This species is closely allied to H. Jamesoni, but it is much 

 brighter on flanks, the crown is totally metallic, the bill is 

 shorter, and the female has not the rufous abdomen of H. Jame- 

 soni. 



I collected my specimens at Naranjo, and on the Volcan of 

 Irazu, Costa-Rica; but I have also some specimens from Vera- 

 gua, Columbia. I have the great pleasure to dedicate this fine 

 new species to count von Berlepsch, the celebrated German 

 Ornithologist.

It is closely allied to H. speciosa; but the colour of throat is 

 quite distinct. I compared my specimens with that type, now in 

 the British Museum. 



I have the pleasure of naming it after my friend, Mr K. Si- 

 mon, the well known Entomologist, and an enthusiastic collector 

 of Humming-birds.
