566 Mr. C. L. Withycombe's Noti?s on 



Ulopa reiiculala Fab., present in numbers at the base of 

 the heather, where the larva must have hibernated, since 

 no trees were near. 



Chrysopa ventralis Curtis. 

 Wing expanse, 24-34 mm. 



The remarks made upon C. prasina may be repeated for 

 this species, with the exception that the ventral surface 

 of the abdomen is black. This is a very constant feature, 

 and variations in the direction of prasma are not common. 

 Habitat and time of appearance are the same as for prasina. 



Eggs and first-instar larva not distinguishable from 

 C. prasina. It may be only accidental that all eggs under 

 observation took longer in hatching (eleven to fourteen 

 days) than do those of jnasina. The difference cannot be 

 accounted for entirely by temperature, apparently. In 

 the second instar the larva is quite distinct from C*. prasina, 

 and a miniature of the tliird-instar larva. A coat of 

 debris is carried. 



Description of Third-instar Larva. (Plate XLII, fig. 1.) 



Length 6-7 mm. Body white and as 'prasina, but with more 

 black markings. 



Head blackish, markings are of little value and can often not be 

 distinguished from those of jjrasina, but the following differences 

 are sometimes present. The triangular black area on the anterior 

 margin of the head of 'j^rusina is, in venfralis, often lighter in the 

 middle and thus V-shaped. The line running to the base of each 

 antenna is darkest near the anten.na base. Eyes black; antennae 

 and palpi blackish; jaws brown. 



The shape and general colour of the body are as in prasina. The 

 middle one of the three prothoracic sclcrites is often, though not 

 always, unpigmented and aj)parently absent. In front of and 

 behind the tAvo lateral sclerites, which are always blackish, is an 

 area of black hj-podermal pigment, thus making with the sclerites 

 a black latero-dorsal band on each side of the prothorax. Meso- 

 and metathorax are less marked with black, though on the former 

 are a few small spots. At the base of each wart, however, on the 

 upperside, is a distinct black spot and a smaller one behind each 

 wart. 



The abdomen is covered Avitli the usual hooked hairs of a debris- 

 carrying form, but is practically immaculate. The ventral surface
