Discussion. — In the mind of the author there is still some doubt 

 as to the present use of the name subferrugineus. However, the 

 assigimient is made tentatively^ on the strength of Dr. Graham's 

 replies to certain questions pertaining to the type. 



Many of the Central American specimens came from "bat caves." 

 Caudell (1924, p. 136) reported more fully on the Panama specimens 

 under the name A. uhleri, as follows: "Numerous in the guano. All 

 but egg stage obtained. This species was collected by Schwarz and 

 Barber 'in cave earth' at Cacao, Trece Aguas, Guatemala, April 3, 

 1906." These latter specimens were in the series studied.
