all other vegetation. The group has in general confined itself 

 to regions of the same general character Full data are not 

 at hand concerning the single species known from the lower 

 moist region in the State of Vera Cruz. Such data could not 

 fail to be of interest. 



Hemileuca mexicana Druce. 



Metanastria mexicana Druce, Biol. Cent.-Am., Lep. Het. , I, 



201, 1887. 

 Dendrolimus mexicana Kirby, Cat. Lep. Het., I, 816, 1892. 



This species was described as a lasiocampid, but, although 

 no specimens are before me, it is evident from Druce's appar- 

 ently excellent figures that it is a saturnian and a member of 

 this genus. The species was described from two specimens in 

 the collection of the late Dr. Staudinger, and are without 

 exact locality. I have therefore left them out of considera- 

 tion in the above, especially as it seems doubtful whether the 

 two sexes are correctly associated. The male is represented 

 with a dark discal mark, the female with a pale one, and there 

 are other differences that would not be expected in sexes of 

 one species. It is certainly regrettable that so many of the 

 specimens in collections of this interesting group of Hemileuca 

 should be without exact localities, as it so much increases the 

 difficulty of the study of the geographical distribution of the 

 forms. 



A NOTE ON HALISIDOTA CINCTIPES GROTE. 



Some years ago I placed Halisidota dcrcisii of Henry 

 Edwards from Arizona as a synonym of H. ciuctipes, Grote 

 from Cuba, and in this course Sir G. F. Hampson followed 

 me in the British Museum catalogue. Very recently, how- 

 ever, the Hon. Walter Rothschild has separated davisii and 

 cinctipes as species and has further proposed the name under- 

 woodi for the dominant continental form. Certain differences 

 between these forms are apparent, and it may be a matter of 

 opinion whether they should be treated as species or sub- 

 species. Cinctipes occurs in Cuba and southern Florida. As 

 compared with the continental underwoodi, the markings are 

 thin and poorly contrasted, the black edgings powdery and 

 with whitish edges. The discal markings have a tendency 

 to obsolescence, breaking from the costal marks in the Cuban 

 specimens and absent in some Florida specimens. In darisii 

 from Arizona the markings that are present are well contrasted, 

 but all those beyond the disk are obsolete or absent.
