84 HEMIPTERA-HOMOPTERA. 
6. Bothriocera albidipennis, sp.n. (Tab. IX. figg. 17, 17a, 2; 18, 3, 
tegminal segments of abdomen, from beneath.) 
Subparallela, postice vix ampliata; vertice fronteque flavescentibus, hac utrinque nigro-maculata; pronoto 
-perangustissimo, flavescenti, sub oculis nigro; scutello nigro, pernitido, leviter carinato; tegminibus 
longis, flavescenti-albidis, nitidis; alis lacteo-fumosis; abdomine supra subtusque nigro ; pedibus dilute 
testaceis. 
Subparallel, not much widened behind; vertex and forehead yellowish, the latter with a large spot on each 
side of the central carina and the margins of the ear-like processes black; pronotum yellowish, dark 
beneath the eyes; scutellum large, black, very shining, with three distinct carine, and with traces of 
two others on each side of the central one; tegmina long, shining, whitish-yellow, slightly fuscous at the 
sides towards the apex, folded one over the other at rest so as to conceal more than half the suture; 
abdomen black ; front-parts of the underside of the body and the legs whitish-testaceous. 
Male with the genital segment of the abdomen produced triangularly beneath and angled at the sides, and the 
styles short and thick. 
Long. cum tegm. 53-6 millim. 
Hab. Mexico, Omilteme in Guerrero (4. H. Smith). 
This and the next species have at first sight the appearance of a small Plectoderes, 
rather than of a Bothriocera; they have the vertex, frons, and clypeus, however, 
shaped just as in the latter genus, and the extra ocellus at the apex of the frons is 
very distinct. It is possible that these two insects may hereafter be treated as 
generically distinct. The single male specimen received is smaller than the other two, 
which are females. 
7. Bothriocera nigra, sp.n. (Tab. IX. figg. 19, 19a.) 
Precedenti quoad formam structuramque valde affinis, sed minor et angustior; capite rufo-flavo; pronoto 
angustissimo, flavescenti, sub oculis fuscato ; scutello tegminibusque nigris, nitidis, his parallelis, postice 
haud ampliatis, humeris flavescenti-rufis, ad apicem extremum subpellucidis; abdomine nigro, corpore 
subtus antice colore variante ; pedibus flavis ad partem infuscatis. 
Closely allied to the preceding, but smaller and narrower, entirely of a dark or black colour, with the exception 
of the head, pronotum, shoulders, and legs, which are reddish-yellow ; the very narrow pronotum has 
dark spots under the eyes; and the legs are in part infuscate ; the scutellum is large, tricarinate; and the 
tegmina are very shiny, not narrowed behind, and folded one over the other as in B. albidipennis. 
Male with the genital segment deeply emarginate, and the styles long, slender, much thickened at their apex. 
Long. cum tegm. 44-5 millim.; lat. ad hum, 2 millim. 
Hab. Mexico, Cuernavaca in Morelos (H. H. Smith & Baill). 
The single example in our collection is much more shining than four specimens 
which I have received from Mr. Ball from the same locality; the latter, too, are 
sprinkled with a greyish secretion, such as is found in certain of the Flatide. 
BOTHRIOCERODES, gen. nov. 
Genus Bothriocere affine, sed lateribus frontis supra visis minus elevatis, et fronte ipsé pone medium dilatata 
distinguendus ; vertice brevi, ocello frontali conspicuo; pronoto brevissimo; scutello magno, tricarinato ; 
tegminibus amplis, subparallelis, vel apicem versus leviter ampliatis; tibiis posticis simplicibus. 
Closely allied to Bothriocera, but easily distinguished by the shape of the frons and clypeus, which in the last-
