l. Balna nigriceps. 



Eufa ; capite, scapo antennarum abdomineque nigris, alis hyalinis. 



Long. 3-4 millim.

Hab. Guatemala, Volcan de Atjlan 2500 to 3000 feet (Champion). 



The antennae are as long as the body, filiform, becoming very slightly thicker towards 

 the apex ; third joint a very little longer than the fourth, the rest to the penultimate 

 becoming gradually shorter, the last one half longer than the twelfth ; the first double 

 the length of the second, which is broader than long. Vertex raised, its centre hollow. 

 Head broad behind the eyes, where there is a suture. Prothorax ridged, the ridge 

 scarcely sloping towards the coxse, with a very slight slope in front, and ending in the 

 centre in a small blunt tubercle. Lateral suture on mesonotum deep, ending at the 

 prothoracic ridge, middle suture short. In the middle of the mesonotum is a blunt, 

 comparatively large, tubercle. A ridge separates the scutellum from mesonotum ; it 

 has one large hollow at the base, and has a sharp blunt ridge in the centre ; it is hollow 

 on either side of this and ends in a short, blunt spine, but the ridge is depressed before 

 ending in the spine. The pleurae are smooth, impunctate. The metanotum is thickly 

 covered with white hair. 



NERALSIA. 



Antennae 13-jointed, thick, increasing in thickness towards the apex; first joint 

 double the length of second, which is ovate ; third longer than fourth ; the sixth to 

 the penultimate thicker than preceding, a little longer than broad, rounded at base 

 and apex, striated ; last nearly double the length of twelfth. Eyes bare, margined. 

 Ocelli in a triangle. Pronotum margined, very nearly perpendicular in front. Meso- 

 notum smooth, shining, with two sutures ; scutellum with two large fovea? at the base, 

 prolonged into a moderately long spine at the apex. Petiole striated. Radial cellule 

 not much longer than broad, completely closed all round. Cubital nervure incomplete, 

 apex of wing ciliated. Mandibles stout, not much longer than broad, with three short 

 blunt teeth. Maxillary palpi 4-jointed. 



This genus is intermediate between the Onychiina and the Figitina. It agrees 

 with the former group in the structure of the thorax and abdomen, with the latter in 

 the form of the antennae. The almost moniliform joints of the latter distinguish it 

 from any of the known genera of Anacharina. 



1. Neralsia mfipes. (Tab.IV. figg.9$; 9a, antenna; b, scutellum; c, ovipositor.) 



Nigra, abdominis basi pedibusque rufis ; alis hyalinis, medio fusco-maculatis. 

 Long. 3-4. 



Hab. Guatemala, Pantaleon 1700 feet (Champion). 



The antennae are as long as the abdomen and half the thorax, slightly pilose, the 

 hairs long and scattered; basal joint three times as long as the second, thickened
