(7) Coléoptères du Venezuela. 83 



Galymnus cucullatus Pasc, var. C. asperulus Pasc. — Puerto-Ca- 



liello. 



Un petit individu, se rapportant à C. asperulus, qui n'est qu'une 

 variété de taille de C. cucullatus, comme le dit M. Champion. 



On trouve au Venezuela une autre espèce : 



C. longedentatus. — Long. 9 mill. — Elongatus , convexus, 

 fuscus, ruMginoso variegatus, tuberculis prxsertim elijtrorun rubigi- 

 nosis; capite piano, leviter setuloso, tubermlis antennariis valde con- 

 vexis; prothorace transverso, antice vix sensim angustiore, lateribus 

 utrinque dentibus 6 sat longis armatis, antico longiore, sed oculum haud 

 attingente, basali lato, truncato, dorso paulo inxquali, tuberculato, medio 

 sulcato, antice cornuto, cornu sulcato, decumbente, apice dilatato et 

 emarginato, tuberculato; scutello triangulari, fere nudo ; elytris apice 

 obtusis, subtiliter substriato-punctatis , intervallis vix convexiusculis , 

 alternatim, basi prœsertim, magis elevatis, inxqualibus granulalis et 

 laxe tubercidatis, tuberculis densius setulosis ; subtus cum pedibus subti- 

 liter pubescens. — Ma collection. 



Ressemble un peu à C. variegatus Champ.; en diffère, ainsi que des 

 autres espèces, par le corselet dont les denticulations sont longues et 

 peu nombreuses, l'antérieure n'atteignant pas tout à fait les yeux.
