NORTH AMERICAN ACROLOPHIDAE — HASBROUCK 499 



Characters of the Family and Genus 



The genus, Acrolophus, based upon a single Cuban specimen, was 

 described in Professor Felipe Poey's "Centurie de lepidopteres de 

 rile de Cuba." Written in French and Latin, it contains 20 colored 

 plates and is quite rare in library collections. Although the section 

 on Acrolophus is dated "Jul}^ 1832," the actual date of publication of 

 the entire work in Paris was probably sometime in 1833. 



The plate accompanying Poey's description of Acrolophus and A. 

 vitellus contains three figures: the first, an enlargement of the right 

 forewing of the male, is denuded to show a type of neuration in which 

 the "apical vein" is not forked; the second figure, representing 

 in natiu-al size the adult male in dorsal aspect, shows the overall 

 expanse of the wings to be about 20 mm.; the third, an enlargement 

 of the head, thorax, and legs of the male in right lateral aspect, 

 illustrates the elongated and recurved labial palpi. 



It should be noted that in his lexicon. Woods (1944) defines the 

 word Acrolophus as "a mountain ridge," a considerably different mean- 

 ing than that given to it by Poey. Poey's description, translated 

 from the French and Latin text, is as follows: 



Acrolophus vitellus, Poey 

 Char.\cters of the Genus 



[Latin] No tongue, antennae simple; palpi very long, recurved, extending past 

 thetergum; all segments barbed up to the apex; anal fringes long. 



[French] Genus Acrolophus, Poey. — Lacking a distinct tongue, antennae simple, 

 palpi very long, lying on the back, with all the segments barbed up to the ex- 

 tremity; long fringe toward the anal angle. 



Characters of the Species 



[Latin] Wing luteo-fuscous, forewing with small black spots, costa punctated 

 with black. 



[Remainder of article from the French] Acrolophus vitellus. — Wings of a yellow 

 brown; the forewings covered with small black spots, more distinct on the costa. 



Description 



See, on the adjoining plate, the male natural size, the same with the large palpi 

 and legs; and a forewing denuded of its scales, in order to show all the veins; the 

 examination of the discoidal cell shows us that there is still a lot to learn in the 

 study of this character, especially in the smallest species. The latter has the pro- 

 thorax tomentose and the head placed very low toward the breast. The underside 

 is entirely brown. 



Observations 



On the genus. — The Greek word axp6Xo</)os signifies that which carries a plume 

 to the extremity; I have made use of it in order to show that the palpi are covered 

 with elongated scales up to the extremity; it is in this that they differ from those
