272 NORTH AMERICAN TRYPETINA. 



closely allied to the species of Hexachseta, in which, however, as 

 far as I know them, the fifth vein has bristles upon the basis only, 

 while in the present species the bristles almost reach to the tip. 

 For this reason, as well as on account of the different character 

 of the picture of the wings, I do not deem it convenient to place 

 it in the genus Hexachseta. Whether Mr. Saunders's genus 

 Dasyneura would better answer for it, I am unable to say, as I 

 have not been able to procure the publication which contains it. 

 For the present therefore I set this species up as the type of a 

 new genus, which I call Blepharoneura. 



28. T. testudinea n. sp. (Tab. XI, f. 13.)— Ex luteo fusca, capite, 

 thoracis dorso, pedibusque luteis, terebra duobus ultimis abdominis 

 segmentis semel sumtis paulo longiore; alae valde dilatatae, e nigro 

 fuscse, strigis duabus hyalinis inde a margine cellulse posterioris 

 secundae usque ad venam longitudinalem tertiam ascendentibus, primo 

 limbi costalis diraidio grosse nigro maculato, disco alarum guttulis 

 minutis pellucidis confertim asperso. 



Yellowish-brown, head, thoracic dorsum, and feet clay-yellow ; the ovi- 

 positor only a little longer than the last two abdominal segments taken 

 together ; wings very broad, blackish-brown ; two hyaline indentations 

 reach from the posterior side of the second posterior cell to the third 

 longitudinal vein ; the anterior half of the region along the costa shows 

 a number of large, black spots ; the central portion of the wing is 

 occupied by many small, hyaline drops. Long. corp. cum terebra 0.21 ; 

 long. al. 0.19. 



A species very much resembling the T. latipennis Wied., but 

 differing in the smaller size and the less minute dots on the 

 central portion of the wing. The coloring of the body is yel- 

 lowish-brown, but may be somewhat darker in fully colored spe- 

 cimens. The ground color of a great part of the upper side of 

 the thorax is blackish, but very much concealed under a thick 

 clay-yellow pollen. Front opaque, of a moderate breadth, still 

 narrower anteriorly; the usual frontal bristles are brown. Eyes 

 large, elongated; cheeks very narrow, with much pile; face short, 

 descending rather perpendicularly, but distinctly excavated under 

 the antennas; the anterior edge of the mouth not projecting. 

 Antennae ochre-yellow, of a medium length, but, owing to the 

 shortness of the face, reaching to the anterior edge of the mouth ; 

 the third joint has a rather rounded anterior comer; the mode- 

 rately long arista thin and bare. The middle of the thoracic
