Pangonia oldii is closely allied to P. zonata, Walk, (a 

 Somalilaud species, the type of which is from Tajurrah), but 

 may be distinguished as follows : — In P. oldii the shining 

 callus on each side of the face is longer and less abruptly 

 truncated ; the sides of the second abdominal segment in 

 front of the hind border are clothed with black instead of 

 golden-yellow hair; the hair on the posterior angles of the 

 second and fourth abdominal segments is pure white instead 

 of yellowish ; on the fourth segment these white hairs do not 

 extend to the middle line, whereas the fourth abdominal 

 segment of P. zonata, ? , has a continuous broad hind border 

 of yellowish hair ; on the ventral surface the median portion 

 of the second abdominal segment of P. oldii, $ , is clothed 

 largely with silvery hair, that of the same segment of 

 P. zonata, ? , with yellowish hair ; the ventral surface of 

 the dark segments at the distal extremity of the abdomen of 

 P. oldii, $ , is clothed with black and yellowish hair inter- 

 mixed, while in the case of P. zonata, ? , the ventral 

 surface of the same segments is exclusively clothed with a 

 thick coat of yellowish hair : other differences are to be 

 found in the colour of the legs and hair clothing them. 



Synonymy. 



Pangonia alboatra, Walk. (Ins. Saund., Dipt. i. (1850) 

 p. 13. — Cape of Good Hope), = P. anyulata, Fabr. In 

 AValker's type the white hind border to the second abdominal 

 segment is interrupted in the middle, but the interruption is 

 apparently due to denudation, since, when the abdomen is 

 viewed obliquely from the right front, the hinder border 

 appears to be complete. 



Pangonia mugrettii, Bezzi (Bull. Soc. Ent. Ital. xxxiii. 

 (1901) p. 7. — Eritraea), is, perhaps, merely a dark iorm or 

 subspecies of P. riippellii, Jaenn., the type of which is from 

 Abyssinia.
