A single example from Pinos Altos in Chihuahua (Buchan- Hepburn) differs from 

 the ordinary type of this species in being of a golden-green colour.

Eab. Noeth America, Arizona 1 . — Mexico, Pinos Altos in Chihuahua (Buchan- 

 Hepburn). 



The three examples received from Chihuahua may be referable to this species, but 

 they are 6 J lines long (which is rather larger than the size given by Dr. Horn) and 

 they have the elytra dull green instead of blue. 



Acmaeodera flavomarginata (p. 21). 



To the localities given, add : — Mexico, Villa Lerdo in Durango, Guadalajara and 

 Zapotlan in Jalisco, Tula in Hidalgo, Jalapa in Vera Cruz (Edge), Temax in North 

 Yucatan (Gaumer); Guatemala, Escuintla (Conradt). 



The specimens from Villa Lerdo are broader than is usual, with two transverse bands 

 at the apex of the elytra ; one example, however, has these bands quite irregularly 

 broken. 



The examples from Jalapa are of the ordinary form, with a single broad band at the 

 apex of the elytra ; some examples, however, have this band partially divided into two 

 by a black spot at the suture and another at the side. 



The specimens from Zapotlan are of the usual form, but have the fourth interstice 

 of the elytra more distinctly costate ; the apical bands are a little irregular, distinct 

 from each other, and there is a very small yellow spot close to the apex ; one example 

 has a transverse yellow band emitted from the apex of the lateral yellow stripe. 



The examples from Tula (and one from Escuintla) have the fourth interstice of 

 the elytra costate, but the apical bands are more or less approximate or united at 

 the middle of each elytron, as is commonly the case ; two of the examples have an 

 extra yellow spot at the apex. 



7 (a). Acmaeodera proxima. 



A. jlavomarginatce simillima ; nigra, elytris usque ad medium flavo-marginatis, ante apicem fascia lata sanguinea 



ornatis, fascia saepe maculis tribus nigris interrupta.

This only differs from the ordinary form of A. flavomarginata in having the elytra a
