Tbe priucipal fact in counection with these Aroa S/j/ii)iff<'s which strikes the 

 observer is the large uumber of species hitherto vecorck'd only from the West 

 Indian Islands. I have also received from Dr. Otto Standinger a number of 

 Spkingidae belonging to his i)rivate collection to name, among which are fifteen 

 species new to science, which I am describing in a paper in the next nmuber of the 

 Dresden Iris, and of which a fiUl list will appear in tlie third number of this 

 journal. 



In my article in the first number of this work the following corrections 

 should be made : — 



Meqanoton distinctum Rothsch. is identical with J/, l/i'tltin Kirby, and must 

 sink into a synonym. 



PIdi'qethontius indistincta Rothsch. is identical witli Ph. dilucida H. Edw., 

 and also must sink. 



Sphinx cossoides Rothsch. is identicnl with Sphinx reeiii (Druce), which, 

 however, is a true Sphiiu.-, and not an H>/loicu)s. 



Since my last paper I have received a large collection of S/ihingcs from C'osta 

 Rica, containing a considerable number of Amhuhjx rostralis Boisd., and A. sexo- 

 calata Grote, among which are every intermediate between the two, as well as 

 several more extreme forms, so that in future these two Amhuhjx must stand as 

 follows : Amimlyx sexoculata Grote, Ambuli/x sexocidata ab. rostralis Boisd. 



Among the Ambulyx fiunjcles from Aroa were three in which the ground colour 

 is pale sulphur yellow, and the markings are dull orange and pale violet instead of 

 bronze green. This form I propose to name thus : — 



Ambuhjx eunjcles (Herr. — Schutf.) ab. sulpliurca ab. nov. 



I have a new Cypa to describe as follows : — 



Cypa mirabilis sji. nov. 



S . l'ppcr»idc : forewings ferruginous, almost chestnut red towards the apex ; 

 basal half crossed by a rather broad baud of oclireous, narrowly bordered with 

 blackish brown ; middle of the wing with a drab grey transverse patch which 

 extends from the first branch of the median nervure to the subcosta, and just 

 touches the apex of the cell ; the patch is broadest and somewhat rounded 

 anteriorly, streaklike ])ostcriorly, bears a small blackish spot on the discocellular 

 nervules, and is sinuate opposite this spot ; between the discal drab grey mark and 

 the sinus of the inner margin the scales are partly buff ; anal and apical angles pale 

 bufi', this colour well defined ; costa also somewhat buff between cell and apex ; 

 disc crossed by one or two hairlikc brown lines which are bent inwards in the 

 middle and hooked at the costa ; the whole of the wing witli disjiersed blackish 

 scales. 



Hindwings dark chestnut, base and a snbtuargiual indistinct band, running 

 from the anal angle to the costa, somewhat lighter. 



Underside : forewings tawny, with a blackish spot at the ajiex of the cell ; disc 

 crossed by a dark brown line (like (he upperside) ; middle of tlie apical margin 

 broadly chestnut, apical and anal angles as on the upperside ; space outside the 

 discal line ochreons, with dispersed blackish scales. 



Posterior wings oclireous buff, with a faint ferruginous transverse line iiehiud 

 the cell, and a dark ferruginous one crossing the disc, corresponding to the line of
