head lia.s a fuscous band, vcntrally it is whitish. Eyes black; 

 antennae and palpi fuscous or castaneous, the terminal joints of the 

 latter darker; jaws castaneous. 



Prothorax with very small warts, each of which supports but a 

 single bristle. Anteriorly the prothorax is white, but the rest is 

 dark brown mottled with chestnut or orange-brown. Scleritcs 

 blackish, consist of two latero-dorsally and two or four, generally 

 less distinct and closely approximated, in the middle line. Meso- 

 a-nd metathorax dark brown with orange-brown lateral prominences 

 bearing very small warts. Each wart supports only two or three 

 weak bristles, frec^uently bent. Below the wart is a small dark 

 brown spot. The middle part of the dorsum is dark brown with a 

 fev/ small whitish warts. There is a pair of blackish scleritcs to 

 each segment. 



Abdomen dark brov/n above, but darkest at the sides, below and 

 in the region of the lateral warts. Each wart supports several 

 stiff bristles. The dorsal surface of the abdomen is covered with 

 hooked setae. A whitish median line runs the length of the body, 

 within which is the usual dark median line. Underside of body 

 wholly yellowish- white. Legs translucent whitish to just above 

 the knees, Avhence to the tarsi they are fuscous. In pale specimens 

 this is not veiy noticeable. 



N. capilata larvae can at once be identified by the ill- 

 developed thoracic warts, the prominences bearing which 

 are orange-brov/n, and by the two black spots in the middle 

 of the dark-colom'ed head. Larvae carry debris on the 

 hooked abdominal setae, but prefer few and large particles, 

 not a dense coat of small particles. For pupation a small 

 white cocoon, 4-5 mm. long, of Chrysopid form is spun, 

 covered with debris. Winter is passed as a larva within 

 the cocoon, pupation and emergence presumably occurring 

 in spring. 



Nothochrysa should be placed in quite a distinct sub- 

 family from the rest of the Chrysopidae, for reasons 

 which, however, cannot be entered into here. The main
