58 HEMIPTERA-HOMOPTERA. 
very distinct; at first sight it looks like a brightly-coloured form of a darker insect, but 
this is probably not the case. The specimens are not immature. 
9. Stictopelta lineifrons, sp.n. (Tab. V. figg. 3, 3a, 4.) 
Parva, elongata, griseo-virescens, lineis quibusdam brunneis transversalibus plus minusve interruptis trans 
caput metopidiumque ductis, et limbo laterali pronoti ab humeris usque ad apicem albescenti, colore 
nonnunquam indistincto; pronoto angustiori, subtiliter punctato, ad apicem sensim acuminato, humeris 
obtuse prominulis; tegminibus hyalinis ad basin testaceis, ad apicem fuscis, venis brunneis vel nigro- 
brunneis ; pedibus testaceis. 
A small narrow species, of a greyish-green colour, with the head and metopidium lighter, often yellowish, with 
four or five dark, narrow, transverse, more or less irregular bands, and with the border of the pronotum 
from behind the shoulders to the apex whitish or greenish-white ; the colour is sometimes very distinct 
and sometimes almost merged in that of the pronotum ; the pronotum is elongate and gradually narrowed 
to the apex, finely punctured and very finely alutaceous between the punctures; the tegmina are 
hyaline, somewhat fuscous at the apex, with the veins blackish-brown or brown, and the marginal vein 
towards the base black; legs testaceous ; segments of the abdomen with the apical half testaceous. 
Long. 64-73 millim., lat. int. hum. 34 millim. 
Hab. Mexico, Temax in North Yucatan (Gawmer). 
Thirteen specimens. This is one of the most distinct species of the genus that I 
have seen; the venation of the wings is that of a typical Stictopelta. 
10. Stictopelta incerta. 
Darnis incerta, Walk. List of Homopt. Ins., Suppl. p. 1497. 
Ochrolomia incerta, Butl. Cist. Ent. ii. p. 388°. 
Hab. Mexico (Sallé!), Atoyac in Vera Cruz (Schumann), Temax in North Yucatan 
(Gaumer). 
11. Stictopelta nigrifrons, sp. n. (Tab. V. figg. 4, 4a, b.) 
Brevis, latior, testacea, tertid vel quarté parte anteriori pronoti, maculis quibusdam testaceis supra caput 
exceptis, nigré; pronoto rotundato, plus minusve distincte punctato, humeris obtuse prominulis, apice 
haud abrupte acuminato, interdum fere rotundato; corpore subtus et pedibus testaceis. Pracedenti 
affinis, sed colore facillime distinguenda. 
Very like the preceding, but on an average smaller and easily distinguished by its colour, the front part of the 
pronotum being black—the colour being sharply defined and usually reaching for about a third part of the 
whole surface from the front of the metopidium ; sometimes the metopidium only is black, and there are 
always a few larger or smaller testaceous markings just aboye the head, which, with. all the rest of the 
insect, is testaceous. 
Long. 64-7 millim. ; lat. int. hum. 4 millim. 
Hab. Mexico, Temax in North Yucatan (Gawmer). 
Four male specimens. JS. nigrifrons may possibly be a variety of the male of the 
preceding species, but I have not noticed any other colour-varieties of the same sort in 
the group.
