testaceis ; capite ante oculos valde elongato, occipite thoraceque confertim punctulatis, hoc graciliter cam- 
panuliformi ; elytris sat valde elongatis, basi modice latis deinde usque ad medium citius, a medio usque 
ad apicem parum, angustatis, apice obliquissime truncatis, supra confertim punctulatis.

Hab. Mexico (Sallé), One example. 
More nearly allied to O. melampus and O. brachialis than to O. picticornis and 
O. bivittatus, which it most resembles in colour; the thorax, however, is much less 
widened posteriorly than in the same sex of the two last-named species. ‘The antenne 
are moderately thickened towards the apex. 
14. Ophistomis histrio. (Tab. XX. fig. 3.) 
Aurantiaco-fulvus, supra brevissime et densissime pilosus sed nitidus, elytris lecte variegatis ; capite ante oculos 
valde elongato et angusto, occipite confertim punctulato, fusco; thorace minus elongato, postice dilatato, 
medio perparum rotundato, confertim punctulato, margine antico fasciaque mediana valde flexuosa, versus 
discum postice oblique deflecta, apud lineam dorsalem interrupta, nigris ; elytris sat valde elongatis, basi 
latis deinde usque ad apicem angustatis (nec postice anguste parallelogrammicis), apice obliquissime trun- 
catis angulo exteriori longe producto ; supra valde inzequalibus sparse punctulatis, utrinque maculis tribus 
pallidis nigro-marginatis, viz.:—1* juxta scutellum quadrata, 2° ante medium V-formi, 3*que mox post 
medium triangulari, lituraque nigra paullo ante apicem; antennis nigris, articulis 7°-11" flavis; corpore 
subtus polito, segmentis sterni et ventris nigro-marginatis.

Hab. Guatemaa, Cerro Zunil 5000 feet (Champion). Two examples. 
Beaten from the flowers of an arborescent composite tree on the margins of the 
forest in the coffee plantations of the “ Las Nubes” estate. 
15. Ophistomis saltator. (Tab. XX. fig. 6.) 
Minor, gracilis, lavo-testaceus, nitidus (abdomine rufescente); capite supra (macula flava ante antennarum basin 
excepta), antennis, vittis duabus thoracis latis, scutello maculisque quatuor marginalibus elytrorum, nigris ; 
pectoris linea laterali, ventrisque segmentorum marginibus, nigris ; pedibus nigris, femoribus (apice excepto) 
flavis ; capite ante oculos sat elongato, discrete, thorace sparsissime, punctatis, hoc elongato-triangulari 
angulis posticis longe spinosis ; elytris abbreviatis, a medio usque ad apicem angustis, apice utrinque 
sinuato-truncatis spinosis, supra sparsissime punctulatis, apud suturam depressis. 
Antenne ¢ apicem fere elytrorum attingentes modice inerassate, 9 breviores ab articulo 5° incrassate. 
¢. Segmentum ultimum ventrale elongatum basi integrum, deinde profunde concavum lateribus compressis 
(nec lobiformiter elevatis), apice in spinam productis. 
9. Color magis fulvus, pedibus testaceo-fulvis, tibiis apice tarsisque nigris.

Hab. Panama, San Feliz, Chorcha, San Lorenzo, Tolé (Champion). 
The four marginal black spots of the elytra are, in the male, placed thus :—one below 
the shoulder, small, and sometimes wanting ; one near the middle, triangular, not reaching 
the suture; one behind the middle, reaching the suture; and one occupying the apex and 
often nearly blended with preceding. In the female the four spots are detached and 
(the apical one excepted) rounded. 
Mr. Champion says this species flies about bushes and flowers in openings in the
