8. All fimifle joints siibeqiial and concolorous 9 



Funiole joint 1 nearly as long as 2 and :t together : the latter subequal and 



white; joint 1 and the club blaek (Jittsiiidis, new species. 



0. Terminal joint of club shorter than basal joint aoiiidiic Howard. 



Club joints equal in length coquUlettii Howard. 



10. First funicle joint distinctl,v shorter than second tuicnsenxli. new species. 



Encarsia diaspidis, new species. 



Female. — Length l.C) mm.; expanse 3.0 mm.; greatest width of 

 fore wing O.o mm. Eyes markedly hairy. Antennal scape robust; 

 pedicel somewhat longer than broad; 1st funicle joint twice as long 

 as pedicel; joints 2 and- 8 much shorter and subequal in length and 

 width; club rather slender and pointed, longer than funicle joints 2 

 and 3 together; all joints, including scape, ])lainly hairy. General 

 color orange-yellow; antenna^ l)lack, joints 2 and 3 of funicle white; 

 eyes reddish; dorsum of abdomen and metanotum infuscated, except 

 for tip of abdomen, which is yellow; all legs uniform honey-yellow; 

 wing veins yellowish. 



Male. — The male Encarsia has not been described; but I have a 

 slide from Lounsbury containing male specimens reared from the 

 same host, in the same locality, and at the same time as the female 

 described above, and these are probably the males of E. diaspidis. 

 They are described as follows, generic characters included : Length 

 1.08 mm. ; expanse 2.4 mm. ; greatest width of fore wing 0.44 mm. 

 Antennse 8-jointed ; scape not long, slightly swollen in middle ; pedi- 

 cel short, only as long as broad; 1st funicle joint long, 6 times as 

 long as broad ; funicle joints 2 and 3 subequal in length and width 

 and each about one-half as long as joint 1 ; club 3-jointed, the seg- 

 ments as distinct as those of funicle ; club joints 1 and 2 about equal 

 in length to funicle joints 2 and 3 ; terminal joints shorter and rather 

 obtusely pointed at tip; all flagellar joints strongly longitudinally 

 striate. First joint of middle tarsus longest ; middle tibial spur 

 about as long as first tarsal joint. General color very dark brown, 

 nearly black; antenna^ uniformly dark brown; femora brown, hind 

 femora darker than front and middle femora ; trochanters light yel- 

 low; all tibiae dusky, lighter at tips; tarsi yellowish, with their ter- 

 minal joints brown. 



Type. — No. 10300, U. S. National Museum, Described from G 

 female and 6 male sj^ecimens, reared July, 1897, from a Diaspis on 

 Acacia horrida at Bathurst, Cape Colony, South Africa, by C. P. 

 Lounsbury. 



This species is probably not a true Encarsia. 



Encarsia portoricensis, new species. 



Female. — Length 1 mm.; expanse 1.84 mm.; greatest width of 

 fore wings 0.28 mm. Antenna^ rather stout, with flagellum uniformly 

 hairy, longitudinal striation only faintly discernible; scape uni-
