regarded as a true Tettigonia. In some points it approaches the genus Ochrostacta, 
Stal, but in others it does not answer to his description. 
1. Pherodes flammeicolor, sp.n. (Tab. XIV. fig. 10.) 
Angusta, parallela, lete flammea, marginibus ad medium tegminum peranguste nigris, vertice elongato 
triangulari, margine extremo et quibusdam maculis parvis nigris, postice subexcavato, antice leviter 
sensim assurgenti ; oculis fuscis, elongatis, modice prominulis ; pronoto leviter sculpturato, ante scutellum 
nonnihil sinuato; scutello magno; tegminibus nitidis, levibus, suturé peranguste nigricanti; abdomine 
supra ad latera fusco-notato; capite subtus et pedibus dilutioribus. 
Of a bright orange-colour, with part of the underside and the legs light testaceous, the upperside of the 
abdomen partly brownish at the sides, and the extreme margins ef the head, pronotum, and basal half 
of the tegmina, as well as the suture very narrowly, black; there are also a few black markings on the 
vertex, which is shallowly excavate behind the middle and very slightly and gradually reflexed in front ; 
head long, triangular; eyes rather long and not very prominent; pronotum finely sculptured, with two 
small dark markings at the base; scutellum large, with two very small dark markings at the base 
meeting those on the pronotum ; tegmina small and shining, hyaline. 
Long. 11 millim.; lat. ad hum. 23 millim.

CYRTODISCA. 
Cyriodisca, Stal, Kongl. Svensk. Vet.-Ak. Handl. Band viii. no. 1 (Hemipt. Fabr. 11.), p. 60, nota 
(1869). 
This genus was formed by Stal to include the Tettigonia major of Signoret ; it is 
distinguished from Phera by having the head distinctly broader than long and plainly 
shorter than the pronotum, and from Oncometopia by the subtriangular and more 
strongly impressed head, which usually has the longitudinal line at the base deeply 
marked; the two veins of the clavus are usually separate, but this character, which 
Stal mentions as one of the characteristics of the genus, is variable, and in a specimen 
before me the two veins cross and form an irregular X; the tegminaare reticulate behind 
the middle, the reticulations being bounded by rather fine but distinct venation.
