DESCRIPTION OF THE SPECIES. 309 



an artificial than about a final location of the species, as the latter 

 will have to depend upon the results of a future investigation. 

 The circumstance that the pyramid of drops beyond the stigma, 

 usually well developed in the species collected in the subgenus 

 Tephritis, is not distinctly marked here, decides me to place the 

 species in Euaresta, although its affinities to the types of this 

 subgenus may be very slight.

Clay-yellow, unicolorous, tbe reticulation of the wings unequally guttate, 

 radiate along the anterior margin and on the apex, more dingy clay- 

 yellow upon the basis and in the middle ; brownish-black along the 

 anterior margin of the wing and upon the apex ; the ovipositor of the 

 female is almost as long as the last four abdominal segments taken 

 together, not flattened, very narrow at the tip, black or brown on the 

 upper side, the under side red towards the basis. Long. corp. £ , 0.17

Observation 1. — Trypeta j "estiva may be considered as a typical 

 form of the genus Euaresta. As the third longitudinal vein of 

 the wings is beset with spines, this species would have to be 

 placed in the genus Oxyphora, in the classification adopted by 

 me for tbe European species. 



Observation 2.— Brazil possesses a conspicuous species closely 

 allied to the present one, but more approaching the next following 

 ones in the pattern of the picture of the wings. I let its descrip- 

 tion follow : — 



T. spectabilis n. sp. % 9 . (Tab. X, f. 27.)— Tota luteola, terebra 

 tamen obscure ferruginea, non depressa et quatuor ultimis abdominis 

 segmentis snbfequalis ; scutellum qnadrisetosum ; alarum pictura nigra, 

 in apice pulchre, sed breviter radiata, adversus angulum posticum 

 rat-ins, in disco rarissime guttata, gutta cellulae posteriori:) priniie unica ; 

 vena longitudinalis tertia setosa.
