CALVERT: ODONATA OF PARAGUAY. 35 



description is very brief and. was based oii aii imperfectly preser- 

 ved femalefrom Guayaquil of the form and size of discolor {= fer- 

 Tuginea), «aber die Flügelspitzen bis zum Pterostigma kastanien- 

 braun, die Binden [on tlie thorax] breiter und scliwefelgelb, die 

 Unterlipj)e scliwefelgelb inderMitte mit breiter scliwarzerBinde». 

 If « bis zum Pterostigma » means merely to tlie outer end of the 

 pterostigma tlie description migbt apply to tlie figure oí flavojñcta 

 Kirby (Trans. Zool. Soc. Lond. xii, pl. liv, f. 1), wliich has such a 

 labium. The placing of sulphurata in the above table under the 

 heading « pterostigma long » is based on Hagen's statement that it 

 is « von Form und Grrosse des O. díscolo^' ». 



A much damaged f emale from Payta, Perú, in the United States 

 National Museum, agrees with this brief description o f sulphurata; 

 I do nod find any structural difference from ferruginea. In the 

 same collection is a male from Surinam which has a broad black 

 median band on the labium; so also has a feínale from Hayti (in 

 the Academy of Natural Sciences of Philadelphia); thesetwo have 

 the tips of the wings almost clear, so that I refer them to ferrugi- 

 nea^ but they evidently form a transition to sulphurata. 



Flavopicta Kirby (1. c.) is represented in the Museum of Com- 

 parative Zoology by a damaged male labeled, in Barón de Selys' 

 hand, « L. appendiculata Selys». This ñame (no description pu- 

 blished) is given by Hagen in (Proc. Bost. Soc. Nat. Hist. xviii, 

 p. 85, 1875), who on the same page remarhs of cidtriformis «Pro- 

 bably not different from L. appendiculata ^y. Judging from the 

 •specimens now at hand, however, the color of the abdomen, as gi- 

 ven in the preceding table, seems to sepárate them distinctly. It 

 may here be remarked that while Mr. Kirby's figure shows the ab- 

 domen of flavopicta to be obscure brownish, his description (p. 332) 

 speaks of the abdomen as reddish above, but since reddish unes 

 are said (p, 333) to continué on eacli side of the lateral carinae, 

 some clerical error has probably occurred. Hagen's specimen agrees 

 with that figure very well, and its genitalia agree with the figure 

 -and description given above for those of cultriformis.
