LONGICORNIA. 395 
culata gradatim clavata. Tarsi postici elongati, articulo 1° ceteris 3 conjunctis subequali. Pro- et meso- 
sternum lata, hoc latiori subquadrato. 
g. Abdomen segmento terminali dorsali angusto emarginato, ventrali latiori latiusque emarginato. 
Q. Ovipositor ultra elytrorum apices prolongatus planus, segmento dorsali lanceolato, ventrali apice obtuso. 
The slender slightly twisted horny process at the tip of the third antennal joint exists 
only in the larger well-developed individuals ; in those of intermediate size it is rudi- 
mentary, and in still smaller individuals quite absent. It is longer and narrower than 
the similar process on the sixth joint in Lagochirus, and destitute of hairs. 
1. Xenostylus sublineatus. (Tab. XXIV. fig. 5.) 
Obscure castaneo-fuscus ; elytris sutura, margine laterali lineisque discoidalibus 2-3, obscure griseis ; thorace 
disco antice obtuse bituberculato, medio plano; elytris punctulatis versus apicem et lineis utrinque duabus

Lophopzum saronotum (p. 159). 
The original description of this species was drawn up from a single specimen from 
Chontales, which seems to be defective in coloration and in the clearness and depth of 
the black markings of the elytra and legs. The following emended description is 
therefore necessary :— 
Elongatum postice angustatum, nigrum, tomento subtili olivaceo-griseo vestitum, thorace nigro-irrorato 
maculisque utrinque nigris basalibus majoribus, elytris nigro guttatis, post medium maculis sex nigris 
cano-marginatis, in fascias transversas 3 et 3 dispositis, femorum pedunculis, tibiis annulo mediano, 
tarsorumque articulis 1° basi et 4° toto pallide-testaceis, antennis articulis 3°-11™ basi anguste testaceis 
(scapo subtus valde biflexuoso haud ciliato); occipite fulvescenti maculis medio duabus nigris; thorace 
paullo~post medium tuberculo conico (interdum apice obtuso), lateribus post tuberculum valde sinuatis, 
parum angustato; elytris sat confertim sed discrete punctatis, haud carinatis, apice angustis breviter 
oblique truncatis, utrinque tuberculo centro-basali obtuso longe nigro-penicillato; pedibus elongatis, 
tarsis posticis gracilibus. 
Long. 33-5 lin.

5. Lophopeum w-flavum. (Tab. XXIV. fig. 6.) 
L. saronoto proxime affine; differt elytris pone medium litura W-formi ochracea, etc. Oblongo-ovatum, postice 
angustatum, nigrum, fulvo-griseo subtiliter tomentosum, fronte nigro-fusca, occipite nigro bimaculato ; 
thorace guttis maculisque utrinque basalibus majoribus nigris, tuberculis dorsalibus duobus nigris, tuber- 
culo laterali mediano lato acute-conico; elytris undique discrete punctatis, absque carinis, tuberculo 
centro-basali parum elevato longe nigro-penicillato, nigro-guttatis, pone medium litura majori, versus 
apicem litura minori W-formibus, ochraceis late nigro-marginatis juxta apicem macula nigra, apice breviter 
oblique truncatis ; antennis testaceo-rufis, articulis 3°-11™ apice breviter fuscis : pedibus rufo-testaceis, 
femorum clavis, tibiarum annulis duobus tarsisque medio, fuscis.
