692 BULLETIN UNITED STATES GEOLOGICAL SURVEY. 



The localities are Texas, Long Island (N. Y.), Montreal, Massachu- 

 setts. It is uncertain that they belong here. 



In addition, Belfrage has collected in Bosque County, Texas, a num- 

 ber of specimens which agree closely in ornamentation, but are sepa- 

 rable into distinct forms by their differing size. Under the circumstance 

 that I am yet without positive identification of certain described species, 

 these forms should not be described at the present writing. 



In my opinion, the variability of the species of this genus will be found 



so great as to prevent accurate determinations until very large material 



is accumulated. 



PHYCIDJE. 



Ocelli sometimes wanting. Male antennse often with a peculiar 

 structure of the basal portion. This is sometimes bent, with a scale- 

 tuft [Nepliopteryx^ Pempelia) or without a scale-tuft (Anerastia), or, again, 

 slightly bent, somewhat rigidly held, with a succession of small over- 

 lapping scale-tufts {Pinipestis); again, there is a basal constriction 

 {Homeosoma) ; again, these peculiarities are wanting [Ephestia). The 

 maxillary palpi in the male are sometimes furnished with a concealed 

 pencil of hair [Pempelia, Salebria) ; again, they are small, scaled, and sim- 

 ilar in the sexes {NepJiopteryx, etc.) ; again, they are wanting. Tongue 

 scaled at base. Labial palpi similar in both sexes, scaled, ascend- 

 ing. Fore wings usually narrow ; hind wings broad, exceeded by the 

 slender abdomen. The clypeus is full, rounded. Eyes naked. Fore 

 wings 11-, 10-, or 9- veined ; vein 1 not furcate 5 8 out of 7 [Nephopteryx, 

 etc.), or these two veins fall together {Homeosoma). Generic characters 

 are offered by the differing position of 4 and 5, which have sometimes 

 separate origin, and again are furcate. The hind wings are 8-, 7-, or 

 6-veined, the three internal veins counting as one. Generic characters 

 are offered by the differing position of veins 4 and 5, veins 7 and 8, and 

 .the point of origin of vein 2. The female frenulum seems to be simple. 

 I do not find this character mentioned by authors, and it may not prove 

 invariable. 



The larvse live in fruit, under bark, or in cases on the leaves. Many 

 pupate on or in the ground ; others, like Pinipestis, in the thickened sap 

 or under the bark of the tree. Among this group are some of the most 

 dangerous foes to timber. In Europe, the pines are attacked by Diorye- 

 tria abietella and splendidella ; in the United States, the ravages of Pini- 

 pestis zimmermam on the same genus of trees have been noticed in many 

 places, and I have accounts of what I suppose to be injuries inflicted to 

 pineries by P. ? ahietivorella from two or three correspondents in New 



England. 



ACKOBASis Zeller. 



The male antennce have a pointed scale-tuft on the basal joint. In mbri- 

 fasciella, the male antennee are bent above the tuft, ciliate beneath. 

 Maxillary palpi small ; labial palpi pointed, curved upward. Fore wings
