102 HYMENOPTEKA. 



3 (2) . Scutellum ending in processes which are as long as tke abdomen. An- 



tennae in male flabellate. 



4 (5). The third joint of antennae as long as all the succeeding joints together. Lirata. 



5 (4) . The third joint not much longer than fourth Kapala. 



LIRATA. 



Antennae 10-jointed, simple, pilose ; the third joint nearly as long as all the succeeding 

 together ; all the joints thicker at the apex than at the base. Scutellum hollowed in the 

 centre above, and having at the apex two thickish curved spines, which reach nearly to 

 the apex of the abdomen, and not projecting beyond the wings when these are folded 

 along the sides. Metathorax simple, without tubercles. Petiole nearly as long as the 

 abdomen, stout, cylindrical. 



The very long third joint of the antennae enables this genus to be known from 

 Thoracantha and Kapala. 



1. Lirata luteogaster. (Schizaspidia luteogaster, Tab. V. fig. 16 ; 16 a, 

 antenna.) 



Nigra ; pedibus scapoque antennarum flavis ; abdominis apice lsete luteo ; alis hyalinis. 

 Long. 6 miUim. 



Hab. Panama, Island of Taboga {Champion). 



The antennae are nearly as long as the abdomen, become slightly thickened towards 

 the apex, and are covered with closely pressed hairs. The apical joints are shorter 

 and more distinctly separated than the basal ; the last joint is double the length of 

 the preceding. Head covered with waved reticulations ; the vertex in the middle is 

 depressed, opaque, and obscurely reticulated. Thorax covered with more or less waved 

 reticulations all over, and sparsely with longish black hairs ; at the base, in the centre, 

 the mesonotum is depressed, the depression being smooth and shining, much longer 

 than broad, and narrowest at the apex. Scutellum broadly depressed in the centre, 

 finely aciculated. The processes of the scutellum converge slightly at the apex ; they 

 are thick, closely and coarsely transversely striated, and are longer than the head and 

 thorax together, being as long as the antennae. Petiole thick, transversely striated, and 

 somewhat longer than the rest of the abdomen, which is strongly compressed, a little 

 longer than broad, and, if anything, longer than the abdomen. Coxae black, obscurely 

 striated.

In this genus the antennae are 11-jointed ; the joints short, the third and fourth 

 subequal, scarcely longer than the others ; the joints of the flagellum in the male bear
