NORTH AMERICAN DIPTERA. 301 



Very common, Massachusetts, Connecticut, New Hampshire, 

 New York, Pennsylvania, Virginia, North Carolina, Georgia, Ne- 

 braska, New Mexico, Arizona. 



This seems to be Walker's species, but it is very probable that it 

 has been described under other names. Specimens from San Domingo 

 I cannot distinguish ; the dorsum of the thorax seems a little less 

 metallic. 

 Jurinia decisa Walker, List, etc., iv, 715. 



Specimens that I identify as this I have from New Hampshire, 

 Connecticut, Virginia, Colorado and New Mexico. The antennae 

 vary in coloration. The small, but conspicuous, brown spot on the 

 anterior cross vein, dark tegulae, and the third joint of the antennae 

 being broader near the end, with the deep red abdomen, will render 

 this species recognizable. 



Echinoniyia (Peleteria) luemorrhoa v. d. Wulp, Tijdschr. v. Ent. (2; 

 ii, 145, pi. iv, figs. 13-16 ; ? Tachina a»taa;ws Walker, List, etc., iv, 726 ; ? E. analis 

 Macquart, Dipt. Exot. ler Suppl. 144,. pi. xii, fig. 3a. 



A number of specimens from the White Mountains agree suffi- 

 ciently closely with Wulp's description ; only one of the two rows 

 of frontal bristles, however, reaches " tot even onder den sprietwortel." 

 In the male the third antenual joint is larger, as long as the second, 

 the abdomen red on the sides, and the fourth segment frequently in 

 large part black. The front tarsi of the female are dilated. A 

 female from Washington does not seem to differ, 



Echiiiomyia (Peleteria) iterans Walker, List, etc., iv, 727; ? Tachina 

 puHctifera Walker, List, etc., iv, 728. 



Numerous specimens from New England, The black of the ab- 

 domen varies from small triangular spots to a subinterrupted median 

 stripe. There are one or two Western species resembling this in the 

 markings of the abdomen, but are apparently distinct. An Echin- 

 omyia (sens, str., i. e., without lateral facial bristles) fi'om California 

 also has the abdomen marked similarly. 



Echinoniyia (Peleteria) fllipalpis Thomsou, Eugeuies Eesa, 517. 



Male.— Second joint of antennae reddish yellow, third as long or longer, black, 

 subcordate ; palpi yellow. Abdomen dark red. first segment, except lateral pos- 

 terior borders, and a broad median stripe reaching to tip of abdomen, black ; 

 second, third, and fourth segments broadly fasciate with grayish pollen ; tibiae 

 chiefly dark reddish. Length 10-12 mm. 



Female. — Third joint of antennae smaller; first abdominal segment at the base, 

 second segment at the middle and a spot exteriorly behind, third segment with 

 a broad posterior band, fourth with a median stripe, black ; front tarsal joints 

 dilated.
