the basal segments, as well as the metanotum. The transverse radial nervure is 

 received in the apical fourth of the cellule, and quite close to the third transverse 

 cubital ; the transverse median is received beyond the middle of the cellule ; the 

 accessory nervure in hind wings is shortly appendiculated. The third cubital cellule 

 is longer than the second. The colour of the legs is paler than that of the thorax- 

 Claws simple.

Selandria diversipes, Kirby, List of Hymen, i. p. 189, t. 8. f. 22. 



Hab. Mexico, Orizaba; Costa Eica, Irazu 6000 to 7000 feet (Rogers); Panama, 

 Volcan de Chiriqui 2500 to 4000 feet (Champion). 



The antennae are longer than the abdomen, stout, minutely pilose, the joints (espe- 

 cially the apical) produced at the apices beneath, the third joint longer than fourth. 

 The frontal sutures and the area are subobsolete ; the lower ocellus is bounded behind 

 by a deep triangular furrow ; the foveas are large, moderately deep ; the outer round, 

 with a small tubercle in the centre, the central larger and more irregular in shape. 

 The third cubital cellule is long and narrow, longer than the second, which is a little 

 longer than the fourth, and has a horny point ; the transverse median nervure is 

 received close to centre of cellule. The claws are bifid. The amount of reddish white 

 on the thorax varies. The palpi are blackish in all my specimens ; and the labrum is 

 sometimes black. 



25. Strongylogaster nigricans. 



Strongylogaster nigricans, Norton, Trans. Amer. Ent. Soc. ii. p. 223 ; Catal. p. 155 \ 



Hab. Mexico, Cuantla, Tierra Fria (Saussure 1 ); Guatemala, San Geronimo (Cham- 

 pion). 



Frontal area large, deepest in the centre below the ocellus, truncated at apex at 

 sides, rounded behind ; from the sides at apex runs a ridge in the direction of the 

 eyes ; lateral fovea scarcely indicated, central large. Eyes converging. Third joint 

 of antennas a little longer than the fourth, the middle joints thickened, apex 

 attenuated; second joint longer than broad, not globular. Palpi black. Coxae at 

 base black, the rest white. Posterior femora entirely black, except at extreme base 

 and apex, middle pair lined with black on both sides ; the anterior have more white 

 in front. Apex of four anterior tibiae behind and at extreme apex all round, black ; 

 posterior with apical third black all round. Four anterior tarsi fuscous black, except 

 on metatarsus ; posterior tarsi black, the metatarsus white at base ; spurs black. 

 Wings with a smoky tinge ; transverse radial nervure received very close to third 

 transverse cubital ; third cubital cellule a little longer than second ; transverse median 

 received a little beyond the middle of the cellule.
