200 HYMBNOPTEEA. 



Gastrocoeli transverse, narrower on the inner side. The black on the vertex extends 

 right across and halfway down behind, and in front projects into a sharp triangle. 

 The mesonotum is black to the scutellum ; the latter may be entirely black or have the 

 sides yellow. There is an irregular black mark in the centre of the second and third 

 segments at the base. The anterior tibiae and the apices of the femora have an obscure 

 black line on the upper side. The apices of both wings are broadly infuscated, and 

 there is also, in both, a large fascia before the middle.

This is a variable species so far as the quantity of black on the thorax and abdomen 

 is concerned. It is easily known from /. chiriquensis by the black on the mesonotum 

 being divided, by there always being black on the metanotum, and by the stigma being 

 yellow, 



B. Areolet quadrangular, large, a little longer than broad, scarcely angled in the middle, 

 where the recurrent nervure is received ; gastrocoeli semiobsolete ; abdominal segments 

 not striated.

Hab. Panama, Bugaba (Champion). 



Antennae as long as the body, of the usual form ; the scape yellow on the lower side. 

 Head impunctate ; the tips of the mandibles, the vertex in the centre in front and 

 broadly behind, black. Pro- and mesothorax impunctate, shining. Metanotum trans- 

 versely striated, except in the centre behind, and without distinct tubercles. Scutellum 

 keeled along the sides. Abdomen a little longer than the head and thorax ; the apex 

 obliquely truncated and a little compressed laterally. Petiole smooth, impunctate; 

 the other segments obscurely aciculate. Gastrocoeli semiobsolete. The sheaths of the 

 ovipositor originate from the bottom of the venter and are directed obliquely upwards,, 

 projecting above the top of the dorsum. 



ABZARIA 



Eyes margined; two, slightly curved, compressed laterally, a little dilated at the 

 apex, tubercles on the hollow above the antennae. Scutellum not margined. Petiole
