mnigin, and not including the smaller trans- 

 verse nervure, but a little anterior to it ; 

 a broader and not quite parallel band mid- 

 ^vaJ to the tip, including the-larger trans- 

 verse nervure and an equally broad band at 

 tip not arquated: iergipn purplish toward 

 the tip : /o;se;-5 pale jellowish: feet pale 

 honev-jellow, 



Length less than one-fifth of an inch. 



Dr. Harris appends to this " Ortalis 

 acne a Wied." 



Baron Osten Sacken sends us the 

 following note regarding this insect : — 



Besides the Trypefa trifasciata Say, 

 1 83 1, which you enquire about, there is 

 an Ortalis trifasciata Say, Journ. Acad. 

 Philad., vi, 184 (1830) ; Compl. Writ., ii, 

 368 (compare my Catal, 1878, p. 186). 



This latter, according to Loew (1. c.) 

 is a- synonym of Chaetopsis (^Ortalis) 

 aenea Wied. But this synonymy can be 

 accepted only if we read in Say's de- 



scription "connected with the second 

 band by the posterior margin," and not 

 by the costal margin, as Say has it 

 (Comp. his description with the figure 

 of the wing in Monogr. N. Amer. Dipt. 

 iii, tab. 9, fig. 19). Loew, 1. c, iii, 171, 

 line 10 from bottom, has overlooked this 

 discrepancy. However, the species being 

 very common, the synonymy is very 

 probable. 



The Trypefa trifasciata Say, New 

 Harmony, 183 1, from Louisiana, is 

 evidently likewise a Chaetopsis, and 

 perhaps the same as C. debilis Loew, 

 Monogr., iii, 172, from Cuba. Compare 

 the figure of the wing (1. c, fig. 20) 

 with Say's statement " an equally broad 

 band at tip, not arcuated."' Try p. trifas- 

 ciata Say should therefore be placed 

 provisionally after debilis, as a possible 

 synonym, but with a query. — C. R. 

 Osten Sacken. 



EARLY STAGES OF TRIPTOGON MODESTA. 



BY C.\ROLINE G. SOULE, BROOKLINE, MASS. 



On July 13th, 1S98, a battered specimen 

 was brought me, found under an electric 

 light in Brandon, Vt. At about 3 p. m. the 

 moth began laving eggs and the following 

 morning had laid eightj-four. On July 14 

 and 15 she began laying at about 3 p. m., and 

 during these afternoons and nights laid 

 thirty-two and sixteen eggs respectively. 



These eggs were 2.5 mm. long and nearly 

 2 mm. wide at tlie widest part, ovoid, green- 

 ish gray — -looking greener at night — and 

 having a pearly lustre. On the second day 

 they became heliotrope-color. On July 20th 



they became greenisli, showed the larvae dis- 

 tinctly, and the first-laid eggs hatched, giving 

 an egg-period of barely seven days. 



Young larva — -length 7 mm., slender. 

 Head round, pale green. Body very dark 

 green, the dorsum looking as if undershot 

 with black, except the last two segments 

 which were pale green like the head. The 

 body was rough, and had pale green subdor- 

 sal lines from the head to the tips of the 

 anal props. These lines became yellow two 

 days later. There were seven pale-green 

 obliques rougher than the body. The legs
