192 Mr. E. MacLacLlan's Monograph of 



The whole insect is covered with a whitish powder, 

 which, under a very high magnifying power, has the 

 appearance of minute irregularly rounded granules, very 

 slightly attached. 



Larva with a small head and thoracic segments, and 

 large dilated abdomen, attenuated posteriorly ; lives ap- 

 parently upon Cocci, and allied insects ; spins an orbicular 

 cocoon of fine white silk. This larva was discovered 

 by Mr. Haliday (see Curtis' "British Entomology,'^ pi. 

 628, and Westwood's ''^Modern Classification," vol. ii. p. 

 49) , and has also been noticed by Dujardin. 



These curious little insects were once placed by authors 

 in the Homoptera, and also in the family Psocidce among 

 Neuroptera : but, as Westwood has shewn, their true 

 position is undoubtedly that here allotted to them. 



Genus I. Coniopteryx, Haliday. 



( =: Coniortes, Westwood ; Malacomyza, Wesmael ; Scio" 

 dus, Zetterstedt; and probably also Aleuronia, Fitch.).
