718 ON HEMIPTEBA-HETEEOPTEEA EEOM ST. VINCENT. [NoV. 21, 



rounded and with a curved spur above in the male ; the outer 

 angle of the dorsal segments is moi'e or less toothed. 



Length to end of abdomen 18-19 millim. ; width of front of 

 pronotum 1 millim. ; width of last segment of abdomen l^-li 

 millim. 



Several specimens of both sexes were secured at various places 

 on the island. Only unwinged ones were found, and three or 

 four of these are in the younger stages. These nymphs are 

 essentially like the adult and differ more in size than in the 

 elements of structure. The form of pronotum and abdomen with 

 the accompanying teeth is nearly the same as in the full-grown 

 specimens. One specimen was found on the leeward side of the 

 island, in September, at an altitude of 2000 feet, and others were 

 captured under logs on the Richmond estate, leeward, in an open 

 valley near sea-level, on October 31. In my collection there are 

 specimens from the vicinity of Panama. 



Emesopsis, gen. nov. 



Form similar to that of Ploiaria, Scop., agreeing therewith 

 especially in the form of the head, but differing in the venation 

 of the hemelytra. Head wide and short, tumidly convex behind, 

 the transverse stricture crossing between the eyes ; the throat 

 unarmed. Rostrum reaching between the anterior coxae ; the basal 

 joint stout, extending behind the line of the eyes ; the second 

 shorter, tumid ; the third slender throughout, shorter than the 

 basal one. Antennae almost setaceous, the basal joint a little 

 stouter, about as long as the head and pronotum united ; the 

 second and third shorter, subequal. The eyes subglobular, placed 

 below the level of the vertex. Anterior tibi?e and tarsi together 

 scarcely shoi'ter than the femora, the femora apparently armed 

 with fine spines throughout nearly the entire length. Pronotum 

 short, the posterior lobe more than twice as long as the anterior 

 one, tumidly convex behind ; the anterior lobe very short, elevated 

 into a callosity each side. Scutellum small, distinct, conical at 

 base, constricted behind, the narrowed portion evenly cylindrical to 

 the tip. Hemelytra membranous throughout, gradually widening 

 towards the tip, the costal margin straight to beyond the middle ; 

 veins of the corium sharply distinct, the transverse ones few, 

 crossing at nearly right angles, the cells growing larger posteriorly, 

 the apex ^\dth a triangular narrow cell at both the outer and inner 

 angle ; cells of the membrane large, the basal one longest, ending 

 in a protracted narrow loop, which sends off a vein to the tip. 

 Abdomen moderately flat, widened towards the middle. 



Emesopsis nubilus, sp. nov. 



Pale f ixlvo-testaceous, elongate, but not linear, smooth above, 

 pilose over most of the surface. Head obsoletely, minutely 

 punctate, the transverse impressed line and a small spot on the 

 middle brown. Antennae setaceous, the last joint infuscated; 

 eyes fuscous. Legs pilose, the intermediate and posterior femora
