is somewhat broader in form ; but it appears to be too closely allied to be described as 
a distinct species, at any rate upon a single example. 
11. Aulacizes thunbergi. (Tab. XIII. fig. 20.) 
Aulacizes thunbergii, Stal, Stett. ent. Zeit. xxv. p. 79 (1864) ’. 
Hab. Mexico, Vera Cruz (Mus. Holm.+), Atoyac in Vera Cruz (Schumann), Jalapa 
(Bilimek, in Mus. Vind. Ces.), Chiapas (M. Trujillo), Valladolid in Yucatan (Gaumer) ; 
GuateMaLa, Lanquin, San Juan, Chiacam, Balheu, and San Gerénimo in Vera Paz 
(Champion); Nicaragua, Chontales (Janson). 
This species varies considerably in coloration. It is a somewhat elongate insect, with 
the head considerably produced, of a dark colour, with a number of large variable and 
more or less confluent spots, which are either bright crimson, scarlet, or yellow; these 
are sometimes much reduced, but often form the greater part of the ground-colour. 
It would be quite impossible to recognize the example belonging to the Vienna 
Museum, which I have before me, and which was presented by Stal himself, by means 
of his description above referred to}. 
An example from Chiacam is figured. 
12. Aulacizes amblardi. 
Tettigonia amblardii, Sign. Ann. Soc. Ent. Fr. 1855, p. 53, t. 6. fig. 7*. 
Hab. Mexico (coll. Signoret, in Mus. Vind. Ces.).—Boutvia (Mus. Vind. Ces.1). 
13. Aulacizes panamensis, sp. n. (Tab. XIII. fig. 21.) 
Elongata, parallela, capite pronotoque griseo-testaceis vel flavo-testaceis, illo vertice sat producto, maculis 
quatuor parvis nigris, ad medium sulcato, hoc leviter rugoso, maculis quatuor ad apicem lineatim 
dispositis, et margine basali, nigris; scutello fusco; tegminibus levibus, testaceis vel brunneis vel griseo- - 
brunneis, subhyalinis, perobscure vittatis; corpore supra fusco vel fusco-rufescenti, subtus testaceo ; 
pedibus dilute testaceis. 
Elongate, parallel, with the head and pronotum greyish or yellowish-testaceous ; vertex with two small black 
markings at the apex and two at the base, the former occasionally absent, and with a deep short furrow 
in the centre; pronotum with the base dark and with four constant small black spots arranged longi- 
tudinally just before the apical border, finely rugose longitudinally; scutellum large, shining, fuscous ; 
tegmina smooth, semitransparent, somewhat variable in colour, with more or less distinct lines of darker 
bands, which are often scarcely traceable, the apex and the suture broadly before the apex more or less 
conspicuously darker than the ground-colour ; upperside of the abdomen more or less dusky, the underside 
and legs light testaceous. 
Long. 14-15 millim.; lat. ad hum. 3-33 millim. 
Hab. Panama, Bugaba, Caldera, and Volcan de Chiriqui (Champion). 
This species is rather closely allied to A. amblardi, bat may easily be known by the 
longer and narrower head, and by the shape of the metopidium, which is convex and 
rounded for some distance, and then terminates in a very blunt angle. It might,
