dry air of my study, but on April ist two fine specimens were 

 found in one of the jars, and between that date and the 12th 

 several more emerged. This probably antedates by nearly two 

 months the period of their natural emergence out of doors. 



That the vitality of this tiny insect in the imago stage should 

 have been^ able to withstand the ten months abstinence from 

 nourishment, the comparatively high temperature, the com- 

 pact and dry condition of the earth in the rearing jar, and 

 even the disturbance of having its cells broken when the earth 

 was turned out for examination and being subject, through 

 this, to an unwonted, though brief activity, and yet come out 

 in a state of perfection equal to those developed under accus- 

 tomed conditions appears to me noteworthy. 



The species was kindly determined for me by Dr. Schwarz, 

 of the National Museum, as Carpophilus melanopteriis Erich., 

 with the remark : " Known from Georgia, Texas and Mexico, 

 but by no means common . The species usually found in Yucca 

 blossoms is C. pallipenjiis . ' '

It is allied to Aynmoplajiics (^A?iacrabro) Icevis Provancher, 

 described from California, but is proportionately smaller, with 

 a smaller head, and slightly different colored antennae and 

 tibiae.
