THE CANADIAN ENTOMOLOGIST. 229 



North America is already credited with pecuHar genera, with few species, 

 clustering about the two principal genera, which are here :• Nonagria and 

 Heliophila. 



Tribe Scolecampini. 



The body is slender, smoothly haired ; the legs unarmed, thinly scaled, 

 rather long ; the wings vary from rather broad to quite narrow ; the colors 

 are mainly of the preceding group, and the caterpillar of Scolecocampa is 

 said to burrow in wood. This tribe, with the Arzamini, is exclusively 

 American, and may be considered, equally with that, to be an outgrowth 

 of the Nonagrians. I refer here (see Can. Ent. XV., 131) the genera 

 Scolecocampa, Eucalyptera, Amolita, Cilia, Doi-yodes, Phiprosopus. 

 Geyer's figure of 6*. liburna has the primaries shaded with red, a feature 

 I have noticed in fresh Southern examples of the moth. Mr. Morrison 

 seems to have had no notion of the affinities of his Eucalyptera bipuncta ; 

 1 referred the moth to Scolecocampa, the differences seeming only com- 

 parative, or of specific value. Since then I found a second Western form, 

 and, although the differences are not very decided, I adopt the genus. In 

 this tribe the ornamentation seems a modification of the usual Heliophilid 

 type. The longitudinal medium stripe, the pale oblique shade to the still 

 pointed primaries, the dots and dotted stigmata, varying in expression in 

 the diiferent genera, are Heliophilid features ; while the oblique and longer 

 palpi, often smoky on the sides, the slender feet and linean body dis- 

 tinguish the tribe. Doryedes is described as a Geometrid by Guenee, 

 and Phiprosopus (printed Phyprosopiis, originally in error) is described, 

 under characteristics which do not belong to the genus and were accidental 

 in the type, equally as a Geometrid by Zeller, who subsequently acknow- 

 ledged my prior and more correct reference of P. callitrichoides to the 

 Noctuidce. The chiloform appearance of most of the genera becomes 

 almost lost in Phiprosopus, notwithstanding the narrow wings, while the 

 labial palpi depart from the usual form ; these latter, and the peculiar 

 color, remind one of certain exotic genera allied to Calpe, where I was 

 at first disposed to locate the genus. When the immature stages are 

 known, our present views may be modified. Always must our classifica- 

 tions be judged by their reasonableness in reference to the existing 

 knowledge of the whole history of the insects.
