weeks; i. e., egg incubation period 3-4 days; larval period 10 

 days; pupal period 8 days. 



Egg: Narrowly ovoid, non-stalked, non-sculptured, whitish- 

 opalescent, .75x.30mm. 



Larva: Naked throughout its period, upon hatching, uni- 

 colorously pale-pink, 1.50 mm. long. The adult larva is elong- 

 ately napiform and non-setose (this seems to be the characteristic 

 form of those Hemerobiids and Chrysopids having naked larvae) ; 

 dimensions, 7.50x1.50 mm. Head: small, flattened dorso- 

 ventrally, translucent, pale reddish-brown; antennae black, fili- 

 form, about 4 times the length of the head; palpi long, terminal 

 joint long and moderately thickened, basal joints greyish-lutaceous , 

 apical blackish; mandibles short, very little longer than the 

 head, and much less curved than either Chrysopa or Anomalo- 

 chrysa; pale reddish basally, darker apically, blackish madianly. 



Body: Thoracic and abdominal segments brownish-testaceous, 

 with a lateral row of irregular dark areas, forming from 1st 

 thoracic to 5th abdominal segments a pair of irregular longitudinal 

 chocolate-colored bands, with purplish shading around 1st. — 3rd 

 thoracic areas; 1st thoracic segment with lateral areas pale; ab- 

 dominal segment 1-6 each with a lateral tubercle and pale lateral 

 margins extending to segment 8, Segments 8-9 reddish-brown. 

 Dorsal vessel conspicuous and blackish-brown. Legs moderately 

 long, coxae and femora blackish, tibiae light-brown; claws 

 normal, stalk of pedal sucker much shorter than that of Chrysopa 

 or Anomalochrysa . 



Pupa: Blackish and distinctly visible through the mesh work 

 of the cocoon. 



The cocoon is relatively large 6x3 mm., and composed of 

 loosely-spun pale-yellow silk, the pupa lying freely within its 

 spacious receptacle. 



This insect appears to be common in the forests of the whole 

 group.
