146 ENTOMOLOGICAL NEWS [April, 'll 



During 1907 I had the privilege (due to the courtesy of 

 Mr. Samuel Henshaw) of studying Hagen's specimens in the 

 Museum of Comparative Zoology. Of two of the species 

 of the Synopsis, (the Euphaca splcndcns of Ceylon and the 

 fragment doubtfully referred to the genus Cora} I could find 

 no trace. The others I found and studied, and also two addi- 

 tional members of the group here treated, not noticed by 

 Hagen in that paper, and perhaps of later acquisition by him. 

 By the study of the venation of the developing nymphal wings 

 I was able to make closer determination of some of the forms, 

 confirming his determination of Ncurobasis, but finding his 

 Anisoplcura comes to be in fact a species of Bayadera, and 

 his Euphaca disparf to be probably Anisoplcura comes. The 

 new descriptions and figures of these forms made at that time 

 were laid aside because other matters were more pressing. 

 Recently Mr. Tillyard's rearing of the nymph of the Austra- 

 lian Diphlebia lestoidcs, * and Dr. Calvert's still more recent 

 and most welcome discovery of the nymph of Cora f have re- 

 vived my interest in the matter, and have led me to offer 

 these notes and figures for publication in the NEWS. 



The greatest interest has attached to the nymphs of the 

 "Legion Euphaea" of de Selys, doubtless because of their pos- 

 session of paired lateral filamentous tracheal gills on most of 

 the abdominal segments (a character appearing in somewhat 

 altered form in Cora}. On this account one of Hagen's types 

 was figured in Packard's Text-book of Entomology (p. 469). 

 The figure is small and inadequate for specific determination ; 

 but since it shows no spines on the frons it perhaps represents 

 the "Euphaea splendens" of the "Synopsis," which Hagen says 

 was verified by Nietner, and which I was unable to find re- 

 posing in the collection at the time my studies were made. 

 Tillyard has shown that Diphlebia lacks external paired lateral 

 gills ; and I am here describing another member of the "Le- 

 gion" that lacks them, from Jamaica. The wing venation is 

 not well enough preserved to render determination very cer-
