TETTIGONIA. 289 
A very small, white species, variegated and lined with fuscous ; head rather large, produced and rounded, eyes 
not prominent ; forehead very thickly lined transversely, the lines being usually continued for a short 
distance on each side of the front of the vertex ; vertex with a central space light, bounded by a narrow 
black line on each side, and with a narrow black line in the centre ; pronotum scarcely longer than the 
head, almost parallel-sided, with two broad longitudinal rufous-brown bands in the middle and two narrow 
dark fuscous bands outside; scutellum with one dark line; tegmina subvitreous, yet with very distinct 
and sharp fuscous lines ; abdomen black above; underside and legs whitish or whitish-yellow. 
Long. 4-5 millim.; lat. 1 millim. 
Hab. Mexico, Venta de Zopilote, Xucumanatlan, and Amula in Guerrero (H. H. 
Smith). 
A specimen from Xucumanatlan is figured. 
153. Tettigonia mollicella, sp. n. (‘Tab. XIX. tig. 24.) 
Precedenti affinis, sed major, capite breviori. oculis magis prominulis, vertice maculis tribus nigris transversim 
dispositis; pronoto vittis duabus rufo-brunneis transversis; scutello haud lineato; tegminibus dilutius 
lineatis, et abdomine flavo, facile distinguenda. 
Allied to 7’. mollicula, but on the average slightly larger, with a considerably shorter head and less prominent 
eyes ; on the vertex there are three small black spots arranged transversely, and the lines on the fore- 
head are much less marked and sometimes almost absent, and are not continued on the vertex; on the 
pronotum, which is shorter, are two rather broad transverse reddish-brown bands, the colour being usually 
faint ; scutellum without the distinct central dark line; tegmina less clearly lined; abdomen yellow or 
whitish-yellow. 
Long. 5-6 millim.; lat. 1 millim. 
Hab. Mexico, Orizaba (Ff. D. Godman & H. H. Smith), Atoyac in Vera Cruz 
(Schumann), Vera Cruz, Teapa (1. H. Smith). 
We figure a specimen from Vera Cruz. 
154. Tettigonia tenera, sp. n. 
Preecedenti affinis, sed capite paullo magis producto, vittis latis transversalibus brunneis verticis et pronoti, 
lineisque rarioribus tegminum facile distinguenda. 
Allied to 7’. mollicella, but with the head a little larger and more produced, without the black spot just before 
the vertex, and with a broad, brown, transverse band between the eyes; there is another broad brown 
band like this across the pronotum and two others in front of the pronotum and scutellum, as well as a 
narrower one towards the apex of the latter; two or three narrow brown lines extend across the upper 
part of the forehead; the tegmina are furnished with a few broader dark lines, especially towards 
the apex. 
Long. 6 millim.; lat. 1 millim. 
Hab. Mexico, Atoyac in Vera Cruz (Schumann). 
The two preceding species are each represented by four specimens in our collection, 
but there is only one example of 7. tenera; it is, however, so easily recognized by 
the banded appearance of the front parts of the body that I have thought it best to 
describe it.
