Cuterehra bseri Shannon & Green. Four large, mature 
larvae of this species were collected by Dr. Wislocki from a 
young, black howling monkey, Alouatta palliata inconsonans 
Goldman, that was killed at Puerto Armuelles on July 27, 
1929. These four larvae were located in the skin in the reg- 
ion of the neck and an empty nodular pocket from which a 
fifth larva apparently had emerged was nearby. Three 
other young howling monkeys were shot at the same time. 
One of these was infested with a small, immature larva of 
this species. The other two each bore a number of empty 
nodular pockets from which it is more than likely that lar- 
vae of this species had emerged a short time previously. 
Specimens of the larvae were reared to adult flies in order to 
confirm the identifications. Larvae of this species were col- 
lected in the Darien region by J. L. Baer, in 1924, and have 
been reported upon by Shannon and Green (1). Since 
there seems to be no record of this species having been taken 
in Chiriqui this is probably the first report of its presence 
in Western Panama. 
Dermatobia hominis Linnaeus. A larva of this species 
located itself on the inner side of Dr. Clark’s elbow at Camp 
La Vaca in February, 1930. Two coatis, Nasua narica pan - 
amensis Allen, killed at Camp Pital, were found to be in- 
fested with larvae of this species. A mature larva, about 
21 mm. in length, was located in the right femoral region 
of one of the animals. The second coati was infested with 
two of the larvae. They were approximately two-thirds 
mature and were situated at about the middle of the ani- 
mal’s tail, but little more than an inch apart. The tail was 
badly swollen, crooked at an obtuse angle and looked as 
though it were broken. From the appearance of the lesions 
one would assume that both these animals had suffered a 
considerable amount of pain and discomfort from the pres- 
ence of these larvae. 
Gastrophilus nasalis Linnaeus. A total of 58 of the larvse, 
or “bots,” of this species was found in a horse that was 
autopsied at Progreso, Chiriqui, on August 25, 1931. Fifty- 
six of these larvae were clustered to form a rosette near the
