380 NORTH AMERICAN DIPTBRA. 



Figs. 71 and 76. Xanthomelanodes arcuata. Figure evidently 

 made from an oblique viewpoint. Xantlwmclana is preoccupied in 

 Aves (Bonaparte, 1850). 



Figs. 72, 75. Sarcotnacronychia, sp. Not Pachyophthalntus. I 

 five elsewhere distinctive differences. 



Figs- 73. 74- Goniochceta plagiodes. A small costal spine some- 

 times. The frontal and parafacial bristles usually appear as a con- 

 tinuous row, the latter directed downward. The foremost frontali 

 inserted opposite base of third joint. There are three proclinate orbi- 

 tal bristles in each sex, the middle ones sometimes weak. 



Fig. 78. Sibhona illinoisensis. Differs from geniculate in the 

 widened and flattened third antennal joint, convexity of third aristal 

 joint, etc. 



Figs. 80, 81. Euthera tentatrix. The second antennal joint is 

 sometimes almost as long as the third, the latter in such case being 

 shortened so as to make the antennae scarcely longer than face. The 

 third joint is normally of equal width throughout; truncate at tip. 



Fig. 82. Drepanoglossa lucens. The anterior upper fronto-orbital(re- 

 clinate) bristle is stronger than any other save the vertical. I give 

 elsewhere the differences between Epigrimyia and Drepanoglossa. 



Figs. 84, 85. Euthyprosopa peliolata. Compared with cotype the 

 front pair of ocellar bristles is longer than shown in figure, and third 

 antennal joint is pointed at apex. The frontal bristles are shorter. 

 The hind cross-vein may be nearer the angle of the fourth vein in 

 some specimens than in others. 



Fig. 87. Chcetogcedia acroglossoides. Apparently the male of /-'rou- 

 tine! acroglossoides Towns. I give elsewhere distinctions between this 

 species and Baumhaueria ana/is Wulp, with notes on Chestogeedia, 

 and an allied new genus. The figure should show the outer row of 

 frontal bristles differentiated from the bristly hairs of parafrontals and 

 the second antennal joint longer to agree with eastern specimens 

 which I am inclined to identify as this species. 



Fig. 89. Atropharista jurinoides. I give reasons elsewhere for 

 maintaining this ^enus. 



Fig. 91. Eujurinia pollinosa. I propose this name for Hystricia 

 pollinosa Wulp. A specimen from Mexico differs from the figure in 

 the somewhat wider cheeks and the not bowed palpi. 



Fig. 92. Euclytta flava. I propose the new genus Euclytia for Cly- 

 tiaflava and give particulars elsewhere. 



Fig. 93. Neofischeria flava Towns. 11. g. et n. sp. The genus and 

 species are characterized elsewhere. This is not Demoiicus venatoris 

 Coq., which by the way is not a Demoiicus, and for which I propose 

 the new genus Parafischeria. The figure should show the well de- 

 veloped palpi, which are elongate, a little thickened distally and 

 slightly curved. 



Fig. 94. Hyphantrophaga hyPhan trice, male. The parafacials be- 

 low ami the cheeks should be narrower to agree with topotypes in the 

 National Museum.
