22 Sir S. S. Saunders' descriptions 



articulate, the basal joints short, the 5th longer, with 

 small claws. 



The female has a short ovipositor like Blastophaga, 

 from which it diverges in the structure of the antennae, 

 which have some resemblance to those of Eupristina in 

 their terminal joints and setose character ; but it differs 

 from the latter in the veining of the wings, which have 

 the cubitus deflexed on the disc, and in its simple 5- 

 serrate mandibular appendages. The head is small and 

 oval, and the mandibles, as well as their appendages, 

 short and broad. The antennae are ten-jointed, the basal 

 joint large and elongate, narrower at the apex, with an 

 angular distension on the inner side ; the 2nd joint 

 longer than broad, and slightly sinuous ; the 3rd forming 

 a long, acute, curvate, projecting spine ; the 4th is 

 shorter than the 5th ; and the 6th to the 9th are cyathi- 

 form, densely clothed with coarse recumbent setae, the 

 6th being more elongate than the others, and the terminal 

 joint fusiform. Thus in these antennae the 3rd and 5th 

 joints of other genera are obsolete. The last four joints 

 are also partially retractile at the base and deeply 

 inserted respectively within the apex of each preceding 

 joint, being occasionally expanded to their full extent, 

 thus imparting a versatile character to these organs, 

 both conditions being sometimes exemplified in the same 

 specimen. 



The thorax is short and gibbous ; the fore wings very 

 elongate, having the post-costal vein widely separated 

 from the costa at its base, but conjoined subsequently, 

 and the cubital vein deflexed on the disc of the wing in 

 a slight outer curve, terminating in an oblong clavate 

 apex. The hind wings have the costa and post-costal 

 vein coalescent and strongly arcuate at thejbase of the 

 wing, extending obliquely beyond the anterior margin, 

 where terminating in a small tubercle bearing two or 

 three hooklets ; the entire disc of all the wings is inter- 

 spersed with short recumbent setae, and surrounded with 

 a deep marginal fringe. The fore and hind legs are of 

 moderate dimensions, and the intermediate pair slender 

 and elongate. The abdomen is oval, about equal in 

 length to the thorax ; the ovipositor short and setiform, 

 not exceeding one-fourth the length of the former beyond 

 its apex, with the sheaths shorter, robust, and falcate. 



The remarkable circumstance of the absence of the 

 middle pair of legs in the males has been consistently
