RUDIA. : 105 
3. Rudia bicincta. (Tab. XI. fige. 12, 12 a.) 
Achilius bicinctus, Spinola, Ann. Soc, Ent. Fr. 1889, p. 321, t. 16. figg. 1, 1 a-c’. 
Rudia dicincta, Stal, Berl. ent. Zeitschr. 1866, p. 3927. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith); Guatemata, Paraiso, Cerro Zunil, 
San Isidro, Zapote, San Gerdnimo (Champion).—Souta America), 
Spinola’s description of this insect is very meagre and based on a single female 
specimen, and we therefore append a full one. His figure corresponds closely with 
our specimens, with the exception of the vertex, which is less produced ; the separate 
figure of the frons, moreover, is shorter and broader. We have not seen a type of 
R. bicincta, and it is possible that our insect may be distinct, but the species is 
variable, and it is possible that the shortness of the vertex in Spinola’s figure may 
be due to an error on the part of the draughtsman. 
Precedentibus (quoad formam typicam) brevior et minus parallela, tegminibus pone magis dilatatis ; vertice 
ante oculos distincte producto, antice et ad latera recta nigro carinato-marginato, carind media distincta 
rufa; fronte clypeoque vitté’ magna centrali et lateribus rufis; pronoto rufo-tricarinato; scutello sat 
brevi, carinis tribus magnis rufis; tegminibus pellucidis, vittis singulis vel duabus transversis variantibus, 
interdum fere deficientibus, venis distinctis apicem versus setis rectis instructis; corpore variante; 
pedibus testaceis variantibus. 
Shorter and less parallel than the typical form of the preceding species ; colour in life apparently green, with 
the margins and the centre of the vertex, the carine of the front parts, and more or less of the body and 
legs red (dried specimens are mostly testaceous, with more or less distinct traces of the red and green 
colour); vertex plainly produced before the prominent eyes, carinate; pronotum in the centre almost as 
long as the scutellum, which it overlaps (and so causes it to appear to vary in length); tegmina trans- 
parent, with strong dark veins, which are set with upright dark sete on their apical half, and with one 
or two transverse, more or less irregular, dark bands, one at or behind the shoulders, usually absent, 
and another at the middle, usually distinct ; legs set with bristles at the sides, the posterior tibie with 
three very distinct spines. 
Male with the last segment of the abdomen emarginate, and the segment of the pygofer considerably produced 
and narrow. 
Long. cum tegm. 7 millim.; lat. ad hum. 3 millim. 
4. Rudia verticalis, sp.n. (Tab. XI. figg. 13, 13.) 
Precedenti valde affinis, sed major, vertice multo longiori, margine apicali fere rotundato, nigro-marginato et 
carinato; scutello pronoto fere sesqui longiori, carinis lateralibus fuscis; tegminibus haud vittatis, sed 
venis transversis bene notatis ; pedibus testaceis. 
Allied to the preceding, but larger, and at once distinguished by the shape of the vertex, which is produced in 
the form of a duck’s bill before the eyes, and has the apex and the sides in front more or less rounded ; 
the keels of the front parts are for the most part dark; tegmina without bands, but with the transverse 
veins strongly marked with dark colour ; legs testaceous, more or less pitchy. 
Long. cum tegm. 8 millim.; lat. ad hum. 3 millim. 
Hab. Guaremata, Panzos and Teleman in Vera Paz (Champion). 
Three female specimens. There is a very small specimen from Bugaba in our 
collection apparently belonging to the same species; it measures 5 mm. in length, and 
is apparently immature.
