Rev. H. Clark on the Halticidee of South America. 409 
tinguish it from allied groups. The posterior femora extend to the 
apex, and the posterior tibie and tarsi extend beyond the apex to 
nearly the length of the elytra. 
The genus is formed on a single specimen which I received in the 
Amazonian collection of Mr. Bates. 
Caloscelis azureipennis. 
C. robusta, brevis, leviter punctata, rufo-flava, elytris cyaneis: caput inter 
oculos obsolete transverse depressum, et supra hanc foveam tuberculum 
utrinque obsoletum apparet impunctatum : thorax ad medium versus 
frontem, iterumque versus basin transverse depressus (hac depressione 
obsoleta, haud abrupta); leviter punctatus: scwtellum impunctatum, 
fuscum: elytra brevia, robusta, striato-punctata, punctis vix ordine 
instructis: corpus subtus rufum: pedes rufi: antenne fusce, art. 1-3 
flavis. 
Long. corp. lin. 33, lat. lin. 2. 
A lovely species, taken near Para by Mr. Bates. By its short and 
robust body, it will take its place near to the genus Monomacra. 
Genus Norozona. 
Ovata, robusta. Caput breve, verticale. Palpi mazillares cylindrici, 
modice elongati. Thorax transversus, margine anteriori satis excavato 
et subtiliter marginato, lateribus paulum rotundatis marginatis, angulis 
anticis depressis et subacutis, angulis posticis acutis, margine posteriori 
sinuato et marginato. Scwtellum triangulare. Elytra robusta, pone 
apicem declivia, punctato-striata, plerumque lete colorata. Antenne 
elongatulz, filiformes, art. 3 et 4 equalibus, art. 2 longioribus, sed art. 
5-11 brevioribus. Pedes robusti; femorzbus posticis infra dente brevi 
et robusto armatis; ¢zbizs posterioribus subincurvatis et versus apicem 
angulatis ; wngwiculis utrinque bidentatis, dente brevi utrinque prope 
apicem armatis. 
The genus Norozona was laid down by Chevrolat to include three 
or four handsomely marked species ; it is sufficiently well-defined, 
and may be recognized by the broad thorax, robust form, punctate- 
striate elytra, and doubly-hooked unguiculi. 
Mr. Baly has recently described three species in the ‘Annals and 
Magazine of Natural History,’ September 1865; and one other, WN. 
bifascrata, Oliv., is also recorded from Cayenne. 
The following table may aid in the determination of the species 
known or herewith described :— 
Elytra flavous, with rufo-flavous or rufous spots .. N. macularia. 
flavous, with fuscous or rufous spots ...... N. marmorata. 
pale flavous, with black markings ........ N. 14-maculata.
