52 The Ottawa Naturalist. 



Carneades INSULSA Walker, August 6 and ii; two 

 males. They are in bad condition, but show more red than 

 usual in the ground color. The species occurs throughout the 

 northern and mountainous regions of North America. 



Carneades tessellata Harris, August 2; one male, one 

 female. They are somewhat different from the usual eastern 

 type, but are unfortunately too poor to serve for purposes of 

 critical comparison. The species occurs throughout North 

 America north of Mexico. 



Carneades redimicula Mom, August 20; two males, 

 offering nothing unusual. The species is here at the most north- 

 western limit recorded. 



Mamestra purpurissata, G. & R., August 20; two males 

 in such condition that determination was barely possible. This 

 is the most north-western limit thus far recorded. 



Hadena lateritia Hfn., July 21 (i); July 27 (i); August 

 25 (i). The late specimen is a female; but none offer anything 

 worthy of special remark. The species has not yet been recorded 

 from any point west of the Rocky Mountains. 



Hadena IMPULSA Mom, July 21 ; one specimen of usaal 

 type. This is a typical northern and eastern species, but also 

 occurs, rarely, in Texas. 



Hadena devastatrix Brace, July 18 and 21 : two male 

 specimens. The examples are unusually well marked and the 

 black ornamentation is so contrasting as to obscure the recog- 

 nition of the species at first sight. Occurs throughout North 

 America. 



Orthosia CONRADI Grote, August 4 (i); August 5 (i) ; 

 August 14 (i) ; August 17 (i) ; August 20 (i) ; four males and 

 one female. I am not quite certain of this determination, be- 

 cause the species of this genus have not yet been satisfactorily 

 studied. They do not seem to be congeneric, and I suspect that 

 one species figures both as a Xylo2:)hasia and as an Orthosia. 

 Of the specimens before me no two are quite alike, and the 

 female is of a much brighter red-brown than any other specimen
