2.1 iiiiii. ; l)r(':i(ltli oJ" l)()(ly. . 12 mm. : of licad, ..■■»2 mm, ; Icimtli of lateral lialrs. . is mm.; 

 hi-cadtli of same, .Oi;J mm. ; length of terminal hairs, .28 mm. 



Last st(i</(' (74:18). Head grass green, uniformly and ratiicr ahiiudantly studded 

 with minute, bluntly conical whitish tubercles, each emitting a moderately long, tapei'ing, 

 pale hair directed slightly downward; mandibles sordid green, black edged, edge of 

 cheeks at base of mandibles dtisky ; ocelli more or le.ss infuscated. Body above on the 

 thoracic segments of the same green as the head, behind this becoming gradually of a 

 lighter more yelloAvish green, marked l)y a narrow, gnsen dorsal stripe indicating the 

 dorsal vessel, which is most distinct and widest on the lifth abdominal and succeeding 

 segments and is almost wholly, if not wholly, loston the lirst four abdominal segments ; 

 on the sides, below a faintly indicated straw yellow latcn'odorsal line, the body is again 

 greener, especially in a narrow band next the line, and here again especially on the 

 posterior half of the t)ody. The infrastigmatal fold is marked by a pale yellowish 

 green line, slightly more distinct than the laterodorsal line by being edged above Avitli 

 green, and separating the green pleural area from the greenei- under surface of the body ; 

 entire surface of the body above the legs studded with not very freciuent, minute, pale 

 papillae from which spring short, pale, greenish hairs, usually minutely clubbed at the 

 tip, the eftect of which is a hoary l)loom upon the surface. Terminal horns a little 

 longer than the breadth of the anal prologs, slightly upturned, a little divergent, and 

 scarcely curved outward, regularly tapering to a ratiier blunt point, with rather nu- 

 merous subcylindrical tubercles furnished with hairs liketiiose of the body, the surface 

 of the horns of a ferruginous color, deepest on the upper inner edge, palest at the base 

 on the outer side ; legs green, the apical joints pale soi'did green : prolegs grass green ; 

 spiracles very pale testaceous. Length, 33.5 mm.; breadth of abdomen, 4.5 mm. ; of 

 head, 3.25 mm. ; length of horns as seen from above, 1.4 mm. 



Chrysalis. The whole body is of a uniform pea green mottled with paler green, but 

 the alar ridge, which is sharp and tolerably prominent, the mesothoracic ridge and 

 the ridge between the ocellar prominences are edged Avith pale straAV color. The paler 

 mottlings of the body are upon the dull scabrous elevations with which the body is 

 uniformly covered and which are most consiMcuous on the abdomen, gi\ ing it a feebly 

 shagreened appearance. The ocellar tubercles and basal wing tubercles are tipped 

 with a black dot. The spiracles are pallid Avitli dingy slender lips. The cremaster is 

 hoUoAved on all sides and its basal projections ai'e minute and tipped with fuscous. 

 Length. 1.05 mm. ; "width in middle, mm. : width at ocellar tubercles, 2.5 mm. 



Distribution (18:3). This l)utterfly extends nortlnvard to jibout the 

 annual isotherm of 4")°, southward Aery nearly but a])parently not quite to 

 the Gulf of ^Nlexieo, and westward to Texas, Missouri (Stolley, — Mus. 

 oonip. zool.), eastern and western Kansas (Snow) and Iowa (Allen, 

 Putnam). I have never heard of its being taken in Florida, and all the 

 notices of its capture in the Gulf States have been at some distance 

 from the sea coast. Abbot jfigiu'es it from Georgia, but sa^^s it is un- 

 common and Gosse records it from Alal)ama ; Mr. Belfrage says it is not 

 connnon in Texas, while ]\Ir. Allen reports it as exceedingly abundant in 

 Iowa. It is found in Wisconsin (Kirtland), in the southern half of 

 ^lichigan (Coll. Mich. Univ.), the lower parts of Ontario (Saunders) and 

 throughout most of Xew York ; occasional s})ecimcns are taken further 

 north. 



It is tolerably abundant, sometimes very connnon, in the southern half 

 of Xew Enoland, occurrino- throuohout ]\rassachusetts and the two states 

 lying south of it and in the southern extremities of Maine, Xew Hamp- 

 shire and Vermont. The most northci-n localities from which I have
