To the present species Saussure's A. jallax shows nearest rela- 

 tionship, of which species a series is before us representing locaUties 

 from Mexico to Costa Rica. 



That the Lateralis Group is large and includes many species 

 superficially very similar, is well demonstrated by numerous Cen- 

 tral and South American examples before us. The male genitalia, 

 though not widely differing in some of the species, we believe 

 afford in themselves diagnostic differences for all the species of 

 this group. 



Little variation is noted in the large series of the present species 

 at hand. The tegmina in all extend slightly beyond the apex 

 of the abdomen, if the abdominal segments are in normal position.
