Studies of Some Pipunculidae from the Eastern 
United States (Diptera). 
By E. T. Cresson, Jr., Academy of Natural Sciences, 
Philadelphia, Pa. 
This paper is the results of a study of a small collection 
sent to me by Mr. C. W. Johnson, of the Boston Society of 
Natural History, for determination. It is rarely the case when 
a collection of this family is studied, that there are not some 
new forms brought to light. So we find, even in this small 
amount of material, a new species and several of the oppo- 
site sex of those heretofore described. This paper should be 
used in conjunction with my monograph of this family (1) 
to which I often refer. I wish here to acknowledge my indebt- 
edness to Mr. C. W. Johnson for the loan of his type of P. 
jallipes and other specimens, and especially to Dr. P. P. 
Calvert for his kindness in examining the type of lateralis 
Walker in the British Museum of Natural History, and to 
Mr. E. E. Austen for granting Dr. Calvert the privilege to 
examine this type for me. 
Mr. Nathan Banks, while in London during his attendance 
at the Second International Entomological Congress, made a 
few notes on Walker’s types of lateralis, reipublicae and trans- 
latus, but not having made an especial study of this group 
ard having no specimens along for comparison, he unfortu- 
nately did not consider many of the most important characters 
i! his notes and sketches. However, they give some new 
light upon these species, especially lateralis, and as he kindly 
turned over these notes to me, I am indebted to him mainly 
for the results here obtained relative to these species.
