Long. 5 lin. 
Hab. Mexico, Cordova (Saldé). 
One example of this ornate and very distinct species in M. Sallé’s collection. 
6. Leptostylus leucanthes. 
L. hilari affinis, magis elongatus: supra griseo-fuscus, elytris macula magna medio-laterali, altera minore 
longe ante apicem, margine exteriore fere toto maculaque transversa prope suturam nigro-fuscis, fascia lata 
post medium cinereo-alba; thorace tuberculis lateralibus prominulis; elytris plurifasciculatis, apice 
angustatis et paullo oblique obtuse truncatis; antennis albo-griseis, articulis apice nigris, 1° et 8°-5™ nigro 
guttatis ; corpore subtus pedibusque atro-fuscis, griseo piperitis, femorum clavis annulisque duobus 
tibiarum canis. 
Long. 43-5} lin. 
Hab. Mexico, Juquila (Sallé). 
Differs from L. hilaris in being rather more slender and elongate in form, and in the 
elytra being ashy brown for a large space at the base and apex, and white in an ill- 
defined fascia a little behind the middle. The median lateral spot is also larger and 
united to the subapical marginal spot, which latter is different in position from the 
analogous spot in L. hilaris, being in a transverse line with short postmedian black 
fascia. In one of M. Sallé’s two specimens there is an additional curved black mark 
on each elytron near the suture behind the middle (as in L. hélaris), which is absent in 
the second specimen. 
7. Leptostylus spiculatus. 
Quoad formam Z. hilari similis, sed aliter coloratus: ovatus, postice declivis, elytrisque apice paullo pro- 
ductis singulatim sinuato-truncatis; obscure fuscus, thorace tuberculis quinque dorsalibus validis, elytris 
tuberculis spiniformibus passim asperatis, posterioribus singulis antice cinereo guttatis; antennis pedi- 
busque rufescenti-fuscis fusco maculatis. 
Long. 5 lin. 
Hab. Nicaragua (Sallé). 
8. Leptostylus viridescen 
Angustus, convexus, viridi-cinereus sericeo micans, elytris post medium fasciola angusta undulata lituraque 
suturali prope apicem albis; thorace parvo, lateribus vix tumido, tuberculis dorsalibus quinque validis ;
