also taken from a forest deer, Mazama sartorii reperticia 
Goldman, killed near Camp Pital. 
Amblyomma ovale Koch. A female of this species was 
found crawling about on a titi monkey, Saimiri orstedii ors- 
tedii (Reinhardt), when the latter was removed from the 
bag in which it had been placed two or three hours earlier. 
Since this tick was not attached and contained no blood it 
is believed that the monkey was only an accidental host. 
Trombicula dunni Ewing. The mites, or “red bugs,” of 
this species were present in great numbers upon two agou- 
tis, Dasyprocta punctata nuchalis Goldman, and three coatis, 
Nasua narica panamensis Allen, at Camp Pital. They were 
scattered in small groups over nearly all parts of the agou- 
tis with additional large masses appearing as bright red 
spots, nearly 10 mm. in diameter, on either side of the up- 
per and lower jaws, along the edges of the ears and at var- 
ious places on either side of the body over the ribs on both 
these animals. One of them also had one of the masses be- 
neath its chin. They were not so abundant on the coatis and 
were confined mostly to large masses on both ears of each 
of the animals. One of these coatis also had a large patch 
of the red bugs located on the dorsal line about midway of 
its back. These mites proved to represent a new species 
and were named and described by Ewing. 
I wish to express my thanks and appreciation to Dr. H. 
C. Clark, for his aid in collecting many of the specimens, 
and also to Dr. C. T. Greene, Dr. J. Bequsert, Dr. 0. Krober, 
Dr. G. F. Ferris, Dr. H. E. Ewing, Dr. Karl Jordan and 
Dr. F. W. Edwards for their kindness in identifying many 
specimens of the various groups for me.
