Arctiidae 



that scarcely two are exactly alike in the amount of black 

 or white displayed upon the fore wings. The reader will 

 do well in this connection to consult the Proceedings of the 

 United States National Museum, Vol. X, pp. 338-353, where 

 Prof. John B. Smith has written upon the subject, the Canadian 

 Entomologist, Vol. XIX, p. 181 et seq., where Mr. H. H. Lyman 

 has presented his views, and the Plate given by Mr. F. A. 

 Merrick in the Entomological News for 1903, in which the 

 extreme variability of H. lecontei in a given locality is 

 illustrated. 



(1) Haploa clymene Brown, Plate XVII, Fig. 7, $. (The 

 Clymene Moth.) 



Syn. interruptomarginata De Beauvois; comma Walker. 



This is one of the most constant species of the genus, 

 and may easily be recognized by the figure we have given upon 

 the plate. It ranges from southern New England to Georgia, 

 and westward to the Mississippi. The larva feeds upon 

 Eupatorium it is said, and the writer believes that the state- 

 ment, which has been called in question, is correct, for, although 

 he has never reared the larvae to maturity himself, he has observed 

 the female moth ovipositing upon this plant in southern Indiana. 

 It is also said to feed upon willows. 



(2) Haploa colona Hiibner, Plate XVII, Fig. 2, 9. (The 

 Colona Moth.) 



Syn. Carolina Harris. 



Form consita Walker, Plate XVII, Fig. 5, $ . 



Syn. lactata Smith. 



This species, which is the largest of the genus, is very 

 variable in the amount of the black shown upon the fore wings. 

 We give two extremes. Other forms are recognized. The 

 insect has its metropolis in the southwestern States, though it 

 occurs also very sparingly in the northern Atlantic States, and 

 more commonly in the southern Atlantic States. It is common 

 in Texas.
