Ranaira annulipes Stal. Of. Vet. Ak. Forh., 1854, p. 241-1. Prsecedentibus 

 duabus affinis et cum iisdem divisionem forma metasterni distinctissimam, 

 Americam habitantem formans. Secundum formam metasterni in divisiones 

 quattuor distinctas, determinationem specierum facilitantes dividi potest 

 Ranatra genus." 



Doctor Montandon (Bui. Soc. Sci. Bucharest, XVIII, 1910) , who 

 has examined Guerin's type of R. fabricii (1857) pronounces it to 

 be the same as R. annulipes Stal, 1854. Sagra's Historia fisica, po- 

 litica y natural de la Isla de Cuba, volume VII (1857) is not avail- 

 able to many of our workers; therefore, Guerin-Meneville's descrip- 

 tion of R. fabricii follows: 



Ranatra fusca tubo respiratorio corpora paulo longiore ; pedibus anteriori- 

 bus nigro-fuscis ; corpoie infra obscure feiTUgineo. Larg. 35, Anch. 3 millim. 



Notes. This species is distinguished from all our species by hav- 

 ing the connexivum of the genital segment enlarged and extended 

 ventrally at the caudal end embracing the distal portion of the geni- 

 tal operculum (see fig. 11, pi. XLV). I have never seen specimens 

 of this species from the United States and Prof. H. G. Barber in- 

 forms me that his record from Texas was on a mistaken identifica- 

 tion. Mr. W. L. McAfee says the species appears to be common 

 in Cuba. 



Ranatra fusca Palisot Beauvois. 



Palisot de Beauvois, A. M. F. J., Ins. Rec. Afr. Am., p. 235; 1805. 

 (= R. Americana Montd., 1910, and subsequent writers.) 



Original description: 



RanaUre brune. Brune-verdatre ; soies un peu plus courtes que le corps; 

 ailes brunes-roligeatres. (Fig. 1.) 



Ranatra fusca. V«ridi-f usca ; setis corpore brevioribus; alis fusco-rubellis. 

 (Fig. 1.) Etats-Unis d'Amerique. 



Obs. Cette espe^p differe de celle d'Europe par sa couleur plus pale, par les 

 soies qui terminent I'abdomen, plus courtes que le corps, par les ailes et le 

 dessus de I'abdomen d'un brun rougeJitre. 



Notes. A photographic reproduction of Palisot's figure (natural 

 size) is given on plate XLIX, figure 1. On a previous page I have 

 stated the evidence to show that Palisot's illustration is natural size. 

 Size alone shows that Palisot's species is not the same as R. kir- 

 kaldyi Bueno. It also eliminated R. nigra H. S. {= R. protensa 

 Montd.). The short legs and stout front femora eliminate R. fusca
