84 HYMENOPTERA OF AMERICA. [PART I. 



bidentate, the teeth arc at times long, sharp, separated by an 

 angular notch ; often less long and separated by a shallow notch 

 like the arc of a circle ; a little carina often parts the anterior 

 margin of the scutel. Wings with some violet reflections. 



Bess. a. cliff. — This is larger and more slender than all the 

 preceding, but smaller than E. olmecus. It makes the transition 

 to the Division Alpha. It has the same coloration as most of 

 the species of the same division, except that it possesses all along 

 each side of the petiole a yellow line. The petiole and the pear 

 of the abdomen are also more elongate, the 2d segment longer 

 than wide. 



Hab. Brazil. 2 ?,U from Bahia. 2 ? (coll. Spinola), from 

 Rio Janeiro. 



The description which Fabricius has given of his E. campa- 

 nulata does not mention the two lateral yellow lines of the petiole, 

 nor the spots of the clypeus, nor does it accord well in the 

 antennae with the E. callimorpha, for which reason we do not dare 

 to assert positively that this is the E. campanulata of Fabr. 



There are probably more than one species very closely allied 

 to this w r hich might be easily confounded with it; /. %., the fol- 

 lowing description which I find in my notes seems to indicate a 

 different species with sulcate mesonotum. 



26. E. incertllS. — E. callimorpho simillimus, at clypeo minus biden- 

 tato, mesonoti disco 2- vel 4-sulcato ; corpore uigro ; an tennis subtus et 

 tibiis extus, ferrugiueis ; pronoti marginibus, petioli lineis literalibus 2 

 et raargine, segmentorumque 20-4°linea praemarginali tenuissima, sul- 

 fureis. 9. 



9. Figure, size, and form the same as that of E. callimorpha, 

 but differs in the clypeus, shining, offering also two carina?, but 

 less strongly bidentate ; its latero-inferior borders sinuate. 

 Thorax a little more distinctly punctured ; the disk of the meso- 

 thorax offers four longitudinal fur roics. 



Insect black, shining, with silvery reflections. Antenna? ferru- 

 ginous beneath ; a fine line bordering the two margins of the 

 prothorax, ferruginous or yellowish. The bordering of the 

 petiole, a little mark on each side of the middle of it, and a spot 

 above tow r ard its base, sulphur-yellow, as well as a fine submar- 

 ginal line upon segments 2-4, both above and beneath ; the 

 rxtreme border of these last, black. Tibia? 1st, 2d, ferruginous 

 before; wings a little smoky.
