exception of Cicadellidae, and was especially conspicuous in 

 Fulgoridae. 



In Cicadellidae, the amount of clotted material varied greatly and 

 appeared scarcer than in the other groups listed above. 



Pattern IV was observed in the samples of Cixiidae, Flatidae, and 

 Issidae. However, in Flatidae, pattern I was found in Carthaeomorpha 

 rufipcs (table, note n), a species in which pattern IV had been 

 recorded previously in the only specimen available (Gregoire, 1957, 

 p. 16). Pattern I appeared also incidentally in Anormelis nigrolim- 

 bata and in Paradascalia nietvi. Pattern IV, observed to occur pre- 

 dominantly in the few samples examined till now, is then questionable 

 as being representative of Flatidae, a family which requires further 

 investigation. 



3. Coleoptera. 



The patterns predominant or representative in several groups 

 formerly investigated were seen again in the present material: pat- 

 tern II in Scarabaeidae (Rutelinae, Dynastinae), pattern III in 

 Elateridae and in Tenebrionidae, pattern I in Meloidae (note 22), 

 Cerambycidae (very substantial coagulation), pattern IV in Cur- 

 culionidae. 



Pattern I, alone or associated with pattern II ( = pattern III) was 

 recorded in specimens of Cebrionidae and of Lymexylidae, two fami- 

 lies not represented in our former data. 



In the other groups listed in the table, scarcity in the material, large 

 variations at the individual, specific, and generic levels, already noticed 

 previously, do not permit conclusions about the pattern predominant 

 or representative of these groups. 



In this and in former studies (Gregoire, 1957, p. 22 ; Gregoire and 

 Jolivet, 1957, pp. 22 and 23), absence or scarcity in clotting substances 

 was observed in several specimens of Eumolpidae and of Cassidinae. 



In the present material, pattern III was recorded in one (Stilodcs) 

 out of 3 specimens of Chrysomelidae s.s., a family involving genera 

 with obviously predominant patterns (see 1955, p. 114: Chrysolina, 

 7 species: patterns I and III; Timarcha, 5 species: patterns I and 

 III). 



4. Panorpoid Complex. 



The present results are in agreement with former data with regard 

 to Mantispidae (pattern IV: see Gregoire, 1957, p. 23), Sialodea: 

 Corydalus sp. (pattern I, instantaneous reaction: see 1955a, p. 115:
