9- — 5 mm. — Head. — As in confluens to the extent of the italicized charaoteis 

 in the description of that species; anteunse twenty -six jointed, tlie pedicellum 

 brownish in part, the scape yellowish testaceous and brown; mandibles yellow, 

 reddish brown at apes, palpi yellowish. In other respects essentially like con- 

 fluens, dorsum of abdominal segments beyond the third stained with brownish. 



One specimen, with the !-aine data as ^4. confiueiis. 



Aniorphota cunfluen!<i mutation h. 



9 - — A little longer than mutation a, but colored almost the same; areolet dis- 

 tinctly petiolate, the petiole about as long as the shortest side of the areolet ; au- 

 teunge twenty-seven jointed. 



One specimen, same data as type, 



% . — Differs from the 9 as follows: eyes narrower, about equal to three-fourths 

 the distance between the eyes at base of clypeus, the cheeks about two-thirds as 

 wide as the eye; antennse thirty-one jointed, proximal trochanter of posterior 

 legs about entirely black. 



One specimen, same data as type. 



Ainorphola conflueus mutation c. 



9- — Differs from mutation b in having the areolet just sessile, the areolet re- 

 taining its trapezium shape as in the type. 



One specimen, same data as type. 



% . — Specimen a degree removed from sessile, i. e. slighly petiolate (antenns" 

 broken). Anomalous in having an ovoid opening in each discocubital cell. 



One specimen, same data as type. 



Aiuoi'pliota galTe!>itoiiensis n. sp. 



Related to basilaris, but very distinct in size, structure and color. 



9. — 4 mm. —Head. — As usual, with the anterior aspect dull, the posteiioi- 

 aspect more or less shining, minutely sculptured ; face, clypeus and malar space 

 minutely granular, inconspicuously clothed with silvery pubescence, appearing 

 bare; cheeks about half the width of the eye, the latter a little less than two- 

 thirds as wide as the space between the eyes at base of clypeus; ocelli arranged 

 about as in confluens: malar space about as high as the scape is long, antennae 

 twenty-six jointed, scape and pedicellum together as long or a little shorter than 

 the second joint of the flagellum, distinctly shorter than the first joint; black, 

 excepting the appendages; antennae very dark brown, with the scape, pedicellum 

 and first joint of the flagellum more or less pale brown, mandibles yellow, red- 

 dish brown at apex. 



Thorax with the usual similarity to the head in sculpture; basal area forming 

 an equilateral triangle or very nearly, areola confluent with the petiolarea and 

 transversely rugulose, if complete, the areola would be about twice as long as 

 wide, and except for the basal apex it is spatulate, external area granular, shin- 

 ing and separated from the external median area, which is rugulose, dullish by 

 a more or less distinct raised line, angular area apparently confluent wrth the 

 rather coarsely wrinkled internal area, spiracular and middle pleuial areas con-
