432 HYMENOPTERA. 



Antennae with the scape nearly as long as the third and fourth joints united ; the 

 third joint longer than the fourth, and nearly three times the length of the second joint. 

 Face densely covered with stiff silvery-white pubescence, rugosely punctured, nearly 

 transverse. Front densely pilose, the pile not so long as that on the face but closer, 

 keeled down the centre, rugosely punctured ; the vertex is not so strongly punctured, 

 and has the punctures more widely separated. Collar almost transverse, but projecting 

 a little in the middle. Mesonotum shining, the middle lobe marked with large distinctly 

 separated punctures ; the lateral lobes impunctate, a wide shallow furrow down the 

 centre ; parapsidal furrows narrow, moderately deep. Scutellum punctured. Pleurae 

 rugosely punctured, the punctures running into reticulations ; a large shining impunctate 

 space below the fore wings, and a smaller one below the hind wings. Metathorax 

 rugosely punctured. Petiole double the length of the metanotum, smooth, shining, 

 impunctate. Hind coxae punctured ; spurs reaching to the middle of the metatarsus, the 

 latter scarcely so long as the following three joints united. The four anterior legs 

 are more or less obscure brownish in front ; the anterior trochanters are almost entirely- 

 white, the posterior pair having only the basal half white. 



B. Badial and cubital nervures obsolete. Antennas with the third joint not more than 

 double the length of the fourth ; the other joints not much shorter than the third. 

 Parapsidal furrows obsolete. Metatarsus generally longer than all the other joints 

 united. Body more or less red. (Species 14-18.)

Eab. Guatemala, Duenas (Champion). 



Antennae with the scape scarcely so long as the following three joints united ; the 

 second joint a little longer than the fourth, and shorter than the third. Head rugosely 

 punctured throughout, the punctures coarsest on the face, sparsely covered with 

 glistening white hair. Thorax above coarsely rugosely punctured ; the pro- and 

 mesopleurae shining, punctured only on the lower side. Metapleurae reticulated, the 

 reticulations elongated in front. Petiole one half longer than the metanotum, shining, 

 sparsely punctured, and sparsely pilose. Hind coxae impunctate ; spurs reaching to 

 the middle of the metatarsus, the latter longer than all the other joints united.
