Nymph 

 From the material before me there appears to be two nymphal stages. Fully gorged 

 nymph (last nymphal stage) 4.5 mm. in length by 2 mm. in width. In general shape 

 nymph closely resembles adult with no marked difference except size and absence of 

 genital opening. Capitulum practically identical with that of adult except that at base 

 of hypostome there are two very long spines that occupy the same position as the two 

 short ones do in the adult. 



Larva 



Fully gorged larva practically spherical in shape, the long legs and capitulum pro- 

 jecting far beyond margins of body; length, exclusive of capitulum 2.3 mm.; capitulum 

 0.64 mm.; extreme width 2.3 mm. Hypostome of larva practically identical with that 

 of O. azteci (Fig. 4, b). Integument of partially gorged larva with beautiful arrangement 

 of fine parallel lines running in various directions on body. 



HOSTS AND DISTRIBUTION 



Types are in the collections of the Department of Entomology, Cornell 

 University, Ithaca, N. Y. 



Matheson (1935) states that the larvae of this species were taken on the 

 short-tailed bat, Hemiderma per s picillatum aztecum (Saussure), March 30, 

 1931, by Mr. A. L. Brody and that the same collector found nymphs and 

 adults in crevices of the walls and ceilings of the Chilibrillo Caves, Panama. 

 Eggs were also found in association with the adults. No further collections of 

 the species have been reported.
