158 Psyche [October 



hair-pencil from abdominal segment VIII and seven dorsal tufts; 

 this must, we think, be attributed to inaccuracies in the drawing, 

 as it is rather improbable that the abdominal segments V-VII 

 would ever be tufted, VI and VII containing normally the evers- 

 ible dorsal glands, which indeed are present in Abbott's figure, 

 but almost hidden in the tufts; a double dorsal pencil seems 

 equally improbable. 



Allowing for these inaccuracies two larvse which we success- 

 fully bred through on apple agree well with Abbott's figure in 

 the general yellow coloration, which is quite characteristic. We 

 would describe them as follows: 



Larva. Head black with pale yellow mouth parts; body gray-green, marbled 

 slightly with ochreous and with a broad blackish dorsal band on abdominal seg- 

 ments V-IX; dorsal tufts on abdominal segments I-IV and VIII dark ochreous, 

 the latter with a long black hair-pencil; two anterior and two posterior lateral 

 black hair-pencils; tubercles pale ochreous, with numerous plumed hairs, similar 

 in color to the tufts; eversible conical glands of abdominal segments VI and VII 

 pale yellowish. Prolegs flesh color with dark lateral plate. Spiracles pale cream, 

 with black rim. Length, 40-55 mm. 



The female larva seems to undergo an extra skin shedding. From 

 the two larvse received, we bred one male and one female, which 

 we figure in the accompanying plate. Abbott's figures are not 

 good. In the male the median area is much too strongly shaded 

 with white and the basal dash too prominent; the submarginal 

 row of dark spots is more suffused in our specimen, but the white 

 spot at inner angle is even more distinct than given by Abbott; 

 the course of the t. a. line is practically straight; the line itself is 

 angled three times outwardly; the t. p. line is much as in the left- 

 hand side of Abbott's figure. Abbott's figure of the female is 

 very rough; the basal portion of wing contains far too much white 

 and the t. a. line is too regular. In our specimen there exists a 

 general diffuseness both in color and markings towards inner mar- 

 gin; the white spot at inner angle is present as in the male; the 

 hind wings are lighter than in Abbott's figure and show a distinct 

 dark postmedial line. 



O. interposita Dyar. 



Four or five larvse found on a species of pine agree very exactly 

 with Mr. BeutenmuUer's description of the larva of moniana.
