and smooth convex interstices on each side of the sutural sulcus ; in C. bidens, how- 

 ever, it differs from that species in having two carinated interstices (one of which is 

 the usually short carina of the tenth interstice, which is here prolonged to the apex) 

 between the convex interstices and the long submarginal carina. The apex of the 

 hindmost tibiae is more compressed than in the allied species, and the apical truncature 

 forms a narrow oblong, thus approaching the Acanthoceri. 



Mr. Champion obtained a large number of specimens at Bugaba. Three examples 

 from Para in my own collection offer no difference. 



10. Cloeotus nasutus. 



O. bidenti affinissimus ; differt colore saturate viridi-aeneus vel nigro-seneus ; capite crebre punctulato, vertice et 

 tuberculo obtuso frontali laevibus ; clypeo medio producto, breviter bidentato, margine leviter flexuoso, 

 genis anguste sublobatis ; tborace fere laevi, lateribus solum parce punctato, omnino marginato ; scutello 

 sparsim grosse punctato ; elytris subtilissime striato-punctatis, apice absque tuberculis, breviter impresso- 

 striatis, stria suturali profunda integra, cannula ordinaria obtusa, carina exteriore antice abbreviata : 

 tibiis posticis extus parce longitudinaliter striatis, apice laevibus.

Sufficiently distinct from the southern C. bidens by the smooth apex of the posterior 

 tibiae, as well as by its dark brassy-green colour. 



11. Cloeotus metallicus. 



Clceotus metallicus, Harold, Col. Hefte, xii. p. 45 \ 



Eab. Costa Rica, Volcan de Irazu (Sogers); Panama, Bugaba (Champion). — South 

 America, Colombia \ Upper Amazons 1 . 



One example only was obtained by Mr. Champion at Bugaba, differing in its smaller 

 size and feebler sculpture from the typical form from the Amazons. The example 

 from Irazu is more characteristic. The species differs from C. bidens in the simply 

 angulated and smooth clypeus, the more distinct hind angles of the thorax, and the 

 smooth external face of the hind tibiae. The sculpture of the apex of the elytra is 

 nearly the same. 



12. Cloeotus viridipennis. 



C. metallico et G. nitenti (Guer.) proximo affinis, tibiis posticis extus laevibus. Cupreo-nitidus rufo translucidus, 

 elytris viridi-aeneis ; capite (clypei margine excepto) arcuato-punctato, media fronte tuberculo rotundato 

 laavi ; clypeo obtusissime triangalari, marginibus, apice excepto, refiexis ; tborace arcuato-punctato, spatiis 

 laevibus, angulis posticis apice rotundatis ; scutello lsevi ; elytris fere usque ad basin striato-punctatis, 

 stria suturali versus apicem sulciformi, interstitio 2° convexo, medio interrupto, carinis apud interstitia 

 10 m et 12 m (submarginalem) elongatis acutis, medio apice tuberculis 3 vel 4 elongatis ; tibiis posticis extus 

 laevibus, truncatura latissima.
