Described from many specimens bred by Mr. Koebele and Mr. Coquil- 

 lett. 



This species resembles in general appearance the foregoing hiccha- 

 rk(Ma Busck, but it is a smaller and neater colored insect, and easily 

 distinguished by the mottled head and the clearer, lighter basal area. 



Both are nearly related to the type of the genus. 



1 take pleasure in naming this species after Mr. D. W. Coquillett, 

 who has generously giyen me his notes on this and a few other Cali- 

 fornian Gelechiida^. 



Mr. Koebele's note on this insect is as follows: 



Collected on Bigdovia? in the beginning of March, at Los Angeles, California, quite 

 a number of larvae, which spin the young leaves in the top together, so that it 

 resembles a gall; in this they live, boring down into the stem half an inch to an 

 inch, resembling in habits the Pxdisca in tips of SoJidago. 



The larvpe, when full grown, left their tips and spun a cocoon on top of the ground; 

 also on the side of the glass and on leaves. 



Mr. Coquillett has kindly giyen me the following description of the 

 larya from his notes: 



Head yellowish brown, marked on each side with two blackish dots, of which the 

 posterior one is nearly hidden by the first segment of the body; body dull pinkish 

 white, sometimes tinged with brown on dorsum of abdomen; cervical shield i)ale 

 yellowish; piliferous spots light colored; spiracles and anal plate concolorous with 

 body; length, 10 mm. 



lives in a thin-walled oblong gall about 12 mm. long, formed of the undeveloped 

 terminal bud on Aplopappus pinifolius. Several galls, each containing a single larva, 

 were found March 7, 1886, near Los Angeles, California; one of these larvse pupated 

 April 16 and the moth issued May 18. During the following year a gall containing 

 a larva was found in the same locality, April 9, and the moth issued June 12.

The unique t3^pe, labeled by Chanil)ers in the Museum of Compara- 

 tiye Zoology, Cambridge, which, though not spread, is in fairly good 

 condition, agrees with his description, and shows that the species 

 belongs in this genus. 



No other specimen is at pi-esent known to me.
