IDENTIFICATION 



Females are readily separated from those of the only other 

 knovm bat- infesting species of this genus, I. ve spertilioni s ty 

 the fact that I . simplex has normal-length Tegs, although the last 

 pair is longer"than usual (all pairs of legs of I. vespertilionis 

 are exceedingly long). Anal grooves are short and divergent. The 

 scutum is slightly longer than broad, has gently curved postero- 

 lateral margins, and converging anterolateral margins; widely 

 scattered, subequal punctations, shallow cervical grooves, no 

 lateral grooves; its color is brownish, reddish, or yellowish. 

 The basis capituli is triangular, without comua or auriculae. 

 Coxae are flat and without spurs. For a fuller description, see 

 Arthur (1956A). 



Msiles are unknown. Immature stages are described by Arthur
