LONGICORNIA. 391 
1°_4™ fusco-marmoratis ; thorace tuberculo lato conico paullo elevato mox pone medium, lateribus post 
tuberculum perparum sinuatis ; elytris mediocriter convexis, apice brevissime transversim truncatis; epi- 
pleuris verticalibus ; mesosterno lato, quadrato, prosterno acetabulo paullo angustiori. 
Long. 33 lin. 
- Hab. Muxtco (coll. Bates). 
One example. An aberrant member of the genus, approaching Leiopus, especially 
the American species allied to L. alpha. The fifth antennal joint is much shorter than 
the fourth, the remaining joints slightly and gradually diminishing in length. 
46. Leptostylus incertus. 
Cidopeza incerta, ante, p. 176. 
Belongs to the same group as the preceding species ; the pro- and mesosternum are 
equally broad. The first and third antennal joints are marbled brown and grey. The 
centro-basal tubercles of the elytra are slightly elevated and pubescent, but the smaller 
dusky tubercles arranged in rows are scarcely elevated and naked. The basal joint 
of the hind tarsi is as long as the second and third taken together. 
47. Leptostylus aspiciens. (Tab. XXIV. fig. 3.) 
L. macule (Say) quoad formam, convexitatem, etc. similis, sed paullo breviter ovatus ; subochraceo-fuscus, atro- 
fusco guttulatus, elytrisque utrinque post medium macula transversa ovata (marginem fere attingente, a 
sutura longe distante) velutino-nigra ochraceo-marginata ; capite, oculis antennisque fere sicut in L. macula, 
his vero fusco-nigris, articulis 3° et 4°, 5°, 7° et 9° dimidio basali carneo-testaceis, scapo apice infra acute 
subproducto, articulis a 5° abbreviatis, 10° et 11° brevissimis ; thorace pone medium leviter rotundato-dilatato, 
dorso zequali, punctato; elytris apice juxta suturam brevissime ac obtusissime truncatis, guttis nonnullis, 
dorso perspicue tuberculatis ; sternis pedibusque quoad formam sicut in L. macula. 
Long. 34 lin. 
Hab. Mexico, Cordova (Salle). 
One example only. Belongs to the same group as L. macula, L. leucopygus, and 
allies; but the elytra marked with two large eye-like spots, similarly to Myssodrys 
binoculata and Priscilla hypsiomoides.

4, Alphinellus carinipennis. 
A, gibbicolli affinis ; differt inter alea thorace antice mediocriter convexo ibique obtuse bituberculato. Cylin- 
drico-ovatus, terreno-fuscus, interdum linea dorsali thoracis, nebulaque vaga utrinque subdiscoidali elytro- 
rum, albo-cinereis ; capite inter antennas concavo; thorace fere sicut in Leiopo subtrapezoidali, spina
