It is important to note that the forms belonging to the two 
above-defined groups seem to be in a very different condition. 
The forms of the ericetorwm-group are less differentiated, so that 
I am able to recognise practically a single species, divided into 
many varieties, which inhabits mainly the centre and the north of 
the Ethi iopian Region, and besides extends throughout the Oriental 
Region. The forms of the rostrata- group are more differentiated, 
showing often very striking characters, such as hairy eyes, pro- 
jecting tae! &e., so that I can distinguish five species, which are 
more dominant in the south, with the notable exception of a species 
( fiorzi) which reaches the north of Italy; species of this group are 
wanting in the Oriental Region. 
15. Asarcina ericetorum, Mwhriccus (1781). 
This species is at once distinguished by the wholly yellow, less 
projecting face, by the approximate antenne, and by the cariniform 
facial tubercle. 
A very variable species, which I can at present subdivide into 
the following six Ethiopian forms, of which gemmata, usambar- 
ensis, and typica are apparently very closely related, while the 
others seem to be all very distinct. 
(a) typica, Bezzi (1908). 
Distinguished by its clear wings, mainly pale-haired seutellum, 
the unconstricted first abdominal yellow band, and the linear black 
bands.

9. vii. 1907 (Dr. W. M. Graham).
