a cloud. Pollen of head and abdomen old gold in color; fifth 

 sternite retracted in the spread specimen; no median marginals on 

 second segment; sternopleural 2, 1. Middle tibia with one bristle 

 on outer front side, hind tibia (fig. 9&) with very dense, villous hair 

 on inner side; hind femur attached to trochanter at an angle, tro- 

 chanter with stubby spines on lower hind edge. Leg more decidely 

 bent at base than in cimbicis, and femur more slender. Forceps from 

 behind (fig. 9a) very distinctive; penis like that of clmhicts as far 

 as I can see. 



Enderlein has made this species the type of his new genus 

 Dasyfroctia^^^ but this genus can not be more than a synonym of 

 Boettcheria as it is very close to the type species of the latter, 

 latisterna Parker, 



Sarcophaga setulosa^ p. 276. 



One male. This is a rather small specimen of cimbicis Townsend," 

 which was fully redescribed by Parker under the name BoettcheHa 

 fernaldi *^ with figures. I have examined types of all. 



Sarcophaga turhata^ p. 276. 



One male, four females. One female (Orizaba) has been correctly 

 set apart by Austen as a different species and I exchide it. The male 

 has three dorsocentrals, hind tibiae not villous, genital segments red ; 

 first vein bare; palpi black; anterior acrostichals well developed; 

 and runs to i^is on page 114 of Sarcophaga and Allies, but difi'ers 

 in the genitalia at least. There are one or two slender hairs on the 

 inner side of the hind tibia, suggesting the beginning of villosity. 

 The head and last two abdominal segments have golden pollen; 

 first and second segments with median stripe which hardly extends 

 upon third ; third and fourth on venter with long pile, some of which 

 is pale, the fourth black in ground color. Sternopleural 2, 1; scu- 

 tellum damaged, but at least with good-sized apicals. Cheek over 

 one-fourth eye height; parafacial hairs all minute. Genitalia as in 

 Figure 10. First genital segment a little brown on sides, with no 

 distinct bristles ; second red with a few bristly hairs. 



Turbata is designated the type of Dienchaeta new genus by Ender- 

 lein (1928, p. 16) ; unfortunately I did not have his paper at hand 

 and can not confirm the existence of the principal character he uses 

 to define the genus — the presence of two pairs of lateral scutellars. 



Sarcophaga trivialis, p. 277. 



Seventeen males, nine females. I spread the genitalia of all 

 males, and sorted them into ten species. One belong to the Boett-
