markings. The male genitalia offer nothing tangible, being of a simple 

 type, not strongly chitinized or differentiated. Nevertheless, on larval 

 characters at least, the Antillean form should have a separate name. Of 

 the names proposed, timais Cramer was described from the " cote du 

 Coromandel;" amaryllidis Sepp, from Dutch Guiana, and regnatrix 

 Grote from Pennsylvania. As there is thus no name for the Antillean 

 form I propose antillium, n. sp. 



This is a case of unusual distribution. Very mzuiy of the species found 

 in southern Florida are of Antillean origin, but in this case it is clear that 

 our timais is a continental species. 



A NOTE ON THE MACROTHEClN>E 



(LepiJopiera. Pyralida) 

 By HARRISON G. DYAR 



Doctors Barnes and McDurmough have recently (Cont. Nat. Hist. 

 Lep. N. A., No. 5, p. 37, 1912) given an admirable treatment of the 

 smaU group of genera allied to Amestria Ragonot. They show that 

 Amestria falls before Alpheias Ragonot and my Cacotherapia before 

 Macrotheca Ragonot. They add two new genera to the group. They 

 give the following table to separate the genera, which 1 reproduce with 

 the nomenclature of the veins changed. 



Fore wing with 12 veins. 



Fore wing with vein 10 arising beyond 7 . . . Alpheias Ragonot 



Fore wing with vein 10 arising before 7 . Macrotheca Ragonot 

 Fore wing with 1 1 veins (8 and 9 coincident). 



Fore wing with vein 10 stalked .... Alpheioides B. & McD. 



Fore wing with vein 10 from the cell . . Decaturia B. & McD. 



I had been aware for some time that my genus Cacotherapia belonged 

 with Amestria, but had not worked out the matter as fully as has been 

 done now. Unfortunately, the authors have quite misidentified my spe- 

 cies ponda. It is a rather large, brownish moth with black irrorations 

 and not the little gray and white one that they have figured. The true 

 ponda falls in Macrotheca and not in A Ipheias. The species which they 

 misidentified as ponda may be characterized as 



Alpheias vicarilis, new species. 



Fore wing with the ground color nearly white, blotched with yeUow- 

 brown shades ; bas£tl space filled with brov^mish and dusted with black ;
