They differ from that species and from others of the same 

 group by their strongly compressed body, and can be distin= 

 guished from one another as follows : 



a. The crest of pronotum having three ovoid pellucid fenestrse, 



very distinct ; the crest entire to its apex. X. distanti. 



b. The crest of pronotum having but small pellucid fenestrse, 



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-articulatse, superne totse obsolete, subtus 

 articulis 6 primis planatas. Articuli omnes depressi, extus 

 acuti, facie interna angusta subrotundata, haud marginata ; 

 articuli 7 apicales submoniliforrnes. 



Caput confertim, inter carinas laterales sparse, granulatum. 

 Vertex vix declivis, a latere rectangulatus ; ejus scutellum 

 breve, excavatum, antice rectangulatum, marginibus valde 

 prominulis, postice rotundatum. Ejus carinulse laterales 

 incisse, angulis incisurse rotundatis, hand crenatis. Costa 

 facialis a latere parum incisa. 



Pronotum utriuque iuferius dense granulosum. Crista ele- 

 vata, lamellaris, supra occiput valde acutangulatim producta 

 (Sauss. /. c. pi. ii. fig. 7) ; ejus liuea dorsalis a latere in 

 medio vix, autice et postice magis arcuata (Sauss. /. c. pi. iii. 

 fig. 23) ; ejus pars postica valde producta, nee sinuata nee 

 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. /. c. pi. iii. fig. 20), cristis 

 parum latis, supra 9-spinosa, infra irregulariter denticulata.

Xiphocera picta, Saussure, sp. n. (Tab. IV. fig. 2.) 



Statura et forma sensim ut in X. distanti; corpore toto 



sabuloso, excepto in parte apicali abdomiuis ; colore fusco, 



valde albo et flavido strigato. Antenuse 16-articulatse, de-
