THE CANADIAN ENTOMOLOGIST 125 



plants in the foreground, and was successful in finding, in the crown 

 of the taproot, a penultimate stage Papaipema larva, close to P. 

 cerussata, yet differing in one important detail. As this discovery 

 happened early, the remainder of the time allotted the trip gave op- 

 portunity for securing a representation, and ultimately the details 

 at hand show a distinct and undescribed species. While it would 

 be fitting to honour the discoverer, our confreres consider it will 

 be more helpful to call the species suggestively: 



Papaipema eryngii, n. sp. 



Head smooth on frons and similar to the preceding species, 

 except that the colour is a darker purple, as is also the body tufting. 

 The upper tarsal joints on all legs are prominently ringed with 

 white in this instance. Fore wing: at the extreme base a white dot; 

 the usual basal spots conspicuous and yellowish to pure white; the 

 ante-, post-median and terminal areas are rich purple brown; the 

 median field dark castaneous to red brown, becoming lighter near 

 the inner margin where it shows yellow powderings; near the apex 

 a powdery yellow patch prevails. The lines follow the character- 

 istic courses, as with the preceding, are ill defined, and except for 

 the large and brightly white marked stigmata, there would be little 

 contrast. The post-medial line is drawn sinuately from a promin- 

 ent yellow spot on the costa above reniform outward in an un- 

 even-sweep past that marking, thence obliquely and irregularly 

 to the inner margin. The subterminal line is vague, a broken 

 sprinkling of yellow scales defining a boundary of adjacent areas 

 that are for the most part concolorous. The reniform is com- 

 paratively large, a central yellowish lunulate line is surrounded 

 by seven white spots; the orbicular and claviform appear as an 

 equally pronounced marking and consist of three superimposed 

 white spots, the claviform being divided into two, the upper of 

 which is smallest and stained with yellow. Several white dots ap- 

 pear on the costa, and one outside the basal spots; fringes slightly 

 dentate. The hind wing is a dull, smoky fawn, sometimes assum- 

 ing a rosy tint and overlaid with dark purplish powderings, deepen- 

 ing near the margin into a vague sub-terminal shading, and oc- 

 casionally an outer line may be discerned. Beneath, the wings 

 are deeply powdered with smoky purple. Expanse 35 to 48 mm.
