without parapsidal sutures ; mesoscutellum distinctly separated. Wings present. 

 Submarginal vein reaching nearly to costa ; marginal and postmarginal both exceed- 

 ingly short; stigmal long, slender. Abdomen sbort, oval; first and second joints 

 short, abdomen broadening rapidly from first joint; third joint very large ; fourth 

 and fifth visible. 



It agrees with the points mentioned in the very insufficient characterization of 

 Foerster's genus Aeolus, except that it is winged. Foerster, however, knew only the 

 female, and only mentions the fact that the antennal club is not jointed, and that 

 the scutellum is developed, while the wings aie absent or rudimentary. 



Acoloides saitidis, n. sp. 



Female. — Length, 1.4 mm ; expanse, 3. 6 mm ; greatest width of fore- wing, 0.46 mm . An- 

 tennae short ; pedicel long, nearly one-half the length of scape ; joint 1 of funicle 

 one-half as long as pedicel ; joints 2, 3, and 4 very short ; club very large, oval, and 

 one-third longer than four preceding joints together, but not quite as long as these 

 joints and pedicel together; no articulations can be distinguished, but it ishomologi- 

 cally composed of six joints. Eyes hairy ; lateral ocelli touching the eye margin. 

 Head, face, and mesonotum densely and finely punctate ; parapsidal furrows not 

 present; first and second abdominal segments with fine, close, longitudinal striae, 

 wanting at smooth posterior border ; the very large third segment and short fourth 

 densely and finely punctate, and clothed irregularly with short, whitish pile, which 

 is also present, although sparser, upon the mesonotum, and is quite thick on the ver- 

 tex; mesopleura finely punctate below ; metapleura smooth. The marginal vein is 

 very short and not quite coincident with costa; the post marginal is extremely 

 short; the stigmal is long and slender and terminated by a small rounded knob. 

 General color, deep black : all legs and antennae honey yellow ; all coxae black, 

 lighter at tips; scape brownish and pedicel darker than club. 



Male. — Differs from female only in antennae which are plainly 12-jointed; joint 1 

 of funicle as long as pedicel, joints 2 to 7 subequal in length and width, and each as 

 broad as long and well separated; club oval, nearly as long as three preceding joints 

 together. Antennae uniformly honey yellow. 



Described from 9 male, and 1 female specimens. 



Genus B-SJUS. 



Minute wingless Scelioninw, without differentiated scutellum and with non-jointed 

 antennal club. 



Beeus americanus n. sp. 



Female. — Length 0.65 mm . Length of antennal 

 club .185 mm , or in other words the entire body is 

 only three and one-half times as long as the au- 

 tennal club. Width of antennal club .082 mm . 

 General color dark honey-yellow ; scape and fun- 

 icle of antennae brownish, club lighter, dark at 

 tip; vertex and face light honey-yellow; dorsum 

 of thorax and abdomen dark honey-yellow, almost 

 approaching mahogany ; legs throughout concolor- 

 ous with head ; middle and hind tibiae a little 

 darker near base. Surface of abdomen smooth, 

 shiny ; mesonotum very faintly punctate. Thorax 

 and abdomen with extremely fine, sparse, whitish 

 pile ; tip of abdomen with a short and contracted 

 fringe of white pile. Antennal club very large, 

 longer than rest of funicle and pedicel together ; 

 funicle joints very narrow and short, subequal, 

 pedicel wider and as long as entire funicle except club.
