AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAE 



153 



Type locality: Tryon, N. C. (type in USNM). 



Food plants: Pinus spp. Larvae feeding in the 

 cones. 



Distribution: Massachusetts, Martha's Vineyard 

 (June) ; New Jersey, Lakehurst (July) ; District of Colum- 

 bia; West Virginia, Roosevelt (June), North Carolina, 

 Raleigh (June), Tryon (June); Iowa, Ames (June). 



Examples of this species have been in the National 

 Collection as auranticella and it was on the basis of this 

 misapplication of Grote's name that Dyar described his 

 xanthaenobares. The true auranticella is strictly a 

 western species, while the distribution of disclusa, as 

 far as I know, is limited to the eastern and central areas 

 of the United States. 



The paper by Farrier and Tauber gives aU the infor- 

 mation known on the life history, food habits, and 

 behavior of the insect.

MaxiUary palpus of the male in the form of an 

 aigrette. 



Forewing smooth; color and markings similar to those 

 of disclusa, but on the average somewhat paler, the 

 ground color ranging from yellowish orange to brownish 

 red; on the darker suffused, reddish examples the yel- 

 lowish color of the basal area is less contrasted than in 

 ordinary disclusa. Very pale examples of the two 

 species cannot be distinguished superficially. In size 

 auranticella averages larger. Alar expanse, 27-33 mm. 



Male genitalia with apex of cucullus of harpe extend- 

 ing beyond apex of the sclerotized costa. Female 

 genitaha exhibiting only slight and comparative differ- 

 ences from those of disclusa. 



Type localities: New Mexico {auranticella, in Univ. 

 Kansas); Arizona (miniatella, in Paris Mus.); Kaslo, 

 British Columbia {xanthaenobares, in USNM) . 



Food plants: Pinus spp. Larvae feed chiefly in the 

 cones, sometimes in the twigs. The favored host seems 

 to be Pinus ponderosa. 



Distribution: United States: New Mexico, state 

 locality only; Arizona, Mohave County (July); Colo- 

 rado, Glenwood Springs (Aug.), Rocky Mountain Na- 

 tional Park (July); Utah, Eureka (July, Aug.); Idaho, 

 Coeur d'Alene (July); Montana, Bitterroot River 

 (July), Camas (July); California, Gasquets (May), 

 Pasadena, Warner Mts. (July); Oregon, Monumental 

 Pass (Aug.), Silver Lake (Aug.); Washington, Pullman

Halsey (Aug.), Valentine (July, Aug.). Canada: 

 British Columbia; Kaslo (Aug.), Trout Creek (Ibapah 

 Mts.). The Nebraska records, our most easterly, are 

 from examples reared from Pinus ponderosa in refor- 

 ested areas. The insect was probably introduced there 

 on western nursery stock. 



The species is represented by a large series of speci- 

 mens in the National Collection, a majority of them 

 reared from cones in connection with the forest insect 

 investigations of the U. S. Bureau of Entomology and 

 Plant Quarantine. The type of auranticella in the Snow 

 Collection at the University of Kansas is a pale femalr 

 in rather poor condition. Three other similar females, 

 in better condition are in the Rutger's College Collec- 

 tion. All of these are labeled simply "New Mexico, 

 Snow, Coll." Females of auranticella are not separable 

 from those of disclusa, especially the pale, yellowish 

 examples, except by their locality labels. On average 

 specimens the white streak along the lower margin of 

 the cell of forewing is shorter in auranticella, not reach- 

 ing beyond the outer angle of the cell; but this feature is 

 not constant in either species. Between males there 

 is never any need for confusion; for auranticella is the 

 only known American species with aigrettelike maxillary 

 palpi. 



A similar maxillary palpus occurs in Dioryctria laurata 

 (Heinrich) from Japan (described as a Salebria in Proc. 

 Ent. Soc. Washington, vol. 30, p. 61, 1928). The unique 

 male type has the labial palpi erect and appressed 

 close to the face and a strong scale tuft in the sinus of 

 the antennal shaft. Hence the original reference to 

 Salebria. It is probably a snyonym of Dioryctria 

 pryeri Ragonot (Monograph, pt. 1, p. 194, 1923), 

 described from a single female from the Holland Col- 

 lection, now in the Carnegie Museum, Pittsburgh. I 

 have never seen this specimen.

Maxillary palpus of male squamous. 



Forewing with some roughened (raised) scale tufts in 

 median area (one in lower fold and another in cell just 

 beyond antemedial line and a slight roughening of the 

 white scales of the discal spot), otherwise smooth; 

 ground color red-brown of a somewhat darker, more 

 rosy shade and lacking any of the orange suffusion com- 

 mon to auranticella and disclusa; more or less dusted 

 with white in median area, the white concentrated into 

 a broad patch extending from inner margin to top of cell 

 just beyond antemedial hne; the transverse lines thin, 

 white; antemedial line obHque, irregularly and very 

 weakly dentate; sub terminal line nearly vertical, slightly 

 denticulate, bordered inwardly by a dark red-brown 

 line; a similar dark line forms an outer border to the 

 antemedial line; discal spot a sUghtly enlarged, lunate,
