TETTIGONIA, . 243 
colore dilutiori et obscuriori plus minusve distincte variegatis, apice late hyalino ; alis fumosis; abdomine 
flavo; corpore subtus testaceo; pedibus piceis. 
Allied to 7’. punctulata, but, as a rule, larger, with the front parts more confluently marked and lighter, and 
the head broader and shorter; scutellum variegated in front, the apex plain testaceous ; tegmina red, 
mottled obscurely with lighter and darker colour, and without any trace of a linear arrangement of the 
colour such as is always present in 7’. punctulata, the apex broadly hyaline; wings smoky; abdomen 
yellow ; underside testaceous ; legs pitchy or pitchy-testaceous. 
Long. 11-12 millim.; lat. ad hum. vix 3 millim. 
Hab. Mexico (Sallé; Mus. Vind. Ces.; Mus. Holm.), Cuernavaca in Morelos, 
Xucumanatlan, Chilpancingo, Amula, and Omilteme in Guerrero, Atoyac in Vera 
Cruz (H. H. Smith), Orizaba (Bilimek, in Mus. Vind. Ces.). 
I have found specimens of this species among the unnamed material sent me from 
the Stockholm and Vienna Museums; it is very distinct, but has apparently been 
overlooked. 
The examples from Cuernavaca, Chilpancingc, and Atoyac have the markings much 
coarser and more confluent, but they do not appear to be structurally different from 
the others. 
We figure a specimen from Xucumanatlan. 
22. Tettigonia preterita, sp.n. (Tab. XV. fig. 21.) 
Nigra vel fusca, testaceo plus minusve notata; capite producto, triangulari, oculis vix prominulis ; pronoto 
convexo, duabus maculis distinctis et aliis notis testaceis; scutello nigro, testaceo-variegato, postice 
testaceo; tegminibus rubris, apice hyalino, fere concoloribus sine lineis vel notis obscurioribus ; abdomine 
supra rufescenti; corpore subtus plerumque nigro, testaceo-variegato; pedibus testaceis, ad partem 
nigricantibus. 
Black or fuscous, with testaceous markings, and two conspicuous similarly coloured spots, one on each side of 
the central line of the pronotum ; tegmina crimson, without distinct lines or darker markings, hyaline at 
the apex ; abdomen red or brownish above, reddish in the middle beneath, the rest of the underside dark, 
with testaceous markings ; legs testaceous, partly black or pitchy. 
Long, 9 millim.; lat. ad hum. 2 millim. 
Hab. Mexico, Xucumanatlan and Omilteme in Guerrero 7000 to 8000 feet 
(H. H. Smith). 
After working through a large number of examples of the species of Tettigonia with 
red tegmina, which form the most obscure and difficult group of the genus, I came at 
last to three specimens which could not be referred to any of the others: two of these 
I have here described under the name TZ. preterita. ‘They differ inter se in the 
markings of the head and pronotum, but appear to be structurally alike. The present 
species is allied to 7’. punctulata, from which it differs in having the tegmina wider at 
the apex and differently coloured, as well as in the quite different markings of the fore 
parts; from 7’. germana they may be distinguished by the shorter elytra and the longer 
and more triangular head. 
The specimen from Xucumanatlan is figured.
