Hab. Nicaragua, Chontales (elt ?).—Sourn America, Amazons 1. 
At first sight resembles ZL. transversus and allied species, but of rather more elongate 
form, and well distinguished by the prominent conical side-tubercles of the thorax. 
26. Leptostylus palliatus. 
Leptostylus palliatus, Bates, Trans. Ent. Soc. 1874, p. 229°. 
Hab. Nicaracua, Chontales (Lel¢ +). 
The tubercles of the disk of the thorax being obsolete in this species, it scarcely 
comes within the definition of Leptostylus. It seems, however, better placed here than 
in Nyssodrys, to which it would otherwise have to be referred, the elytra being furnished 
with rows of sete for the most part clustered in fasciculi, as in the typical Leptostyli. 
27. Leptostylus corpulentus. 
Robustus, oblongo-ovatus, sed modice convexus, fuscus, tomento tenuissimo integumento subnudo; supra totus 
conspicue punctatus; thorace valde transverso, lateribus tumido, dorso obtusissime trituberculato, plaga 
utrinque ochracea ; elytris haud setosis, sed tuberculis obtusissimis lineatim digestis, apice singulis angus- 
tatis et oblique truncatis; antennis pedibusque rufescenti-fuscis vix fusco-maculatis ; mesosterno latissimo, 
plano. 
Long. 53 lin. 
Hab. Nicaracva, Chontales (Belt). 
28. Leptostylus trigonus. 
Parvus, subovatus, postice gradatim angustatus, modice convexus, griseo-fuscus, elytris utrinque plaga elongata 
(intus rotundata) laterali fasciculisque obscurius fuscis ; thorace antice angustato, dorso septemtuberculato, 
lateribus paulo ante basin tumidis ; elytris dorso (post scutellum) planatis lateribusque prope basin costatis, 
epipleuris verticalibus, apice breviter oblique truncatis, supra fasciculis parvis crassis lineatim ordinatis, 
Long 23 lin.
