1908] Catalogue of the Genus Alaptus 187 



funicle joint in eriococci is distinctly twice longer than wide; in iceryae it is not 

 more than one-third longer than wide, and sub-oval in shape, not cylindrical; 

 in iceryae, funicle joints 1 and 2 are subequal; also in eriococci. funicle joint 2 

 is at least sube:|ual to, or longer than, the third funicle joint, whereas in iceryae, 

 funicle joint 2 is distinctly shorter than funicle 3. 



Scape and pedicel normal, nearly as in eriococci; pedicel shorter and some- 

 what stouter, e lual to, or slightly longer than the combined length of the first 

 two funicle joints; funicle joints 1 and 2 abruptly smaller, subequal, funicle 

 joint 1 subquadrate, joint 2 cylindrical oval: the latter about one-fourth longer. 

 Funicle joints gradually enlarging to the club; funicle 3, elliptical oval, about 

 one-third longer than the preceding joint, and wider; joints 4 and 5 of the funicle 

 subequal in length to joint 3, each wider than the other, joint 4 regularly oval 

 and joint 5 roundish ovate; funicle joints 3, 4, and 5 widest at the apica! third, 

 and none are as long as the pedicel or as wide; club regularly ovate, more regu- 

 lar than in eriococci. Setae the same, the basal row on the 3 apical funicle 

 joints, however, apparently absent (high power), the apical row more distinct 

 than in eriococci. (From 3 specimens, 2-3 inch objective, Bausch & Lomb.) 



Male: — Length 0.091 mm.; wing expanse, excluding cilia, 1.45 mm.; 

 length of fore wing 0.58 mm.; width of fore wing 0.45 mm.; 



The same. Resembles very closely the male of eriococci, but is lighter in 

 color, and slightly larger. However, at once distinguished by antennal charac- 

 ters. The second joint of the fiinicle smallest, very slightly more than half the 

 length of the first funicle joint. This character is not present in the inales of 

 eriococci, and the less similar caecilii and minimus. 



Scape and pedicel the same, the latter subequal in length to the two fol- 

 lowing fiinicle joints combined; funicle joint 1 suboval, distinctly longer than 

 funicle 2, and shorter than funicle 3; funicle 2 .subquadrate, about a third of the 

 length of the next joint; funicle 3 thicker, ovate, nearly as long as the combined 

 length of the two preceding joints, but about one-third shorter than the next 

 joint, subequal in length to the pedicel; funicle joints 3-7 gradually widening 

 to club; funicles 4-7 subequal in length, longitudinally carinate, the three apical 

 joints with two distinct rows of setae at basal and apical third respectively, the 

 basal row less distinct on funicle 4; ftmicles 4-7 slightly more thick at their apical 

 third or fovirth, all about one-third longer than the club joint, and thicker. The 

 club or distal joint normal, conical, the base however rounded, and subequal 

 in length to the pedicel, or slightly longer, less distinctly carinated. The club 

 bears from 3 to 4 rows of sparse long setae, the three proximal funicle joints one 

 each distad (in the middle of the basal funicle joint) ; and funicles 3-7 acute at 

 their apico-lateral angles (high power). (From 7 specimens, 2-3 inch objective, 

 Bausch Sc Lomb.) 



Described from 7 males, and 3 females, mounted in balsam 



and received for study from Dr. L. O. Howard. These specimens 



were labelled as follows: "Bred from male pupa of Icerya pur- 



cliasi. (Coquillett.) ", 6 males, 3 females, bearing dates of May 



24, July 19 and 23, August 4, 17, 22 and 25, and October 4, 1887; 



and "Bred from Aspidiotus convexus, November 28, 1887", i 



male. The species was therefore reared by Mr. D. W. Coquillett 



in California from the male pupae of Icerya purchasi Maskell 



and from some stage of the Greedy Scale, Aspidiotus rapax Com- 



stock. The second species of the genus to be described from 



North America, Alaptus pallipes Ashmead being the first. 



Types: — No. 11938, U. S. National Museum, Washington, D. C, 



3 c?, I ? (the 4 slides originally labelled iceryae.) Cotype, 



Accession No. 37489, Illinois State Laboratory of Natural 



History, Urbana, Illinois, i male, i female (2 slides). 



This species was also overlooked by Dalla Torre (1898).
