Hab. Mexico, Orizaba 1 ; Honduras, Ruatan Island (Gaumer). 



A specimen from Honduras (presumably identical with S. chichimeca) has the wings 

 deep violaceous throughout and hardly fainter in tint towards the apex; the apical 

 ventral segments thickly covered with rather long fulvous hair ; and the petiole a little 

 longer than the hind coxse. 



^ 8. Sphex singularis. (Tab. ill. figg. 7, 7 a, s .) 



Sphex singularis, Smith, Cat. Hymen. Ins. iv. p. 261 (<?)*. 



Nigra, longe fuho- vel aureo-hirta ; abdomine sericeo, basi interdum rufo-maeulata ; alis hyalinis, apice 



fumatis. S • 

 Long. 18-21 millim. 



Hab. Mexico, Presidio (Forrer), Teapa in Tabasco (H. H. Smith) ; Guatemala, 

 San Geronimo {Champion) ; Honduras 2 ; Panama, Volcan de Chiriqui 2000 to 3000 feet 

 (Champion). 



Antennae as long as the thorax, thickened towards the apex, covered with a sericeous 

 pile ; the fourth joint scarcely half the length of the third, and shorter than the fifth. 

 Face densely covered with long golden, the front and vertex more sparsely with 

 fulvous, hair ; clypeus almost truncate at the apex ; vertex and front opaque, closely 

 aciculate. Thorax opaque, closely aciculate ; a line on the top of the pronotum, the 

 tubercles, a line at the base of the metanotum, an oblique one along the metapleurse, 

 and a spot on either side of the metanotum, silvery ; the hair pale fulvous, long and 

 dense, especially on the metanotum ; the furrow on the mesonotum shallow ; scutellum 

 convex, without depression in the centre. Petiole a little longer than the hind coxa? ; 

 silvery-pilose, and covered with long pale hair. Abdomen with a bluish tinge, seri- 

 ceous, the base and apex bearing fuscous hair ; the sides at the base of the first and 

 second segments rufous ; a tuft of golden hair on either side of the apical segment. 

 Coxse densely covered with silvery pile, and with long pale fulvous hair ; trochanters, 

 femora, and tibiee sericeous ; calcaria, tibial spines, and the brush at the base of the 

 metatarsus, reddish. Second cubital cellule nearly equal in width at the top and 

 bottom ; the third much narrowed at the top, being there scarcely half the length of 

 the space bounded by the second recurrent and second -transverse cubital nervures ; 

 first recurrent nervure received quite close to the second transverse cubital. 



So far as Smith's description 1 goes, it only differs from the specimens I have 

 described in the third cubital cellule being " subpetiolate."
