POMPILID^E 



Salius cabraensis sp. n. — Black, densely covered with a 

 bluish purplish pile, probably ail over with fresh examples, the 

 scape and pedicle of the antennœ dark fui vous, broadly black 

 above, the 3 rd joint fulvous, the other joints are absent; the clypeus, 

 mandibles and labrum dark rufous; wings uniformly dark fuscous 

 violaceous, the stigma and nervures black, the 3 rd abscissa of radius 

 not quite so long as the l st and about half the length of the 2 nd ; the 

 4 th longer than the latter and curved up at the apex; nervellus 

 distinctly post-furcal; the l st récurrent nervure received at the 

 base of the apical fourih, the 2 nd very shortly behind the middle 

 and roundly curved ontwardly, nervellus in hind wings shortly 

 antefurcal. The long spur of the hind tibiœ about one third of the 

 length of the metatarsus; claws with a short broad tooth truncated 

 at the apex; tibiœ and tarsi shortly spinose, the latter more thickly 

 than the former, the basai 3 joints of the hinder densely pilose. cf. 



Length 17 mill. 



The sides of prothorax are broadly rounded; the apex is also 

 broadly rounded, not angled. Sides of metanotum broadly, roundly 

 tuberculate at the spiracles; the apical half is irregularly striated. 

 The eyes converge distinctly below; on the lower three-fourths of 

 the inner orbits they are narrowly lined with brown. There is a 

 distinctly defined furrow on the 2 nd ventral segment; the genitial 

 armature is covered with long black hair. There is no horny point 

 in the discoidal cellule. 



Mayumbe (Cabra). 



Pompilus sepulchralis Smith (Descrip. of New Species of Hymen., 

 145, 17) from Natal appears to be an allied species, but the des- 

 cription, with its lack of structural détails, does not enable one 

 to identify the species; the abdomen is said to hâve a green tinge. 



Salius abdominalis Smith {Pompilus abdominalis Smith. 

 Descr. of New Species of Hymen., 141, Congo). 



A spécimen from Kitobola (Rovere) is, I believe, the çf of the 

 above species. It is 10 mill. long, has the apex of the clypeus 

 depressed and broadly rounded ; the eyes converge distinctly 

 above; the hinder ocelli are separated from each other by a dis- 

 tinctly less distance than they are from the eyes; the apex of the 

 pronotum is bluntly angled ; the metanotum transversely striated, 

 its apex transverse, margined and projecting at the outer edges. 

 The l st abscissa about one quarter shorter than the 2 nd , which is 

 about one fourth shorter than the 3 rd , the latter is about the same
