SIPHONOPHOEA OLIVATA. 
165 
Very large. Head and thorax black. Abdomen 
olive-green or reddisb-brown, with black lateral spots 
on the Carina, and black tubercles. Slightly hirsute. 
Tail very long, ensiform, luteous or pale green. An- 
tennse very long, greenish. Legs much as in the 
larva. Cornicles long, thick at the base, and curved. 
Wings ample. Membranes slightly olive, very slightly 
iridescent. Insertions and stigmata pale greenish. 
Veins fine, brownish. Rostrum long, reaching to the 
third coxse. The sternum and anal plate black. 
Very numerous at Lynchmere, Sussex, crowding on 
the flower-stalks of the thistle, Garcluus lancevlaMs, 
during the middle of August. 
I can find no description of this insect by former 
observers. Also I am unable certainly to say that it 
is A. cardtdna of Walker, which has green cornicles 
and a green flat body. 
Genus II. — PHORODON,^" Passerini. 
Rostrum moderately long, reaching to the second 
coxa3. 
Antennse hardly longer than the body. First 
joint bluntly toothed or gibbous. Third joint the 
longest. Fourth and fifth joints nearly equal. Vertex 
flat. Frontal tubercles each with a strong character- 
istic tooth developed on their inner sides. 
Cornicles long, cylindrical, and slightly clavate. 
Cauda short. Legs also short. 
Wings moderately long, with venation as in Siphono- 
johora. 
N.B. — The porrected frontal tubercle, taken by itself, 
is of no generic import, as it may be found in the males 
of some other genera. Its presence has its signifi- 
cance only when it accompanies the gibbous form of 
the first antennal joint.
