are more pilose than they are in E. cingulatus, and not so much thickened towards the 

 apex. The antennal grooves are wider and deeper. 



BRASEMA. 



Eyes hairy, converging at the top. Front hollow, and with a somewhat triangular 

 projecting space above the antennae ; the hollow is scarcely ridged at the bottom. Head 

 not dilated at all behind the eyes. Mesothorax raised into a peak, above the centre of 

 which depressed. Mesonotum hollow in the centre; scutellum narrow at the base. 

 Abdomen long, narrower than the thorax ; segments two to six subequal, transverse ; 

 apical segment shorter and narrower. Ovipositor as long as the two last segments 

 together. Middle tarsi dilated, setose beneath. 



The short, not incised, second abdominal segment distinguishes this genus at once 

 from Lutnes ; the hairy eyes from Eupelmus. 



1. Brasema brevispina. 



.Nigra ; trochanteribus, coxis intermediis, geniculis, tibiis intermediis, posticis medio tarsisque testaceis ; alis 



hyalinis. 

 Long. 4 millim., terebra fere 1 millim. 



Hab. Guatemala, Pantaleon 1700 feet (Champion). 



Head opaque, slightly punctured, the face covered with a white pile. Thorax 

 alutaceous ; pilose in front, behind, at the sides above, and on the sternum ; pleurae 

 glabrous, finely punctured. The sides and apex of the abdomen are covered with a 

 white pubescence ; apex very minutely and sparsely punctured, almost opaque ; the 

 base more shining. Mesonotum distinctly margined all round, the border going round 

 the scutellum ; the centre deeply hollowed, the sides of the hollow having a well-defined 

 border, which becomes better marked as it reaches the outer border at the scutellum ; 

 the centre of the hollow is raised into a somewhat triangular posture, which is prolonged 

 behind into a narrow keel. On the thorax, above the fore wings, are two tubercles at 

 the end of the central carina of the mesonotum and close to the end of it, one close to 

 the carina, the other below it. The abdomen is narrower than the thorax, longer than 

 the thorax and the head together, the centre depressed, the apex bluntly pointed ; apex 

 of the terebra testaceous. The antennas are a little shorter than the abdomen, rather 

 thin, becoming thicker towards the apex ; the scape is curved, finely keeled on the lower 

 side ; the third joint is a little shorter than the fourth and nearly as long as the fifth, 

 the fifth a little longer than the sixth. 



LUTNES. 



Eyes hairy, converging above. Antennae inserted in the middle of the face. Front 

 hollow below the ocelli, projecting between the antennae, ridged on the lower side. 

 Scutellum narrow at the base, almost pear-shaped. Abdomen subsessile; second
