The larva feeds in the seed pods. It is a dirty white with the chiti- 

 nized areas about the body tubercles conspicuous, moderately large, round 

 or oval, and a dull smoky fuscous, the chitinizations becoming heavier 

 and more extended toward the caudal end; on the eighth abdominal 

 segment paired setae I are on a single chitinization ; also paired II; on the 

 ninth abdominal segment paired II, I, and III are on a single shield; the 

 setal arrangement of the ninth abdominal segment is similar to that of 

 the Olethreutidae with I and III rather closely approximate; seta III on 

 eighth abdominal segment directly anterior to the spiracle; anal shield 

 brown; anal fork developed, 6-pronged; crochets of prolegs uniordinal 

 and arranged in a complete circle, 36 to 40; skin finely granulate; tho- 

 racic legs pale; thoracic shield the color of body except for a shading of 

 yellow along hind margins. Head yellow, shading to yellowish brown; 

 ocellar pigment slight, continuous but not filling the ocellar area; setae of 

 anterior and lateral group (A 1 , A 2 , A 3 , and L 1 ) crowded well forward on 

 head ; A 1 , A 2 , and A 3 forming a slightly acute angle ; L 1 closely approximate 

 to A 3 . Full-grown larva 8 to 9 mm. long. 



The pupa is similar to that of Crocidosema plebeiana except that the 

 caudal end is more rounded. There is no cremaster. 



FAMILY AEGERIIDAE 



ZENODOXUS PALMII (NEUMOEGEN) 



Larunda palmii Neumoegen, 1891, in Ent. News, v. 2, p. 108. 



Paranthrene palmii Beutenmiiller, 1901, in Mem. Amer. Mus. Nat. Hist., v. 1, 



pt. 6, p. 316. 

 Paranthrene palmii Dyar, 1903, List North Amer. Lep., no. 4260. 

 Zenodoxus palmii Barnes and McDunnough, 1917, Check List Lep. Bor. Amer., 

 no. 6735. 

 Several specimens of this species were reared during April and May, 

 1919, from larvae collected at Brownsville, Tex., January 23 and February 

 3, 1919, by H. C. Hanson and E. L. Diven. The caterpillars bore in the 

 stems of Wissadula lozani and are usually found well down in the stems 

 at the base of the plants near the roots. The adults agreed very well 

 with the description of Zenodoxus palmii Neum. I have since compared 

 them with the type in the Brooklyn Institute and have little hesitation 

 in determining them as that species, although they are a trifle small (alar 

 expanse 17.5 to 21 mm.). 



The larvae of this family are not likely to be confused with those of the 

 pink bollworm and are easily identified by the peculiar arrangement of the 

 ocelli — that is, with ocelli I to IV grouped together forming a trapezoid 

 and V and VI well separated from the other four — and the crochets of the 

 prolegs. The latter are always uniordinal and in two transverse bands. 

 The setae on the ninth abdominal segment are much the same as in the 

 Olethreutidae.
