10. Scolia saussurei. (Tab. XII. fig. 9.) 



Nigra, hirta, maculis 2 pronoti postscutelloque flavis; abdomine flavo-bifasciato, apice rufo-hirto; ahs 



fumatis. § . 

 Long, fere 14 millim. 



Hal. Mexico, Jaral in Guanajuato (Schumann). 



Head coarsely punctured; the front ocellus in a deep, round pit. Mesonotum 

 coarsely and strongly punctured all over; the scutellum with the punctures larger 

 and more widely separated. The median segment with the central part finely, the 

 lateral regions more strongly punctured ; the sides projecting, rounded. The head 

 and thorax covered with fulvous hair, that on the median segment being longer 

 and paler. The yellow marks on the pronotum are somewhat triangular. The 

 abdomen above is covered with long fulvous hair, beneath with longer paler hair; 

 the segments are fringed with golden-fulvous hair, the fifth and sixth densely covered 

 all over with fulvous-golden hair ; the basal segments are finely punctured ; the ventral 

 surface is much more strongly punctured, the segments fringed with pale golden hair; 

 the third segment is for the greater part pale yellow, the black basal band projecting 

 in the middle ; the fourth segment is yellow, except for a very narrow black apical 

 band. The legs are black, covered with long pale hair ; the tarsal spines rufous. The 

 wings are fusco-hyaline, the fore margin much darker, the dark band extending from 

 the base to near the apex, the costa dark testaceous. 



ELIS. 



Elis, Fabricius, Syst. Piez. p. 248 (18Q4) (part.); Saussure & Sichel, Cat. Sp. Gen. Scolia, p. 14. 

 Campsomeris, Lepeletier de St.-Fargeau, Hist. Nat. Ins. Hymen, iii. p. 496 (1845). 

 Colpa, Lepeletier de St.-Fargeau, loc. cit. p. 534. 

 Trielis, Saussure & Sichel, Cat. Sp. Gen. Scolia, p. 14. 

 Dielis, Saussure & Sichel, loc. cit. 



As in Scolia, Elis includes two sections — one with three cubital cellules, the other 

 with two only. Kirby, Trans. Ent. Soc. Lond. 1889, p. 443, adopts these as distinct 

 genera, using the name Elis for the section with three cubital cellules = Trielis, and 

 Campsomeris for that with two cubital cellules = Dielis. Of Trielis we have no species 

 recorded from within our limits, and the section is rare in the Nearctic region ; but Dielis 

 contains some of the largest and most striking of the Central American Hymenoptera.
