CICADELLINAE: PART 2. NEW WORLD CICADELLINI 341 
carina at transition from crown to face, in its symmetrical paraphyses in the 
male (asymmetrical in Diedrocephala) and in the produced sternum VII of the 
female (concave in Diedrocephala). 
Specimens belonging to Ladoffa have been seen from southern Mexico to 
Bolivia and southeastern Brazil and Argentina. Little is known of the biology 
of the species, but L. dependens, n. sp., has been collected on cacao in Guate- 
mala and intercepted from a banana cargo from Guatemala. L. sannionis, n. 
sp. and L. elauta, n. sp., have both been collected on cacao, in Guatemala and 
Costa Rica respectively, and the former also on sweet lemon in Costa Rica. 
There are three female specimens of Tettigonia coccinea Fowler in the British 
Museum. I have identified a male (fig. 294) from a specimen compared with 
two of these. 
Only two specimens of Tettigonia guttata Signoret have been seen; the lecto- 
type, which is without an abdomen, and a molded specimen with abdomen 
and wings missing. It is possible that one of the new species, below, should 
bear the Signoret name, but none of them seem to agree well with the original 
illustration, as did the lectotype. 
There are nomenclatural difficulties relating to Cicada sanguinolenta Co- 
quebert. I overlooked Fabricius’ (1803a:67) reference to Coquebert’s earlier 
work while working with the Fabrician types in Copenhagen, and in the belief 
that Fabricius was proposing a new species, I selected a lectotype of Cicada 
_ sanguinolenta Fabricius (Young 1965c:16). But the ‘“‘lectotype”’, which fits 
Sp 
Fabricius’ description, and which I sketched, apparently does not fit the 
original description (the original illustration is of no value as far as species 
identification is concerned) of Coquebert, but agrees with specimens I studied 
subsequently from British Guiana, and which are conspecific with the holo- 
type of Tettigonia ignota Walker, which is the oldest available name, since 
Cicada sanguinolenta is preoccupied (in Cercopidae). The Coquebert sanguinolenta 
is not renamed here, because its identity is unknown and likely to remain so. 
Dr. Metcalf (1965a:405) used rubriguttata Walker as the oldest available name 
for the species treated here as ignota (Walker), but a female specimen which I 
compared with the lectotype of rubriguttata belongs to another species, which is 
keyed and illustrated below. 
The present interpretation of Tettigonia purpurascens Fowler is based on 
specimens which agree well with the original illustration of that species.
