Grote collection, has referred the species to the genus Lithacodia 

 Hbn. ; we have before us a specimen of the species identified by Hamp- 

 son as nana but doubt greatly the correctness of this determination ; 

 to our mind the reference of actheria Grt. as a synonym of nana, as 

 given in our Check List, seems more probably; of course it will be 

 impossible ever to be absolutely certain concerning the identity of 

 the species, but we would call attention to the fact that the t. p. line 

 in Hubner's figure is represented as being squarely exserted around 

 the cell, which certainly fits actheria of which we figure a specimen 

 (PI. XVIII, Fig. 4) which has been compared with Grote's type 

 and marked "exact". We see, therefore, no reason for changing the 

 conception of the species as given in our list in which Crypliia Hbn. 

 supercedes Hyperstrotia Hamp., both genera being based on the same 

 species ; the venation as given in Hampson's diagnosis is correct, veins 

 7, 8 and 9 of primaries being stalked, 10 and 11 free and no accessory 

 cell. 



Two closely allied species, flavigiittata Grt. and sccta Grt., have 

 been included in Eustrotia by Hampson presumably because a small 

 accessory cell is present although a note under the latter species calls 

 attention to a variability in the venation of the specimens under this 

 name in the British Museum collection. Typically we find that in 

 Eustrotia vein 7 is connate with 8 and 9 from the angle of the acces- 

 sory cell, 10 being free from its upper corner ; we have examined two 

 specimens of ftaviguttata and six specimens of secta (1 $ , S 9 ) and 

 find that in all cases vein 7 is distinctly stalked with 8 and 9, an acces- 

 sory cell being present but reduced in size. The stalked nature of 

 vein 7 combined with the general maculation certainly points toward 

 an association with the genus Crypliia from which indeed the venation 

 only differs in the presence of the small accessory cell ; as this however 

 is apparently constant and would represent a more primitive type 

 according to Hampson (1. c. p. 2 ) we propose the generic term Pro- 

 TOCRYPHiA for these two species, specifying secta Grt. as type of the 

 genus. 



Several species have been mixed under the name sccta in our 

 collections, which probably accounts for Hampson's remark concern- 

 ing the variability of the venation; the true secta (PI. XVIII, Fig. 7) 

 is readily recognized by the presence of a large dark patch at the 

 center of the inner margin; both Grote's original diagnosis and his
