Mouthparts are situated close to the anterior margin of the 

 body. The hypostome formula is 2/2 to 2,5/2,5, the apex is notched 

 and bears a corona of three or four rows of small denticles in 

 four to six files. 



The larval and nymphal illiostrations and descriptions of A, 

 vespertilionis by Neumann (.1896) are quite good, though they shall 

 have to be expaxided for present day purposes. These have been 

 employed subsequently by the same author, Nuttall et al (l90S), 

 Bedford (1934), and others.
