On a pupa-hunting trip from Tucson to Benson and St. David on April 8, 1948, I found that the unusual cold had killed hardy tamarisks or salt cedars at St. David. Here, too, a rotting pupa found that day bore testimony to the fact that extreme cold in desert regions decimates an insect population. At Benson, where temperatures had not been so severe, an empty pupal case indicated that emergence had already taken place before April 8. The pupa is closely similar to that of M. yuccas navajo. While photographing a pupa in its tube (see Plate 16), a sort of dust devil or gust of wind from nowhere, knocked it from its tube and injured it just a few days before eclosion would have taken place. Perhaps touching another prevented emergence so that only two specimens were obtained, a male and female. These were photo- 80.
