bands on the elytra a little straighter at the suture ; the abdomen is more brightly 

 coloured, with the coppery colour at the sides deeper and more extended.

This species was named both in M. Salle's collection and in the British Museum as 

 A. yucatana. I am, however, unable- to find it described, and have not seen it from 

 Yucatan. It is allied to A. calcarata, Chevr., but is a trifle narrower, less opaque, and 

 the sculpture is less close and less rough ; its colour is paler, more brassy, and frequently 

 almost silvery. The thorax has the posterior angles somewhat diverging ; the transverse 

 impression at the base is only visible on each side, and in some examples is not strongly 

 marked. The first band on the elytra is near the base ; commencing on the shoulder it 

 descends a little, then ascends nearly to the scutellum, and then turns downwards to 

 the suture. The second band is rather broad, rather straighter ; it consists of two arcs 

 (one on each elytron) with a dilatation at the suture. The apical area of each elytron 

 is more or less taken up by the triangular dark spot. 



Two of the specimens (one from Honduras and one from Zapote) have the clypeus 

 violet, with green angles and a green central line. 



9. Actenodes humeralis. (Tab. II. fig. 19.) 



Elongata, sat angusta, parum nitida, creberrime punctata, senea; thorace postice leviter transversim impresso, 

 angulis posticis fere rectis ; elytris prope suturam costa (antice et postice abbreviata) instructis, sub 

 humero macula roseo-cuprea ornatis ; corpore subtus viridi, lateribus apiceque ameis.

This species is nearest to A. hopfneri. Gory, but is still narrower. The posterior 

 angles of the thorax are not diverging, they are right angles or perhaps a little acute : 

 the punctuation is fine and close ; the transverse basal impression is scarcely visible in 

 the middle. The elytra have a well-marked fine costa near the suture, and there is an
