scutellum with fine 
golden hair, apex ochreous. Elytra brown, the clavus 
nearly black, margined to beyond its middle with ochreous. 
Corium with a blackish diffused spot towards the base, a 
black band across the centre extending forward in an 
angle. Apex black, the extreme base, a line next to claval 
suture and most of costa yellowish. iMembrane fuscous 
with subhyaline, large spots next to corium at its apex 
and on the middle of the apical line. Beneath black, the 
disk of the abdomen slightly reddish, border of fourth seg- 
ment yellowish, middle portion of the margin light yellow. 
Legs yellow, the anterior femora and tibiae and outer por- 
tion of the femora and tibiae of the intermediate and hind 
legs suffused with fuscous, anterior tibiae distinctly enlarged 
at apex. One specimen from Bartica, Br. Guiana collect- 
ed April IS. It is at once distinguished from any of 
the other members of the genus by the peculiar nipple-like 
tubercles on the anterior lobe of pro-thorax. 
Erlacda arhapheoides Sign. Ouillota Chili, J. C. Hambleton. 
Has ocelli small but well developed. Signoret says, “No 
ocelli” (“Pas d’ocelles”) but in other respects, both gen- 
eric and specific description agrees perfectly. 
Petizius assimilandus Dist. Bartica, Br. Guiana. May, 1901. 
Distant described the species from Guatemala. 
Gonatas divergens Dist. Two specimens from Bartica, Br. Gui- 
ana, agree so closely with this species that I refer them 
here though previous records place it in Guatemala and 
Panama only. 
PYRRHOCORID.t:. 
Dysdercus ruficollis L. Coroica Yungas Bolivia. April. 
C.\PS1D^. 
Lygus cuneatus Dist. Bartica, Br. Guiana. Two specimens. In 
these the apices of femora and tibiae are touched with Ver- 
million or rose and the cuneus is bordered only in part 
with ochraceous.
