148 PSYCHOPSIS NEBULOSA. 



tions the penis is visible as a very complicated organ and the 

 genital valve(?), which I have indicated in the two figures 

 between the app. sup. and the last sternit, is also very compli- 

 cated and very different in the two species. The last sternit is 

 like the app. sup. very well visible ia the dried insect and 

 much larger in zebra with the tip curved a little up- 

 wards, when seen sideways. Seen from the underside it is a 

 triangle with an elongated tip in zebra, in nebulosa it is 

 quadrangular with the hindborder straight. 

 Body 11 — 13. Forewiug 15—20. Hindw. 12—16. Ant. 5—6. 

 Abd. 6—8. Gr. br.8'/2— 11. Gr. br. 6— 8. 

 App. cf 2. 



A couple from the Zambesi in my collection ; a smaller 

 male from South-Africa in the collection of Prof. Mabille 

 in Paris, and in the British Museum I saw a specimen 

 from Mashonaland.
