articulo tertio secundo distincte longiore, antennis subtiliter 
puberulis, nigris, articulo secundo primo vix triplo longiore, tertio 
secundo circiter sexta parte breviore (art. quartus deest). Pro- 
notum utrinque prope latera profundius impressum, marginibus 
lateralibus anticis levissime sinuatis, ante medium crenatis, 
angulis lateralibus obtusis, subrotundatis, parum prominulis, 
angulis posticis obtuse rotundatis. Scutellum ad angulos basales 
fovea impressa preeditum. Corium basin segmenti sexti connexivi 
attingens ; membrana subfusco-hyalina, venis obscurioribus, 
Abdomen hemelytris nonnihil brevius, angulis posticis segmen- 
torum levissime prominulis. Pedes nigri, vitta supera femorum, 
plus quam dimidia parte basali femorum posteriorum carinisque 
superis lateralibus tibiarum a basi ultra medium testaceis.

Allied to M. vicina, Sign., but the colour-markings are 
different, the third antennal joint is much longer, the lateral 
lobes of the head are shorter, and the lateral margins of the 
pronotum slightly but distinctly sinuated. 
The genus Memmia was hitherto known only from Mada- 
gascar. 
MACROPELTA, gen. nov. 
Caput subhexagonum, parte anteoculari apicem versus angustata, 
jugis tylo paullo longioribus, apice distautibus, oculis valde 
exsertis, breviter stylatis, ocellis pone lineam inter basin oculorum 
fictam positis, rostro coxas posticas subattingente, articulis 
secundo et tertio longitudine subequalibus, antennis quadri- 
articulatis, articulo primo apicem capitis parum superante, secundo 
ceteris longiore. Pronotum lateribus ante medium serratum, 
angulis posticis acute lobulato-prominulis. Scutellum perlongum, 
abdomine paullo brevius, corio longius, lateribus ante medium 
sinuatis, frenis medium scutelli haud attingentibus. Prosternum 
apice medio profundius arcuato-sinuatum; mesosternum medio 
longitudinaliter impressum, in fundo impressionis carinatum ; 
orificia auriculata. Abdomen subtus suleo levi longitudinali 
instructum. Femora subtus spinulosa. 
This genus is at once distinguished from J/emmia, Stal, by 
the scutellum, which is longer than the corium and sinuated 
before the middle (asin Br achymenum, Mayr), and by the frena, 
which do not reach the middle of the scutellum. In Memmia 
the scutellum is considerably shorter than the corium and 
sinuated much behind the middle, and the frena reach much 
beyond the middle of the scutellum. ‘here are also the 
following differences of minor importance :—The first an- 
tennal joint scarcely passes the apex of the head, the second
