——— 
PARISTEMIA. Westw. 
Genus novum e familia Cerambycidarum, generibus Lophonocero et Pteracanthe Mewm.* 
affine. Caput parvum facie obliqua. Oculi valde emarginati. Labrum transversum 
ciliatum. Mandibule parve. Maxillze lobo apicali dense at breviter penicillato. Labium ad 
apicem emarginatum. Antenne breves (in femina vix ad medium elytrorum extensa), 
crass, articulis 1 et 3 longitudine subequalibus, reliquis parum brevioribus. Prothorax 
capite multo latior lateribus utrinque oblique porrectis vel in spinam latam productis, 
angulis posticis valde emarginatis 3 disco in medio elevato-carinato. Elytra ad basin vix 
prothorace latiora, sensim rotundato-dilatata, apicibus simplicibus, disco longitudinaliter 
costata. Pedes breves subequales. Species Africe tropicalis incole. 
Species I.—Paristemia Pratyptrra. (Plate 64, fig. 1). 
P. nigra sericea prothorace rufo utrinque striga nigra e capite ad angulos posticos 3 elytris 
pone medium fascia latissima postice angulata et fere ad apicem extensa rufa; abdomine 
obscure rufo. 
Syn.—Paristemia platyptera, Westw. in Ann. Nat. Hist. October 1841. Long. corp. 
lin. 123. Lat. elytrorum, lin, 53. 
Habitat in Africa tropicali. In Mus. nostr. Communic. D. Raddon. (Fig. 1 a. maxillary 
palpus; fig..1 6. labial palpus; fig. 1 ¢. extremity of pro & meso-sterna; fig. 1 d. 
mesosternum, seen sideways. ) 
Species I].—Paristemts Apicatis, Westw. (Plate 64, fig. 2). 
P. nigra seticea, capite linea media fulva, prothorace fulvo linea tenui media alterisque 
duabus lateralibus scutelloque nigris; elytris ad apicem nigris plaga antice in angulum 
acutum versus basin extensa, corpore subtus nigro, prosterno et mesosterni parte elevata 
fulvis. 
Long. corp. lin. 93. Lat. elytrorum, lin. 43. 
Habitat in Africa tropicali. In Mus, D. Turner. 
Obs.—The antenne are unfortunately broken off at the 7th joint; they are, however, 
evidently longer than in the former species, which is therefore to be regarded as a female, 
and this as a male. 
SAPERDA CARISSIMA, Westw. (Plate 64, fig. 5). 
Annals of Nat. Hist. October 1841. 
S. brevis opaca, supra viridi-lactea, pronoto vittis tribus longitudinalibus brunneo-fulvis, elytris 
fascia lata irregulari (in medio interrupta) ex humeris fere ad suturam ducta maculaque 
magna communi discoidali brunneo-fulvis ; his etiam guttis 10 nigris rotundatis ornatis. 
Long. corp. lin. 5. 
Habitat in Africa tropicali. In Mus. D. Raddon, Parry, Hope, &c. 
NEMOTRAGUS. Klug. 
I am not aware whether any characters have hitherto been 
published by Dr. Klug, of the genus instituted for the reception 
of the interesting insect represented in fig. 4. It is to the kind- 
ness of that distinguished entomologist that I am indebted for my 
specimen, which I received from him in 1835, since which period a 
considerable number of individuals have been obtained by one of 
the London dealers in objects of natural history. In this uncer- 
tainty I shall merely notice that its greatly elongated form, large 
* The undescribed genus Pteroplatus of Dejean’s Catalogue, composed of three Brazilian 
and Mexican species, is evidently also closely allied to these insects.
