Hystrichopsylla tripectinata Tiraboschi, Boll. So;. Z-i<tl. Itnl. xi. p. lO'l. plate (11(02) (Italy). 



We proposed Stenoponia for tripectinata and coelestis in Proc. Zool. Sac. 

 Land., p. 391 (1011). The chief distinctions are the four-segmented labial palpi 

 and the presence of one receptacnlaiu seminis instead of two as in IIi/.itrichop^i/lh. 



S. tripectinata is a Mediterranean species known from Italy, Asia Minor and 

 the Azores. We met with it only on the Hants Plateanx.

Only the pronotal comb is developed in this species, but there are some short 

 stout spines at the apices of the nietauotniu and the first three abdominal tergites 

 which are presumably remnants of four more combs. From the presence of these 

 vestigial combs we may conclude that species e.\ist or have e.Kisted with these 

 combs fully developed. R. unipectinata agrees in all essentials best with Ischno- 

 psyllus, apart from the male genitalia, which are of a difiereut type.
