MICROSCOPY 



The microscopical features of the reactions which characterize the 

 coagulation of the hemolymph in several supraspecific groups of 

 insects (Orthopteroid Complex, Heteroptera, Homoptera, Scara- 

 baeidae, Cerambycidae, Hymenoptera, Lepidoptera) have been de- 

 scribed elsewhere (Gregoire, 1955a, pp. 109, ill, 115, 118, 123; 1957, 

 pp. 7, 27, 28; Gregoire and Jolivet, 1957, pp. 28-33). They were also 

 observed in the corresponding groups of the present material. A few 

 particular reactions will be briefly mentioned below. 



Phasmoptera. — As repeatedly pointed out (Gregoire, 1951, 1955a, 

 1957 ; Gregoire and Jolivet, 1957) the various categories of hemocytes 

 are passively embedded in the coagulum initiated by the alterations
