Boston Society of Natural History. 
Acrocera stansburyi sp. nov. 
cf 9 Head black, occiput with whitish tomentum, antennae 
yellow. Thorax yellow with three broad narrowly separated 
black stripes (in two specimens, male and female, the stripes 
are fused, forming a large trilobed mark), the dorsal stripe is 
truncate behind at a line corresponding with the base of the 
wings, the lateral stripes are truncate in front at about the middle 
of the dorsal stripe, becoming gradually narrower behind and 
reaching the post-alar callosities, tomentum whitish, pleura on 
the upper half yellow, with large, irregular, black spots, which 
are connected with the black of the lower half, humeri and post- 
alar callosities whitish, scutellum yellow, metanotum black. 
Abdomen yellow, the second segment is margined anteriorly 
with black expanding centrally and forming a dorsal triangle, a 
small dorsal triangle is also present at the base of the third and 
the fourth, with a small spot usually present on the side of the 
third, in one specimen there is a narrow margin similar to that 
on the second segment, ventral segments blackish margined 
with yellow. Legs white, coxae yellow, tips of the tarsi and 
claws black. Wings hyaline, venation as in 0. liturata Will., 
squamae white, halteres yellow. Length, 3mm. 
Eight specimens, Stansbury Island, Great Salt Lake, Utah, 
July 13, 1913 (Hagan and Titus). Holotype and three par- 
atypes in the author’s collection. Two paratypes in the col- 
lection of Mr. H. R. Hagan, one in the Museum of Compara- 
tive Zoology, and one in the U. S. National Museum. 
I had referred this to A. liturata, but it is evidently quite 
different, as indicated by the thoracic and abdominal mark- 
ings and the color of the scutellum. At the request of Mr. Hagon 
I am dedicating it to Howard Stansbury, who made and elabo- 
rate survey of Great Salt Lake and vicinity in 1849 and 1850.
