Psyche 
[June- Sept. 
general body color is red brown or rust colored. Morpho- 
logically it seems certain that there are no specific differ- 
ences between the type and the gaudily marked Panamanian 
specimens. Dorsally the body bears lozenge-shaped marks, 
very distinct in contracted individuals, but much less notice- 
able when the body is extended. A similar conspicuous band 
is present in at least two other Caribbean forms, Macro- 
peripatus torquatus Von Kennel and Peripatus manni Brues, 
as well as in the Andean Oroperipatus peruvianus Brues.

On June 15th, 1940, I was collecting dragonflies along the 
little Jicome river in the lower valley of the Yaque del Norte 
in Santo Domingo. While wading in the streambed below 
the highway bridge (Km. 214, Monte Christi road), and 
crowding my way between some bushes that overhung a 
riffle at a narrows, I disturbed a company of these big brown 
Ascalaphids. A chance stroke of my net against the bushes 
flushed several dozen of them. They fluttered, butterfly-like, 
around my head for a few minutes, and then settled again 
on twigs overhanging the water. 
Later, in the mountains near San Jose de las Matas I 
flushed another colony from the pendant low-hanging bough 
of a large tree where it overhung the riffle in the Iguamo 
river. These also fluttered about wildly for a time, and then 
reassembled on the same boughs, quite disappearing from 
view in the process.
