FOREWORD 



Volumes V, VI, and VII of Fischer's Trichopterorum Catalogue (l964, 1965, 

 1966), which deal in part with the suborder Integripalpia, were published 

 between the appearance of the first part of this work in 1964, dealing with the 

 pre-imaginal stages of the suborder Annulipalpia in the USSR, and the 

 appearance of the second part in 1966, which covers the Integripalpia. 

 Fischer's work deals with the families Phryganeidae, Molannidae, 

 Calamoceratidae, Odontoceridae, and Leptoceridae, the pre-imaginal 

 stages of which are described here. 



These volumes of Fischer's Catalogue contain many new synonyms, some 

 of which are included here. This made it necessary to correct some names 

 used in the introduction of the first part; these corrections appear at the 

 end of this book ("Errata to Vol. II, No. 1 "; p. 700). 



During the preparation of the manuscript, we consulted Dr. F. Fischer, 

 author of "Trichopterorum Catalogus" in the Netherlands. We are deeply 

 grateful to him for his great courtesy and attention in answering our queries. 



Figures 33, 35, 49, 65, 74, 88, 89, and 128 were prepared by the late 

 S. M. Shteinberg. Most of the illustrations were made by N. L. Orshanskaya 

 and M. N. Kandybina, to whom we are very grateful. 



Our co-worker M. N. Kandybina spent much time and effort in the 

 preparation of this work, laboratory studies, writing the manuscript, and 

 in preparing samples, drawings, plates, etc. She showed great competence 

 in her work, and we are very indebted to her for all her help. 



We are also grateful to Senior Technician E. A. Tetyuev for his constant 

 assistance in many aspects of our daily work and for the preparation of 

 the additional list of references. 



Our sincere thanks are also due to Professor Strelkov, editor of this 

 work, who devoted his untiring assistance.
