LA REPRODUCTION CHEZ LES LOCUSTIENS ET LES GRILLONIENS 123 



Levdig (71) a surpris la femelle de VOdoiitura senicaiida (= Barbitistes 

 scrricaiida Fabr.) - welchcs damit beschaftigt war, seinen Legesabel in 

 die Ivilze eines vcrwittertcn Pfostens am Weggelaiidcr einzusenken - (p. aT)!, 

 en note). 



Même remarque de la part de Krauss (ji), au sujet de VOdnntura 

 alboviltata (= Leptophycs alboi'itiafa Kollar), qu'il a vu enfoncer son ovi- 

 positeur dans les plus petites fentes d'une vieille clôture de bois et y dépo- 

 ser ses œufs. L'auteur a été frappé par l'attitude de la pondeuse, attitude 

 qu'il retrouve chez Y Odontura serricauda Fischer {= Barbilistes serricaiidû 

 Fabr.) et VOdoutura caïuptoxipha Fieb. (= Isophya caïuptoxipha Fieb.) 

 qui déposent leurs œufs dans la terre. 



Au dire de Riley (74), le Alicrocenlrus relineri'is Burm. (= Orophiis 

 rctiuervis Burm.) déposerait ses œufs sur les rameaux de certains arbustes. 

 La description des préliminaires de cette ponte, description qui révèle chez 

 l'auteur un remarqualdc don d'observation, mérite d'être citée en entier. 

 - Selecting a twig of about the size of a common goose-quill, this provident 

 mother prépares it for the réception of her eggs by biting and roughening 

 the bark with her jaws for a distance of two or three inches. This bite is 

 not graduai like that made when feeding, l)ut is sudden and vigorous, the 

 insect chewing and pressing the twig each side so as to form an edge. This 

 opération is accompanied by a sudden nervous shake of the body from side 

 to side, and lasts sometimes but two or three minutes, sometimes more 

 than ten. When the opération is accomplished to her satisfaction, she 

 clutches with her front fcct the stem to be used, and anchors the middle 

 and hindmost feet for the most part upon contiguous leaves or branches, 

 and oiten quite wide apart. Then, if she bas her head in an upward direc- 

 tion (for it seems to be immaterial to her whether the eggs are placed fron!_ 

 bclow up or l'icc-j'crsaj, she begins at the lower end of the roughened por- 

 tion of the twig. and after fretting it anew with her jaws and measuring 

 and feeling it over again and again with her palpi, as if to assure herself 

 that ail is as it should be, she slowly — with much apparent effort, and not 

 without letting it partly fall several timcs — curls the abdomen under until 

 the lower edge of the curved ovipositor is brought between the jaws and 

 palpi by which it is grasped and guided to the right position - (p. i56-i57). 



Les œufs du Phajieroptcra cm l'icaiidû De Geer [=^ Scudderia fui'cata 

 Br.) - are deposited singly in the edges of leaves between the upper 

 and under cuticles - (1. c, p. i65); ceux du Platyphyllum couclViiiu Hark.
