300 NORTH AMERICAN TRYPETINA. 



surrounding them, appear more coalescent; in the posterior angle 

 of the wing the pale drops are more numerous and somewhat 

 larger than upon the middle of the wing, and moreover, well 

 separated from each other ; the apex of the wing shows between 

 the third and fourth veins a very narrow, hardly apparent hyaline 

 border.

Observation. — In accordance with the explanations given in 

 the second observation to T. angustipennis I leave Trypeta 

 geminata, in spite of its distinctly bristly third vein, in the genus 

 Tephritis, but I do this with the explicit understanding that this 

 position is an unnatural one. In the above-quoted place I haye 

 already explained why one would feel tempted to place this 

 species in the genus Oxyphora on account of the pattern of its 

 picture, as well as of the bristles upon the third vein; but I must 

 again add that this location would not be natural. Its rather 

 stubble-shaped pile, the distribution of the bristles upon the front, 

 and the structure of the antennae indicate a rather close relation- 

 ship to those European species which I have united in the genus 

 Carphotricha ; nevertheless, in some other characters it differs 

 from those species in a measure which prevents its reception in 

 that genus. A number of South American species stand in the 

 same relation to the European Carphotrichse, although they differ 

 among themselves in many very striking plastic characters. A 

 more complete study of these species will result in the breaking 

 up of the genus Carphotricha, based upon too insufficient mate- 

 rial, and then only, in all probability, T. geminata will find its 

 true position.

Clay-yellow, head and feet of a purer yellow; scutellum with four bristles ; 

 the reticulation of the wings, formed of rather large and moderately 

 numerous hyaline drops, is uniformly grayish-brown upon the posterior 

 part of the wings, yellow and brown upon the anterior portion, in such 

 a manner that yellowish drops are mixed among the hyaline ones ; upon 

 the anterior margin, there are five small brown transverse streaks and
