■without parapsidal sutures ; niesoscutellum distinctly separated. Wings present. 

 Submargiual vein reacliing nearly to costa ; marginal and postmarginal both exceed- 

 in"-ly short; stigmal long, slender. Abdomen short, oval; tirst 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. P^erster, however, knew only the 

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

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



Acoloides saitidis, n. sp. 



Female. — Length, 1.4"""; expanse, 3.6™"'; greatest width of fore- wing, 0.46'"'". An- 

 tenuie short ; pedicel long, uearlj^ one-half the length of scape ; joint 1 of fuulcle 

 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 strife, 

 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 i^unctate below ; metapleura smooth. The marginal vein is 

 very short and not quite coincideut 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 antennse 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. Antennas uniformly honey yellow. 



Described from 9 male, and 1 female specimens.

 autenual club. 



Bseus americanus n. sp. 



Female. — Length 0.fi5'"'". Length of antennal 

 club .185™°!, or in other words the entire body is 

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

 tennal club. Width of antennal club .082""". 

 General color dark honey-yellow ; scape and fun- 

 icle of antenna} brownish, club lighter, dark at 

 tip ; vertex and face light honey-yellow; dorsum 

 (if thorax and abdomen dark honey-yellow, almost 

 approaching mahogany ; legs throughout concolor- 

 OU8 with head ; middle and hind tibi.Te a little 

 darker near base. Surface of abdomen smooth,

J-IG. 59.-Ba>uB americanus. Female- ^""§6 of white pile. Antennal club very large, 

 greatly enlarged (original). longer than rest of funicle and pedicel together; 



fnuicle joints very narrow and short, subequal, 



pedicel wider and as long as entire funicle except club.
