Compared with numerous specimens from Guadeloupe, the single example in the 
Sallé collection offers no other difference except its relatively rather shorter elytra. 
80. Leptostylus albescens. (Tab. XXIII. fig. 18.) 
L. pulcherrimo quoad colores similis. Sat elongatus, supra cinereo-albus (certo situ fulvescens); elytris maculis 
lateralibus duabus nigris (altera mediana magna postice viridi-senea, altera minori ante apicem) lituraque 
nigra triangulari communi suturali versus apicem ; thorace maculis elongatis basi quatuor, juxta marginem

juxta apicem angustatis, apice oblique truncatis, angulo exteriori sat producto, dorso fasciculis altis lineatim 
digestis cinereo-albis, carinisque centro-basalibus validis; corpore subtus nigricanti; antennis articulis 
1°, 3° et 4° griseo- et nigro-maculatis, 5°-11™ nigris basi griseis ; pedibus cinereis, femorum clava basi nigra, 
tibiis annulis duobus nigris ; tarsis nigris, articulis 1° et 2° griseis. 
Long. 6 lin. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One example. Resembles L. pulcherrimus in colour, but the black marks are not 
in the same position, and its nearest ally is the differently-coloured L. subfurcatus. 
31. Leptostylus diffusus. (Tab. XXIII. fig. 19.) 
L. cineraceo affinis et quoad formam simillimus sed aliter coloratus. Ovatus, convexus, cinereo-albus ; elytris. 
medio litura circumflexa-A communi, pone hance fascia lata (marginem haud attingente) maculaque 
utrinque transversali prope apicem, olivaceo-fuscis sericeis, stigmate grandi laterali subobsoleto ; thorace 
disco 5-tuberculato (tuberculo mediano-posteriori longiori et validiori), tuberculis lateralibus parvis ; elytris 
convexis valde inequalibus, grosse punctatis et aspere tuberculato-fasciculatis, apice integris ; antennis. 
testaceis scapo griseo, articulis 3°-4™ fusco-piperitis, 3°-11™ apice fuscis. 
Long. 42 lin. 
Hab. Mexico, Cordova (Sallé); Guatemaua, Torola (Champion). 
32. Leptostylus retrorsus. (Tab. XXIII. fig. 20.) 
L. diffuso proxime affinis et simillimus, sed differt elytrorum macula circumflexa retrorsa V. 
Long. 42 lin. 
Hab. Panama, Volcan de Chiriqui (Champion). 
38. Leptostylus signaticauda. (Tab. XXIII. fig. 21.) 
L. aculifero (Say) affinis et subsimilis; differt inter alia elytris apice litura communi griseo-alba V-formi ; 
obscure fuscus vel viridescenti-fuscus, elytris fascia post medium apud suturam dilatata (sepissime obsoleta) 
maculaque constanti apicali V-formi, griseo-albis ; thorace dorso 5-tuberculato, tuberculis lateralibus nullis,. 
interstitiis crebre punctato ; elytris valde ineequalibus, dorso carinatis et tuberculis fasciculisque asperatis, 
tuberibus centro-basalibus magnis, sat elevatis et multituberculatis, apice angustatis et oblique truncatis ; 
antennis testaceo-griseis, articulis apice nigris, articulis 3° et 4° fusco-piperitis, scapo quam in L. aculifero- 
longiori et graciliori. 
Long. 34-44 lin. 
 _Hab. British Honpuras (Blancaneaur); Guaremata, Cerro Zunil, Las Mercedes. 
(Champion). 
A large number of examples. The postmedian fascia of the elytra is in no specimen 
more than a narrow streak with a spot-like dilatation on the suture; and, like the
