Leconte) but the hind tibiae are also affected. These are slightly bent, 

 the apical half of inner edge emarginate and the emargination filled with 

 a brush of fine hair. 



Malthodus parvulus. This, our smallest and at the same time com- 

 monest species of Maltholes acquires a special interest from the fact that 

 the male still remains entirely unknown. In our other species of Mal- 

 ihodcs the males are not rarer than the females, but of t\\'\s pusillus I have 

 myself, during the past three years, examined more than 200 specimens 

 without rinding among them a single specimen that could be considered 

 as the male. The specimens I saw in Dr. Leconte's collection marked 

 as males are undoubtedly females in which the last abdominal segment 

 became accidentally lengthened and somewhat distorted in the process of 

 drying 



Xylophilus fasciatus. Male: Anterior tibiae with the outer edge 

 strongly curved, inner edge strongly sinuate, almost angulate at middle. 

 Posterior femora clavate and suddenly widened a little beyond the mid- 

 dle; inner edge of hind tibiae with a row of fine hair and with a slight 

 dilation near the base, terminal spur long. 



Female: Anterior tibiae, posterior femora and tibiae simple, the latter 

 with the terminal spur short. Last antennal joint smaller in the male. 



Xylophilus piceus Hind femora in male armed near the tips with a 

 lar^e triangular tooth.

 Geometra rectaria Git. (Can. Ent. IX, 157, 1877.) 



This seems to be a good species, and is found in some abundance 

 in Central Texas and more rarely in Arizona and California. It is in 

 some respects intermediate between G. iridaria Guen. and G. illuslraria 

 Hulst and may yet be found to grade into both. 



Aplodes latiaria Pack. (5th Kept. Peab. Acad. p. 74, 1873.) 

 Prof. Lintner has kindly loaned me the type of this species for exam- 

 ination. I am unable to separate it from A. mimosaria (Guen, Phal. I, 

 p. 377, 1852) except as a varietal form. The only material point of 

 difference noted by Dr. Packard is that there is no inner white line on 

 the hind wings. But on the specimen marked by him as "Type", the 

 inner line is clearly indicated though very faint. In my observation there 

 is in specimens of A . mimosaria every gradation from the distinct inner 

 line to the form with the line obsolete. The name mav be retained as a
