Amazons (Bates). 



This is the most variable species of the genus. 



A. Basal fascia consisting of 3 yellow dots near the scutellum, 

 and a large humeral patch, 2—4 flexuous, narrow, 6 — 6 confused 

 together (2 — 3 generally approximate). 



B. Basal fascia reduced' to 3 or 4 yellow dots, 2 — 3 united in a 

 broad band, or 2 — 5 confiised inextricably. (This is the described 

 form and the most abundant). 



C. Larger, basal fascia almost entire, 2 — 3 united in a band 

 narrowed at the suture, 4 — 5 united, near the apex. 



D. Black, with 2 or 3 yellow dots at the base. 



Erotylus Nautae, sp. n. 



This is difficult to separate from E. incomparahilis, but it is 

 rather more strongly and closely punctate, the basal fascia is red, 

 2 — 3 generally united, the others fragmentary, nearly black 

 varieties are apparently common. L. 9 lin. 



Nauta (Bates).
