THE CANADIAN ENTOMOLOGIST. 183 



last year through the kindness of Mr. W. F. Kirby, enables me to defi- 

 nitely determine the true Lecontei, of which I have a full series, and 

 typical forms of which are shown in figures i and 2 of the accompanying 

 plate. 



This species varies in almost every conceivable manner by the spots 

 becoming confluent in different ways, and it even mimics the forms with 

 yellow hind wings in occasionally having the white suffused with a tinge 

 of ochre yellow. But there is one way in whicii it never varies, and that 

 is that there is always a prominent process on the brown border of the 

 inner margin of primaries, nearly one-third from the inner angle from 

 which a band usually extends towards the apex. In expanse my specimens 

 vary from 44-52 m.m., the average being about 48 m.m. 



C. Leucomelas H. Sch. is only a synonym of Lecontei. being the form 

 represented in fig. 2, in which the two spots towards the apex are united. 

 Fig. 3 is only a further variety of Lecontei showing the gradual transition 

 to fig. 4, which is a true specimen of the typical Militaris of Harris, as 

 figured and described in his Insects Injurious to Vegetation. Fig. 5 

 represents a very interesting specimen which, though undoubtedly a 

 variety of Lecontei, mimics Lnterrnpto-mai-ginata (what a pity it is that 

 we cannot use Harris's manuscript name Anchora !) very closely in 

 markings. 



The form which Walker and many other entomologists have mistaken 

 for Lecontei is that figured Nos. 7-9, of which I shall have more to say 

 later on. 



The other forms described by Walker were Confinis, Contigua and 

 Conscita.
