BAGWORM MOTHS OF THE WESTERN HEMISPHERE 8o 



Htjaloscoti's [sic] fumosa Gaede in Seitz, Macrolep. World, vol. 6, p. llSo, pi. lG9f, 

 1936. 



Male. — (Fig. 27.) Antennae with approximately 29 segments; 

 pectinations extremely long, slender. Foretibia with slender epiphy- 

 sis, nearly equalling tibia in length. 



Primaries R5 usually connate to base of R3+4, sometimes slightly 

 separate. Secondaries with M2 usually separate from M3, in one in- 

 stance observed connate. Wing expanse 26-30 mm. 



Male genitalia. — (Fig. 271.) Sacculus minutely toothed at apex. 

 Saccus broad at base, tapering gradually to tip. Eighth sternite 

 (fig. 209) with lateral margins nearly straight; furcations paralled to 

 slightly divergent. 



Female. — Unknown. 



Case. — Unknown, but may be represented by the larval case of 

 H. fragmentella. 



Type. — In the British Museum of Natural History. 



Type locality. — Mt. Shasta, California. 



Recorded hosts.^ — None. 



Distribution. — (Map 4.) This species is represented by only five 

 males, all of wliich Avere collected by Lord Walsingham in 1871 from 

 the Pacific Mountain System of northern California. One specimen, 

 the holotype, is labelled "Mt. Shasta"; the others, merel}^ "Siskiyou 

 Co." 



Discussion. — This insect differs from the following species in a 

 very fundamental character: the presence of an epiphysis, whicli, by 

 itself, as mentioned previously, cannot be considered the sole basis 

 for generic separation. Other, very similar features, such as genitalia, 

 scale structure, antennae, and general habitus provide ample reason 

 for maintaining these two species in a single genus. 



Dyar (1923) has synonymized H. fumosa under H. fragmentella 

 Henry Edwards (and its supposed synonym H. comferella. Henry 

 Edwards), giving H. fragmentella priority. This association prob- 

 ably will prove correct when the pertinent stages of all three are 

 better known and, in addition, the distribution of H. pithopoera is 

 more fully understood. The exact relationships cannot be stated 

 definitely at present as the known larval cases in this genus are in- 

 separable on a specific level. Thus, it is possible that some of the 

 cases currently identified as H. fragmentella and H. coniferella actually 

 pertain to H. j^ithopoera, which was described from Idaho. For 

 these reasons, H. fragmentella and H. coniferella are discussed sep- 

 arately (pp. 148-149, 152). 



The flight time of this species is probably in the interval from mid- to 

 late summer, which can be ascertained from Lord Walsingham's 

 itinerary in California and Oregon during the years 1871-1872 (Essig,
