as the metatarsus; claws cleft, the basal tooth shorter and thicker than the apical. Basal 

 3 joints of antennal llagellum of equal length, the scape bearing long blackish hair. 

 Ocelli in a curve, the hinder separated from the eyes by a greater distance than they 

 arc from each other. 



Pompilidae. 



Salius, F. 



I use the generic names, as a matter of convenience, of the Pompilidre, as defined 

 by Dr. ROBERT LUCAS, in his paper on the Pompilid;e of East Africa, p. 57. The species 

 enumerated here may be separated by means of the following table. 



1 (6) Claws cleft, the basal tooth dilated, shorter than the apical. CypJiononyx. 



2 (3) Apex of wings broadly yellowish hyaline, the basal 5 joints of antenna; rufous. 



Caroli- Waterhousi. 



3 (2) Wings uniformly fuscous violaceous, the antennae entirely black. 



i (5) 2nd abscissa of radius distinctly longer than the 3rd, the 2nd recurrent nervure received distinctly 

 before the middle of cellule, the anal nervure in hindwings almost interstitial. 



melanoceras. 



5 (1) 2nd abscissa of radius equal in length with the 3rd, the 2nd recurrent nervure received before 



the middle of cellule, the anal nervure in hindwings distinctly before the cubitus. 



momboensis. 



6 (11) Claws with one tooth. Priocnemis. 



7 (10) Small species, wings hyaline. 



8 (9) Head and llagellum of antenna 1 black, lower inner orbits lined with white, albolineatux. 



9 (8) Head and antenna? rufo-testaceous, the orbits not lined with white. cmmectens. 



10 (7) Largo species; wings dark fuscous, with lighter patches towards the apex, fuscofasciatus. 



11 (6) Claws with more than one tooth; the 2nd recurrent nervure received close to 2nd transverse 



cubital. Mygnimia. 



12 (15) Head and thorax black. 



13 (14) Antenna; and legs rufo -testaceous, abdomen more or less rufous. prodigiosus, GERST. 

 14? (13) Antenna; and legs and abdomen black. vindex SM. 



15 (12) Head, pronotum, mesonotum and more or less of pleura; rufo-testaceous. Tamiseri, GUKR. 



It is evident that the Powpilifhc are well represented in Tropical Africa. Un- 

 fortunately the smaller species are almost unknown. 



Ol>s. The name 8alius is preoccupied in Coleoplera. Mr. A. SCHULZ (Hym. Stud., 

 24) proposed that it should lie replaced by Cryptochilus, BIELBERG. 



Salius (Cyphoiiouj-x) Caroli-Waterhousi, sp. nov. 



Black, the basal 5 joints of the antenna? and the legs, except the coxae, tro- 

 chanters, base of femora broadly and the apical half of the last joint of the claws, rufo- 

 ferruginous; the wings to near the middle of 1st cubital cellule fuscous violaceous, with 

 brilliant violaceous and brassy tints, the rest ferrugineous; the 2nd abscissa of radius 

 a little shorter Hum the 3rd; the 3rd transverse cubital nervure roundly curved in front
