3. Largus affinis, n. sp. (Tab. XX. fig. 12.) 
Head shining black and pilose, the base with a narrow reddish transverse line; antennse black, pilose, base of 
first joint reddish, third joint very short, second a little shorter than fourth, basal joint longest. Pronotum . 
reddish, the lateral margins and anterior lobe reddish ; anterior lobe with the frontal margin ochraceous, 
preceded by black punctures, with two large irregularly rounded black spots on its disk, and its posterior 
margin irregularly punctured with black; posterior lobe thickly and coarsely punctured with black, 
excepting posterior margin, which is broadly ochraceous and impunctate. Scutellum reddish ochraceous, 
covered with coarse black punctures, which are confluent at base, and with a faint, central, pale, longi- 
tudinal line. Corium reddish ochraceous, coarsely covered with black punctures, which, becoming con- 
fluent on disk, form an irregular transverse spot; the apical margin black, and the costal margin broadly 
ochraceous and impunctate. Membrane pale ochraceous and unicolorous. Body beneath piceous; anten- 
niferous tubercles, base of rostrum, buccule, acetabula, bases of coxe, anterior margin of prosternum, 
posterior margin of pro-, meso-, and metasternum, and lateral margins of sternum and abdomen more or 
less ochraceous. Abdominal segments with their posterior margins greyish tomentose. Legs black, 
pilose ; anterior femora armed beneath with two strong subapical spines, one long and prominent, the 
. other, near apex, subprominent. Rostrum black, reaching intermediate coxe. 
Long. 17 millim. 
Hab. Guatemata, San Gerénimo (Champion). 
We have received but one example of this species from Mr. Champion ; it is allied 
to L. subligatus, but differs by the less levigate structure of the anterior pronotal lobe, 
the different colour of the corium and base of antenne, and also by the various ochra- 
ceous sternal spots. 
Base of metasternum sometimes pale coloured ; abdomen concolorous. 
4, Largus convivus, (Tab. XX. figg. 13, 14.) 
Largus convivus, Stal, Ofv. Vet.-Ak. Férh. 1861, p. 196. 1°; En, Hem. i. p. 94. 10%. 
Largus obtusus, Walk. Cat. Het. vi. p. 33. 23°. 
Hab. Norra America, California (coll. Dist.); Mexico’, Orizaba*, Ciudad and 
Ventanas (Forrer), Jalapa (Hoge), Oaxaca (Mus. Berol.); GUATEMALA, Quezaltenango, 
El Reposo (Champion). 
In his ‘Enum. Hem.” Stal placed his Z. convivus in the section of species which have 
the metasternum generally concolorous ; but in a typical specimen, identified by Stal and 
kindly submitted to me for inspection by Dr. Aurivillius, the posterior margin of the 
metasternum is distinctly reddish. It is a most variable species: even in the Mexican 
specimens now before me the colour of the corium varies from black to red, as in the 
specimens figured; the base of the metasternum is reddish in some specimens, con- 
colorous in others; whilst the red coxal spots are almost entirely absent, or not only 
present, but even the bases of the femora are also red, thus approaching L. succinctus, 
a species which, when specimens have been collected from New Mexico, I shall not be 
surprised to find claiming Z. convivus as a varietal form.
