dor.sall}^, whitish siibventrally find on feet, lateral wai'ts pale. A yel-

 Hairs whitish, mostly thin but tufted in dorsal fans, black on joint 5, 

 white on (> and 5 laterally and slighth^ on 4; a l)lack subdorsal pencil 

 on 12 and small white tuft below it. Joint 12 somewhat enlarged. 

 Later the subdorsal stripe and subventral ])and are more or less dark 

 red. One had the tufts on joint 5 brown, those of i and 6 pinkish 

 ocherous. 



Stage VI. — Head black, paraclypeus, epistoma, edges of labrum 

 white; width 3.2 mm. Subdorsal stripe on joints 10 and 11 at tubercle 

 ii and subventral band at tubercle v deep red shaded. Body l)lack 

 dorsally, dotted and streaked with white on the sides. Fan tufts on 

 3, 4, and (> creamy white, that on 5 larger and pale brown; divaricate 

 pencils of joint 12 black with white ones below. Other hair mostly

MEROLONCHE LUPINI Grote. 



No specimens. One in Mr. Cockle's collection is labeled splnea 

 Grote and seems intermediate between that and lapinl, for the ordi-

 and angulated in the middle. 



PANTHEA PORTLANDIA Grote. 



No specimens; one from Mr. Cockle's collection is before me. 



PANTHEA GIGANTEA French. 



No specimens. One from Mr. Cockle's collection, collected August 

 13, 1902, is a female and expands only 45 mm. 



RAPHIA PRATER Grote. 



No specimens; one from Mr. Cockle's collection, June 2, 1!»()2. The 

 form is similar to that which I have from Easton, Washington (Koe- 

 bele). Like Gluj)h!.sla spetentrkmalh., discussed later, this species 

 feeds on the aspen and cottonwood, and its range is coextensive with 

 its food plants. As with the GlupMsia., Rapliia runs to a variet}^ of 

 local forms, exactly paralleling the forms of Ghrpltlsla and conditioned 

 b}^ the same differences in environment. Prof. J. B. Smith has lately 

 conceived the idea of treating all these forms as distinct species, exactly 

 as the late Henry Edwards did with Glupldsia twenty j^ears ago. But
