ZACORUS.—ZOSIPPUS. 24) 
oblique linear incisions, the two posterior almost united by two rounded fovee, the posterior lobe some- 
what thickly clothed with ochraceous pilosity. Scutellum with the basal area black, remainder brownish, 
clothed with long ochraceous hairs, and with the central spine pale ochraceous, suberect, and very slightly 
directed forwardly. Corium dark chocolate-brown, palely pilose; extreme outer basal margin ochraceous, 
with a central transverse greyish spot followed by a patch of richer dark chocolate-brown; the apex 
broadly black and opaque, with a small greyish spot near inner base of membrane. Cuneus greyish 
white, more or less shaded with pale fuscous. Membrane very pale fuscous, its outer margin paler. 
Legs very dark chocolate-brown, clothed with long greyish sete or hairs; extreme apices of femora and | 
base of tibie pale luteous; apical halves of tibie more or less ochraceous. Body beneath (imperfectly 
examined owing to the specimen being carded) dark shining fuscous; marginal and basal fascie to head, 
acetabula, and two marginal spots to abdomen (one near centre and one about apex) ochraceous. Rostrum 
brownish ochraceous, with the apex pitchy. 
Long. 10 millim. 
Hab. Guatemaua, Senahu (Champion). 
One specimen only of this extremely interesting and, in many respects, remarkable 
insect has been obtained. 
2. Zacorus curvicornis, n. sp. 
Closely allied to the preceding species in markings and coloration, but differing by its smaller size, the scutellal 
spine strongly curved backwards, the anterior lobe of the pronotum quite distinct, having an interior 
transverse globose ridge with a distinct obtuse spine near each anterior angle, and wanting the incised 
markings of the preceding species. The antenne are also much paler in hue, the anterior portion of the 
head more or less brownish ochraceous ; the legs pale ochraceous, femora more or less irregularly suffused 
with brownish, and tibia (excluding base and apical half) also brownish. 
Long. 6-7 millim. 
Hab. Panama, Bugaba (Champion). 
ZOSIPPUS, gen. nov. 
Allied to Zacorus, bat differing in the pronotum, which is constricted nearer the anterior margin, and has 
both lobes semiglobose; its posterior margin is also truncate, and the anterior margin slightly convex. 
The head is somewhat vertically deflected beyond the eyes; antenne with the first joint about the length 
of the head, second joint about or a little more than twice the length of the first, its apical portion only 
moderately incrassated (remaining joints mutilated). Scutellum much as in the preceding genus, but 
with a broad, central, conical obtuse spine. Other characters generally as in Zacorus. 
1. Zosippus inhonestus, n. sp. (Tab. XXIV. fig. 6.) 
Subelongate, finely and palely pilose. Head and pronotum black, the posterior margin of the last narrowly 
and obscurely ochraceous. Head with the antennal bases and lateral margins in front of eyes ochraceous ; 
antenne fuscous, basal portion of first joint distinctly luteous (third and fourth joints wanting). Scutellum 
dark shining fuscous. Corium fuscous, with a central transverse greyish spot followed by a very dark 
fuscous patch and a large apical ochraceous spot; a small rounded ochraceous spot- at inner base of 
membrane, and the inner claval area at margins of scutellum very dark fuscous. Cuneus fuscous, 
thickly covered with ochraceous pile. Membrane obscure fuscous. Legs very dark castaneous, clothed 
with long pale sete or hairs. Body beneath dark fuscous, the cox ochraceous (¢mperfecily examined 
owing to the specimen being carded). 
Long. 5 millim.
