Certainly distinct from L. leucopygus, in which the anterior margin of the grey apical 
area is arcuated. The thorax also is different in outline, the sides being much narrowed 
and sinuated behind the prominent lateral tubercles. In L. lewcopygus the thorax has 
the same form as in L. macula, Say, viz. with feebly rounded sides, and more narrowed 
in front than at the base. 
42. Leptostylus angulicollis. 
Parvus, ovatus, minus convexus, fuscus, elytris tuberculis parvis nigro-pubescentibus in series abbreviatas 
utringue quatuor ordinatis, tuberculo centro-basali compresso nigro-cristato, stigmateque laterali curvato, 
nigro, et lituris indistinctis submedianis canis; thorace lato et brevi, tuberculo laterali post mediano magno 
obtuse conico, dorso obtusissime tuberculato ; antennis articulis 1° griseo, 3°-5™ testaceis fusco-piperitis apice 
nigris, 6°-10™ pallide-testaceis apice nigris, 11° nigro; elytris apice breviter oblique truncatis ; pedibus 
griseis, tibiis nigro-biannulatis, tarsis nigris articulo 1° basi griseo. 
Long. 24-23 lin. 
Hab, Guatemata, Pantaleon (Champion). 
A dwarf species allied to L. levicauda and L. pleurostictus, but distinguished by the 
large, broad, conical lateral tubercles of the thorax and the rows of small, rounded, black, 
pubescent tubercles of the elytra. 
43. Leptostylus —— ? 
Hab. Panama, Tolé (Champion). 
A single example, much abraded, allied to L. cineraceus, but showing a transverse 
arcuated grey fascia midway between the middle and apex of the elytra, which seems to 
indicate a species different from any of the foregoing. 
44. Leptostylus —— ? 
Hab. Panama, Volcan de Chiriqui (Champion). 
A single very imperfect specimen. 
45. Leptostylus dubitans. 
Leiopo neviicorni similis a quo differt thorace tuberculo laterali submediano conico, mesosterno latiori et quadrato, 
etc. Anguste oblongo-ovatus, obscure fuscus; elytris post medium fascia antice ad suturam acute angulata 
alteraque simili multo angustiori prope apicem, cinereo-albis, elytris tuberculis nonnullis parvis setiferis 
seriatim ordinatis, centro-basalibus haud elevatis ; antennis testaceo-rufis, articulis omnibus apice fuscis,
