230 HEMIPTERA-HOMOPTERA. 
Stal’s other characters do not appear to be constant. He speaks of the vertex of the 
head, for instance, as being furnished with two testaceous spots at the base, but these 
are only present in some specimens, and in one example, a female, in which they are 
very conspicuous, and in which the other characters agree with Stal’s description, the 
last segment of the abdomen is abnormally shaped, being deeply and narrowly raised 
in the centre, with the central portion forming a small raised horizontal prominence ; 
in fact, if the formation of the segment is to be taken as a specific character, this 
specimen might well be referred to a different species, and yet it must be treated, I think, 
as specifically identical with the other examples from the same locality (Omilteme). 
It is probable that the Tettigonia funebris of Signoret, from California, is identical 
with O. tartarea, as there is a specimen in the Vienna Museum labelled with both 
names ; if such be the case, Signoret’s name must be substituted, unless both are 
finally referred to O. obtusa after the examination of a larger amount of material. 
A specimen from Omilteme is figured. 
7. Oncometopia fuscipennis, sp. n. (Tab. XIV. fig. 16.) 
O. obtuse affinis, sed brevior et latior, nigra; capite et pronoto fuscis, obscure variegatis, illo lato, hoc longitudine 
sesqui-longiori, rugose punctato; scutello magno; tegminibus usque ad apicem fusco-hyalinum fusco- 
brunneis; corpore subtus pedibusque fusco-piceis, illius marginibus dilutioribus, nonnunquam flaves- 
centibus. 
Very like O. obtusa, but shorter and broader in proportion, black, with the front parts more or less obscurely 
variegated with reddish-fuscous ; head short and broad; tegmina of a fuscous-brown colour, with the 
apex, which is usually clear hyaline, also fuscous, though transparent, and with a more or less distinct 
transparent spot (sometimes obscure) about the middle ; sides of the body lighter, sometimes light yellow, 
and probably of this colour in all specimens in life. 
Long. 18 millim. ; lat. ad hum. 4 millim. 
’ Hab. Mexico, Soledad and Chilpancingo in Guerrero 4600-5500 feet (H. H. Smith). 
An example from Chilpancingo is figured. 
8. Oncometopia quadrinotata, sp.n. (Tab. XIV. fig. 17.) 
Precedenti valde affinis, sed tegminibus nigro-fuscis quatuor maculis lete rufis instructis precipue distin- 
guendus. 
Very closely allied to the preceding (0. fuscipennis) and, like it, differing from O. obtusa in its shorter and 
proportionately broader form; the tegmina, however, are darker, and at the base and outer margin of 
each, towards the apex, there is a bright red patch, which gives the insect a very distinct appearance ; 
the sides of the body are a light testaceous-yellow. 
Long. 14 millim.; lat. ad hum. 4 millim. 
Hab. Mexico, Jalisco (Schumann). 
I have also referred one or two other specimens doubtfully to this species, as they 
resemble it in shape and in the colouring of the tegmina, but have the red spots 
indistinct or absent. They are all from the same locality.
