428 HTMENOPTEEA. 



a. Parapsidal furrows distinct. (Species 5-12.) 

 1. Badial and cubital nervures more or less distinct. (Species 5-11.) 



5. Evania albispina. (Tab. xvil. fig. 18, s .) 



Nigra, facie, ore spinisque albis ; fronte rugosa ; petiolo striolato ; coxis posticis rugoso-punctatis ; alis fere 



hyalinis. $ . 

 Long, fere 8 millim. 



Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 



Antennae with the scape not much longer than the third joint, the latter, if anything, 

 shorter than the fourth joint. Head broad, almost transverse, not keeled in the centre 

 of the face ; the front not depressed. Face punctured, strongly so laterally ; the front 

 closely punctured. Mesonotum transverse in front, flat, shining, very minutely punc- 

 tured, shining, the lateral lobes obscurely striated in front ; parapsidal furrows shallow, 

 the lateral furrows deeper. Mesopleurae and sternum roughly punctured, except a 

 shining impunctate space in the middle of the former. Scutellum coarsely striated. 

 Metathorax rugosely reticulated. Petiole shining above, with some large shallow 

 punctures towards the apex ; the sides bear some stout striations, which go on to the 

 top at the apex ; the apex is dilated. The hind coxae are opaque and coarsely punc- 

 tured ; the spurs are three fourths of the length of the metatarsus ; the tarsi bear 

 scattered stiff bristles ; the metatarsus is shorter than the second and third joints united. 

 The face, the pleurae, and metanotum are covered with rather long white pile ; the rest 

 of the thorax is more sparsely clothed with fuscous pile ; the coxae are covered with 

 rather long white pile, the femora sparsely on the underside, and the tibiae and tarsi 

 thickly, with a fuscous pile. The underside of the scape, and the fore coxae, trochanters, 

 femora, and tibiae are whitish in front. 



6. Evania maximiliani. 



Evania maximiliani. Schletterer, Verh. zool.-bot. Ges. Wien, xxxvi. p. 28 (1886) \ 

 Hab. Mexico, Orizaba (Bilimek 1 ). 



This species may be known from E. albispina by the spurs being one third of the 

 length of the metatarsus, besides being black, and the hind coxae are not punctured. 

 E. rugifrons differs from it in the pleurae being rugosely reticulated, except a small 

 space below the fore wings, and in the front being keeled and the hind coxae 

 punctured. 



7. Evania rugifrons. (Tab. XVIL fig. 19, s .) 



Nigra, mandibulis albo-testaceis ; facie et fronte rugosis ; coxis posticis punctatis ; petiolo laevi. «? . 

 Long, fere 7 millim. 



Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion).
