Mar. i, 1921 Lepidoptera Likely to Be Confused with Pink Bollworm 825 



and pinkish larva feeding on the seeds of Baptisia spp. about the size 

 and with much the general appearance of the pink bollworm. Except 

 for the complete circle of crochets on the prolegs the superficial resem- 

 blance was rather striking. The structural characters are so obviously 

 different as to prevent confusion by a careful observer. The arrange- 

 ment of setae on the ninth abdominal segment is typically olethreutid 

 (Compare PI. 103, E; 105, B), and the grouping of the head setae is also 

 quite different from that of the pink bollworm; A 1 , A 2 , A 3 , and V lie in 

 almost a straight line, and the puncture A a is well back of (almost directly 

 posterior to) A 2 rather than between it and A 1 as in Pectinophora gos- 

 sypiella. 



The larva is most like that of Eucosma helianthana, from which it 

 differs in the size of the head, the color of the thoracic shield, and the 

 position of epicranial puncture A a . In E. Jielianthana the puncture (A a ) 

 lies to the side directly dorsad of seta A 2 , between it and the adfrontal 

 suture, the head is smaller in the full-grown larva, and the thoracic 

 shield is brown with a more or less distinct hyaline kidney-shaped spot 

 on the side. In Laspeyresia tristrigana the shield is of the general body 

 color with a few small, irregular, scattered yellow spots. Neither species 

 has an anal fork. 



The pupa is similar to that of Crocidosema plebeiana. 



Several adults were reared during May, 191 9, from larvae collected in 

 August, 1 91 8 (Anahuac, Tex.) and in November, 19 18 (El Vista, Tex.). 



FAMILY PHALONIIDAE 



PHALONIA CEPHALANTHANA, N. SP. 



(PL. IOO, A) 



Phalonia cephalanthana, n. sp. 



Antennae grayish black, palpi dull yellow, whitish above and on inner sides. Face 

 whitish. Head yellow. Thorax mahogany-red. Fore wings brownish overlaid with 

 mahogany-red mixed with a few blackish scales, the red scaling unevenly distributed, 

 forming an obscure but distinguishable outwardly angulate basal patch, a broad, 

 vertical, somewhat irregular median fascia, and a moderately broad, outwardly 

 oblique costal dash near apex, the latter extending from apical fifth of costa to below 

 middle of termen; other areas of wing brown, more or less streaked with reddish or 

 black scales; cilia mixed brown, red, and black. Hind-wings smoky gray; under- 

 side faintly mottled; cilia grayish white. Legs heavily dusted on outer sides with 

 grayish black; ends of joints and inner sides yellowish white. In general appearance 

 to the naked eye the insect is a rather pale wine-red, blotched with darker shading of 

 the same color. Male genitalia of type figured (PI. 100, A). Alar expanse 8 to 10 mm.
