222 HEMIPTERA-HOMOPTERA. 
4, Phera nitida. 
Tettigonia nitida, Sign. Ann. Soc. Ent, Fr. 1855, p. 799, t. 24. fig. 20°. 
Hab. Guatemata (Mus. Paris 1), 
I have not seen an example of this species, which apparently bears a superficial 
resemblance to the male of P. centrolineata and is not much larger than that insect ; 
the head, however, is much blunted at the apex and less deeply furrowed, and the eyes 
are somewhat less prominent. 
5. Phera nigriceps. 
Tettigonia nigriceps, Sign. Ann. Soc. Ent. Fr. 1855, p. 508, t. 21. fig. 1’. 
Hab. Guatemata (coll. Signoret }, in Mus. Vind. Ces.). 
I have not seen a specimen of this insect, which, according to Signoret, is rather a 
small species (11 millim. in length) with clear hyaline tegmina, yellow thorax, and 
long black head, which is pointed and deeply sulcate. 
6. Phera insolita. (Tab. XIV. figg. 2, 2a.) 
Proconia insolita, Walk. List of Homopt. Ins., Suppl. p. 227 (1858) *. 
Hab. Muxico (Sallé, in Mus. Brit.1; Boucard, in Mus. Holm.), Ventanas in 
Durango (Forrer), Cuernavaca in Morelos (H. H. Smith; Bilimek, in Mus. Vind. Cees), 
Tepetlapa, Omilteme, and Dos Arroyos in Guerrero (H. H. Smith). 
I have had specimens of this species sent to me among undetermined material 
belonging to both the Vienna and Stockholm Museums. The general colour of the 
tegmina, when unfolded, is a tawny-reddish, with broad hyaline apex; the colour, 
however, appears to be to a certain extent variable, and the specimen from Dos 
Arroyos seems to be almost a black variety of the species. 
We figure an example from Cuernavaca. 
7. Phera atrata, sp.n. (Tab. XIV. fig. 3.) 
Quoad formam et staturam P. obtusifronti affinis, nigra, nitidior; capite sat brevi, vertice obtuse producto fere 
eequilaterali, profunde sulcato; pronoto sat fortiter punctato, vix rugoso; scutello magno, ad medium 
punctato; tegminibus ad basim remotius punctatis, apicem versus levibus; pectore et abdomine ad 
medium subtus infuscatis vel nigris; metopidio, lateribus corporis subtus et pedibus testaceis, tibiis 
anticis et tarsis superne nigris. 
Black, somewhat shining, with the head rather short and broad, and the vertex obtusely produced in an 
equilateral triangle and deeply sulcate; pronotum rather strongly punctured, with the two impressions 
in front deep and pronounced ; scutellum large, punctured in the centre, the basal angles broadly smooth ; 
tegmina remotely punctured at the base, smooth towards the apex; central portion of the underside of 
the body dark, the sides, the metopidium, and the legs being testaceous; upperside of the anterior 
tibiee and tarsi dark. 
Long. 11 millim. ; lat. ad hum. 3 millim. 
Hab. Guatemata, San Gerénimo (Champion).
