HESPERIDl: ACIIALAUUS lACIDAS. 1421 



conical dots now lemon yellnw ; they form a distinct vow along the lateralline, and seem 

 to have a tendency to range elsewhere in short, longilndiiial, broken lines. Dorsal 

 line. pile, and legs as before. Length. U nun. ; breadth of head, 1.8 mm. 



Fourth slay. Does not differ from the third stage except in tlie size of the head 

 (80: 23) which is 2.5 mm. broad. 



Last stage (76; 23). Head (80: 24) black, uniform, not very heavily scabrous, the 

 rugosities having a tendency on the front to form lines converging on the mandibles ; 

 the denticles of posterior summit curved forward. Hairs uniform, short, fulvous; all 

 mouth parts black. 



Body dark green with a bluishgreen. moderately broad, dorsal line, the body heavily 

 besprinkled with yellowish orange dots on and surrounding the papillae, giving it a 

 somewhat rusty appearance ; the.se become more orange in a narrow lateral stripe, but 

 not in tlie broader and vague infrastigmatal stripe; besides, the body between the 

 brighter dots is frequently painted in black specks, generally clustered in lines 

 or small spots ; on the last three segments the rust color is more marked ; the 

 thoracic shield is black-brown, smooth, slightly shining, with short, black, non- 

 tapering hairs, the front edge of the segment pale blood red. Hairs of body pellucid ; 

 spiracles black with a slender, inconspicuous, testaceous annulus surrounded by a pale 

 areola. First pair of legs black, others color of body; the claws fulvo-testaceous. 

 Length of body, 35 mm. ; breadth of body, 5.(! mm. ; of head, 4.5 mm. ; of first seg- 

 ment, 3 mm. 



Chrysalis. (85 : 21). "Colorof anterior parts whitey brown, darkest toward head, 

 of the abdomen sordid yellow brown"; all the prominences of the head are marked 

 with minute p.apillae clustered into black patches ; similar black or blackish fuscous 

 papillae are scattered irregularly and sparsely over the thorax, sparsely and with con- 

 siderable regularity over the abdomen, being arranged very largely in transverse 

 lines; each gives rise to a short "brown" bristle, mixed with some piceous ones; 

 these bristles are stont. eiiual, truncate; prothoracic spiracles "black-brown, shining"; 

 cremaster fusco-castaneous. Length, 21 mm. ; breadth. (! ram. From a specimen 

 received from Mr. W. H. Edwards ; the colors quoted after his notes. 



Distribution (27:6). This buttei-liy inhabits most of the Carolinian 

 and Alleghanian t'aiina.s, but becomes rare in or is absent from the extremes 

 of both ; probably its natural boimdaries will be found between the annual 

 isotherms of 50°and(!8°. Petiver long ago figured it from Carolina, Abbot 

 speaks of it as " not very common" in Georgia, Grote found it at Dem- 

 opolis, Ala., and Boll in Dallas, Texas,* but Chapman failed to detect it 

 in Florida : besides northern Texas, the westernmost localities reported ap- 

 pear to be OgleCu., 111. (Allen) and Wisconsin, not rare (Hoy) ; in the 

 northern part of the United States it rarely or never reaches the limit of the 

 Alleghanian faima and it is not reported west of the Mississippi Kiver ; 

 the northernmost localities in which it appears to be found are these last 

 and Michigan (Mus. Mich. Univ.), New Jersey (Merrill, Aaron), about 

 Xew York City (Graef, Tepper, Davis) , Xewburgh (Edwards) and Albany, 

 N. Y. (Hill). 



In New England it is consequently a rare insect and confined to the 

 southern portions. It has, however, occasionally occurred in abundance in 

 New Haven and vicinity (Smith), and in Plantsville (Shepard), and New 

 Britain, Conn. (Hulbert) ; " two or three are taken every season" near 



♦Mabille gives it from " Aniirique nwiridionale ! "
