Lyonetia latistrigella Walsingham. 



Lyonetia latistrigella Walsingham, Trans. Am. Ent. See, X, 203, 

 1882; Busck, Proc. Ent. Soc. Wash., V, 209, 1903; Dyar, List N. A. 

 Lep., No. 6416, 1902. 



Two specimens of this interesting species were bred at Balsam, N. C, 

 from mines on Rhododendro7i maximum L. The mines were only 

 observed upon the young tender leaves which had not yet attained their 

 full size. . The mine begins as a very fine black line, continuing thus for a 

 length of about 3 cm., after which it becomes noticeably broader for about 

 the same distance, but is still to be considered a linear mine. Beyond 

 this point it rapidly enlarges to a brownish elongate blotch, 4 cm. in length 

 or more, with an average width of 5 mm. The larva leaves the mine to 

 pupate, suspending its naked chrysalis by means of a few silken threads 

 stretched across a bent leaf.

The two imagoes agree closely with Walsingham's description, and 

 exhibit no variation. They are easily distinguished from the allied species 

 by the conspicuous ferruginous patch of scales in the apical fourth of the 

 wing. 



TWO NEW SPECIES OF COLEOPTERA FROM ILLINOIS. 



BY A. B. WOLCOTT, CHICAGO, ILL. 



The two apparently new species herewith described were collected 

 by Prof. Arthur G. Vestal during the course of his biological studies in the 

 Illinois sand region, and, as the result of his investigation will, no doubt, 

 soon be published, it seems desirable that these nondescripts be made 

 known prior to the appearance of his paper. 



For the opportunity of describing these beetles I am indebted to 

 Prof. Vestal, who, with rare generosity, likewise gave me the two unique 

 representatives of the following species. 



Saprinus illinoensis^ sp. nov. 



Broadly oblong-oval, strongly convex, shining black ; the antennîe 

 dull rufous, the basal joint and the legs rufo-piceous. Head impunctate, 

 strongly margined at sides and apex ; surface with a distinct and irregularly 

 eroded chevron. Prothorax twice as wide as long; the sides rather 

 strongly convergent and feebly rounded, more strongly rounded near 

 apex ; marginal groove distinct, deep throughout ; disk feebly, rather 

 densely rugulose, more feebly so toward middle and obsolete in small 

 area at middle of base, coarsely and deeply but sparsely punctate along the
