genera Acroloplius and Anaphora. 151 



" Smaller than A. plwmifrontella, and easily recognised 

 by its pallid discolorous fore wings, which are also a 

 little more determinate at apices and internal angle 

 than usual." 



I am not absolutely certain about the identity of this 

 species ; the only specimen I have seen with that name 

 attached was in a box sent to me for examination by 

 Prof" Fernald. I understood it had been obtained from 

 Miss Murtfeldt, but was very doubtful at the time 

 whether it was truly Grote's mortipennellus. The 

 memorandum I have about it shows that the apical 

 vein was forked, which would probably throw it into the 

 genus Neohiplius, but its colouring differed considerably 

 from the two species of that genus now described. In 

 Mr. Grote's collection in the British Museum are several 

 specimens with antennas simple and apical vein not 

 forked, which agree with the description, but are not 

 labelled. These have the uncus double, not sharpened 

 at the points, which slightly diverge ; the lateral claspers 

 long and slender, of almost even width beyond their 

 narrow stem, and evenly rounded at the ends. I have 

 little doubt that they represent the true A. mortipen- 

 nellus, Grote. 



Acroloplius cerrinus, n. s. (PI. VII., fig. 6). 

 Palpi, J, porrect, about 5 rum. long; whitish fawn-colour. 

 Head and thorax the same. Antenna, ? , simple. Fore wings 

 pale fawn-colour, the apex obtuse, apical margin oblique, costal 

 margin straight and nearly parallel with the dorsal margin 

 throughout ; a few dark fuscous scales are sparsely sprinkled about 

 the apical margin of the fore wings. Abdomen and legs of same 

 colour as kind wings. Exp. al. 34 mm. 



Two females collected by Belfrage in Texas on the 

 16th and 18th May (about 1868) respectively. I have 

 not seen the male of this species, but, although probably 

 closely allied to plumifrontellus, the narrow fore wings 

 with straight costa and almost straight oblique apical 

 margin show it to be distinct from that species. 



Acrolopkus argentinus, n. s. (PI. VII., fig. 8). 



Palpi, $ , recurved and reaching beyond the middle of the thorax. 

 Antennae greyish ochreous, serrated. Head, thorax, and -palpi 

 dull greyish fuscous. Forr wings greyish fuscous, slightly mottled
