258 HEMIPTERA-HETEROPTERA. 
80. Resthenia marginanda. (Tab. XXII. fig. 16.) 
. Miniatous; anterior and posterior margins of pronotum and lateral margins of corium narrowly luteous. 
Antenne black ; head either dull ochraceous, with the apex and base black, or blackish, with a luteous 
spot at inner margin of eyes; pronotum with a transverse fuscous fascia a little before anterior margin ; 
cuneus with its apex more or less broadly luteous; membrane pale fuscous. Body beneath dull ochra- 
ceous ;. lateral margins of prosternum, lateral margins of abdomen, oviposital sheath, and lateral margins 
and apex of anal appendage more or less miniatous; cox# and femora ochraceous, apices of posterior 
femora, tibice, tarsi, and rostrum fuscous. 
The tibiz are strongly but sparingly setose, the anterior margin of the pronotum is distinctly sinuated, and the 
basal portion of the lateral margins of the pronotum distinctly reflexed. 
Long. 8 millim. 
Hab. Mexico, Oaxaca (Deppe, Mus. Berol.). 
31. Resthenia parva, n.sp. (Tab. XXII. tig. 18.) 
Miniatous ; antenne, apex, a circular fascia on vertex and basal margin of head more or less dark fuscous ; 
membrane pale fuscous; acetabula, coxe, and legs brownish ochraceous; tibie, tarsi, and rostrum 
fuscous. ) 
Anterior margin of pronotum not sinuate; eyes somewhat large and prominent, and slightly directed back- 
ward ; tibie finely setose. 
Long. 53 millim. 
Hab. Mexico (Deppe, Mus. Berol.). 
32. Resthenia divisa. 
Capsus tetrastigma, H.-S. Wanz. Ins. ix. p. 166. 
Capsus divisus, H.-S. Wanz. Ins. ix. fig. 960. 
Resthenia divisa, Stal, Stett. ent. Zeit. xxiii. p. 817. 236 *. 
Hab. Mexico! (coll. Sign.). 
A specimen in Dr. Signoret’s collection, whick constitutes my only knowledge of this 
species, having both the rostrum and antenne mutilated, I am unable to sectionize its 
systematic position. The lateral margins of the pronotum are obtuse and not anteriorly 
reflexed. 
LOPIDEA. 
Lopidea, Uhler, Hayden’s Surv. Mont. p. 411 (1872). 
The shape of the pronotum—which is “ trapezoidal, about one half wider than long ; 
the lateral edges carinately elevated; the middle of the posterior margin sinuately 
deflexed ”—will alone separate this genus from Resthenia, to which it is closely allied. 
According to our present knowledge, the geographical range of Lopidea appears to 
be restricted to the southern portion of the Nearctic Region and the northern portion — 
of the Neotropical.
