and so thoroughly fastened in place that the bag bears the resemblance of a twig 

 closely covered with scale-insects ; the silk appears to be pale grey in color, 

 but is so densely covered v^ith fragments that it is impossible to see it except 

 at the two ends of the bag ; the caudal end of the bag is evidently too small for 

 the male moth to simply push a round hole through it, and this end is split in 

 two places for a length of about 3 mm. 



Type locality: Sells P. O., Indian Oasis, Pima Co., Ariz. (O. C. Poling). 



Number and sexes of types: Holotype $ , 1-15 April 1923; 27 $ Paratypes, 

 1-15 April 1923; 51 $ Paratypes, 15-30 April 1923; six of these last having 

 been deposited in the collection of Mr. F. M. Jones.

1923, Dyar, Ins. Insc. Menst., XI, 4, "gloveri"?, or nigritaf, Psyche. 



Dr. Dyar states that he sees no difference between "gloveri" and 

 nigrita; and that the authors stated the antennae of jonesi were more 

 shortly pectinated than those of "gloveri". This is incorrect; the 

 authors did not mention the name glovcrii in vohime V, number 1, of 

 the Contributions. Nigrita has longer pectinations on the antennae 

 and different genitalia from any other described species from Southern 

 United States formerly placed by the authors in Manatha. 



Apparently none of the original Glover Psychid material is in 

 existence, either in Boston, Cambridge or Washington^° ; and until 1922 

 no one else had reported rearing a small Psychid from Orange. 



Prior to that date, however, the junior author had had specimens 

 of cases found on Satsmna in Southern Mississippi, and during the 

 latter part of the season obtained living larvae^^. These cases agree 

 well with those of the Glover manuscript figure, being covered with 

 rather small fragments and appearing nearly naked. Twenty males 

 emerged and are similar in antenna! structure to jonesi but black like 

 E. confederata, practically lacking the brown tints of nigrita and 

 jonesi. The larvae at first refused to eat any of the leaves of orange 

 {Satsuma), osage-orange, maple, elm, grass, etc.. and for several days 



lOMr. Louis Swett has searched the Packard Collections, i. e., Cambridge and the Bos- 

 ton Society of Natural History. Messrs. Schaus and Heinrich have searched thru the 

 material of the National Museum. Apparently no specimens of any of the original material 

 in any stage, labeled or otherwise, is in existence in these institutions. 



llThanks are due to Mr. Kimball Harmon, who spent many hours searching orange 

 groves for this insect and found larvae in various Satsuma groves at Gulfport, Mississippi, 

 and vicinity. It is entirely due to Mr. Harmon's keen eyesight and desire to assist, that the 

 authors were enabled to obtain specimens.
