palporum cum B. spinirostri Koch (loc. cit., 23, 9) congruere 

 videtur: setse vero illse longee pedum posteriorum, qüas ostendit 

 figura Kochii, multo breviores in nostra specie sunt 1 ). 



Fam. Trombidioitlae. 



Gen. Rhagidia n. -). 



Corpus oblongum, angustius, ceplialothorace ab abdomine 

 sulco transverso profundo distincto eoque abrupte angustiore, 

 anteriora versus non multum angustato. 



Rostrum latissimum, crassissimum, e labio convexo, ovato, 

 apice acuminato, sulco transverso notato, mandibulisque duabus 

 labio longioribus, sub-ovatis, apice acuminatis et in chelam di- 

 gitis gracilibus desinentibus, formatum. 



Palpi mediocres, non unguiculati; articulis 4, ultimo crasso 7 

 obtuso. 



Pedes sat longi, articulis 6, spatio inter epimera pedum 2:di 

 et 3:tii paris majore quam sunt reliqua epimerorum interstitia; 

 unguiculis binis fortiter curvatis et pulvillo inter eos oblongo mu- 

 niti; l:mi paris pedes reliquis paullo longiores et crassiores r 

 porrecti. 



') Bdella podurophila White (Suthekland's Journal, Appendix, II, p. ccx, kan 

 ej gerna vara identisk med B. decipiens, då denna sednare alldeles icke har 

 benens femoral-led (art. 2) »muck tkickened», såsom fallet säges vara kos 

 B. podurophila, kvilken beskrifves af White på följande vis: »The beak is 

 nearly half the length of the rest of the body, and is grooved longitudinally 

 down the middle. Its palpi (not shown in the cut) are seemingly threejoiuted. 

 being elbowed after the first Joint, which is nearly three times as long as 

 the two other joints taken together. There are two bristles at the end of 

 the terminal Joint. The four legs of each side are placed in pairs, two 

 being directed forwards and two backwards; the femoral part of these is 

 much thickened. The body is blunt behind, and is thickest just behind the 

 two pairs of legs. As this curious little red species is found on Cornwallis 

 Island associated with the Podura, and as it does not seem to be described, 

 it may be called Bdella podurojihila.» — Beskrifningen åtföljes af en dålig 

 figur i träsnitt, på hvilken någon förtjockning af benens femoral-led ej är 

 antydd. 



2 ) Rhax, genus Galeodoidarum; Rhagidia est dimin. hujus nominis, propter 

 similitudinem quandam cum Solifugis illis usurpatum.
