of the pupaj project about half their length from the soil and, 

 attached by the caudal end, sway back and forth rather actively. 

 In none was the beginning- of transformation observed ; speci- 

 mens partly out of the skin were several times noted. The male 

 has difficulty in extricating the very long antenna^ from the 

 pupal sheath. A field sketch made of the closely-allied E. 

 si)hiosa is herein given and shows the relative position of the 



Adult male of Kriocera spinosa O. S. emerging from the pupal skin. The coloring 

 and hair-characters are from a fully colored adult. 



l)arts of the body that are used : the first flagellar segment of the 

 antennfp is directed straight away from the body, the fourth 

 segment (second flagellar) at an acute angle to the third and 

 thence the antenna^ continue straight back to the sheath. The 

 numerous spines on the underside of the flagellum of the males 

 of E. spinosa and longiconiis have long been known and the 

 fact that they pointed away from the body noted; any use for 

 this curious development has not been suggested. We observed 

 the males in the act of withdrawing their antennae and the 

 method of procedure was about as follows: The tijis of the 

 fore femora are placed underneath the sharp spines on the 

 flagellum and by raising the leg the antenna is pulled upward 

 slightly. These spines are regularly arranged and since both 

 forelegs work in unison, the spines function as cogs and the 

 whole organ is gradually forced from its pujjal sheath. The
