2. Sephina geniculata, n. sp. (Tab. XIII. fig. 10.) 
Black ; pronotum with the anterior margin (narrowly), the lateral margins, apical portion of the posterior margin 
and a central longitudinal fascia, apical half of scutellum, and costal margins of corium, red; a rounded 
luteous spot on disk of corium, and a number of irregular spots of the same colour on membrane. Abdo- 
men. above with the apical half red, connexivam with a segmental row of luteous spots. Underside of 
body black, mottled with reddish; margins and lateral angles of prosternum red, a testaceous spot near 
base of each coxa, and a lateral abdominal row of testaceous spots situated near stigmata. Legs black, 
apices of femora and bases of tibiz luteous. 
Antenne with the first and second joints subequal in n length, third a little shorter than fourth, second and third 
joints strongly sulcated above. 
Long. 16 millim., lat. pronot. ang. 6 millim. 
Hab. Costa Rica, Cache (Rogers). 
This is a very distinct form of the genus, and is not readily to be confused with any 
other species. One specimen only was received from Mr. Rogers. 
3. Sephina rogersi, n. sp. (Tab. XIII. fig. 9.) 
Black, finely pilose ; a semicircular fascia on disk of pronotum, commencing on each side at base, a little before 
lateral angles, and extending subparallel to lateral margins and narrowing and obscurely meeting a little 
before anterior margin, and basal margins of corium red. Abdomen above red; connexivum testaceous, 
with a segmental row of black spots. Underside of body red; rostrum, legs, anterior margin and a 
transverse spot on disk of prosternum, anterior fourth of mesosternum, a large spot near posterior coxe, 
abdomen with a row of broad discal transverse segmental fascie, sometimes semidivided, anal appendage 
(wholly in g, base only in @ ), stigmata, and a marginal segmental row of quadrate spots black. 
Antenne pilose, second joint a little longer than first, third and fourth subequal; pronotum with a few scattered 
coarse punctures, the lateral margins very strongly pilose, lateral angles prominent and subacute; corium 
very finely and obscurely punctate, clavus more distinctly punctate. 
Long. ¢ 21 millim., 2 25 millim.; lat. pronot. ang. ¢ 7 millim., 2 9 millim. 
Hab. Costa Rica, Cache (Rogers). 
_ This species is allied to S. limbata, St&l, from which it differs by the more prominent 
lateral angles of the pronotum, the red fascia not extending thereto, and the spotted 
connexivum, &c.

Honpvras, river Sarstoon (Blancaneaux) ; GuaTEMALA, Panzos, Chacoj (Champion). 
I have examined Walker’s type in the British Museum, and find that it is not a 
varietal form of this species, as the name and description would imply, the red fascia to 
the pronotum being present, but obscure, owing to the specimen being somewhat 
discoloured. As far as my experience goes, the species is quite constant in character. 
The specimen figured is from Guatemala.
