(dr. a. C. OtJDEMANSX NOTES ON ACABI. 107 



Episfoma very variable; the variations lying; between the usual 

 types of the protonympha and of the tritonympha. 



Mandibles chelate, multidentate, resembling those of the trito- 

 nympha feminina. 



Maxillae. Hypostoma and palps resembling those of the trito- 

 nympha feminina. 



Legs slender; no particulars, 



6. Macrocheles longispinosus (Kram.) 



In the Tijdschrift voor Entomologie, v. 4"), p. 42 and 43, (10 

 Sept. 1902) I described and delineated (pi. 5, fig. 97—100) a 

 protonympha of Macrocheles longlsphiosus (Kram.) under the name 

 of Macrocheles tridentinus (G. et R. Can.). After careful examin- 

 ation I even observe novi', that I have delineated and described 

 the epiStoma quite wrongly. It ends only in a long spine, not in 

 a bifurcate hairy appendage! 



7. Macrocheles tridentinus (G. et R. Can.) 



In the same Tijdschrift, v. 45, p. 43, I described and delineated 

 (pi. 5, fig. 101 — 103) a protonympha of Macrocheles tridentinus 

 (G. et R. Can.) under the name of deulonympha I This was a 

 severe mistake of mine, as a deutonympha must be provided with 

 a long peritrema, not with a very short handle-sliaped peritrema, 

 as are only known in protonymphae! 



8. Pachylaelaps furcifer Oudms. nov. sp. 

 (With Plate 11 fig. 5—9.) 



Nympha generans feminina. Length 880 ,«. — Colour egg- 

 yellow. — Shape resembling that of the creature called P. striglfer 

 var. siciilus by Rerlesk (Ac. Myr. Scorp. Ital. 64. 5.) but relat- 

 ively wider and still more shouldered, — Texture. Chitinized parts 

 with large scales; unprotected parts finely wrinkled.
