Mr. Sanborn has also noted it as occurring on clover {TrifoUum hajariensis)^ cowpea, alfalfa, and coffee bean (Cassia occidentalis). Late in April it often becomes so abun- dant on bur clover as to cause the plant to wither, large swarms of flies buzzing around the infested plants attracting attention to them. Like the cotton aj^his, the species is often so severely parasitized by Lysiphlebus testaceipes Cress, that it is killed out in a very few days. The

It was an arrangement such as this constantly occurring in Pteraspis dixoni that led Stensio (1958 : 292) in the belief that such a pattern signified a different mode of de- velopment, to place this otherwise obvious species of Pteraspis, not only in a new genus, Penygaspis, but in a different Order, the Traquairaspida.
