Descriptions.
(By Mons. H . d e S a u s s u r e .)
Familia P a m p h a g id a :.
Genus Xiphocera, Latr., Stal, Saussure.
The two species which follow belong to the group of
X. manmlus, Saussure., having filiform antennae, not dilated.
(Comp. H. de Saussure, ‘ Spicilegia entomologica Genevensis/
ii. 1887, p. 33.)
They differ from that species and from others of the same
group by their strongly compressed body, and can be distinguished
from one another as follows :—
a. The crest of pronotum having three ovoid pellucid fenestrae,
very distinct ; the crest entire to its apex.—X. distanti.
b. The crest of pronotum having but small pellucid fenestrae,
obsolete; the crest crenulated at its apex.—X. picta.
Xiphocera distanti, Saussure, sp. n. (Tab. IV. fig. 1.)
Fusco-grisea, valde compressa, crasse granulata. Antennae
filiformes, 15-16-articulatae, superne totae obsolete, subtus
articulis 6 primis planatae. Articuli omnes depressi, extus
acuti, facie interna angusta subrotundata, haud marginata;
articuli 7 apicales submoniliformes.
Caput confertim, inter carinas laterales sparse, granulatum.
Vertex vix declivis, a latere rectangulatus ; ejus scutellum
breve, excavatum, antice rectaDgulatum, marginibus valde
prominulis, postice rotundatum. Ejus carinulae laterales
incisse, angulis incisurae rotundatis, haud crenatis. Costa
facialis a latere parum incisa.
Pronotum utrinque inferius dense granulosum. Crista elevata,
lamellaris, supra occiput valde acutangulatim producta
(Sauss. I. c. pi. ii. fig. 7) ; ejus linea dorsalis a latere in
medio vix, antice et postice magis arcuata (Sauss. I. c. pi. iii.
fig. 23) ; ejus pars postica valde producta, nec sinuata nec
crenata, apice acuto, bidentato. Sulci 3 in crista profundi
ac fenestrati, impressiones profundas, ovatas, diaphanas
majores obferentes. Pars dorsalis pronoti verruculosa ac
sparse acute granosa.—Pedes graciles, antice haud granulati,
sed extus carinati. Femora postica haud late dilatata, ante
concha apicali coarctata (Sauss. 1. c. pi. iii. fig. 20), cristis
parum latis, supra 9-spinosa, infra irregulariter denticulata.
Abdominis segmenta lm-6m superne ante apicem spina trigonali
armata.
2 . Long. 46 millim., pronot. 16, fem. post. 16.
Pretoria, 1 $ .
Xiphocera picta, Saussure, sp. n. (Tab. IV. fig. 2.)
Statura et forma sensim ut in Z. distanti; corpore toto
sabuloso, éxcepto in parte apicali abdominis ; colore fusco,
valde albo et fiavido strigato.—Antennae 16-articulatae, de-
planato-prismaticae, supra pianse, subtus articulis 3°-8° in
