NO. 1209. LIFE HISTORIES OF AMERICAN MOTHS— DYAR. 273 



finely white lined as before. Sul)dorstil and subventral spots creamy 

 orange, white edged, the subdorsal ones on joints 5, 0, 8 to 12, the sub- 

 ventral ones on joints 6 to 13. Thoracic feet black. 



Cocoon composed of large pieces of leaf, bitten off h\ the larva and 

 united by silk, the ends roughly projecting, resembling a nest of a 

 leaf -cutting bee. 



Food plant. — Anona UmTifolia. Larvae from Palm lieach, P'lorida. 



PERIDROMA INCIVIS Guende. 



I have given the life history of this species previousl}^ ' from notes 

 made ten years ago; but the present notes contain so many additional 

 points that I have concluded to reproduce them. The later larvai 

 passed one more molt than the former, the former omitting the 

 normal Stage II, as appears from the measurements. The width of 

 head for Stage I, as given in my first description, should be corrected 

 to 0,3 mm. 



E{i(j. — Spheroidal, the base flattened; about 40 vertical ribs, dimin- 

 ishing alternately in number to about 15 about the vertex, which is 

 coarsely reticulate; cross stria? distinct lines; dark purplish when 

 found; diameter, 0.6 mm. The eggs were laid in a large mass on the 

 leaf of a tree; the larva? fed on the grass beneath. 



Stmie I. — Head rounded, bilobed, clypeus two-thirds to vertex; 

 sordid luteus with brown flecks; ocelli black; width 0.3 mm. Cervi- 

 cal shield nearly semicircular, brown dotted, cornified, bisected ])y a 

 broad, pale, dorsal line; anal plate small, smoky. Thoracic feet black; 

 abdominal on joints 7 to 10 and 13 with smoky shields, the feet of 

 joints 7 and S small. Body cylindrical, joint 12 a little enlarged; 

 colorless, food green; tubercles small, round, black. Faint subdorsal 

 (i and ii). lateral, broader stigmata! (iii and iv) and subventral broken 

 brown lines. Tubercles normal, no subprimaries, iv behind the spira- 

 cle. On thorax tubercles i and ii separate. 



Stage II. — Head rounded, bilobed, erect; whitish, faintly washed 

 with ])rown, especially in two obscure, vertical bands; ocelli black; 

 width (1.4.5 nun. Body green, four side stripes of purplish brown, a 

 white substigmatal band between the last two, the subventral one 

 somewhat broken. Dorsum rather broadly green; feet and venter 

 pale; feet on joints 7 and 8 very short. Setae black; tubercles small 

 and obscure. Joint 12 hiunped. 



8ta(je HI. — Head whitish, ocelli black, mouth brown; a faint brown 

 ))and, curved, parallel to sutures, and one back from ocelli, below 

 which are some distinct dark l)rown reticulations; width 0.6 mm. 

 Green, uniform in size, joint 12 a little enlarged. Cervical shield 

 faintly luteous, scarcely cornified. Dorsal line white, narrow; subdor-
