TEXAN HYMENOPTERA. 219 



m 



with yellowish-fuscous; legs yellow, coxae and base of fcmo.-a black; first seg- 

 ment of abdomen black with a large subovate yellow spot on each side, some- 

 times meeting on the disk and forming a broad band, sometimes the segment 

 is yellow, with only basal and apical margins black; segments 2 — 5 each with 

 a broad yellow band almost covering the segment, that of second segment 

 generally enclosing two transverse black spots near base, those on the follow- 

 ing segments more or less deejily indented with black on each side of basal 

 middle, the basal and apical middle more or less emarginate with black ; apical 

 segment black, densely punctured; apical segments more or less clothed with 

 black pubescence, shining black, segments 2—4 each with a yellow lateral spot. 

 Length .75 inch. 



'^.—Thorax generally black, immaculate except a lino on pleura anteriorly 

 covering the tubercles, sometimes the sides of prothorax and a line over legulte 

 are yellow; one specimen has a spot on each side of scutellum and a slender 

 line on postscutellum yellow and the metathorax marked as in 9, and another 

 specimen has only a yellow spot on each lateral angle of metathorax; wings 

 generally entirely hyaline, sometimes there is a faint fuscous cloud towards 

 base; the yellow bauds on abdomen are narrower than in 9> with the emar- 

 ginations larger and deeper, giving the bands a biundulate appearance; second 

 ventral segment with a large hooked process on basal middle, very robust and 

 broad at base and slender and acute at tip, this jarocess is sometimes much re- 

 duced and in one specimen it is indicated merely by a slightly raised line; 

 apical segment with a process shaped much like that on second segment, but 

 smaller, and with a prominent carina on each side. Length .05 — .80 inch. 



Fifteen % $ specimens. (Belfrage ; Boll ; Ileiligbrodt.) A very 

 handsome and rather variable species, the 9 being easily recoonized 

 by the conspicuously clouded wings, which in the S are generally 

 hyaline. 



Beiubex tc.xana, n. sp. 



9.— Black, head, thorax and base of abdomen clothed with a fine white 

 pubescence; anterior orbits not reaching summit of eyes, posterior orbits, spot 

 between antennae, clypeus except two connected black spots at base, labrum 

 and mandibles except tips, white; scape white beneath; thorax rather closely 

 and delicately punctured; narrow posterior and and lateral margins of protho- 

 rax, covering tubercles, a large spot on each side, a short transverse line be- 

 neath wings, and a small spot on each lateral angle of metathorax, white ; an- 

 terior half of tegulae white; wings hyaline; legs white, with a slight yellowish 

 tinge, coxae, femora except more or less of tips, a stripe on all the tibiae within 

 and on outer side of anterior pair, black; abdomen black, shining, a large 

 transverse white spot on each side of first segment, a broad white band on 

 middle of second segment deeply notched on anterior and posterior middle and 

 enclosing two transverse black spots on each side of disk, and a biundulate 

 white band on third, fourth and fifth segments, dilated laterally and deeply 

 indented with black on each side of anterior middle; apical segment entirely 

 black, densely punctured ; venter shining black, the segments, except the last, 

 with a small white spot on each apical corner. Length .75 inch.
