34 E. T. CRESSON. 



fifat.— Mexico. Prof. Sumichrasfc. Three specimens. Easily re- 

 cognized by the apex of abdomen being broadly yellow. 



9. Ijom'ospis flnbsosa, n. sp. 



5. — Differs from azteca only as follows: — Smaller; posterior fe- 

 mora entirely black ; abdomen with a narrow yellow band at apex of 

 first segment and another at apex of third segment; apical segment 

 entirely black, sericeous; wings fuliginous, paler ou posterior half. 

 Length .lis inch. 



Hub. — Mexico. Prof. Sumichrast. One specimen. May prove to 

 be only a variety of azteca. 



10. Ijeucospiti tolteoa. n. sp. 



9 . — Black, densely punctured ; head tinged with dark green, clothed with a 

 silvery sericeous pubescence; mandibles tinged with rufous; antennae black, 

 reddish at base of flagellum beneath, scape yellowish-white beneath : two nar- 

 row bands on prothorax, the anterior one more or less interrupted and abbre- 

 viated, (sometimes the posterior one is obsolete), the lateral margin of meso- 

 thorax and a broad band on posterior margin, before scutellum, yellow ; scutel- 

 lum immaculate, slightly tinged with green; metathorax pale ferruginous, 

 densely clothed with silver}' pubescence; tegulae brown; wings pale fuscous, 

 with a central longitudinal, hyaline streak; legs black, sericeous, coxae more or 

 less tinged with brown; a short stripe on anterior femora at tips above, their 

 tibiae in front, extreme tips of intermediate femora and base of their tibiae, 

 small spot at tip of posterior coxae, a broad stripe on their femora above, 

 not reaching base, and another beneath from large tooth to base, and their tibiae, 

 all yellow; tarsi pale fulvous ; femoral teeth minute; abdomen short, robust, 

 ■slightly contracted at apex of first segment, densely and finely punctured, 

 clothed with a very short silvery sericeous pile ; first segment shining, green 

 above, with a deep piceous excavation at base, and before the apex a smooth 

 polished piceous band ; second and third segments each with a broad apical 

 band of sericeous pubescence, changing from silvery to pale golden-green when 

 viewed in certain lights; ovipositor short, porrect, not reaching to base of third 

 segment, although the groove extends quite to base of second segment. Length 

 .25 inch. 



% . — Differs only in the shape, color and sculpture of the abdomen, which is 

 elavate,more strongly tinged with green, the second segment being much con- 

 tracted at base ; first segment less shining, more deeply and coarsely punc- 

 tured, with no piceous band near apex, apex of abdomen clothed with a golden 

 green pubescence, and the terminal segment very small. Length .25 inch. 



Hah. — Mexico. Prof. Sumichrast. Four 9 , one % specimens. 

 This is our smallest species, resembling Sumichrastii more than any of 

 its congeners ; the form is, however, not so robust and the $ abdomen 

 not abruptly narrowed at base of second segment ; the yellow markings 

 of thorax and the silvery bands of abdomen will easily distinguish this 

 from Sumivhrastii.
