disc, between (/, and g.^, numbering from four to thirteen. In 

 only one specimen do these form a complete fourth series; in the 

 rest, they form either an incomplete series, or are just scattered 

 irregularly. In the hindwing, the terminal and discal series are 

 complete, but the internal series is very variable, being some- 

 times complete, and sometimes very incomplete, with as few as 

 seven veins in it. 



This is the type-species of the genus Psychopsis. Of the seven 

 specimens examined by me, Navas would place only one definitely 

 within Psi/chopsis; the rest are either intermediate between 

 Psychopsis and Arteriopteryx, or between Psychoj^sis and Wernzia. 

 Psychopsis gracilis, n.sp., (Plate Ixxviii., fig. 10). — -The only 

 known specimen shows the three series of the forevving complete, 

 together with a very irregular, incomplete fourth series in the 

 disc between ^j and (/._,. In the hindwing, the discal and terminal 

 series are practically complete, but tlie internal series consists of 

 only four cross- veins, not forming a continuous series, and not 

 close together in line. One would like to know where Navas 

 would place this specimen. 



Psychopsis elegans (Guer.), { = Ps. newmani Froggatt). — 

 Twenty-eight specimens of this species have been examined, most 

 of them bred specimens. The cross-venation is very variable. 

 In the forewing, the three series are always complete; but there 

 may or may not be a fourth. In some specimens, this fourth 

 series is complete, consisting of as many as thirteen veins in line; 

 in others, there is only half a series; in others again, only three 

 or four irregular veins; while, in the majority of specimens, there 

 is only one intermediate cross-vein (as in Text-fig. 1), or none at 

 all. I have seen one specimen having four complete series in one 

 wing, and only three in the other I In the hindwing, the ter- 

 minal and discal series are always complete, but the internal 

 series is very variable, being sometimes a complete series of from 

 eight to ten veins in line, and sometimes merely from three to 

 five irregularly placed cross-veins. Thus, different specimens of 

 this species might almost be placed in three of Navas' genera, 

 and we are not surprised to find this author himself placing
