DESCRIPTION OF AlAPTUS MINIMUS WALKER. 



Similar in general to the others. 



Female: Scape long, slender, and curved, longer than pedicel and funicle 

 1 combined. Pedicel conical, stout, the margins convexly curved, wider than 

 the scape, and thrice wider and nearly as long as the first funicle joint, its 

 cephalic margin truncate, apparently serrate, widest at the base of the apical 

 third and tapering proximad; the first three funicle joints slender cylindrical, 

 the first and third subequal, but the third a little stouter than the first and 

 second and a little longer than the first; the second one-fourth to one-third 

 longer, the longest funicle joint , long and narrow; funicle 4 cylindrical oval, 

 distinctly wider than 3 and shorter, subeciual to 1, but a little shorter; funicle 

 5, subcorneal, the shortest and stoutest funicle joint, widest at the apex, the 

 margins straight, a little over one-half the length of funicle joint 2, and shorter 

 than the pedicel; club, the largest antennal joint, ovate, not exceeding the 

 length of the 3 apical funicle joints combined, but twice wider than funicle joint 

 5. Setae as in the other species. (Fig. 1.) 



Fig. 1. Antenna of Alaptus minimus Walker, greatly enlarged. Female. 



Fore wings with two rows of discal cilia along the whole of the costal margin, 

 one of the rows sometimes obscured. Hind wings with a single long row of the 

 same, nearer the caudal margin. (From 2 specimens. 2-3 inch obj. Bausch & 

 Lomb.) 



Male — Same as female. 



Antennae filiform; scape shorter, not exceeding the length of the pedicel 

 and funicle 1; pedicel the same; funicle joints not so slender, cylindrical; 1 the 

 shortest, subequal to 7; 2 and 3 subequal, 2 longer, however; 1, 2 and 3 equal 

 in width; 4, 5, 6 and 7 gradually thickening, cylindrical oval, one-fourth to one- 

 third wider than the three proximal joints; 4, 5 and 6 subequal in length, 4 

 longer, however, subequal to 2; 2 and 4 the longest funicle joints; 7 one-fourth 

 shorter than 6; the club ovate, one-third shorter than 7, and sub-equal in length 

 to the pedicel; as thick as funicle 7. (From 2 specimens. 2-3 inch objective, 

 Bausch & Lomb.) 



Redescribed from 2 males and 2 females, beautifully mounted 

 in balsam by Mr. Frederick Enock of London, and comprising 

 specimens determined by an English authority and in the col- 

 lection of Dr. L. O. Howard, by whom they were loaned to the 

 author. 



The antennae of the male of minimus are very distinct from 

 those of the male of iceryae but somewhat similar to those of 

 caecilii, from which they differ in the fact that the funicle joint i 

 is not much shorter than funicle 7 and that 2 and 4 are distinctly 

 the longest funicle joints; from those of the male eriococci they 

 are very distinct, the funicle joints in the latter being much 

 shorter, the first three not long and slender, but all round oval, 

 conic, or ovate, and the apical joint is the longest funicle joint; 

 in eriococci and iceryae males, the shape of the antennal joints 

 are entirely different from those of minimus and caecilii.
