LIMNOCORIS. 309 
belonging to the Vienna Museum, is figured. It has the posterior angles of the 
connexival segments 2-5 acutely produced behind. ‘The Mexican insect sent to me 
from the Stockholm Museum as L. profundus, Stal,= JL. signoreti, Mont.

Hab. Mexico (Sallé, in Mus. Holm.; Mus. Vind. Ces.1). 
Of this species I have seen a male belonging to the Stockholm Museum, which is 
here figured, and a female from the Vienna Museum ; the last-mentioned specimen is 
very dirty and discoloured. ‘The posterior angles of the connexival segments 2—4 are 
not produced, a character distinguishing this insect at once from Z. stali. 
3. Limnocoris inornatus. (Tab. XXI. fig. 14, 2.)

Hab, GuaTEMALAa (Mus. Hamburg.!), Paso Antonio (Champion). 
The single female example referred to this species, from the “ tierra caliente” of the 
Pacific slope, differs from the description in having the clavus and corium irregularly 
mottled with darker colour, and the connexival segments 3-5 broadly bordered with 
fuscous in front. ‘The posterior angles of the fifth segment only are acute. The 
lateral portions of the metasternum are faintly transversely wrinkled. The type was 
probably discoloured. J. inornatus is very like L. signoreti, but it is smaller and 
smoother; the pronotum is scarcely depressed behind the transverse groove, more 
rounded at the sides, and less narrowed in front; the embolium is more strongly 
sinuate at the sides posteriorly ; and the mesosternal ridge is differently formed.

Hab. Costa Rica, Buenos Aires (Pittier, in coll. Montandon'). 
The type of this peculiar species, a male, has been kindly lent by M. Montandon for 
figuring. The insect is green above, and rounded in outline, with acute posterior 
angles to the pronotum, the eyes broadly margined at the outer angle, the margins 
of the elytra deeply sinuate, and the suture between the clavus and corium indistinct. 
The elytra are without membrane, and there is no trace of wings visible. 
5. Limnocoris insularis, n. sp. (Tab. XXI. fig. 16, 2.) 
Broad oval, opaque, the basal portion of the pronotum and the elytra pale sordid yellow, dotted with fuscous ; 
the rest of the pronotum, the head, and scutellum sordid ochreous, the membrane fuscous; the underside 
and legs flavous, the metasternum and abdomen darker. Head broad, with the eyes almost half the width
