TEXAN IIVMENOPTEItA. 219 



with yellowish-fuscous; legs yellow, coxoe and base of femora 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 deeply 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 line on pleura anteriorly 

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

 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 onlv a yellow spot on each lateral angle of metathorax; wings 

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

 base; the yellow bands 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 process 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 .65 — .80 inch. 



Fifteen % 9 specimens. (Belfrage ; Boll; Heiligbrodt.) Avery 

 handsome and rather variable species, the 9 being easily recognized 

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

 hyaline. 



Bembox texana, n. sp.

 between antennas, 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 tegulee white; wings hyaline; legs white, with a slight yellowish 

 tinge, coxse, 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,
