22. Anasa denticulata. (Tab. XIV. fig. 11.) 
Anasa denticulata, Stal, En. Hem. i. p. 196. 27°. 
Hab. Mexico ! (coll. Dist.). 
23. Anasa tenebricosa, n. sp. (Tab. XIV. fig. 12.) 
Dark fuscous. Antenne with the three basal joints obscure testaceous, spotted with fuscous; fourth joint 
fuscous, annulated near apex with ochraceous; first and fourth joints much incrassated, second and third 
subequal in length. Pronotum distinctly and somewhat coarsely punctate, with the lateral angles sub- 
prominent, ampliated, and rounded; lateral margins ampliated and reflexed, obscurely dentate anteriorly. 
Membrane dark cupreous. Connexivum black, with a segmental row of luteous spots. Underside of body 
concolorous, head and sternum paler and coarsely punctate ; femora spotted with black; tibize ochraceous, 
obscurely spotted with fuscous ; abdomen with a marginal row of ochraceous spots. 
Long. 10 millim. 
Hab. Costa Rica, Irazu (Rogers). 
Allied to A. denticulata, Stal, but differs by the less denticulated margins of the 
pronotum, the second and third joints of the antenne being subequal in length, its 
darker colour, &c. 
ZICCA. 
Zicca, Amyot & Serville, Hist. des Hém. p. 240 (1843) ; Stal, Ofv. Vet.-Ak. Férh. 1867, p. 547. 
This Neotropical genus is represented in Central America by three species. Zicca 
has the posterior femora somewhat incrassated and spined beneath. The basal joint of 
the antenne is longer than the second joint; and the lateral angles of the pronotum are 
acutely produced. 
1. Zicca commaculata, n. sp. (Tab. XIV. fig. 19.) 
Luteous, distinctly punctate. Antenne, margins of ocelli, a transverse spot at base of head between ocelli and 
eyes, pronotum with the lateral margins, a central spot near anterior margin, and posterior half from 
between lateral spines to base, scutellum and corium fuscous. Membrane black. Underside of body and 
legs luteous; sternum with six black spots on each side, two on prosternum (outer one on margin some- 
what obsolete), two on mesosternum, and two on metasternum ; abdomen with four longitudinal rows of 
black spots on disk and a marginal row of the same colour; femora luteous, coarsely spotted and annulated 
with black; tibie fuscous, distinctly annulated near middle, and more obscurely spotted near base with 
luteous. Abdomen above testaceous, with a submarginal row of black spots above the position of stigmata, 
and connexivum with a row of subquadrate black spots occupying apical halves of segmental margins. 
Antenne with the basal joint longest, second and third joints subequal, fourth shortest and incrassated. 
Pronotum with the lateral margins faintly and obscurely crenulated ; lateral angles produced into long 
acute black spines; posterior lateral margins behind spines distinctly spinous, from which to posterior 
angles they are deeply sinuate; posterior angles distinct and subacute; the posterior and fuscous portion 
is waved anteriorly, where it is much darker. Apex of scutellum narrowly luteous. 
Long. 9 millim., lat. pronot. ang. 4 millim. 
Hab. GuateMaLa, Cahabon (Champion). 
This species belongs to the section of the genus in which the connexivum is not 
unicolorous, but maculated. It is at once separated from Z. annulata, Burm., and
