218 . HEMIPTERA-HOMOPTERA. 
8. Aulacizes sparsa, sp.n. (Tab. XIII. fig. 17.) 
A. piperate similis, sed major, vertice magis producto, triangulari, et corpore supra multo densius maculis 
parvis asperso, facile distinguendus; capite nigro, maculis parvis testaceis; metopidio testaceo, nigro- 
variegato; pronoto rugose punctato, basi ante scutellum leviter sinuata, hoc et tegminibus dense flavo- 
testaceo aspersis; scutello nigro, macula magna ad basim flavescenti; tegminibus ad apicem haud 
hyalinis ; corpore subtus dilute testaceo, abdomine ad medium nigro; pedibus testaceis. 
Larger than A. piperata, which it resembles, and easily distinguished by its triangular head, the denser and 
larger testaceous markings, which cover the whole upper surface, the large yellow spot on the scutellum, 
and the opaque apex of the elytra; the markings on the pronotum, which is rugosely punctured, are more’ 
or less confluent, and the apex and extreme base are darker than the central portion; the general colour 
is a rich castaneous brown, the underside (with the exception of a black line down the centre of the 
abdomen) and the legs being light testaceous. 
Long. 13 millim.; lat. ad hum. 4 millim. 
fab. Guatemata (Mus. Holm.). 
A single female of this very distinct species was sent to me by Dr. Aurivillius among 
some unnamed insects belonging to the Stockholm Museum. 
9, Aulacizes pollinosa, sp.n. (Tab. XIII. fig. 18.) 
Precedenti affinis, sed angustior et magis parallela, capite longiori, oculisque minus prominulis, corpore supra 
multo densius maculis minutis testaceis irrorato. 
Allied to the preceding (A. sparsa), but narrower and much duller, with the head larger and more pointed, and 
the eyes less prominent ; pronotum less rugose ; upper surface much more thickly sprinkled with minute 
whitish or testaceous spots, which are more separated on the pronotum; apex of the scutellum testaceous ; 
metopidium mostly yellow ; chest and abdomen darker in the centre, lighter at the sides; legs reddish, 
the femora variegated with testaceous. 
Long. 13 millim.; lat. ad hum. 32 millim. 
Hab. Mexico (Bilimek, in Mus. Vind. Ces.). 
A specimen of this species has been sent to me from the Vienna Museum collection 
as Tettigonia irrorata (Fabr.) (Ent. Syst. iv. p. 33; Sign. Ann. Soc. Ent. Fr. 1855, - 
p. 59, t. 6. fig. 14 = Aulacizes rufiventris, Walk. List of Homopt. Ins. iii. p. 796), 
which is a common Brazilian insect ; but it differs from a typical example of Signoret 
sent with it in the shape of the head and eyes, narrower form, and different coluration, 
and is, I think, without doubt distinct. 
10. Aulacizes aurantiaca. (Tab. XIII. fig. 19.) 
Tettigonia aurantiaca, Sign. Ann. Soc. Ent. Fr. 1855, p. 225, t. 6. fig. 17°.

Hab. Mexico! ? (Sallé, in Mus. Brit.? ; Mus. Vind. Ces.); Guatemata, San Gerénimo 
(Champion). 
The type-form of this species is of a deep orange-red colour. The single specimen 
in our collection, from Guatemala, and from which our figure is taken, is yellow, and
