AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAE 



157 



middle, bordered outwardly by a thin black line and 

 inwardly by a broad dark shade which includes the 

 black raised-scale ridge; a white blotch on lower half of 

 wing just beyond the antemedial line; subterminal line 

 well defined, median section broadly triangulate, bor- 

 dered inwardly by a blackish line and outwardly by a 

 narrow dark shade; discal marking a white spot covering 

 discocellular vein; a row of confluent black dots along 

 termen. Hind wing white with a faint ocherous tint; a 

 fuscous shade at apex and, narrowly, along termen. 

 Alar expanse, 23-30 mm. 



Male genitalia like those of zimmermani. Female 

 genitalia similar to those of cambiicola, differing only in 

 trifling details of the spining in the bursa, not exhibiting 

 any consistent differences of a specific character. 



Type locality: Colorado (tj^ie in AMNH, ex 

 Rutgers). 



Food plant : Cones of Pinus monophylla. This rec- 

 ord from reared Nevada specimens received from the 

 Forest Insect Division of the U. S. Bureau of Entomol- 

 ogy and Plant Quarantine under Hopkins U. S. No. 

 32009. 



Distribution: New Mexico, Jemez Mts. (Aug.), 

 Jemez Springs (Aug.) ; Arizona, Mohave County (July, 

 Aug.) ; Colorado; Utah, Dividend (Aug.), Eureka (Sept.), 

 Ibapah Mts. (Trout Creek, July) ; Nevada, Topaz Lake 



Another close relative of zimmermani and cambiicola, 

 distinguished chiefly by its much paler forewings. In 

 his original description Hulst gives Hot Springs, N. 

 Mex., as the type locality; but this, as pointed out by 

 Barnes and McDunnough (1918) is evidentally a lapsus. 

 The type is a male, labeled "Colo. Bruce."

list of the Lepidoptera of Boreal America, No. 5575, 1916. — 



McDunnough, Check list, No. 6139, 1939. 



Maxillary palpus of male squamous. 



Forewing with a subbasal scale ridge and small patch 

 of raised scales in median area; dark gray with a fine, 

 sparse, white dusting, making the general color a dark 

 ash gray; transverse lines whitish gray, distinct; ante- 

 medial line twice notched, edged outwardly by a thin 

 black line, preceded by an obscure pale patch on lower 

 half of wing, this followed on its inner margin by a black 

 scale ridge continued as a thin black line to costa; sub- 

 terminal lino outwardly angled at middle, bordered 

 inwardly by a black line and outwardly by a narrow 

 dark shade; discal spot white; a narrow black line along 

 termen. Hind wing white, smoky at apex and some- 

 what along termen (especially on females) ; the veins 

 more or less darkened ; a fine brown line along terminal 

 margin. Alar expanse, 21-27 mm. 



Genitalia similar to those of baumhojeri except for the 

 shape of the uncus. The latter has a more broadlj'^ 



roimded terminal margin on gulosella (compare figs. 

 391 and 392). 



Type locality: Hot Springs, N. Mex. (type in 

 AMNH, ex Rutgers). 



Food plant: Not definitely known, but undoubtedly 

 pine. 



Distribution: New Mexico, Hot Springs (Aug.); 

 Colorado, Glenwood Springs (July, Aug.), also one 

 female with only the state locality (Bruce, collector) 

 and bearing a Hulst "type" label. The type from New 

 Mexico is also a female. The Colorado specimens (2 

 c? and 4 9) are all in the National Collection. Thej'^ 

 are a perfect match for Ragonot's figure. 



322. Dioryctria baiimhoferi, new species 

 Figures 391, 881 



Maxillary palpus of male squamous. 



Forewing with raised scaling as on typical zimmer- 

 mani; blackish gray with the usual black marldngs indi- 

 cated by a more intense darkening of the ground color; 

 the transverse lines faint but distinguishable, gray; 

 antemedial line bordered inwardly by a broad black 

 band including the subbasal scale ridge; a similar 

 blackish, transverse shade across the middle of the 

 wing; subterminal line outwardly angulate at middle, 

 bordered inwardly by a black line and outwardly by a 

 rather broad black shade extended into streaks on some 

 of the veins; a black line along terminal margin; discal 

 spot whitish gray, sometimes very faint. Hind wing 

 smoky graj"^; the veins darkened and the smoky shade 

 intensified along termen. Alar expanse, 25-28 mm. 



Male genitalia having uncus triangulate with nar- 

 row^ly rounded apical margin. Female genitalia of the 

 zimmermani type but with ductus bursae shorter in 

 proportion to length of bursa and somewhat broader. 



Type locality: Prescott, Ariz, (type in USNM, 

 61355). 



Food plant: Pinus ponderosa. Larvae feeding in 

 new growth. 



Described from male type and one male and nine 

 female paratypes from the type locality, reared under 

 Hopkins Nos. 9932C and 18506, June 5, 6, and 11, 

 1928, by the late L. G. Baumhofer of the Forest Insect 

 Division of the U. S. Bureau of Entomology and Plant 

 Quarantine. Baumhofer's extensive rearings and field 

 studies, especially in the Nebraska National Forest, 

 have contributed what knowledge we have of the 

 biology of the Dioryctria species in that area. 



The new species is close to gulosella Hulst, from which 

 it is distinguished by the much darker color of its fore 

 and hind wings, differently shaped male uncus, and the 

 somewhat stouter spining of the male penis. It may 

 prove to be a local race of gulosella but is at least as 

 distinct from it as cambiicola is from zimmermani.
