163. Tongue rudimentary, shorter than thorax, palpi massive and somewhat 



oblique ; wings obliquely streaked Ainolita. 



Tongue fairly strong, almost always functional 164. 



164. Palpi oblique, triangular, beak-like, vestiture of scales, venation inter- 



mediid Enstrotia ? albidnla and malaca. 



Palpi closely upturned to vertex 165. 



165. Thorax with slight but distinct anterior and posterior tufts; fore wing 



blunt, oblong, nearly as wide at basal fourth as at widest point ; 



trifid Monodes {Oligia). 



Thoracic tufts less distinct ; fore wing triangular, with marked apex, 



sillcy, dark with contrasting discal spot ; trifid Platysenta. 



Thorax with a slight posterior tuft or none, abdomen wholly untufted ; 



wings with rounded apex, somewhat variable in form ; t.p. line not 



straight; vestiture of spatulate scales 166. 



Thorax and abdomen untufted, clothed with simple scales, fore wing 



broad with marked apex, straight, white-streaked costa, and straight 



outer line; venation intermediid with fairly strong M,. . Oruza (70). 



166. Reniform a strongly contrasting white U or V. . Apamea ? u-album (71). 

 Reniform, a small white spot or not white Caradrina (72). 



167. Palpi upturned to well beyond vertex, the third joint half as long as 



the second or more, close-scaled ; the second joint also normally 

 smooth or only a little rough-scaled, either joint distinctly blade- 

 like only in species where the palpus only moderately exceeds the 

 vertex. Fore tibia of male only half to three-fifths length of femur 



and fitting into a notch in it, without special tufting 168. 



Palpi normally blade-like and porrect, if upturned, extending to nearly 

 twice height of head, and with strongly blade-like second and usually 

 third joints 169. 



168. Fore wing with marked apex and sinuous outer margin.. Phalccnostola. 

 Fore wing rounded Epizeuxis.

 Coloring dull 1 70. 



170. Males (frenulum simple) 171. 



Females (frenulum of three bristles) 179. 



171. Fore leg strongly modified, usually with a fan-like tuft on femur and one 



on tibia, tarsus reduced, except sometimes the first joint, and rising 

 near the base of the tibia which is hollowed out to receive its 



tuft 172. 



Fore leg normal. Hypenini 175, 



172. Antennae simply bipectinate Philometra. 



Antennre with a nodosity and tuft at about basal third, unipectinate before 



it and bipectinate beyond Hormisa. 



Antennae ciliate with a knot and spines near middle 173. 



Antennae simply strongly ciliate 174. 



173. Knot before middle of antenna, less conspicuous, palpi upturned with 



slender third joint Zanclognatha,
