PHERA. 223 
Several specimens. This species bears: much the same relation to P. aterrima that 
P. obtusifrons bears to P. luciola. 
8. Phera luciola, n. sp. (Tab. XIV. fig. 4.) 
Tettigonia luciola, Sign. Ann. Soc. Ent. Fr. 1855, p. 289, t. 12. fig. 18 '. 
Ciccus lucicola (sic), Walk. List of Homopt. Ins., Suppl. p. 243 *. 
Hab. Mexico? (coll. Signoret +, in Mus. Vind. Cas.). 
This species is allied to P. centrolineata, but may at once be known by its more 
elongate and narrower head. 
9. Phera tiarata. 
Phera tiarata, Stal, Stett. ent. Zeit. xxv. p. 79 (1864) '. 
Hab. Mexico, Vera Cruz (Mus. Holm. '). 
This insect is intermediate between P. luciola and P. centrolineata. It is probable 
that P. téarata is nothing more than a variety of the latter species, but as one example 
only has been seen Ido not feel justified in sinking the name as a synonym. Stal 
himself speaks of it as “P. centrolineate maxime affinis, capite nonnihil longiore, 
magis acuminato, presertim differt.” 
10. Phera centrolineata., (Tab. XIV. fig. 5.) 
Tettigonia centrolineata, Sign. Ann. Soc, Ent. Fr, 1855, p. 239, t. 12. fig. 19°. 
Ciccus centrolineatus, Walk. List of Homopt. Ins., Suppl. p. 243 (¢) ?. 
Ciccus nigrilux, Walk. loc. cit. p. 246 (9) °. 
Hab. Mexico !? (Sallé, in Mus. Brit.3 ; Mus. Vind. Ces.; Mus. Holm.; Mus. Roy. 
Belg.), Tepetlapa and Chilpancingo in Guerrero, Teapa in Tabasco (H. H. Smith), 
Jalapa (M. Trujillo), Orizaba (H. H. Smith & F. D. Godman), Atoyac in Vera Cruz 
(Schumann), Oaxaca (Mus. Brit.). 
The male is black, with a conspicuous white line on the vertex, whereas the female 
(Ciccus nigriluz, Walk.) has the centre of the pronotum broadly, and the scutellum, 
reddish or orange-red. I have examined a considerable number of specimens and find 
that the insect is invariably coloured as described when mature ; occasionally in the 
female the whole head, pronotum, and scutellum are of a reddish-orange colour. The 
single example from Orizaba is a male, and is very light-coloured, but, so far as I can 
judge, this is due to immaturity. 
A specimen from Chilpancingo is figured. 
11. Phera obtusifrons, sp. n. (Tab. XIV. fig. 6.) 
Pracedenti affinis, sed capite latiori, et breviori, et multo magis obtuse producto, facile distinguendus ; capite 
supra flavo-rufescenti, subtus, parte antica et lateribus exceptis, nigro; pronoto ad medium scutelloque
