NEW SPECIES OF BOTHRIOCERA BURM. 
(HOMOPTERA: CIXIIML) FROM THE 
LESSER ANTILLES 
By R. G. Fennah 
Entomologist, Citrus Pests Investigation, Windward and 
Leeward Islands 
In the present paper seven new species of Bothriocera Burm. 
are described. Five of them, B. cyanea , B. phantasma , B. ri- 
paria , B. daedala and B. hastata (see below), are apparently 
endemic in the one island from which each has been recorded: 
another species, B. longistyla , has been found only in two ad- 
joining islands, while the seventh, B. eborea , has, by contrast, 
been taken in all islands where the writer has searched. 
The relation of these species to Greater Antillean or main- 
land forms, and even to each other, is obscure, chiefly on ac- 
count of the difficulty of assessing the value of the available 
morphological or chroic characters. As regards the pattern 
of the tegmina it is evident, from a scrutiny of over 700 speci- 
mens, that within any one island the pattern of a single species 
is constant, even in minute details; between islands, however, 
the differences in tegminal pigmentation of a single species are 
quite distinct, being revealed, not in changes of pattern, but in 
boldness of marking. In the genitalia the shape of the male 
genital styles seems to be a useful character, but forms which 
are allied in the possession of a common type show very differ- 
ent tegminal markings. On the whole, the writer is inclined to 
regard the following group of characters as providing the best 
basis for judging the affinity of Lesser Antillean species: (i) 
truncate styles of the B. hastata type, (ii) a periandrium with 
a process on the left side, (iii) a triangular median ventral 
process on the pygofer and (iv) an anal segment with the apical 
margin rounded. On the basis of possessing at least three of 
these characters all the species discussed below are allied with
