apex of forewings are two small, greenish spots and on the margin of 

 hindwings a row of ten small, green spots. Ground color on the under 

 side of wings pale, dirty black with a series of twelve silvery spots on the 

 outer margin of secondaries and an additional spot of the same hue on the 

 anal angle and abdominal margin. Exp. 4J/^ inches. 



Habitat, Uganda, Br. East Africa. 



Type, Ehrmann Collection, 



Note: This species is allied to the Nireus group of Papilios, 

 but as I have all the authenticated species of this group, viz. : 

 Papilio lycEus Doubb., P. donaldsoni Sharpe, P. erimus Gray, P. 

 pseudonireus Feld., etc., etc., I do not hesitate in naming this new 

 form. The forewings are more falcated and the hindwings not 

 dentated as in the above-mentioned species. The lower part of 

 the hindwings is more developed than in any of the others of 

 the P. nireus group. 



NOTES ON SOME SPECIES OF THE HOMOPTEROUS GENUS 

 GYPONA (HEMIPTERA). 



By J. R. Malloch, Urbana, 111. 



In Mr. Van Duzeq's Catalogue of the Hemiptera Woodworth's 

 species of Gypona are with two exceptions sunk as synonyms of 

 previously described species. In a recent paper on the genus by 

 E. H. Gibson^ but one species, hipunctulata, is accepted as valid. 



Having access to material identified by Woodworth in the col- 

 lection of the Illinois Natural History Survey which appears to 

 throw some light on the identity of his species I present some 

 notes which clear up a few of the doubtful points in connection 

 therewith. 



It is not at all clear to me why alhimarginata Woodworth has 

 been accepted as a synonym of pectoralis Spangberg as the de- 

 scription obviously can refer to no other than limbatipennis 

 Spangberg. This species was originally described from Illinois. 

 Anyone who has both species available can readily settle the 

 matter for himself by comparing the specimens with Wood- 

 worth's description.
