406 SUPPLEMENT. 
The single Guatemalan example has fewer and less distinct grey points and lineoles 
on the elytra than the specimens from the State of Panama. One of the latter (imma- 
ture ¢) is wholly chestnut-red, with obscure minute fuscous and grey spots. 
36. Lepturges xantho. (Tab. XXIV. fig. 24.) 
L. tumidicolli affinis, sed coloribus valde diversus et L. pallidulo similis. Parvus, oblongus, fulvo-ochraceus ; 
capite nigro-fusco, thorace cinereo vittis duabus dorsalibus abbreviatis nigro-fuscis, elytris lineolis tribus 
post medium suturaque plus minusve nigro-fuscis, lituris obliquis subobsoletis cinereis ; antennis flavis, 
articulis omnibus apice anguste nigris ; pedibus pallide rufo-testaceis, tibiis apice tarsisque articulis 2°-4™ 
nigris ; thorace lato et brevi trapezoideo, spina laterali abrupte exstanti sat ante basin, lateribus ante 
spinam brevi spatio dilatatis, post spinam profunde emarginatis; elytris crebre punctulatis, apice singu- 
latim rotundatis vel obtusissime truncatis. 
Long. 24 lin. 
Hab. GuateMata, Cerro Zunil (Champion). 
Like ZL. tumidicollis and its numerous allies, much shorter and broader than L. pal- 
lidulus, and the thorax of a different form, though the lateral spines are placed 
somewhat remote from the hind margin in all these species. The anterior and middle 
cox approximate very closely, the sterna between them being reduced to mere threads. 
37. Lepturges amplicollis. (Tab. XXIV. fig. 25.) 
Anguste oblongus postice angustatus, fuscus; thorace supra fasciaque elytrorum recta basali pube sericea 
cinereo-grisea vestitis, elytris guttis nigris lineatim (prope apicem confuse) dispositis interspatiis inter 
guttas nigras griseo-lineolatis; antennis obscure rufescentibus, articulis a 3° apice fuscis, pedibus 
fuscis, femoribus basi, tibiis dimidio basali tarsisque basi flavo-testaceis; thorace mox ab angulis anticis 
rotundato-dilatato, spina laterali retrorsum spectanti prope basin, lateribus ante spinam leviter sinuatis, 
post spinam sinuato-angustatis ; elytris apice oblique sinuato-truncatis angulo suturali acuto exteriori longe 
producto, epipleuris vix verticalibus ; pedibus posticis mediocriter elongatis, femoribus sat longe peduncu- 
latis apice § 9 gradatim clavatis. 
Long. 2—4 lin. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Coloured and marked nearly as in L. physoderus, and the thorax similar in shape; 
but the general form of the body is that of Anisopodus, to which genus also it approxi- 
mates in the somewhat lengthened hind legs, so different from the Lepturges of the 
L. tumidicollis group, which have short hind legs and shorter and thicker femora. The 
gradually sloping epipleure of the elytra, however, forbid the species being associated 
with Anisopodus. 
The silky blond hairs of the thorax and base of the elytra are conspicuous only in 
well-preserved specimens. 
38. Lepturges(?) rufulus. (Tab. XXIV. fig. 26.) 
Minutus, subglaber, testaceo-rufus ; elytris utrinque dimidio apicali nigris, litura arcuata a margine post humerum 
usque prope suturam lineaque oblique post medium suturam haud attingente, griseo-albo tomentosis, 
antennis articulis 1°-4™ apice femoribusque apice fusco-nigris ; fronte valde convexa, oculis parvis; thorace
