Allied to M. vi'cina, 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 tlie 

 pronotiim slightly but distinctly sinuated. 



The genus Memmia was hitherto known only from Mada- 

 gascar. 



Mackopelta, gen. no v. 



Caput subhexagonum, parte anteoculari apicem versus angustata, 

 jugis tjlo pauUo 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 subasqualibus, anteunis quadri- 

 articulatis, articulo primo apicem capitis parum superante, secundo 

 ceteris longiore. Proaotum lateribus ante medium serratum, 

 angulis posticis acute lobulato-prominulis. Scutellum perlongum, 

 abdomine paullo brevius, corio longius, lateribus ante medium 

 sinuatis, frenis medium sciitelli baud attingentibus. Prosternura 

 apice medio profundius arcuato-sinuatum ; mesosternum medio 

 lougitudiualiter impressum, in fundo impressionis carinatum ; 

 orificia auriculata. Abdomen subtus sulco levi longitudinali 

 instructum. Femora subtus spinulosa. 



This genus is at once distinguished from Memmia^ Stal, by 

 the scutellum, which is longer than the corium and sinuated 

 before the middle (as in Brachymenum, May r) , and by the f rena, 

 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. There are also the 

 following differences of minor importance : — The first an- 

 tennal joint scarcely passes the apex of the head, the second
