Females have elliptical, open anal grooves. Coxa I has a 

 concave posterior border prolonged internally to a long spine 

 and external Ty to a shorter spine. The scutum is longer than 

 broad, broadest at anterior third; it lacks lateral grooves, 

 has niunerous deep, xmiform punctations, and its cervical grooves 

 diverge from the anterior third and are deeper posteriorly than 

 they are anteriorly. The basis capituli ventrally has pointed, 

 retrograde spurs (aviriculae). Total length of gorged specimens 

 may reach 7.0 mm. 



The nymph has been described and figured by Nuttall and 

 Warburton (1911). The larva is described by Arthur (ms.), who 

 also redescribes the nymph and both sexes of adults.
