along costa ; apices determinate ; outer margin a little rounded 

 and rather short, the inner margin being sub-parallel with costal 

 and in T. Dentatclla with a rounded, basal enlargement. The 

 insects have a resemblance to some HeterocampiB {Celtiphaga.) 



Trichopolia Dentatella. n. s. 



$. Very dark grayish fuscous with a greenish or olive cast. 

 Markings illegible ; the three stigmata indistinct ; moderate, sub- 

 equal, outlined in black. Terminal space with interrupted dashes. 

 Hind wings white, with terminal dotted line. Antennae bipecti- 

 nate. Thorax like fore wings, with a greenish cast, indistinctly 

 marked. Arizona. 



Trichopolia Ptilodonta. n. s. 



$ ? . Entirely dark grayish fuscous ; male antennae simple. 

 No greenish or olive cast whatever. The stigmata are concolor- 

 ous, outlined in black, reniform large ; claviform wide ; orbicular 

 with a central dot. Lines indistinct. Hind wings white ; soiled 

 in female, with dotted mesial line ; beneath with discal point. 

 Thorax like primaries. Two females ; one male. Arizona. J. 

 Doll. 



This looks like Dentatella, but differs by the want of any olive 

 tinge, the simple antennae of the male and the larger, better de- 

 fined stigmata. Roth, but especially Dentatella, look like small 

 Notodontidae. The hair}^ lashed eyes, the Notodontiform abdo- 

 men, the general shape of the wings, seem to unite the two 

 species, although the male antennae are very different. Before 

 examining the frenulum I took the three specimens of Ptilodonta 

 for females of Dentatella. If, as the plainly single frenulum of 

 one Ptilodonta assures me, I have made no mistake ; it is yet pos- 

 sible that a different genus must be used for the second species. 



LlTHOPHAis^E GaUSAPATA. n. S.. 



Allied to Petulca. Entirely of a dull purple red, the primaries 

 showing a gray bloom. Fore wings with the two mesial lines 

 brown, sub-parallel, outwardly oblique from costa, more or less 

 fragmentary and indistinct. Reniform a rusty yellow stain. 

 Claviform indicated-in pale, with a small brown following mark. 

 Hind wings and a^d^Tnen dull red ; beneath a brown discal dot 

 on secondaries. Frontal tuft a little darker beneath. Soda 

 Springs in October (Behrens). One bred specimen, the wings on 

 the left side a little unexpanded. The markings are simple and 

 the species readily detached ; it is much darker and more richly 

 colored than its eastern dW'xQS petulca, f err ealis, etc. 



Agrotis Perfusca, n. s. 



All the tibis spmore ; allind to Cochranii {messoria Harris 

 teste Riley), but uniformly dark fuscous leaving all markings 

 illegible. Smaller than Pastoralis. Stigmata concolorous, mod- 

 erate ; orbicular round ; reniform wide ; both marked by whitish 

 scales and similar scales dispersed along s. m. fold. Hind wings 

 fuscous. Abdomen flattened. Beneath paler ; hind wings with
