HETERONOTUS VULNERANS. 
(Plate XXX. fig. 1 ? .) 
Combophora vulnerans, Germ. l.c. p. 228. Ranatra bicornis, Lessing. Fairm. l.cr p. 500, PI. VII. 
fig. 25. Heteronotus stipatus 9 , Walk. l.c. Suppt. p. 155. 
Colour rich purple brown ; pronotum coarsely sculptured and punctured, with a 
creamy white, central longitudinal stripe from the metopidiuin backwards, and 
another on each side over the two suprahumeral spines, the pronotum ending in two 
globose lobes, the posterior expanded in profile into a broad, vertical, fish-tail-shaped 
process, the upper part cleft into two thorns, the lower expanded into a strong ventral 
spine. The middle lobe is the smallest, with a white traverse streak. A similar 
streak occurs on the posterior lobe; tegmina hyaline, ample, with brown costa and 
basal areas ; legs long and reddish ; hind tarsi longest; three basal, two discoidal areas, 
the inner one the largest, five apical areas, of which four are nearly equal and the 
fifth almost atrophied. 
Hind legs with the longest tarsi. 
Fairmaire figures the neuration of the tegmen and divides the nine species he 
names into two groups, viz., those species which have the pronotum longer, and 
those which have the process shorter than the tegmina. 
Size, 10 x 4 mm. 
Habitat. —Mexico, Vera Cruz, Guatemala, Panama, Brazil. 
HETERONOTUS FOWLERI. 
(Plate XXX. figs. 2, 2a, 2b.) 
Colour fuscous grey ; the fore lobe of the pronotum slightly constricted, and then 
behind more suddenly ; the posterior lobe is sometimes attenuated when seen from the 
back, but it is somewhat swollen with a partial constriction into two parts; three 
yellowish parallel streaks occur above, which are confluent below. There are no 
white fasciae on the posterior lobules ; the tegmina are hyaline, slightly fuscous on 
the costa ; the legs are pale. 
I am indebted to Dr. Jonathan Hutchinson for the possession of a small 
collection of Membracidae, made by the late T. W. Wollaston ; from the specimens of 
which I have figured an example. The description given by Fairmaire of Heteronotus 
fiavolineatus of Laporte does not well agree with the above. Heteronotus Fowleri is a 
larger insect, and the yellow strigae on the back differ in number. I think this insect 
is specifically distinct. 
Expanse, with wings, 28 x 13 mm. 
Habitat. —Brazil.
