Black, smooth, shining, not punctured ; the head, thorax and abdo- 

 men covered with a white silky down ; the basal joints of the antenna, 

 labrum, clypeus, sides of pronotum, and the apical half of the basal 

 abdominal segment above clear yellow; the fifth all round, a ring on 

 sixth, and (sometimes at the apex, more rarely at base) the ninth above 

 pale yellow. Legs : coxae, trochanters, base of femora and tibiae yellow ; 

 apex of hinder tibiae and tarsi reddish ; anterior tarsi yellowish ; the 

 apical joints and the base of tibiae black or fuscous; femora black, 

 except at base and apex. Tegulae black, white in front. Wings hyaline, 

 scarcely infuscated at the apex ; costa and stigma testaceous, the latter 

 fuscous at the apex. 



The <J has only a narrow yellow stripe on the first abdominal seg- 

 ment ; the fifth, and sometimes the sixth, the belly (save at the apex) 

 and legs are yellow ; apex of the hinder femora, tibiae and the hinder 

 tarsi black. The stigma, too, is darker. 



Length 5? 5f lines. 



Ab. a. The sixth abdominal segment yellow be- 

 neath and above. This is the commonest form in this 

 country; according to the descriptions the sixth 

 segment is only yellow on the upper side. 



Ab. b. Scutellum yellow, entirely or in part. 



This species differs from all the other British Allanti 

 in having the head and mesonotum smooth, shining, 

 and unpunctured. In that peculiarity it agrees with 

 A. zona, Kl., and A. zonula, Klug, but is known from 

 both by having the sixth abdominal segment marked 

 with yellow, and the apex of hinder tibiae and tarsi 

 luteous, both the other species having these parts 

 annulated with black. Zonula is further distinguished 

 from it by having the head scarcely dilated behind the 

 eyes, four anterior legs entirely yellow, the hind 

 femora only black at apex, and the seventh abdominal 

 segment without any yellow band. 



So far as I know it is not very common, and seems 

 to be confined to the south. Mr. Smith took it in
