Sialis flavilatera L.) ; Trichoptera: Leptonema (pattern I: see 1955a, 

 p. 116: Limnophilidae sp. and Anabolia nervosa Leach) ; larvae of 

 Lepidoptera (pattern II, see 1955a, pp. 116-118; 1957, p. 23 ; Gregoire 

 and Jolivet, 1957, p. 25), and adult Diptera (Ormiophasia bushkii: 

 pattern IV, see Gregoire, 1955a, p. 121). 



As already pointed out, pattern I frequently characterizes insects 

 belonging to relatively archaic orders (Plecoptera, see 1955a, p. 107; 

 Megaloptera, 1955a, p. 115). 



5. Hymenoptera. 



Patterns I and III are representative in several families of this 

 order (Gregoire, 1955, pp. 122-123; 1957, pp. 24-26; Gregoire and 

 Jolivet, 1957, p. 25). However, individual and specific variations may 

 mask the representative pattern of the genus or of the family when 

 only limited material is available. 



In the present (note 32) and previous materials (1957, p. 24) of 

 Formicidae, a substantial pattern I characterizes the genus Paraponera. 

 Patterns I and III were also recorded, though not consistently, in 

 several specimens of the genus Camponotus (1955a, p. 123; 1957, 

 p. 24; Gregoire and Jolivet, 1957, p. 25). 



On the other hand, no coagulation could be observed (pattern IV) 

 in seven females of Astcca sp., from which the films of hemolymph 

 were collected and prepared without interference of any artifact. 



The present observations on Vespidae (note 34), Pompilidae 

 (note 35) and Sphecidae are in agreement with those made previously 

 (pattern I and/or III: 1955a, p. 123; 1957, pp. 25-26). 



6. Odonata. 



As in former studies (1955a, p. 107; 1957, p. 26), pattern IV was 

 recorded in the only (adult) specimen of this order collected in the 

 present material. 



7. Arachnida. 



Coagulation of the blood was not detected in the present and 

 former specimens of Pedipalpa, Ixodidae (1955b, pp. 497-498). 

 Pattern IV was also recorded, in this and in previous studies, in 

 specimens of Opiliones and of Brachypelma (Theraphosidae, 

 Araneae), while other specimens of the latter genus exhibited pat- 

 tern II, sometimes substantial, sometimes incomplete (see 1955b, 

 P- 495).
