XXXIV. — New Species and Forms o/'SphinQ;iil;B. 

 By J. J. JoiCEY, F.E.S., and \V. J. Kaye, F.E.S. 



The eight new species of Spliing-idjB here described will be 

 figured after the war. Xylophanes suhlcevis is a very old 

 specimen acquired from a collection made about the year 

 1844, but it appears to be undescribed, and if so it would 

 seem to be a very rare insect. Hippotion rubribrenna n ) 

 doubt exists in several collections, there are a number at 

 Tring Museum ; but to us it has a distinct appearance, u-liich 

 is also easily definable. It was unfortunate to have had an 

 accident with the genital preparation, but those who have 

 specimens will be able to verify our contention by examining 

 the male organs. Marumba irata is a striking novelty from 

 Tibet, a district from whence many interesting things are 

 now being sent. O.vyambidi/x citrona adds still another to 

 the already long list of closely allied Oxyambuh/x species. 

 The male clasp is different from both 0. schauffdbergeri and 

 0. sericeipennis, while in general appearance it is different 

 from 0. sericeipennis in many minor points, but not at all 

 like 0. schauffelbergeri. 



Oligographa mosambiquensis, sp. n. 



Fore wing various shades of brown^ not grey as in 0. 

 juniperi and also narrower. Darkest at base, with dark lines 

 along u])per and lower edge of cell. A number of dark 

 streaks on or between the veins. An apical wavy line from 

 apex for a short distance as \x\ jnnip)eri. Discoidal spot large, 

 white (much larger than in juniperi). Hind wing dark 

 brown, unicolorous. Abdomen dull brown, with a faint 

 central line. Wings below pale greyish brown. Underside 

 of abdomen whitish. 



Hab. S.E. Africa, Delagoa Bay. 



Type in Coll. Joicey. 



Marumba irata, sp. n. 



Fore Aving with the ground-colour violet-pink. The small 

 basal area dark brown. Across the centre of cell is a bunch 

 of four transverse lines the outer two of which are greatly 

 curved and parallel. Small discoidal spot black. Beyond
