Brief note in answer to correspondent. Alaptus excisus Westwood 

 the smallest insect known to date, being but .17 mm. long. Probably 

 parasitic on the eggs of a coccid.

Red Scale. Insect Life, United States Department of Agriculture,

Alaptus sp., evidently caecilii Girault, reared by Coquillett in 1887 

 or 1888 at Los Angeles, Califoi'nia, from orange leaves infested with the 

 "Yellow Scale" and therefore at first thought to be parasitic on that 

 insect; afterwards reared in large numbers from the eggs of Caecilius 

 aurantiacus Hagen and is therefore most probably not a coccid para- 

 site, the true host eggs being overlooked in the first rearings.
