NITIDULIDAE. 
179. Carpophilus pallipennis, Say. — Taken numerously in flowers of 
cacti, March 24th. Larvae found making longitudinal tunnels in flow- 
ers, March 31st, and pupae found April 10th, which changed to adults 
April 13th. Life cycle, from egg to adult, is about 21 days. The larvae 
bore among the mass of stamens inside the flower, also apparently in 
the fleshy portions of base of flower between the ovary and the sepals. 
The adults aid in cross-fertilization of the cacti flowers, going from one 
flower to another to deposit their eggs, or at least going from the flower 
in which they were bred to another flower in which to deposit, and mean- 
time feeding on the pollen as they burrow among the mass of stamens 
and anthers. Distr. Nebraska, Kansas and Colorado to Texas, New 
Mexico, Arizona, IJtah, California and Lower California. Reaches high
