124 HEMIPTERA-HOMOPTERA. 
5. Thionia sordida, sp.n. (Tab. XII. figg. 19, 19 a.) 
Pracedenti affinis, sordide testacea, vertice brevi, subquadrato, excavato, fronte quam in. 7’ scutellata latiori, 
carinis magis distinctis ; scutello precipue ad basim nigro-notato, postice maculis duabus parvis nigris ; 
tegminibus pone humeros late angulatis, sordide testaceis, maculis fuscis irregularibus, reticulatis ; 
corpore pedibusque testaceis, nigro plus minusve notatis. 
Very closely allied to the preceding, but distinguished by the shorter and broader forehead, which has the 
side-keels stronger and forming a shorter oval, and the more reticulate tegmina ; the general appearance 
is duller, the tegmina being of a sordid testaceous colour, with irregular dark markings; the male- 
characters appear to be much the same, except that the callosities of the abdominal segments are not so 
strongly marked. 
Long. cum tegm. 63-7 millim. ; lat. ad hum. 3 millim. 
Hab. Mzxico, Amula in Guerrero 6000 feet (H. H. Smith). 
I had at first included this species under the preceding, but it appears to be 
distinct. 
6. Thionia humilis, sp.n. (Tab. XII. figg. 20, 20 a.) 
Parva, brevis, sat lata, testacea, fusco irregulariter sat dense notata ; capite brevi, vertice leviter transverso, 
fronte lateribus ad apicem rotundatis, verticem versus sensim angustatis; pronoto sat magno, maculis 
minutis nigris, ad medium biimpresso, carinato; scutello pronoto vix longiori, nigro notato, carinato ; 
tegminibus sat latis, marginibus ante medium perobtuse angulatis, apicibus oblique subrotundatis ; 
pedibus testaceis, ad partem fuscatis. 
Femina segmento ultimo ventrali simplici. 
A small, short, rather broad species, of a dirty-testaceous colour, with irregular darker markings ; head short, 
vertex a little broader than long, forehead with the sides rounded towards the apex, gradually narrowed 
to the base; pronotum with minute black spots, and with a central keel and a depression on each side, 
as long as the scutellum; scutellum with central keel; tegmina with rather strong, light testaceous 
reticulation towards the apex, and the sides very obtusely angled before the middle; legs testaceous, in 
part more or less fuscous. 
In the female the last ventral segment of the abdomen is simple. 
Long. cum tegm. 53 millim.; lat. ad hum. 3 millim. 
Hab, Mexico, Amula in Guerrero (H. H. Smith). 
This species is allied to 7’. sordida, but is shorter and broader, with the forehead 
wider and the tegmina shorter, more ovate, if viewed from above, and more distinctly 
and strongly reticulate. 
7. Thionia naso, sp.n. (Tab. XII. figg. 21, 21 a.) 
Castanea, testaceo perobscure variegata, nitida ; vertice longo, latitudine distincte longiori, ante oculos fortiter 
producto, acuto, fronte longé, subparallela, medio carinata, clypeo ad medium paullo elevato; pronoto sat 
longo, antice angulato ; scutello pronoto sesqui longiore; tegminibus venis crassis, regularibus, venis 
transversis minoribus ; pedibus testaceis, spinis duabus tibiarum posticarum sat parvis. 
Castaneous, indistinctly variegated with testaceous, shining ; vertex long, distinctly longer than broad, strongly 
produced before the eyes and acuminate, margined at the sides, and with a distinct longitudinal impression 
at the base; forehead long, subparallel, with a central carina; pronotum comparatively long; seutellum 
about one and a half times as long as the pronotum ; tegmina with the veins regular and strongly marked, 
and with somewhat less distinct transverse veins; legs testaceous.
