DINOCORIS.—EURYSTETHUS. AT 
Hab. British Honpuras, Belize (Blancaneaur) ; Guatemala, La Tinta (Champion).— 
ANTILLES, St. Domingo!; Britis Guiana®; Brazi.?. 
All the specimens examined, including the two identified by Dallas in the British 
Museum, agree with the characters given by Stal as appertaining to this species. 
The base of the fourth and the base and apex of the fifth joint of the antenne are 
luteous, the first and second joints subequal in length, the disk of the abdomen beneath 
castaneous, and the legs pitchy or castaneous. Palisot de Beauvoir describes the colour 
as “‘ presque uniforme.” The specimen figured is from Guatemala.

This genus was founded by Dr. Mayr for the reception of a Brazilian species, which 
he named FE. nigro-punctatus. I have here added another species to the genus, which 
has been received from Panama. The basal joint of the antenne does not reach the 
apex of the head; the second joint is a little shorter than the third ; the lateral lobes of 
the head are reflexed, longer than the central and cleft at apex ; there is a strong spine 
in front of the eyes (Dr. Mayr describes this character, founded on the other species, as 
“denticulo obtuso ante oculos subpetiolatus), the anterior angles of the pronotum are 
produced into transverse spines, and the posterior angles prominent and rounded. 
1. Kurystethus signoreti, n. sp. (Tab. VI. fig. 13.) 
Ochraceous, thickly punctured with brown. Head finely punctate, the lateral margins narrowly impunctate, 
with a central longitudinal impunctate line which does not reach apex. Pronotum rugosely punctate, a 
pale, raised, levigate, transverse line between humeral angles, from which to anterior margin is a pale, 
impunctate, obscure, submarginal line, and one of like character enclosing a large central lenticular space ; 
lateral margins impunctate ; posterior lateral angles rounded, notched behind. Scutellum thickly punctate, 
with a raised convex longitudinal ridge, very broad at the base, and narrowed towards apex. Corium 
thickly punctate, membrane pale ochraceous. Underside of body ochraceous, thickly punctured with 
brown; stigmata pitchy; legs luteous, spotted with brown. Antenne ochraceous; rostrum luteous, just 
passing posterior coxe. 
Long. 8 millim. 
Hab. Panama (coll. Signoret). 
Differs from E. nigro-punctatus, the other species of the genus, by the strong spines
