92 HETEROCHRÜA PICTIPENNIS. 



side moreover a shorter oue above the middle-coxae. An- 

 terior margin of the abdominal segments black or blackish 

 brown. Legs pale ochraceous, with a brown ring before 

 the tip of the femora. Wings much longer than the ab- 

 domen, yellowish at the base as far as the end of the sub- 

 costal vein (on about one third of the length of the wing), 

 furthermore with a darkbrown and whitish pattern ; whitish 

 spots around both cross-veins ■ also invading the cells above 

 and beneath them ; moreover there are two rounded whitish 

 spots, connected together, in the centrum of the cubital 

 cell and of the first posterior cell ; there is another , some- 

 what trigonal one, in the second posterior cell, and finally 

 a pair of semicircular ones at the end of the wing; the 

 veins , as far as they traverse the dark pattern , are thicke- 

 ned and black ; the postical vein reaches the wing border. 



A 9 from Chili (Dohrn). 



The three species of the genus Heterochroa may be dis- 

 tinguished by the following characters: H. picta shows on 

 the thoracic dorsum three black stripes; in pictipennis and 

 bicolor there are but two, the intermediate one having disappea- 

 red; hicolor has the wings immaculate, almost hyaline, in 

 both the others the wings have a brownish and whitish 

 pattern. In picta the dark pattern covers the discal cross- 

 vein ; in pictipennis on the contrary this cross-vein lies in 

 the hyaline or whitish part ; moreover in picta the postical 

 vein does not touch the wing border , whilst it is continued 

 down to the end in both the other species.
