NEOCATTARUS.—RHYPAROCHROMUS. 215 
4. Neocattarus parvus, n.sp. (Tab. XX. fig. 1.) 
_ Head, pronotum, and scutellum piceous ; antennz with the first three joints ochraceous, apex of second and 
base of third joints castaneous, apical joint piceous ;. first and third and second and fourth joints subequal 
in length. Anterior margin of pronotum narrowly obscure ochraceous. Clavus castaneous, with a fuscous 
spot a little beyond centre. Corium ochraceous, with a few scattered dark punctures, apical and posterior 
portion of inner margin broadly piceous, with a whitish spot near inner angle ; two fuscous costal spots, 
one near base and the other (largest) about centre. Membrane fuscous, the margins pale hyaline. Body 
beneath fuscous, posterior angles of metasternum pale ochraceous. Coxe and anterior femora piceous, 
the last with their apices pale ochraceous; anterior tibie and tarsi and intermediate and posterior legs 
ochraceous, the last with the femora annulated with castaneous near apices, the bases of tibie also castaneous. 
Long. 3 millim. . 
Hab. Guatumata, Volcan de Atitlan (Champion). 
The small size, markings of corium, and relative length of the antennal joints 
sufficiently distinguish this species. 
5. Neocattarus gracilis, n. sp. (Tab. XX. fig. 2.) 
Head, anterior lobe of pronotum, and scutellum black ; posterior lobe of pronotum dull, dark, obscure castaneous, 
with the lateral angles narrowly ochraceous. Antenne with the first, second, and third joints ochraceous, 
the fourth fuscous with the base ochraceous ; the second joint subequal to or a little longer than fourth, third 
longer than first. Clavus fuscous, with a black spot on each side near apex. Corium ochraceous, with an 
oblique fuscous spot near base, a transverse fascia near inner angle, and a very broad apical margin dark 
castaneous, with a pale spot near inner angle, and a smaller and more obscure one a little below it near apical 
margin, and afuscous subclaval streak. Membrane pale hyaline, with greenish reflections, the base fuscous. 
Body beneath piceous ; posterior angle of metasternum ochraceous; four spots at base of mesosternum, 
one linear near each lateral margin, and two rounded on disk, two at base of metasternum, and a large 
transverse discal fascia occupying nearly the whole of second abdominal segment, and extending to disk of 
third segment, pale, silvery, pubescent. Legs ochraceous; anterior femora, excepting apices, apical halves 
of posterior femora, and the posterior tibia dark castaneous or piceous, apical halves of. intermediate femora 
pale castaneous. 
Head and anterior lobe of pronotum obscurely rugulose, posterior pronotal lobe distinctly punctate; scutellum 
with a few distinct coarse punctures; clavus and subclaval area longitudinally punctate; corium with a 
few scattered punctures. 
Long. 34 to 4 millim. 
Hab. Guatema.a, San Isidro, Pantaleon (Champion). 
RHYPAROCHROMUS. | 
Rhyparochromus, Curtis, Brit. Ent. xiii. p. 612 (1836) ; Stal, Ofv. Vet.-Ak. Férh. 29: 7, p. 52 
(1872). 
Megalonotus, Fieb. Eur. Hem. pp. 47 & 181 (1861). 
In this genus the anterior lobe of the pronotum is much longer than the posterior, 
and has the lateral margins strongly rounded, the second and third joints of the rostrum 
are subequal in length, and the anterior femora are incrassated and have a distinct 
subbasal spine. — 
This is a Palearctic genus, of which Pamera una, Say (identified as a Mega- 
lonotus by Mr. Uhler), is a North-American representative. pe
