EVANIA. 431 



distinct. Scutellum rugosely punctured. The lower part of the mesopleurae and 

 sternum strongly punctured, the upper part finely punctured, the oblique depression at 

 the end obliquely striated. Metathorax rugosely reticulated. Petiole shining, impunc- 

 tate, about one and a half times longer than the metanotum. Hind coxae finely punc- 

 tured ; spurs reaching nearly to the middle of the metatarsus. The legs are rather 

 long ; the coxae are obscure white, black at the base and apex ; the trochanters are 

 white, black at the apex, the posterior pair broadly so ; the hind femora, tibiae, and 

 tarsi are black, the femora obscure brown in the middle. The mesonotum laterally 

 and the metanotum in the middle are obscured with black. 



2. Badial and cubital nervures entirely obsolete. (Species 12.)

Rufa, lsevis, antennis, metathoraee postice, abdomine pedibusque postieis nigris, apice petioli facieque albis :

 Long. 4-5 millim. 



Hab. Panama, Bugaba {Champion). 



Antennae issuing from near the middle of the eyes ; scape scarcely so long as the 

 second and third joints united ; the third joint about three times the length of the second 

 and slightly shorter than the fourth joint. Face projecting in the middle, obscurely 

 punctured ; the vertex more closely and strongly punctured. Pro- and mesothorax 

 shining, impunctate ; the middle lobe raised; the parapsidal furrows wide, deep; 

 mesopleurae deeply obliquely excavated, very shining. Scutellum shining, impunctate, 

 the space in front of it crenulated. Metathorax rugosely punctured ; the apex with 

 an oblique rounded slope, black ; the metapleurae hollowed, shining, obliquely striated 

 round the edges, the centre being smooth. The thorax is almost glabrous. Petiole 

 more than double the length of the metanotum, shining, impunctate. The four anterior 

 legs are pale reddish-testaceous, the middle femora blackish above. The hind legs are 

 black, except the greater part of the coxae and the base of the trochanters ; they are 

 sparsely covered with white hairs, the tarsi densely so. The long spur on the tibiae is 

 more than one third of the length of the metatarsus, the latter being a little shorter 

 than the other joints united. Tarsi longer than the tibiae, the joints elongated, the 

 basal pair as long as the tibiae. 



b. Parapsidal furrows obsolete. Cubital nervure obsolete beyond the first 

 cubital cellule. (Species 13.) 



13. Evania trochanterata. (Tab. XVII. fig. 23, $ .) 



Nigra, rugosa, punctata ; pro- et mesothorace rubris, antennarum articulis 2°-4 m , trochanteribus, spinis petioli- 



que dimidio apicali albis ; petiolo laevi ; alis byalinis. $> .
