sequans, margine anteriore valde excavato, angulis anticis rectis, 

 lateribus subrotundatis, marginatis, angulis posticis obsoletis, basi 

 transversa, disco Isevi. Sen tellum tr[Rngu\are,]seve. iVy^ra parallela, 

 brevia, robusta, thorace paulum latiora, punctata (punctis confusis, 

 jnoequalibus) ; antenna vel filiformes vel incrassatse ; in c? penitus 

 corpus ipsum longitudine sequantes, et ad basin valde robustse, com- 

 pressse, sensim versus apicem attenuantur; art, 1° valde ad apicem 

 ampliato, 2° et 3" minoribus, brevioribus, et subsequalibus, 4°, 5° et 

 usque ad 1 1'" longitudine subsequalibus, latitudine sensim attenuatiori- 

 bus ; in $ antennse filiformes ; pedes robusti, satis breves, femoribus 

 subincrassatis, tibiis versus apicem robustioribus et ad insertionem 

 tarsorum subtus excavatis ; unguiculi ab infra breviter utrinque bi- 

 dentati. 



This diagnosis is based on a Chilian species, Ccelomera mutans 

 of cabiuets, which is veiy different from all allied groups, not 

 only by reason of its shorter and more robust form, but also by 

 the largely developed basal joints of the antennse in the male. 



P. mutans. 



P. et colore et maculis incertus, flavo-viridis vel fuscus, thorace et 

 elytris, vel neutro vel utroque, nigro maculatis ; caput longitudi- 

 naliter oblique foveolatum, rufo-flavum ; thorax rarius punctatus, 

 vel flavus vel nigro maculatus, maculis quatuor (duabus mediis 

 et una utrinque postmedia laterali) ; scutellum impunctatum ; 

 elytra punctis subordinatis minutis, plerumque flava, sed ali- 

 quando maculis nigris juxta basin transverse ordinatis, maculisque 

 • etiam juxta apicem ; antennce nigrse, flavo annulatae ; corpus subtus 

 in S abdominis apice fortiter ad medium foveolato, fuscescens, 

 abdomine aliquando rufo ; pedes rufi, tibiis et tarsis nigris. 



Long. corp. lin. 3-4 ; lat. lin. l|-2. 



The head-quarters of this species is Chili, where it would 

 appear to be abundant ; it is widely distributed. I have re- 

 ceived specimens from Brazil and also from Bolivia. 



Genus VIII. Pachytoma. 



Eobusta, brevis, parallela. Caput breve, verticale. Palpi maxil- 

 lares graciles, elongatuli. Thorax declivis, elytris paulum at- 

 tenuatior, angulis anticis prominulis, lateribus paulum curvatis, mar- 

 gine basali subsinuato ; disco laevi, punctato. Scutellum triangulare, 

 apice truncato. Elytra brevia, robusta, confuse punctata. Antenna; 

 filiformes, robustse, art. 1° longissimo, 2° brevi, 3", 4° et 5° subeequali- 

 bus. Pedes robusti, unguiculis pectinatis. 



1. P. Westermanni, Dej. Cat. 



P. e majoribus, fusca, antennis, pedibus et corpore subtus nigris ; 

 caput longitudinaliter foveolatum, punctatum ; thorax crebre et 

 fortiter punctatus ; scutellum nigrum ; elytra crebre punctata ;
