Dec. 1900.] BuscK : New Species of Tineina. 235 



has time and desire to add truly valuable contributions to science — 

 namely the working out of life histories of these charming little 

 wonders. The opportunity is open to anyone who has eyes to see and 

 leisure time to spare in fields and woods. 



I will be glad to determine any bred material sent to me and to 

 assist with any other information on the subject, within my reach. 



That there is enough to do for many observers is shown by the 

 fact that of the 1,200 species, described from this country, the life histor- 

 ies of only a small percentage are known, and that in the District of Col- 

 umbia, where comparatively much collecting has been done, on an 

 average every tenth specimen collected during the last three years rep- 

 resents an undescribed species. 



The following are a few species only out of a large collection of 

 bred material on hand, the notes on which I hope from time to time 

 to get in shape for publication. 



I am indebted to Dr. Edw. Meyrick, of England, for notes on the 

 new genera, characterized in this paper. I sent him material of 

 these supposed new genera, and he has kindly informed me, that he is 

 not acquainted with any such generic forms from Europe or Australia. 



GELECHIID.^. 

 Polyhymno acaciella, sp. nov. (Plate IX, Fig. i.) 



Antenna dark mouse gray, white at base. Labial palpi whitish above, dark 

 gray below (that is in front). Face and head white. Thorax white with four longi- 

 tudinal dark mouse-brown stripes. Fore wings elongate, caudate, dark mouse brown; 

 in the middle of the wing from base to beyond end of cell a broad spindle-shaped 

 longitudinal white band ; between this and the dorsal edge is a short white longi- 

 tudinal streak beginning about the middle of the wing and becoming narrower and 

 fainter outwards, loosing itself in the dorsal cilise. At the end of the central white 

 band are three white streaks, one below and two above, converging towards a com- 

 mon point just before apex, in the costal cilia are three short nearly perpendicular 

 streaks converging towards the same point, which is of a somewhat lighter yellowish 

 gray color, than the rest of the wing. Apical cilia white with black tips and a trans- 

 verse dark streak above the produced tips of the wing, while below it is white with 

 gray tips and two very distinct deep black round dots one above the other at base. 

 Dorsal cilia light yellowish gray. Hind wing dark gray; cilia with a golden sheen ; 

 abdomen dark gray, anal tuft yellowish. Alar expanse 1 2. 5-14 ram. 



Habitat: Texas. 



U. S. National Museum, type no. 5353. 



Co-type in Lord Walsingham's collection.
