The thoracic seg-ments distinct from abdominal. Prothorax, 

 broader than the head ,widening- anteroposterior!}', bearing an- 

 te rolaterally a pair of tubercles with radiating recurved bristles. 

 Mesothorax, much broader than prothorax, the narrow con- 

 stricted portion in front appearing to belong to the former, 

 width more than twice the length, bearing antero-laterally a 

 pair of tubercles bearing radiating recurved bristles. Meta- 

 thorax, broader than the mesothorax. Width more than three 

 times that of the length, bearing laterally a pair of tubercles 

 with radiating recurved bristles. Legs moderate, whitish-tes- 

 taceous. 



Abdomen napiform, seven-segmented, each segment with a 

 pair of lateral tubercles bearing bristles. 



The general body coloring is pale greenish-testaceous with 

 paired and irregular mottling of brown, the thoracic tubercles 

 are whitish-testaceous and much larger than those of the abdo- 

 men, the latter being of the general body coloring, pale greenish- 

 testaceous. 



Pupa case nearly globular, about 2 mm. long, formed of close- 

 ly-spun whitish silk, and usually covered with insect remains, 

 etc. 



Unfortunately the pupa of this beneficial insect is attacked by 

 an Ichneumonid parasite, which at certain times and places be- 

 comes quite numerous. 



The adult Lace-wing has been described by McLachlan as 

 follows : 



"CJirysopa niicrophya, n. sp." 



"Body yellowish testaceous ("bright green" in life.) Head 

 polished ; palpi, antennae, and legs concolorous with the body ; 

 basal joint of antennae strongly bulbose ; claws dilated internally 

 at the base. 



Abdomen apparently having a l)lackish band on either side, in 

 which are yellow (or greenish) spots ; clothed with rather long, 

 but not dense hairs.. In the male it is terminated by a broad 

 oval superior plate, concave oeneath, and ventrally by a much 

 shorter nearly semicircular plate. 



Wings vitreous, slightly iridescent, ovate, subobtuse ; neura- 

 tion strong, open ; longitudinal nercures greenish, transverse 

 and graduate nercules mostly blackish, the costal nercules pale at 

 either end, the whole set with rather long black hairs ; pteros- 

 tigmatic region elongate (very long and somewhat dilated in 

 posterior wings of male), greenish; subcosta becoming con-
