New Genera and Species of Rhynchota. 105 
ARTIAZONTES, 0. g. 
Body subovate, depressed. Head armed on each side 
in front of eyes with long spines; lateral lobes much 
longer than central. Antenne five-jointed, simple. 
Rostrum moderate, in type reaching intermediate coxe. 
Pronotum with the lateral margins strongly spined, the 
lateral angles prominent. Scutellum triangular, long, 
apex passing base of membrane. Abdomen not sulcated. 
This peculiar genus I place next to Phricodus, with 
which it agrees in the distinct and remarkable spinous 
structure of the head, but differs in having the antennz 
five-jointed and simple. 
! Artiazontes alatus, n.s. (Pl. IIL., fig. 2.) 
Ferrugineous; head, pronotum, and scutellum with a 
narrow pale central longitudinal luteous line (obscure on 
head). Head with the lateral lobes much longer than the 
central, and armed on each side with five strong spines, 
two apical and three lateral, central lobe somewhat 
indistinctly margined with pitchy; the head is also 
obscurely transversely striated. Pronotum somewhat 
thickly punctate, and strongly and transversely rugulose, 
lateral angles produced into flat processes directed up- 
wards and forwards, with the outer margins finely den- 
ticulated, lateral pronotal margins very strongly denticu- 
lated. Scutellum thickly punctate, somewhat rugulose at 
base. Corium thickly punctate. Membrane cinereous, 
with the nervures pitchy. Underside of body and legs 
somewhat paler than above, femora somewhat spotted 
and streaked with pitchy markings, especially towards 
apex. Antenne with the second and third joints sub- 
equal in length, fourth and fifth also subequal in length, 
but longer than second and third, and fuscous at apices. 
Rostrum almost reaching intermediate coxe. Long. 
11mm. Lat. pronot. angl. 6 mm.
