EDITOR'S PREFACE. 



\- 1 have already stated in my Preface to the 'Monograph of the 

 I rylophidffl and Sphseriidae,' the entire collection- of Micro-Cok-optera In-longing 

 to the late Rev. Andrew Matthhws passed into my possession at his decease> 

 undi-r an arrangement, made Bhortly l)efore, that I should assist him in 

 publication of the before-mentioned and present works, and in issuing this 

 plement to the ' Trichopterygia Illustrata et Descripta,' I am pleased to have 

 fulfilled my obligation to my much lamented friend. It is to be regretted that 

 the Author did not live to revise these works as they were passing through the 

 press, as I fear errors have escaped notice which he, no doubt, would have 

 rectified. 



In preparing the manuscript of the present work for the press, I have only 

 corrected any obvious errors that were detected, ehiefi}* in the references, otherwise 

 the whole of the matter and system of arrangement is the Author'- own work. 



In the systematic and descriptive part of the work the Author has only 

 included those species that he had an opportunity of examining himself, and 

 for the most part contained in his own collection; others thai were only known 

 to him by description will be found mentioned in the latter part of his Preface, 

 with a translation of the original descriptions, or a short note of their leading 

 characti rs. At the end of the Prefac 7), I have given a list, in 



chronological order, of some species that he had apparently overlooked, or had 

 been described since be completed his manuscript. 



Mr. Matthews's collections, which now form part of my Museum, contain 



the types of all the Trichopterygia described by him, except twelve of tin Bpecies 



described in the present work, of which I have given a lisl at pagi LI, and 



i. colli ctions in which these may be found, for the information of anyone 



wishing to consult the types.
