above upper part of tympanum; skin of throat and chest smooth, 

 that of belly and lower surface of thigh uniformly and very finely 

 granular; no traces of a skinfold across chest; subadult female, no 

 vocal sac. Skin of head not co-ossified with skull, roof of skull not 

 exostosed. 



Dimensions. — Head and body, 33 mm.; head length, 10.9 mm.; 

 head width, 10.6 mm.; femur, 17.7 mm.; tibia, 17.4 mm.; heel-to-toe, 

 21.8 mm.; hand, 9.4 mm. 



Color in alcohol. — Clear pale yellow above and below with a distinct 

 pattern dorsally of small red spots and stripes. A distinct but quite 

 narrow red stripe originates on each side above tympanum and 

 passes posteriorly to region of the sacral hump where it fades out. On 

 top of head and back and on the dorsal surfaces of forearms, thighs, 

 and shanks are scattered tiny but distinct cardinal red spots. There 

 are two such spots on top of head, two on each forearm, three on 

 right thigh, two on left thigh, four on right shank, five on left shank, 

 and sixteen scattered over the back. Except for these red markings, 

 the entire specimen is clear, pale yellow. 



Remarks. — This frog seems to be another of the species endemic of 

 Serrania de La Macarena. 



After several years in preservative the type has faded to a pallid 

 yellow and might be taken at a glance for some of the other "green" 

 Hyla from northern South America, although careful inspection will 

 demonstrate its definitive characters of a small tympanum and the 

 greatly reduced webbing. We did not see the specimen alive but while 

 still fresh it was spectacularly colored with its brilliant red dorso- 

 lateral stripes and with the dorsal surfaces flecked with bright red as 

 though someone had sprinkled it with cayenne pepper.

Diagnosis. — A small "green" Hyla with greatly reduced webbing 

 between the fingers, with small patches of vomerine teeth. 



H. rhodoporus may be distinguished from rubeola by its sturdier 

 build and the absence of dorsolateral stripes. It differs from punctata 

 by having the tympanum equal to about three-fourths (rather than 

 one-half to three-fifths) the diameter of the eye. 



Description. — CNHM 81786, Villavicencio, Meta, Colombia. Vo- 

 merine teeth iu two short, somewhat rounded patches, lying close 

 together between the moderate-sized, rather oblong choanae; tongue 

 one-half as wide as mouth opening, broader than long, its posterior
