Acrolophus occidens, new species. 



Male. Labial palpi curved, ascending, reaching vertex; first joint as 

 long as second and third together, with evenly rounded brush ; second 

 joint also with a brush, continued slightly up over the equally long, 

 smooth third joint. The form of the palpi is intermediate between 

 those described for the genera Enlepiste and Neolophus Walsingham. 

 The scales of palpi, head, and thorax are brownish fuscous, tipped with 

 white. Antenna? ochreous fuscous. Fore wings grayish ochreous, 

 overlaid with black, brown, and white scales. There is an oblique, 

 ill-defined dark shade, edged with white, from apical fourth of costa 

 to the middle of dorsum, nearly parallel with the terminal edge ; on 

 the apical fourth of the wing are four or five small black dots and 

 Miitside of these the wing is strongly overlaid with white scales. Hind 

 wings dark fuscous ; abdomen dark fuscous, with white bands on the 

 upper side. Legs ochreous, mottled with fuscous and with indistinct 

 black tarsal annulations. 



Alar expanse, 22 mm. 



Habitat San Diego, California. May. L. E. Ricksecker. 

 coll. Additional specimens are in the collection of Mr. Kear- 

 fott. 



Type No. 12694, U. S. National Museum. 



This species is very close in size, pattern, and form of the 

 palpi to Acrolophus (Enlcpistc] kearfotti Dyar, but is much 

 paler, lacks the costal black spots, and has the clear cut oblique 

 dash of kearfotti replaced by the less defined oblique fascia ; 

 the abundant white dusting, especially on the apical part, is 

 also lacking in Dr. Dyar's species. All these color differences 

 might, however, be individual in this group, where the color 

 and markings are quite variable, but the claspers of the male 

 genitalia are very different and the two species are undoubtedly 

 amply distinct. 



I am unable to retain as distinct the several genera erected 

 on the secondary sexual characters of the various forms of 

 palpi in this group. This view is shared by Lord Walsingham 

 and Mr. Durrant, and will be further elaborated in their forth- 

 coming part of Dr. Godman's Biologia Centrali- Americana. 



Acrolophus leopardus, new species. 



Labial palpi of the same form as in the preceding species ; ochreous 

 white, mottled with fuscous, especially exteriorly. Antenna 1 light 

 fuscous. Face and head white. Thorax ochreous white, sprinkled 

 ,,ith fuscous. Patagina fuscous. Fore wings ochreous white, dotted 

 svitb small blackish brown spots in rather regular transverse n>\w 

 Across the outer end of the cell is an interrupted, poorly defined
