60 METAMORPHOSES OF 



j a, San Paulo, April, 1878 ; contains pupae of 



I parasitical dipterous fly. 



The change to the pupa state takes place in a beautiful 

 pendent cocoon of excellent silk. The upper end of the 

 cocoon is attached to a leaf or twig, and the silk is continued 

 several inches down the twig, so that the cocoon, when torn 

 off, has a long stalk to it. 



Imago, a. 



The magnificent moth appeared on 14th March, five weeks 

 after the caterpillar was full-fed ; but I believe there are 

 many broods of this moth in the year, and the length of time 

 spent in the pupa state probably varies a good deal. 



This moth seems very liable to the attacks of a parasitical 

 dipterous fly, many specimens of which I have bred from the 

 cocoons.

LXVII. — PiNCONIA OCHRACEA. 



Genus nov. Pinconia : forewing short, broad : costa convex at the 

 end, apex almost pointed, exterior margin very oblique and convex ; sub- 

 costal slightly bent at the emission of its first branch, which starts at one- 

 third before end of the cell, trifid, the second being thrown off above the 

 end of the cell is bent downward and then curves upward to the apex, the 

 third being given off near its end ; fourtii branch bifid, emitted from end 

 of the cell, curving upward and touching the second, fifth from one-third 

 beyond its base ; discocellular bent inward, lower end very oblique, radial 

 from upper end of the cell ; a slender discoidal veinlet emitted within the 

 cell from angle of the discocellular ; third median (or lower radial) at an 

 angle before end of the cell below the upper, second and first (or lower) at 

 equal one-fifth each before the end, the two last much curved ; upper and 

 lower submedians much recurved : hindwing long, almost pyriform ; costal 

 and sub-costal apparently united to near end of the cell ; discocellular very 

 oblique, bent in the middle, upper radial from the angle, lower at half way 

 below it ; a slender discoidal veinlet emitted within the cell from below 

 upper radial ; middle median at one-half and lower at two-fifths before end 

 of the cell ; submedian and internal recurved. Body pilose ; palpi small, 

 porrect, slender ; antennae (broken) ; legs densely pilose.
