Brownsville, Texas, July, on flowers of mesquite, collection 

 Brooklyn Institute. 



Tyndaris barberi n. sp. (Schwarz ms). 



Head and thorax gray with a bronzy reflection, clothed with silvery 

 pubescence. Elytra black, striate and punctate, the striations finer than 

 in the previous two species ; there are two sordid white or yellowish 

 spots on the elytra nearly reaching the thoracic suture and elytral sutures ; 

 connected with these at the lower edge are two linear spots which reach 

 the thoracic suture ; extending from these to near the apex of the elytron 

 are two linear spots (or lines) almost reaching the elytral apex, the ground 

 color showing through in three places, the central one being open later- 

 ally. The legs and underside of the body are gray black. Length 5 mm. 



Described from three specimens, two of which were taken on 

 dead "cat claw" at Florence, Arizona, June 28th, by C. R. 

 Biederman. Diligent search failed to reveal more specimens. 

 One specimen taken at Hot Springs, Arizona, June 28th, by 

 Mr. H. S. Barber. At the request of Mr. Schwarz, I have 

 named this after his assistant who captured the species and 

 who has done such good work collecting in the west. It was 

 found on an unknown shrub. This little species is very con- 

 spicuous with its yellowish maculation. The three species 

 above described are characteristic of the genus, being of rather 

 robust form, cylindrical and narrowed posteriorly, as in Ac- 

 mcsdodera. Mr. Schwarz also sent me two Chilian species, mar- 

 ginella and gayi Chevrolat, the latter being a synonym of 

 planata Castelnau and Gory. Marginella is a large black spe- 

 cies, being 12.5 mm. long. It has a yellow spot on either side 

 of the thorax, and the upper two thirds of the external margin 

 of the elytron is yellowish. Planata {gayi) is dark blue, with 

 two oblique orange spots on each elytron ; an orange line on 

 the upper third of the elytral margin, and a small orange spot 

 on the elytral margin in line with the lower oblique spot. 

 Length 7 to 11 mm. The following brief characterizations may 

 be useful in separating them from North American species that 

 may subsequently be found. The five North American species 

 may be separated as follows : 



Large black species with a median cream colored fascia cincta. 



Gray species with four dark orange spots olneyse. 



Bronzy species with four dark orange spots surrounded with blue.
