We are indebted to Miss Mary Lou Morrow, Department of Entomology, Army Medical 
Service Graduate School, for critical review of the manuscript, to Mr. T. M. Evans of that 
Department, for preparing the illustrations ; and to Mr. H. Womersley for very kindly sending us 
a series of E. asonluca n. sp. which he had studied and described in draft manuscript. The 
greater part of the joint investigation of potential vectors in North Borneo was supported by 
the Commission on Immunization of the U.S. Armed Forces Epidemiological Board. 
Summary 
Six new species of the Trombiculid genus Euschongastia , all from Borneo, are described and
