A NEW PHYCITID INJURIOUS TO PINE 



{Lepidoptera, P^ralida) 

 By HARRISON G. DYAR 



Pinipestis erythropasa, new species. 



Fore wing with basal area broadly red-brown, smooth ; inner line 

 whitish, angled or irregular centrally, widest at costa and a little oblique 

 outwardly below ; median space, especially the area following the inner 

 line, grayish white, with raised scales, not forming a distinct ridge ; a red- 

 brown band across median space, containing the quadrangulsir, upright, 

 white discal spot in its outer edge ; outer line whitish, in-angled subcos- 

 tally, slightly denticulate, preceded by a red-brown line and followed by 

 red-brown nearly to the margin ; terminal line dark red-brown ; fringe 

 red-brown. Hind wing shaded with fuscous except between the veins ; 

 a double, dark terminal line ; fringe with a little red-brown. Expanse, 

 male, 21-24 mm.; famale, 25 mm. 



Cotypes, two males and two females. No. 18315, U. S. Nat. Mus. ; 

 bred from cones of Pinus chihuahuana, Chiricahua National Forest, 

 Arizona (A. W. Zachau). 



This species may be found to be more properly referable to the genus 

 Dioryctria. This differs from Pinipestis only in the absence of the scale- 

 ridge of fore wing. The ridge is not very apparent in the specimens, 

 but they have all suffered some abrasion, and I thought the ridge might 

 be apparent in fresh specimens.
