most one-third the length of the scape, longer than widq, subctmeate in shape, 

 wider than the scape and much more so than the following joint, about two- 

 thirds the width of the club, and slightly shorter than the combined length of the 

 lirst two ftmicle joints; funicle joint 1 the smallest joint, longer than wide, one- 

 third shorter than ftmicle joint 2; the latter cylindrical, twice longer than wide, 

 subequal to or slighth' longer than funicle joint 3 which is inclined to be a little 

 thicker and shorter; joints 4 and 5 of the funicle suboval, joint 4 one-third wider 

 than funicle 3, and one-third narrower than funicle 5, and about subequal in 

 length to funicle joints 2 and 3; the apical joint of the funicle more round, and 

 slightly shorter; club normal, not as long as the combined length of the four pre- 

 ceding joints, but longer than that of the three preceding joints; subequal in 

 length to the scape but twice wider, or nearly so. Setae on antennae as in 

 caecilii. (Fig. 4). (From 11 specimens, 2-3 inch objective, Bausch & Lomb.) 



Male; — Length, 0.620 mm.; wing expanse, excluding cilia, 1.44 mm.; width 

 of fore wings, 0.394 mm.; length of fore wings, 0.618 mm. 



The same, more slender. Antennae 10-jointed, filiform, longitudinally 

 striate, more finely so in the pedicel; dissimilar from those of caecilii and iceryae, 

 the shape of the segments more similar to the latter species; in eriococci the first 

 funicle joint is the shortest, about half the length of the pedicel, but in iceryae 

 the second funicle joint is distinctly the smallest, about, or slightly less, than 

 half of the pedicel, while in caecilii the first ftmicle joint is the smallest and 

 more than half the length of the pedicel. 



Scape and pedicel as in the female; first funicle joint globose, not two-thirds 

 the length of the following joint (funicle 2) which is cyhndrical, longer than wide 

 and subcuneate in shape; funicle joints 2 and 3 subequal; joints 4, 5, 6, and 7 

 subequal, wider and one-fourth longer than the joints 2 and 3, more hairy and 

 slightly more rounded ; apical or cltib joint pointed ovate, rounded at base and 

 tapering somewhat to tip from the middle, narrower than joints 4-7 of funicle 

 but subequal in length; joints 2-7 truncate apically, and widening very slightly 

 from the 4th joint, the apical angles acute. Setae as in the female; single rows 

 on joints 1 and 2 of funicle, on joint 3 a second row represented sometimes, and 

 on joints 4-7 two distinct row'S in the middle respectively of the proximal and 

 apical halves of the segments. (Fig. 5.) (From 25 specimens. 2-3 inch objec- 

 tive, Bausch & Lomb.) 



Fig. 5. Antenna of Alaptus eriococci, greatly enlarged. Male. 



Described from 25 males and 11 females mounted in balsam, 

 received for study from Dr. L. O. Howard, Chief of the National 

 Bureau of Entomology, and forming a part of their Collection of 

 Mymaridae. The specimens were labelled as follows: "Bred 

 from Rhizococcus araucariae. August 29, 30, 1887 (5 cJ*, 4?), 

 and September 1-5, 1887, (196", 7 ?) ", and "Bred from Aspidio- 

 tus aurantii (San Gabriel Valley) , Los Angeles, California, Sept. 

 9, 1887 (i(j)." Therefore reared from Eriococcus araucariae 

 Maskell and the Red Scale of California, Chrysomphalus aurantii 

 (Maskell). Habitat: Los Angeles, California.
