554 William T. M. Forbes 



claviform large, darker, but rarely contrasting, outlined with black; orbicular 

 and claviform horizontally oval and often slightly separated; postmedial finely 

 dentate when distinct; subterminal space finely strigose, with two streaks to an 

 interspace. Hind wing contrasting, pale luteous at base. 28 mm. 



June to October. 



The narrow wings and dull coloring make this species look like a Phycid. It 

 is one of the commonest Pyralids. The larva is a general feeder on low plants, 

 and has been reported definitely from Polygonum. It is yellowish green, with 

 darker tubercles. 



Distribution world-wide. New York: common everywhere. 



37. POLYGRAMMODES Guenee 



Wings ample, the fore wing less than twice as long as wide, with strongly 

 curved outer margin, stumpy looking. Wings translucent; R 5 strongly curved up 

 and approximate to R 3+4 ; hind wing with a black scale tuft at base of Cu, as 

 in Samea. Body stout, showing a strong tendency to grease; palpi as in 

 Stenophyes. 



1. P. capitalis Grote. White with some violet iridescence; with white fringe. 

 Fore wing overlaid with brown wool at base and inner margin. A fine, incom- 

 plete, black, antemedial line, a rather irregular postmedial; basal line sometimes 

 visible; orbicular a small ring; reniform a double black bar with a blackish patch 

 below it; a blackish patch at apex. Hind wing similar. 37 mm. 



June. 



Mississippi Valley. 



Variety posticata Grote and Robinson is practically immaculate, with yellowish 

 fore wing and white hind wing. The typical P. hirtalis Guenee, from Texas and 

 south, is much smaller. The names have sometimes been interchanged in collec- 

 tions, but I think the present use is correct. 



38. PACHYZANCLA Meyrick 



Structure much as in Nomophila and neighboring genera. Palpi rather smooth- 

 scaled, somewhat beaklike, with third segment very small, on upper side of second. 

 Fore wing triangular, twice as long as wide; M 2 concave up at base, and closely 

 approximate to M 3 . (I very much doubt u this genus is either natural or in the 

 right place here.) 



1. P. perfusalis Walker. Fore tibia with a terminal tuft. Inner margin of hind 

 wing distorted; anal angle lobed in male, with a short, stiff tuft, and an area of 

 black raised scales above Cu 2 , which is distant from Cu\ at margin. Dark fus- 

 cous, antemedial line darker, excurved; postmedial running in a broad sweep 

 from costa, far out toward outer margin, then in below cell to opposite reni- 

 form, then nearly erect to inner margin. A blackish discal bar. Hind wing duller, 

 with a slight postmedial line only. 22 mm. 



Larva on eggplant. 



Southern States; not seen from our area. 



2. P. bipunctalis Fabricius. No secondary sexual characters. Ground color 

 dull luteous, darkening on costa and outer margin, and on apical half of outer 

 margin of hind wing; with a short thick solid black reniform spot hardly higher 

 than wide, and smaller round orbicular dot. Subterminal line absent, and post- 

 medial indented opposite the cell. 25 mm. 



Larva (southern beet webworm) on beet and a great variety of other her- 

 baceous plants; injurious in the Gulf Strip. 



Decatur, Illinois, and south. The eastern records, so far as traced, are in 

 error for species of Phlyctsenia and Pyrausta, especially Piirausta nertextalia. 



I believe this sDecies would £o better in Sylepta.
