On the third of August, 1918, a single adult Eudeiucnsia 



bassettella (Clemens) was collected by Parks in Robertson 



County from the flowers of cultivated onions. This is the only 



adult that has been seen flying at large in Texas. 



Habits. 



When the larva (plate V, A) becomes full-grown, it cuts a 

 circular to oval hole about one or one and one-half millimeters 

 in diameter through the hard body- wall of the host (plate V, 

 D, F, Ha) . This hole is then closed securely with a thin, tough 

 mesh of silken threads (plate V, Fc), after which the larva 

 crawls backward to the end of its retreat. Here it transforms 

 to the pupal stage, which is naked, (plate V, B) no cocoon 

 being spun. 



In all the infested Kcrmcs examined, the larva apparently 

 produces a more or less distinctly "U-shaped" retreat or bur- 

 row, (plate V, E) living entirely within this division and not 

 working at large throughout the body of the Kcrmes. This 

 retreat occupies the lower half of all the infested hosts and 

 nearly comes together at the ends, yet leaves a small space 

 between the ends of the ''U." 



After emerging from its pupa, the moth in some way breaks 

 the strands of silken threads over the opening cut by the larva
