Imago. J h, ? Full-fed, March 28 ; Imago, June 25, 1878 =

The moth thus appears very nearly three months after the 

 caterpillar enters the ground. 



XIII. SOROCABA ANOMALA. 



Genus nov. Sokocaba. Forewing short, rather broad and triangular ; 

 exterior margin slightly sinuous ; costal vein straight ; cell extending half 

 length of the wing ; first subcostal emitted at one-third before end of the 

 cell, second trifid, third being thrown off at two-thirds from its base, and 

 fourth at one-half from third; discocellular oblique, bent outward near 

 upper end, radial from the angle ; two upper medians from end of the cell, 

 second from near the end, and lower at one-half before the end ; subme- 

 dian nearly straight, with a short basal lower branch : hindwiug triangular ; 

 costa extending beyond the posterior angle of forewing, exterior margin 

 scalloped, abdominal margin long ; subcostal joined to costal at a short 

 distance beyond the base, two subcostal branches emitted beyond the cell ; 

 discocellular bent outward in the middle, radial from the angle; middle 

 median near end'of the cell, lower at more than half before the end. Body 

 somewhat slender ; head small ; palpi small, porrect, pilose beneath ; 

 antennae bipectinate ; legs thickish. 



Sorocaba anomala, n. sp. Pale ochreous-brown ; forewing of a greyish 

 ochreous-brown along costal area, giving it the appearance of a broad costal 

 paler fascia ; two transverse antemedial and two postmedial slMider indis- 

 tinct brown sinuous lines ; a small brown spot at end of the cell : hindwing 

 and body ochreous-brown. Cilia reddish-brown, edged with ochreous-white. 

 Expanse two inches. 



Larva cylindrical, smooth, very slightly attenuating anteriorly, head 

 small ; horn long, slender, smooth ; of a pale yellowish olive colour ; each 

 segment, except the head, with five black transverse dorsal stripes, which 

 are joined together at the posterior side and above the spiracle ; beneath 

 each spiracle is a longitudinal black streak and a slender streak on its ante- 

 rior side ; horn black tipped. 



Pupa small ; purplish-black, spiked at apex. 



From the above description of the larva of this anomalous form of the 

 Sphingidffi, it will be seen that in its markings it mimics the larva of a 

 Danais, the resemblance being more fully carried out by the presence of the 

 long slender horn. (See fig. 15, pi. VI.) 



The genus Sorocaba is aUied to Andriasa ; Walker (Catal. VII., p. 

 1735) ; which is placed by that author amongst the Bombycida?. It is 

 also allied to Cressonia and Pseudo-smerinthus.— F. Moore.
