90 E. T. CRESSON. 



first segment of abdomen, obtusely emarginate within and nearly meeting on 

 apical middle, and narrow uninterrupted apical margins of segments 2 — 4, pale 

 buff; basal joint of flagellum ferruginous; mesothorax and pleura finely and 

 densely punctured; scutellum subbisinuate behind, with short lateral teeth; 

 wings pale fuscous; legs brown, coxae, tibiae and tarsi with cinereous pubes- 

 cence; last ventral segment broadly rounded at tip. Length .45 inch. 

 Ilab. — Mexico, (Sumichrast). Two specimens. 



Epeolus mexicanus. — % 9-— Black; face, line on occiput, posterior 

 margin of prothorax, tubercles, line over tegulse, continued before scutellum, 

 narrow line behind scutellum, sides of metathorax, lunate patch on pleura, 

 large obliquely sublunate patch on each side of first abdominal segment, and 

 rather broad band on apex of segments 2—4 J, 2 — 6 %, all covered with a 

 dense appressed yellowish pubescence, sometimes changing in certain lights to 

 silvery-white; the band on prothorax and markings of abdomen varies from 

 pale yellow to dark buff; legs, extreme sides of abdomen, broad on apical 

 segment 9 j and venter clothed with a very short fine cinereous pile; base of 

 flagellum and tegulse ferruginous; mesothorax closely and confluently punc- 

 tured; wings varied with dusky, darker on apical margin, yellowish at base; 

 tibiae and tarsi often more or less varied with ferruginous; apical ventral 

 segment of 9 convex and broadly rounded at tip; % with a band of cinereous 

 pubescence on ventral segments two and three, and fringe of long yellow 

 pubescence on four and five. Length .35 — .45 inch. 



Hab. — Mexico, (Sumichrast). Sixteen specimens. Kesembles/wmv!^ 

 pennis Say, but readily distinguished by the obliquely sublunate pubes- 

 cent patch on each side of first abdominal segment and the bands on 

 remaining segments except the last; fumipennis has a transverse sub- 

 lunate mark on each side of the first segment and a band only on the 

 second, and the scutellum and legs are always ferruginous. 



£l>eolu!<igIakratiis.— '^ .—Shining black; vertex, mesothorax, scutellum 

 and pleura coarsely and sparsely punctured; tips of mandibles, labrum, three 

 or four basal joints of antennae, anterior lateral corners of mesothorax, tuber- 

 cles, tegulae, scutellum, legs and two basal segments of abdomen except apical 

 margins, ferruginous; face, thorax beneath, posterior margin of scutellum and 

 sides of metathorax densely silvery; upper margin of prothorax yellowish; 

 scutellum strongly emarginate medially, the lateral teeth broad, acute and 

 prominent; abdomen finely punctured, smooth and shining, nude, except a 

 patch of pale pubescence at base of first segment and a narrow submarginal 

 band, (broader laterally and narrowed and interrupted on middle) on all the 

 segments except the last; ventral segments two and three with apical margin 

 whitish and four and five with an apical fringe of long curved yellowish pubes- 

 cence; wings fuliginous, darker at apex. Length .35 inch. 



Hah. — Georgia, (Morrison). One specimen. This is congeneric 

 with what I take to be the zonutus of Smith, having the abdomen 

 smooth and shining, the form shorter and more robust, etc. This 

 however differs from that species by the coarse sculpturing of the 

 thorax and the deeply emarginate scutellum.
