Genus Colaspoides, Laporte, 

 Baly (Ent. Monthly Mag. 1864, 134). 



C. pulchella, 



G. ovalis, punctata, Isete cserulea, nitida : caput verticale, inter oculos 

 transverse depressum iterumque ad frontem longitudinaliter foveo- 

 latum, punctatum, punctis rarius versus frontem conspersis, viridi 

 tinctum : thorax superne visua transversus, lateribus ipsis versus 

 caput obliquatis et depressis, raargine anteriore rotundato, poste- 

 riore sinuato-marginato, lateribus undique tenuiter raarginatis, 

 thorax leviter sed satis dense punctatus : scutellum ad apicem cir- 

 culare, laeve : elytra parallela, robusta, thorace latiora, punctata 

 (punctis ad dorsum crebris et fortibus, versus apicem minoribus et 

 in strias sese formantibus) ; margines elytrorum nigri apparent: 

 antennae nigrae : pedes viridi-nigri : corpus subtus viride, abdominis 

 segmentis rarius punctis ornatis. 



Long. corp. lin. 2| ; lat. lin. 1 J. 



Hab. Pulo-Penang. 



The differences of structure between Colaspoides limhata, Oliv., 

 the type of the genus, and the species before us do not appear 

 to be sufficient to separate them generically, although the former 

 belongs to a group which is sufficiently abundant in examples 

 and species in Brazil, while the latter is one of exponents which 

 are probably distributed through a large portion of the Eastern 

 Archipelago. 



Genus Colasposoma, Lap. 



1. C. cBueo-viride. 



C. parallelum, latum, robustum, breve, punctatum, nitidum, aeneo- 

 viride : caput ad frontem longitudinaliter depressum, fortiter punc- 

 tatum : thorax transversus, ad latera juxta frontem valde depressus, 

 lateribus subrectis, versus apicem paulum contractis, marginatis, 

 basi etiam subsinuata, marginata ; thorax fortiter punctatus ; 

 scutellum subcordiforme, Isevi, viridi-aeneum : elytra subparallela, 

 robusta, humeris prominulis, lateribus vix versus apicem contractis, 

 marginatis ; elytra punctate- striata ; puncta minuta, satis crebra, 

 confuse (sed versus apicem in striis vix sequalibus) ordinantur: 

 antennce rufo-fuscse : pedes nigri, tibiis tarsisque rufo-fuscis : 

 corpus subtus nigram. 



Long. Corp. lin. 4| ; lat. lin. 2. 



Hab. Pulo-Penang. 



2. C metallicum. 



C. breve, robustum, ovale, nitidum, fortiter et crebre punctatum, 

 seneo-metallicum : caput verticale, punctis confertis : thorax trans- 

 versus, lateribus subrotundatis, marginatis, angulis anterioribus 

 compressis, margine anteriore transverse, postico sinuate ; ad me- 

 diam basin fovea minuta longitudinalis apparet ; thorax pimctatus.
