116 HYMENOPTERA. 



II. Antennas twelve-jointed. Scape compressed, sharp on the lower side ; first joint of 

 the flagellum {after the ring, which is longer than broad) much longer than the 

 second, which is a little shorter than the third ; the rest become shorter and thicker 

 towards the apex. Grooves of the antennas broad, short, forming a hollow above 

 the antennas, not reaching near the ocelli ; vertex a little depressed at the eyes, which 

 are oval and reach to the extreme back of the head and project beyond it laterally. 

 Front before the antennae bluntly keeled. Thorax flat above ; the centre of the 

 mesonotum somewhat depressed. Ovipositor very slightly projecting. 



2. EupelmilS gigas. (Tab. VI. fig. 9, $ ; 9 a, antenna.) 

 Niger, viridi et cupreo tinctis; flagello antennarum (apice excepto) pedibusque rufis; alis fumatis, albo 



fasciatis. 

 Long, fere 9 millim. 



Eab. Panama, Bugaba (Champion). 



Antennae situated a little above the antennal scape, strongly compressed laterally, 

 dilated and hollowed at the side, double as long as broad. Flagellum thick, becoming 

 thicker towards the apex, densely covered with a white pile. Head punctured, pilose. 

 Antennal grooves proper short, broad, ridged on the outer side, converging above into 

 a hollow, which does not reach near to the ocelli. Eyes converging at the top, 

 projecting beyond the back of the head, which is margined on the outer side ; the eyes 

 project above the vertex. Prothorax small. Mesonotum flattish, not raised above the 

 scutellum, centre depressed, with a triangular raised part at the base, the depression 

 bordered with a margin, indistinct at the base, clearly defined towards the scutellum ; 

 on the outside of the mesonotum are two narrow keels, one on the top, the other a 

 little way down the side and running into the tegulae ; there is a transverse, rather 

 wide, groove in front of the scutellum. Metanotum with two wide grooves enclosing a 

 slightly raised part in its centre, and which is widest at the apex. Mesopleura in front 

 eovered with longish white hair, this part being more projecting than the larger hind 

 portion, which is more opaque, and bears only a microscopic pubescence. Abdomen 

 longer than the head and thorax together, smooth, shining, more or less coppery, the 

 apex with a few round obscure punctures, and bearing (as do also the sides) a few 

 longish hairs. Ovipositor shortly projecting, the sheath densely pilose. The coxae are 

 black, more or less green at the base, and covered with a longish hair ; the rest of the 

 legs are densely covered with a close pale pile ; the posterior femora above, the middle 

 tibiae and hind tarsi at the apex, more or less fuscous at the base on the lower side and 

 at the apex. The fore wings are obscure hyaline, more or less infuscated ; and in front 

 of the cubitus, and close to the margin, is a longish hyaline space ; the hind wings are 

 lightly infuscated. 



The largest of the species known to me.
