/V/',s7 jStn-.i'-. - -(Plate L>, Fig. :'>.) The newly hatched 

 bug, with legs and antenna? much longer than the body, 

 procnts indeed a most unique, appearance. In this stage 

 the nymph feeds readily on aphids, and does not hesitate to 

 attack insects considerably larger than itself. Length of 

 body, '2 nini. ; of antenna?, 4 mm. ; general color pale 

 am her, darkening after the insect has taken food. Head 

 large in proportion to the rest of the body, projecting 

 between the antennae. A transverse groove crosses the 

 head behind the dark-red eyes. Beak reaching to the 

 anterior coxae. Basal joint of the filiform antennae as long- 

 as the three outer joints. These latter are of nearly equal 

 length. Thorax somewhat longer than either head or 

 abdomen, with lateral projections on each segment. Legs 

 long and very slender. Abdomen compact, sparsely hairy, 

 with well-defined segmentation. 



The young bugs were reared on aphids found on Cor;/- 

 dalis glauca and Hammamelis vii-ijlii'ina. On July 3 nearly 

 all had passed the first molt. 



Stage. Length, 2.6 mm. General color darker 

 than in preceding stage. Form similar, but abdomen much 

 longer in proportion to the rest of the body than in fir-t 

 stage. Most unfortunately all the nymphs died soon after 

 passing the first molt. In this stage the nymphs first 

 showed the habit so common to the imago, of raising the 

 fore legs above the head upon the slightest disturbance. 

 The insects were apparently able to walk as well with but 

 four leg.- us with six.
