E. qiiiurjuelineatus, ¥., is recorded from South Europe, Africa, 

 India, Ceylon and Java. It is readily dif^tingnished from all others 

 in the group of species round arvoriim, F., by the striped eyes, the 

 equally conspicuous median black facial stripe, and to a less extent 

 by the shining black bare stri])e on each side of (he face. The 

 latter character is present in ohscuritarsis, de Meij., but to a much 

 less extent, often being nearly or entirely absent, whilst the median 

 facial stripe is in that species confined to the small central binnp 

 only. E. qidnquelineatus appears to be variable in the relative 

 extent of black and yellow on the abdomen. The arcuate whitish 

 band (usually present in several Indian species) on the 2nd, 3rd 

 and 4tb abdouiinal segments is apparently normally absent on the 

 2nd segment in African specimens, though occasionally it is more 

 or less indistinctly discernible, but it is nearly alwavs present in 

 Indian examples. The 2iid segment is narrowly margined with 

 black, and is dusted with whitish at the base in African specimens, 

 \\hilst in Indian ones the black margin is absent and the whitish 

 dust, replaced by a distinct cupreous tinge. The African form has 

 the spaces between the stripes on the eyes spotted, which is not 

 the case in Indian specimens, excejit occasionally and only towards 

 the margins. The eye-stripes are normally three or four in 

 number, in addition to the usually dark iinier and hind margins, 

 but the number is variable; I have seen a specimen with ilve 

 complete dark stripes in addition to the inner and hind margins. 

 The British JNIuseum contains a long series of the African, i.e. 

 tlie normal, form, showing considerable variability in most 

 characters. 



Frititalonuiia jiaria, Bigot, is I'epresented in the liigot col- 

 lection by three specimens in very bad condition, but their 

 characters are sufficiently clear to prove it synonymous with 

 Erutalis quim/uclineatas. One 2 is labelled " Ceylon," the other 

 two (one headless, the head of the other crushed) bear no data. 

 Bigot's description was drawn up from a J , and fits the insect 

 very badly. An examination of his /'jHsifdomifia zehrina shows 

 that this also is syjionymous with quiw/wlineatns. In tlu^ Cata- 

 logue of Kertdsz, ridens. Walk., is ])laced as another possible 

 synonym, but it cannot be so ; for though the ty])e of it (not now 

 being in the British Mu'<eum) is ])robably lost, seven examples 

 ( d $ ) in the British Museum from China and Corea are identified 

 (probably correctly) as F. ndens, which I consider to be synony- 

 mous with E. tajihici's, Wied. E. fasciatus, 3[eigen, is also given
