Macq., he considered should be included in it. Giglio-Tos, 

 in Ann. Soc. Ent. Fr. p. 357 (1895), reverts to the name 

 Scione estabhshed by Walker and accepted by Rondani 

 (Archiv. Canestr. iii. 18G3) for P<ingonia incompleta and 

 m'ticjulan's, Macq. ; though he does not consider the closing of 

 the two posterior cells sufficient to distinguish this genus, the 

 species which should belong to it presenting other wide differ- 

 ences, he accepts it for the present, and places a new species, 

 tS. Alluaudi, here, lie thinks Pangonia biclausa, Schiner, 

 should be placed in this genus. 



Sehiner's description of DicUsa should be referred to for 

 the genus, which at present would include species widely 

 difierent in aijpearancc, form of i)alpi, &c. Two species in 

 the Museum Colh should be included, viz. Pangonia brevis, 

 Loew, and Pangonia submacula, Walker, having the fourth 

 posterior cell closed ; but they do not agree in other particulars 

 with the description of the genus, and P. submacula is so 

 clearly allied to Pangonia guttata that it does not seem advis- 

 able to remove them from Pangonia. 



The described species placed in this genus are : —
