112 Tineina of the Central United States. 



In the pamphlet above mentioned, Prof, FreyandMr. Boll mentions 

 having bred a species from leaves of the blackberry (Eubus viUorus), 

 which they consider distinct from maUfolieUa, and described nnder the 

 name of T. cenea. They also state that they have bred an allied species, 

 which they describe as T. roseticolla. The species from the blackberry 

 I have known for several years ; I have not considered it distinct from 

 maliJolieUa, Clem., and 1 regard the specimens bred from all the 

 species of Ruhus, Pyrus, Malus and Crakegus, as belonging to the same 

 species, T. maHfoliella, Clem. T. roseticolla I have not seen ; I incline to 

 doubt its specific difference from maUfoliella. 



In the two following allied species I observe a peculiarity which I 

 have not heretofore observed in any other species, nor have I seen any 

 reference to it by any author. It is this : the third joint of the palpi 

 have two long bristle-like scales, about as long as the joint itself, 

 which spring from its base on the under side, and which I think are 

 usually appressed to the surface, so as not to be distinguished from it, 

 but which it can, and in articulo mortis al\\ays does, separate from the 

 joint, so as to form with it a letter V. 



T. ambrodceella (n. sp.) 



Lemon yellow, or, perhaps, more properly, ocherous yellow. Face and 

 palpi whitish yellow ; thorax and fore wings dusted with dark brown, 

 the dusting being almost uniform over the general surface of the wing, 

 but in some portions aggregated into lines and spots. One of these 

 lines begins on the costa, not far from the base, and passes very ob- 

 li(juely backward as far as the fold in the direction of a small patch of 

 dusting about the middle of the dorsal margin. There is a larger 

 patch of dense dusting immediately before the costal cilia, and an oppo- 

 site dorsal one, and the apex is densely dusted. The cilia are of the gen- 

 eral hue, or a little paler, with a dark brown "hinder marginar line at 

 their base. The antennee are brown, and the first two pair of legs are 

 dark brown on their anterior surfaces ; the posterior pair and the venter 

 are yellow. Alex., a little more than one fourth inch, Kentucky; 

 in Summer and Fall. 



The larva mines the leaves of Ambrosia trifida. The mine is -irreg- 

 ular in outline, longer than wide, and sordid whitish; the parenchyma 

 being eaten out entirely, except within the limits of the circular nidus, 

 in which the pupa reposes, and into w'hich the larva frequently retreats. 

 The nidus bears some resemblance to those of the beetle Metonixis laev- 

 igatus and those of some species of Lithocolletis of the flat group, as e. g., 

 L. guttifiniteUa, Clem., but it differs from mines of that character by
